Listy, 94, 1993, 1, The authors present their experience concerning the time-delay in 357 patients with acute myocardial infarction admitted to the coronary unit over the years 1988--1991. This time indicator was evaluated by using two approaches, i.e. the global time-delay (the time between the onset of the patient's complaints and his/her admission to the coronary unit) and patient's time-delay (the time between the onset of the patient's complaints and his/her decision to notify the health care service). Arbitrary criteria were set up: 10 hours for the former and 5 hours for the latter parameter. The established criteria were met by 40 % of the patients. Only 24 % of the patients presented at the coronary unit within 6 hours, and these could receive thrombolytic treatment. The decision time (patient's time-delay) amounted that the education level of our population has to be enhanced so as to increase the number of patients with acute myocardial infarction presenting at the coronary unit at an early stage.

INCIDENCE OF MALIGNANT TUMORS IN SLOVAKIA I. INCIDENCE VALUES AND TRENDS OVER THE YEARS 1968--1989 OBSITNIKOVA, A., KRAMAROVA, E., PLESKO, I., VLASAK, V. Bratisl. lek. Listy, 94, 1993, 1, In the period from 1968--1989 an increase in the overall incidence of malignant tumors was recorded in men. Of the individual localizations a particularly marked increase was recorded in tumors of the lung, followed by tumors of the oral cavity, pharynx, esophagus, pancreas, urinary bladder, kidney (related to smoking), as well as of the testis and prostate gland. In women the values of overall incidence were lower and the trends were relatively stabilized. This is due to the relatively slow increase in the incidence in cancer of the breast and female reproductive organs and to the slight increase in cancer of the lung. Cancer of the kidney, urinary bladder and pancreas exhibited increased incidence. Low values, stabilized and even decreasing trends were recorded in the incidence of cancer of the oral cavity, pharynx, esophagus, and larynx, as compared to values found in men. In both sexes the incidence of cancer of the stomach showed a pronounced decrease, while the incidence of cancer of the colon and rectum was increasing. A smaller or greater rise was found also in the incidence of tumors of the hematopoietic and lymphatic tissues (except Hodgkins's disease). The trends observed in the incidence of malignant tumors in Slovakia are suggestive of their uncontrolled course, not affected by preventive measures. Yet the findings provide important information for directing the measures so as to aim at localizations of priority. (Tab. 2, Fig. 7, Ref. 20.)

STUDY OF SOME BIOCHEMICAL PARAMETERS IN THE BLOOD OF PATIENTS DURING OPEN HEART SURGERY II. MALONDIALDEHYDE, SUPEROXIDE DISMUTASE AND CATALASE AS INDICATORS OF GENERATION AND ELIMINATION OF FREE OXYGEN RADICALS BARTA, E., CORNAK, V., PECHAN, I., LUKNAROVA, O., VERCHOVODKO, P., RENDEKOVA, V. Bratisl. lek. Listy, 94, 1993, 1, Investigation of cardiosurgical patients have provided evidence for the generation of free oxygen radicals during open heart surgery. The finding of increased plasma malondialdehyde concentrations, considered to be an indicator of lipid peroxidation in cell membranes, is suggestive of this process. Simultaneously, the antiradical capacity of tissue was found to exhibit a decreasing trend, as established by the levels of superoxide dismutase and catalase in erythrocytes of peripheral blood which tended to diminish. The funding that no changes in the studied parameters were observed in the blood from the coronary sinus taken before and after interruption of coronary blood flow demonstrates that the commonly applied protection of the myocardium by hypothermic cardioplegic solution and topical cooling of the heart is effective in suppressing radical formation. (Fig. 5, Ref. 36.) Key words: cardiosurgery; free oxygen radicals; lipid peroxidation; antiradical capacity of tissue.

EFFECT OF MIDDLE-MOLECULAR NINHYDRIN-POSITIVE SUBSTANCES ISOLATED FROM THE RAT MYOCARDIUM ON ARYLAMIDASE ACTIVITY IN RAT BLOOD SERUM CHAVKOVA, Z., SURZIN, J., ADAM, J. Bratisl. lek. Listy, 94, 1993, 1, Protein-free extract from the myocardium of control rats and the majority of its fractions were found to stimulate arylamidase activity. Ethanol administration to rats for 1, 3 or 7 weeks increased the amount of fractions which displayed an inhibitory effect. The observed changes were probably due to enhanced protein degradation and/or to decreased amino acid incorporation into proteins following ethanol administration. (Tab. 4, Fig. 2, Ref. 19.)

Bratisl. lek. Listy, 94, 1993, 1, The authors' 10-year experience with the treatment of 134 patients suffering from ulcerative colitis is presented. The standard with sulfasalazine proved successful in mild forms of the disease, yet preparations containing only 5-aminosalicylic acid had to be administered to patients with intermediate and serious forms of the disease. The authors recommend to individualize treatment with corticoids and antibiotics and to reserve this approach for severe conditions. The use of supplementary therapeutic procedures, particularly administration of drugs affecting the immune system, is still a rather controversial issue. (Tab. 3, Ref. 24.)

CELIPROLOL ENHACES THE MICROCIRCULATION OF SUBCUTANEOUS TISSUE AND CALF MUSCLE IN ESSENTIAL HYPERTENSION PECHAN, J., CESNAKOVA, Z., BALAZOVJECH, I. Bratisl. lek. Listy, 94, 1993, 1, The microcirculation of the subcutaneous tissue and of the muscles of the extremities is changed already in the early stage of essential hypertension. Insight into the effect of celiprolol, a beta blocker of the third generation, on tissue microcirculation is of both pathogenetic and therapeutic value. On using the method of Na131I tissue clearance, the effect of celiprolol on the microcirculation of subcutaneous tissue and on muscles of the extremities was studied in 21 patients with essential hypertension. Celiprolol was administered orally in the daily dose of 300 mg. After one-week administration celiprolol significantly reduced mean arterial pressure and significantly increased the microcirculation in the subcutaneous tissue of the hand and crus as well as in the calf muscle. Celiprolol was thus found to increase the microcirculation in those tissues of the extremities in which its decrease was recorded before onset of the treatment. The obtained results may be of therapeutic value particularly in patients suffering from ischemia of the lower extremities. (Fig. 2, Ref. 19.) Key words: celiprolol; essential hypertension; microcirculation of the extremities.

ELECTRON MICROSCOPIC IMMUNOLOCALIZATION OF RIBOSOMAL RIBONUCLEOPROTEINS BY AUTOANTIBODIES OF PATIENTS WITH SYSTEMIC LUPUS ERYTHEMATOSUS BARAN, V., BARANOVA, Z., BARANOVA, D. Bratisl. lek. Listy, 94, 1993, 1, Serum of patients against rRNP was tested by Western blot method. Four ribonucleoproteins (15, 16, 36 and 38 kDa) specifically reacted with the antiserum used. The autoantibodies were used for immunolocalization of antigenic structures by immunogold method on ultrahin cryosections of hepatocytes, cumulus cells of antral follicle and spermatocytes. Mice and hamsters were used. The cytoplasm appeared to be labelled most intensively. Gold particles were loosly arranged in the cytoplasm (cumulus cells) or they were associated with endoplasmatic reticulum (hepatocytes). Nucleoli were labelled by a lower incidence of the marker. Gold particles were found over the dense fibrillar component bordering on the granular component. In the cytoplasm individual gold particles were observed. (Fig. 7, Ref. 31.)

CATECHOLAMINES AND BLOOD PRESSURE CHANGES DURING LOADING TESTS IN TYPE 1 DIABETIC PATIENTS PONTUCH, P., VOZAR, J., SEDLAK, T., KASPEROVA, V., KRATOCHVILOVA, H. Bratisl. lek. Listy, 94, 1993, 1, The influence of metabolic control on catecholamine secretion and blood pressure during upriglet posture, mental stress and physical exercise was studies in 34 normotensive normoalbuminuric type 1 (insulin-dependent) diabetic patients without autonomic neuropathy. A poor metabolic control did not induce different changes in blood pressure and plasma catecholamines as compared to a good metabolic control, except for an exaggerated rise in plasma adrenaline in patients with asymptomatic hypoglycemia. The lack of correlation between plasma catecholamines and blood pressure suggest that some other factors are also involved in the hemodynamic reaction to mental stress and physical exercise in diabetic patients.

IMMUNOTHERAPEUTIC PRINCIPLES IN THE MANAGEMENT OF CANCER ORLIK, O. Bratisl. lek. Listy, 94, 1993, 1, Numerous clinical and experimental immunological studies have shown that the activity of the immune system plays a decisive role in the course of tumor -- macroorganism interaction. The aim of the present paper was to characterize the basic principles which should be taken into consideration in the complex strategy of cancer management. The best therapeutic effect can be achieved when the immune system is changed from the state of tumor-protective activity into tumor-destructive activity. This can be achieved by the combined effect of three synergistic procedures: (1) elimination of the suppressive influence of tumor cells of the immune system; (2) elimination of the suppressive activity of the immune system; (3) stimulation of anti-tumor effector cell populations of the immune system.

MOLECULAR MEDICINE AND NEW ETHICAL PROBLEMS SAMEL, M. Bratisl. lek. Listy, 94, 1993, 2, The introduction of new methods into medicine, such as recombinant DNA, production of monoclonal antibodies, and particularly polymerase chain reactions, yielded much knowledge and information in fields like preventive medicine (prenatal screening), reproduction strategies (preimplantation diagnosis of genetic defects), molecular diagnosis (oncological and infectious diseases), gene therapy, etc. In many areas the practical use of these sophisticated approaches has become technically feasible yet due to the high cost involved it is still limited. The introduction of some screening programs will be associated with ethical problems of serious impact. To date we can already establish presymptomatic diagnosis of some progressive diseases for which however no therapy is available. Potential abuse of confidential genetic information as well as the possibilities of using gene therapy for "corrective eugenics" are loaded with serious ethical problems. Prospective doctors have to be prepared for this situation in the course of undergraduate studies of medicine. (Ref. 11.) Key words: molecular diagnosis; genetic screening; gene therapy; ethical problems; training in medicine.

ANTIOXIDATIVE PROPERTIES OF SOME CARDIOACTIVE SUBSTANCES MISIK, V., ONDRIAS, K., GERGEL, D. Bratisl. lek. Listy, 94, 1993, 2, Calcium entry blockers reduce the ischemia--reperfusion induced damage to the myocardium. Free oxygen radicals play a role in the pathogenesis of this injury. The mechanism of the protective action of calcium entry blockers is unknown in these conditions and appears to be independent of the blockade of slow calcium channels. As demonstrated in this paper, the calcium entry blockers nifedipine, verapamil and diltiazem are effective scavengers of free oxygen radicals and this characteristic may be importantly involved in their protective effect against myocardial damage induced by ischemia and reperfusion. The prooxidative capacity of the antineoplastic drug cisplatin is assumed to play a role in the mechanism of its renal toxicity action. The presented study showed that the new antioxidative substance with antiarrhythmic and antihypoxic properties -- stobadine -- succeeded in inhibiting the prooxidative effect of cisplatin. Our findings suggest that administration of cisplatin along with antioxidants may result in a protective effect against the renal toxicity of cisplatin. (Fig. 5, Ref. 38.) Key words: antioxidants; free radicals; lipid peroxidation; calcium blockers; stobadine; cisplatin.

DIAGNOSTICS OF ECHINOCOCCOSIS IN THE POPULATION OF SLOVAKIA HAVASIOVA, K., STEFANCIKOVA, A., CERMAN, J. Bratisl. lek. Listy, 94, 1993, 2, Serologically diagnosed cases of echinococcosis in man occurring over the years 1970--1990 are reported. In the given period 292 serum samples were examined obtained from patients clinically suspect of echinococcosis, either with or without indication of localization in different organs. Of the total of 22 serologically positive patients echinococcal cysts were found in the liver in 17 patients (77.27 %), in the lungs in three (13.63 %) and in two patients the localization was not established. The patients with positive serological finding were within the age range of 33 to 68 years, with the exception of one 11-year-old boy. The value of serological examination of echinococcosis in the subjects involved in our study is highlighted by the findings in those patients who underwent surgery. Both the positive and the negative serological results were confirmed by the surgical findings of the presence or absence of echinococcus. (Tab. 3, Ref. 22.) Key words: echinococcosis in man; serological diagnosis. Helmintologicky ustav SAV v Kosiciach Address for correspondence: Ing.

INHIBITION OF HUMAN IMMUNODEFICIENCY VIRUS REPLICATION IN CELL CULTURE BY AZIDOTHYMIDINE (AZITIDIN, LACHEMA) SCHMIDTMAYEROVA, H., MAYER, V. Bratisl. lek. Listy, 94, 1993, 2, The inhibitory effect of the Czecho-Slovakia azidothymidine (AZT) preparation Azitidin (Lachema) on HIV 1 infection was studied in vitro. Its efficacy was compared with that of the approved AZT preparation Retrovir (Burroughs-Wellcome Co.). HIV 1 infected MT4 cells were cultivated in media containing different concentrations of Azitidin or Retrovir. Complete inhibition of virus production (reverse transcriptase activity) and of the cytopathic effect of HIV 1 was seen at the concentration of 0.1 Ýmol of either preparation. Complete inhibition of viral antigen induction was recorded at the concentration of 1 Ýmol. In the light of the obtained results we can conclude that Azitidin inhibits HIV 1 replication in vitro and its efficacy is fully comparable to that of Retrovir. (Tab. 4, Fig. 2, Ref. 17.)

EFFECT OF ETHANOL ON THE OCCURRENCE OF PEPTIDES WITH ANTIBACTERIAL ACTIVITY IN THE RAT MYOCARDIUM ADAM, J., SURZIN, J., CHAVKOVA, Z., GREGA, B. Bratisl. lek. Listy, 94, 1993, 2, The effect of 7 % ethanol on the peptide content in the myocardium was studied during prolonged exposition. The protein-free extract from the myocardium of controls as well as experimental groups following 1--8 weeks ethanol administration contained peptides with antibacterial activity. Long-term ethanol administration resulted in changes in physico-chemical properties of peptides both compared with controls and also among the experimental groups mutually. The changes were manifested by differences in the elution profiles following gel chromatography and RF values after electrophoresis or by different amino acid composition. The results are compared with the influence of peptides on the growth of bacterial cultures S. aureus. Ethanol administration induced diminution of the diameter of the inhibitory zones. This effect was most marked in the group fed with ethanol for 3 and 8 weeks. (Fig. 5, Ref. 17.) Key words: alcohol; peptides; amino acid; S. aureus; myocardium.

NEUROENDOCRINE ACTIVATION AND VENTRICULAR REMODELING AFTER ACUTE MYOCARDIAL INFARCTION -- INFLUENCE OF ANGIOTENSIN-CONVERTING-ENZYME INHIBITORS DUBRAVA, J., CAGAN, S. Bratisl. lek. Listy, 94, 1993, 2, Neuroendocrine activation, which begins early after myocardial injury, participates significantly in the pathogenesis of acute myocardial infarction and its complications. Plasma concentrations of catecholamines, arginine vasopressin and atrial natriuretic factor were highest on admission. Activation of the renin-angiotensin-aldosterone system reached its peak after 72 hours. In patients with acute myocardial infarction and heart failure the neuroendocrine activation was more intensively expressed. This study presents clinical consequences of neuroendocrine activation. Its relation to ventricular remodeling, as a potentially maladaptive mechanism is especially discussed. Angiotensin-converting-enzyme inhibitors influence favorably both neuroendocrine activation and ventricular remodeling after myocardial infarction. At present 7 ongoing extensive multicenter trials are to determine if such a therapy would lead to a better survival and attenuate the progressive deterioration of heart function after myocardial infarction. (Fig. 2, Ref. 24.) Key words: acute myocardial infarction; neuroendocrine activation; ventricular remodeling; angiotensin-converting-enzyme inhibitors.

DOES SHORT-TERM HIGH-FREQUENCY JET VENTILATION DAMAGE THE TRACHEOBRONCHIAL MUCOSA? JAVORKA, K., PLANK, L., ADAMICOVA, K., KULISEK, V. Bratisl. lek. Listy, 94, 1993, 2, In anesthetized rabbits, the occurrence of histopathological changes was studied above below the level of the endotracheal tube opening after one-hour high-frequency jet ventilation (f=150.min-1, Pin=70--90 kPa, Ti=0.5) with nonhumidified air and oxygen mixture (FiO2=0.6). The findings were compared with those obtained in intact rabbits and in rabbits which were inhaling nonhumidified air from the environment spontaneously via the endotracheal tube. Mechanical obstruction of the airways by mucus or necrosis of the mucous membrane was not observed. The major histopathological changes characteristic of inflammation and mechanical damage of the mucosa were recorded above the opening of the endotracheal tube. Towards the main bronchi the degree of the injury was decreasing. (Tab. 2, Fig. 2, Ref. 11.) Key words: high-frequency jet ventilation; tracheobronchial mucosa; histopathological changes.

SERODIAGNOSIS OF LARVAL TOXOCARIASIS IN SLOVAKIA STEFANCIKOVA, A., HAVASIOVA, K., DUBINSKY, P. Bratisl. lek. Listy, 94, 1993, 2, The results of serological examinations performed over the years 1986 to 1990 in patients suspect of larval toxocariasis, coming from different Institutes of National Health in Slovakia, are reported. Seropositivity was within the range from 9.38 to 23.56 %. The five-year average was 17.72 %, with a predominance of seropositivity in the country. Age-related analysis of the series of patients did not show any significant difference of seropositivity in children and adults (18.00 and 17.21 % respectively). Higher seropositivity rates were found in boys (20.73 %) compared to girls (14.62 %). This was found to be reversed in adults, where women had higher seropositivity rates than men (20.61 and 12.08 % respectively). The ocular of larval toxocariasis showed a higher prevalence in adults.

Bratisl. lek. Listy, 94, 1993, 2, The aim of the paper was to assess the contribution of transesophageal atrial stimulation in bradyarrhythmic derangements of the heart rhythm. The main purpose was to make the diagnostic simpler and safer. Since the series of patients involved is small, our results are to be considered as a preliminary report. (1) When only dysfunction of the sinoatrial node is involved, the method yields results comparable to those obtained by invasive electrophysiological examination. Compared to the latter, invasive approach, the great advantage of the presented method is its repeatability and simplicity.

CHANGES OF HEMOSTASIS IN ISCHEMIC HEART DISEASE HROMEC, A., OKRUCKA, A., MURIN, J., KASPER Jr., J. Bratisl. lek. Listy, 94, 1993, 3, The relationship between changes in blood coagulation, the occurrence and severity of risk factors of ischemic heart disease and the clinical condition of the patient was investigated. The at risk group of patients (42.2 %) had more than 3 pathological parameters. Intravascular blood coagulation was not activated in any of the patients. In patients with acute myocardial infarction (MI), 62.2 % had more than 3 pathological parameters on the first day of MI development. Demonstrable activation of intravascular blood coagulation was found in 28.2 % of these patients. On day 5 of MI, activation of intravascular blood coagulation was recorded in 57.7 % of the patients treated by classical approach and in 15.4--30.8 % of the patients on thrombolytic treatment. In the at risk group, primary hemostasis and the fibrinolytic system were more affected, in patients with MI the whole hemostatic mechanism was involved. On day 5 of MI, in patients with classical therapy pathological laboratory findings still persisted or were even more deteriorated, particularly increases in fibrinogen level. At that time, in patients on thrombolytic therapy no substantial changes of initial values were recorded. No correlation was found to exist between changes in hemostasis and the risk profile or between changes in hemostasis and the clinical severity of MI. The obtained results justify the administration of antithrombotic substances, especially in patients with unstable angina pectoris. On observing time constraints, administration of thrombolytics is justified in MI. (Fig. 9, Ref. 25.)

LATE RESULTS OF REVASCULARIZATION OPERATIONS FOR ATHEROSCLEROTIC OCCLUSIVE ARTERIAL DISEASE OF THE LOWER EXTREMITIES MAZUCH, J., MACHAN, L., HERCZEGH, S., PELC, J., MISANIK, J. Bratisl. lek. Listy, 94, 1993, 3, The authors evaluated their 15-year experience with revascularization operations for atherosclerosis obliterans (ASO) of the lower extremities. Over the period from 1975 to 1990, 1112 patients with ASO were admitted to their department and in 674 (60.6 %) of them revascularization operation was performed. Direct revascularization surgery (bypass, desobliteration, angioplasty) was performed in 318 (47.2 %) patients and indirect revascularization, sympathectomy in 326 (52.8 %) patients. On evaluating the long-term results of aortobifemoral (AF2), femoropopliteal (FP) and femorocrural (FC) bypasses the following long-term patency was established: AF2 bypass -- patency up to 2 years 92 %, up to 5 years 90 %, up to 10 years 76 %, up to 15 years 75 %; FP bypass -- patency up to 2 years 90 %, up to 5 years 84 %, up to 10 years 62 %, up to 15 years 46 %; FC bypass -- patency up to 2 years 63 %, up to 5 years 50 %, up to 10 years 25 %. Complications developed in 10 %, the mortality rate was 2.5 % and 8 % in FP and AF2, respectively. The obtained results are comparable with the data published in the literature. The authors achieved the best results in the suprainguinal region with AF2 bypasses on using mostly dacron prostheses and in the infrainguinal region FP bypasses on using the autologous great saphenous vein.

QUANTITATIVE ULTRASTRUCTURE OF THE HEART MUSCLE OF JAPANESE QUAILS DURING HYPODYNAMISM, HYPERGRAVITATION AND COSMIC FLIGHT BOZNER, A., BODA, K., DOSTAL, J., MATEJKOVA, Z., DEVECKA, V. Bratisl. lek. Listy, 94, 1993, 3, The experimental work aimed at the quantitative ultrastructure of the myocardial cells of the Japanese quail Coturnix coturnix japonica during hypergravitation, hypodynamism and space flight in a Soviet satellite. For the determination of quantitative changes of the myocardial ultrastructure a morphometrical method was used with parameters like the number of mitochondria, average mitochondrial size, relative mitochondrial volume, deficiency of cristae and relative volume of myofibrils. The quails were observed in 3 groups. The absolute control consisted of quails living in normal Earth conditions, in the laboratory group the quails were exposed to conditions of hypergravitation and hypodynamism in a specially constructed centrifuge, and in the flying group the quails were exposed to space flight in a Soviet orbital station MIR. In the group of absolute controls no pathological changes of the myocardial ultrastructure were found. In the flying group there were no significant changes, with the exception of decreased relative volume of myofibrils, which however agrees with the findings on symptoms corresponding to human and animal heart weakness during space flights. In the laboratory group, pathological changes were observed in each of the fractions. The most significant pathological findings were found in the group controls in the center and in hypergravitation combined with hypodynamism. It can be concluded that the laboratories can simulate conditions induced by the start and flight of space ships. (Fig. 2, Ref, 8.)

MORPHOLOGICAL FINDINGS IN SOME MODELS OF ACUTE EXPERIMENTAL PANCREATITIS HUTAN, M., ONDRIAS, F., NITRAYOVA, O., POPOVIC, J. Bratisl. lek. Listy, 94, 1993, 3, Morphological changes found in two models of acute experimental pancreatitis are presented. Acute pancreatitis was induced in rats by the method of ligation of the lateral pancreatic ducts and by the method of the blind duodenal loop. After four hours the animals were sacrificed and processed for light and electron microscopic examination. Changes indicative of edematous and necrotizing pancreatitis were recorded. In the electron microscopic picture the predominant findings were disintegration of organelles of acinar cells and the appearance of numerous vacuoles and autophagosomes. The presented models of pancreatitis are considered to be suitable for further research into the pathogenesis and therapeutic intervention of acute pancreatitis in rats. (Fig. 15, Ref. 8.)

OUR EXPERIENCE WITH ENDOSCOPIC THERAPY OF CHRONIC PANCREATITIS DITE, P., ZBORIL, V., PETRIKOVA, A., CIKANKOVA, J., TESAKOVA, H. Bratisl. lek. Listy, 94, 1993, 3, Endoscopic drainage is a modern and effective therapy in patients with chronic obstructive pancreatitis. The authors demonstrate their experience with this therapy in 20 patients. It resulted in pain disappearance in 60 % of the patients and in body weight increase within 1 year after therapy in 55 % of the patients. Steatorrhea was not significantly influenced by the therapy. The main complication of endoscopic therapy were frequent restenoses (30 %). (Tab. 4, Fig. 2, Ref. 12.) Key words: chronic obstructive pancreatitis; endoscopic papillosphincterotomy of pancreatic duct; restenosis as a complication of papillosphincterotomy.

STUDY OF SELECTED BIOCHEMICAL PARAMETERS IN THE BLOOD AND LIVER OF RATS AFTER ADMINISTRATION OF Ñ-ESCIN ULICNA, O., VOLMUT, J., KUPCOVA, V., BRIXOVA, E. Bratisl. lek. Listy, 94, 1993, 3, The effect of Ñ-escin on selected parameters of carbohydrate and lipid metabolism was studied in blood and liver tissue. The aim was to established whether its administration would result in steatosis of the liver. Rats were given sodium salt of Ñ-escin in water solution orally by gavage in the dose of 10 mg/kg or 70 mg/kg. Analysis of blood samples and liver tissue showed that administration of Ñ-escin to healthy rats did not induce any substantial changes in the metabolic parameters studied. The rats did not develop steatosis. The biological half-life of antipyrine was only sightly prolonged. (Tab. 3, Fig. 1, Ref. 10.)

Listy, 94, 1993, 3, Infectious complications have remained the most frequent cause of morbidity in surgical patients, and that despite the constantly broadening range of up-to-date antimicrobial drugs administered prophylactically and therapeutically, the improved methods of cultivating microorganisms and of establishing sensitivity to antibiotics. Infections in surgical patients lead to prolonged hospitalization, prolonged working disability, and to increased cost of treatment. Considerable economic consequences of infections in surgical patients are demonstrated on the basis of the authors' clinical material and possibilities of preventing infections and of their treatment are also discussed.

ON THE PROBLEM OF ANTIBIOTIC TREATMENT AT AN INTENSIVE CARE UNIT KOHN, R., KRCMERY Jr., V. Bratisl. lek. Listy, 94, 1993, 3, The results of antibiotic treatment administered to 78 patients within one year are reported. Due to the nosocomial nature of the infections, the serious overall condition of the patients and the associated diseases, the prognosis remained unfavorable despite adequate antibiotic treatment. In the group of patients on dialysis ofloxacin and ciprofloxacin proved effective. Patients with exacerbation of chronic bronchitis responded well to doxycycline. In the treatment of infections of the urinary tract, the known favorable effect of cotrimoxazol was confirmed. Of the group of 78 patients with transitory or permanent cardiostimulation, 18 received antibiotic treatment. In 6 of them with transitory cardiostimulation antibiotics were given as a prophylactic measure, 4 patients developed febrile conditions after implantation of the cardiostimulator and 8 patients received antibiotics due to infections of the respiratory and urinary tract. After implantation of the cardiostimulator 60 patients (77 %) did not require antibacterial treatment. (Ref. 5.) Key words: antibiotic treatment; nosocomial infections; intensive care unit.

Qualified estimations suggest that subjects above 60 years of age represent more than one half of the daily clientele of a district physician. The basic characteristics of elderly people are their fragility, readily attained decompensation and diminished adaptability. Their hospitalization is thus demanding and involves risks. Geriatric patients require comprehensive care. Treatment without removing their social fears and psychic anxiety does not yield adequate effect. Active involvement of relatives into the program of care may prove a beneficial contribution. The main aim is to provide comprehensive health and social care primarily at the patient's home. (Ref. 10.) Key words: comprehensive care of the elderly; geriatrics; geriatric legislature. Address for correspondence: Ludovit Sevcik, student, 3.

RELATIONSHIP OF SPEECH TO THE RIGHT AND LEFT CEREBRAL HEMISPHERE CERNACEK, J. Bratisl. lek. Listy, 94, 1993, 4, Verbal speech functions are localized in right-handed subjects practically exclusively and in left-handed ones mostly in the left hemisphere. Much information on these functions has been obtained by studying patients affected with spontaneous derangements, as well as after hemispherectomy, after severing the corpus callosum, and during electric stimulation of the brain in neurosurgical procedures. In the presylvian region of the hemisphere dominant for speech, a region for the production and indentification of speech was found, surrounded by an area for short-term memory. The predominance of the right ear in recognizing verbal stimuli, established by the dichotic test, applies to the population rather than to the individual. The substance of verbal dominance of the left hemisphere lies in its pre-eminent capacity to distinguish rapid acoustic sequences and to produce them. Observations made on deaf-and-dumb patients with sign language have demonstrated that humans possess a genetically determined ability to develop speech, regardless the modality. Speech functions of the right hemisphere concern mostly nonverbal prosodic components of speech. (Ref. 54.) Key words: speech; dominance of hemispheres; left hemisphere; right hemisphere.

Listy, 94, 1993, 4, The study is focused on genetic characterization of the child population of the Orava region, where genetic isolates persisted as long as the middle of this century. Active screening for genetic pathology over a period of 5 years involved examination of 1058 children aged 0--14 years. Genetically determined pathological conditions were diagnosed in 757 children, which represents 1.67 % of the child population of this region. Chromosomal aberrations were established in 55 children (0.12 %), monogenic diseases in 193 children (0.43 %), of these autosomal recessive defects in 88 children (0.19 %), and multifactorially determined conditions in 478 children (1.06 %). Focal occurrence of an inherited disease was not recorded. Genetic affliction of the population studied was found to be comparable to that in panmictic populations. Thew occurrence of diseases inherited as autosomal recessive traits suggests that the influence of genetic isolates does no longer persist in Orava. (Tab. 1, Ref. 10.) Key words: genetic epidemiology; genetic isolates; genetically determined pathological conditions; genetic affliction of the population.

ENZYMES IN TUMORS OF THE MAMMARY GLAND -- HISTOCHEMICAL STUDY OF THE STROMA OF MAMMARY GLAND CARCINOMAS LONGAUER, F., BILCIK, P. Bratisl. lek. Listy, 94, 1993, 4, The results obtained in histochemical examination of the stroma of mammary gland carcinomas allow to draws the following conclusions. The reaction to alkaline phosphatase proved suitable for detecting proliferation zones in the stroma of mammary gland carcinoma. Proliferation of fibroblasts, myofibroblasts, endothelial cells, and possibly also of other cells is involved. At present, myofibroblasts can not be cytoenzymatically differentiated from fibroblasts. The reactions to acid phosphatase and nonspecific esterase provide a quick and reliable picture on the amount of macrophages. The combined reaction to alkaline phosphatase and dipeptidylpeptidase IV in the same section indicates that individual segments of the newly formed capillary bed in the stroma of the tumor, i.e. the arterial, intermediary and venous segment, are differentially equipped by these enzymes. The activity of several enzymes in carcinomal stroma with typical stripe- and wave-like architecture can most probably be assigned to fibroblasts and myofibroblasts. Between the enzymatic activity in the stroma and the type or differentiation of the carcinoma no relationship was established. (Tab. 2, Fig. 7, Ref. 35.)

USE OF TUMOR MARKER CA 19--9 IN DIAGNOSIS OF CARCINOMAS OF THE PANCREAS KAUSITZ, J., LESNY, P., BELAN, V. Bratisl. lek. Listy, 94, 1993, 4, The contribution of the tumor marker CA 19--9 to differential diagnosis between malignant and nonmalignant diseases of the pancreas was assessed in a group of 120 patients. On using border values of CA 19--9 80 U/ml, its sensitivity was found to be 84.4 % and its specificity 84.8 % for carcinomas of the pancreas. Correlation of CA 19--9 values with results of computer tomography and endogenous retrograde cholangiopancreatography in the patients studied yielded an over 80 % accordance. In the light of the obtained results, the authors consider determination of CA 19--9 levels to be a suitable method supplementing the imaging examination methods in suspect carcinoma of the pancreas.

USE OF HIGH FREQUENCY MODULATED CONTINUOUS POSITIVE AIRWAY PRESSURE IN EXPERIMENTAL RESPIRATORY DISTRESS SYNDROME AND PULMONARY EDEMA JAVORKA, K., KULISEK, V., DEMIDOV, V., GECELOVSKA, V., SUTARIK, L. Bratisl. lek. Listy, 94, 1993, 4, The effect of high frequency (f=300.min-1) modulated continuous positive airway pressure (CPAP) (0.49 kPa) was compared with that of CPAP without modulation (0.49 kPa) in 24 anesthetized rabbits in experimental respiratory stress syndrome (RDS) and pulmonary edema. RDS was induced by single excessive lavage of the lung on using the inpulse and expulse effect of high frequency jet ventilation. Pulmonary edema was elicited by i.v. administration of a mixture of fatty acids. Decreased dynamic compliance of the lung and increased respiration work and rate were recorded both in experimental RDS and pulmonary edema. In RDS paO2 was reduced and paCO2 increased. In pulmonary edema, despite diminished respiration volume, ventilation was enhanced by the higher respiration rate and both paO2 and paCO2 were reduced. Application of CPAP resulted in normalization of blood gases. Modulated CPAP, compared to CPAP without modulation, further decreased paCO2 and increased paO2. The results obtained in experimental models of RDS and pulmonary edema in rabbits show the beneficial effect of high frequency modulated CPAP by pressure oscillation on values of blood gas tension.

Listy, 94, 1993, 4, In 25 patients with chronic renal failure, the levels of glycemia and immunoreactive insulin (IRI) were determined in one-hour intervals over the period of eight-hour hemodialysis. The study was performed in hemodialysis with and without 200 mg% glucose in the dialysis solution. The mutual behavior of the two substances was evaluated. In patients on a chronic hemodialysis program the level of IRI was found to depend on elimination, secretion, and endogenous control of IRI. The internal processes may be involved to a more important extent in achieving the definitive levels of IRI (middle-molecular substance) than its elimination by hemodialysis. The actual regulator -- glucose (low-molecular substance) need not change its level significantly in this process. (Fig. 8, Ref. 5.) Key words: plasma immunoreactive insulin; hemodialysis; middle-molecular substances.

STUDY OF THE EFFECT OF ROTATING MAGNETIC FIELD ON THE GROWTH OF DEALS' GUINEA PIG SARCOMA SUBCUTANEOUSLY TRANSPLANTED INTO GUINEA PIGS SCHWARTZ, E., SVEJNOCHOVA, M., SIPOSOVA, E., HONZATKOVA, Z. Bratisl. lek. Listy, 94, 1993, 4, The effect of rotating magnetic field (RMF) was studied on the growth of Deals' guinea pig sarcoma (DGPS) transplanted subcutaneously into the inguen of guinea pigs. The 0.2 ml of transplanted suspension contained 1.5--2.0x106 of vital DGPS cells. Over a period of 24 days the animals were daily two times exposed to RMF for 3 hours. The animals were sacrificed in chloroform anesthesia, the inguinal tumors, lungs and hearts were removed and weighed. The following findings were recorded: 1. RMF inhibited the growth of DGPS cells in experimental guinea pigs compared to control animals (p<<0.001); 2. In the experimental animals DGPS cells did not metastasize into the lung parenchyma; 3. The pathological characteristics of the tumors in the experimental and control group of guinea pigs tended to be different. (Tab. 3, Ref. 14.)

CLINICAL PICTURE OF IMPORTED MALARIA AND ITS RELATIONSHIP TO P. FALCIPARUM PARASITEMIA LOUDOVA, J., GIBODA, M., GUTVIRTH, J. Bratisl. lek. Listy, 94, 1993, 4, The paper summarizes the results of clinical examinations of imported malaria in 48 patients, semiimmune foreigners infected with P. falciparum and P. vivax/P. ovale. Of the objective manifestations, hepatosplenomegaly was predominant in P. falciparum infections (34 %), whereas in P. vivax infections its occurrence rate was 19 %. Body temperature over 38 ÊC with shivering had a higher frequency in P. vivax (81 %) compared to P. falciparum (41 %) infections. Pathologically altered hematologic values, particularly mild to medium increase in sedimentation rate, were found in all patients with P. vivax/P. ovale, while in patients infected with P. falciparum only in those whose parasitemia exceeded 10 000 trophozoites in 1 Ýl blood. Reduced values of hemoglobin, hematocrit, and mean erythrocyte volume are indicative of microcytic anemia of mild degree. Biochemical examinations yielded slightly increased values of the thymol turbidity test and mild reduction of serum proteins at simultaneous increase of albumins (8 % of the patients examined). Of the parameters of humoral immunity, there was a rise in immunoglobulin values concerning particularly IgG and IgM, and that in all types of malarial infection studied. Increased values of circulating immunocomplexes had a high frequency rate with all plasmodial species, in P. falciparum infections independently of the degree of parasitemia. (Tab. 7, Ref. 13.)

CONTRIBUTION OF ECHOCARDIOGRAPHY TO DIAGNOSIS AND PREVENTION OF CONGENITAL HEART DISEASES WITH PRIMARILY GENETIC ETIOLOGY KANALIKOVA, K., HALASOVA, E., VANZUROVA, E., STANOVA, L. Bratisl. lek. Listy, 94, 1993, 5, Over the period from January 1982 to June 1989 the authors examined 1723 children and adolescents with congenital heart diseases (CHD), hospitalized in the Institute of Cardiovascular Diseases in Bratislava. Of these patients, 96 (5.6 %) had CHD of primarily genetic etiology: monogenic diseases 51 (3 %), chromosomal anomalies 45 (2.6 %) patients. In indicated cases (polystigmatization, positive family history) the relatives were examined. Echocariographic examination of 203 relatives of patients with genetically determined CHD yielded positive echocardiographic findings in 32 subjects (15.5 %). In relatives of patients with CHD of primarily genetic etiology, even structural changes which hemodynamically are not severe may be of value for individuals who are carriers of pathologic genetic information. Echocardiography is a contribution not only to diagnosis but also to prevention of CHD in association with adequate genetic counselling. (Tab. 4, Ref. 7.)

EFFECT OF CYCLOSPORIN A ON THE DEVELOPMENT OF TOXOPLASMA GONDII IN MUSCELS AND BRAIN OF MICE HULINSKA, D., SYKORA, J., ZASTERA, M. Bratisl. lek. Listy, 94, 1993, 5, Presented are histological and electron microscopic findings of alterations in the muscles and brains of mice infected with T. gondii and suppressed with CyA during infection. Cya in the acute phase of infection promoted parasitemia. In the chronic stage it modified the formation of clustered cysts. Following repeated infection active tachyzoites appeared in the repleted macrophage populations of the interstitium. Polymyositis with manifested muscle fiber atrophy and allergic toxoplasmic encephalitis in the acute phase of infection is caused by: 1. active penetration of tachyzoites into non-phagocytizing muscle and nerve cells, 2. toxins (necrotizing enzymes) released by the destroyed reticuloendothelial cells due to rapid multiplication of tachyzoites and pseudocysts, 3. immunologic processes affecting factors regulating the multiplication rate and subsequent transformation of tachyzoites into cystozoites, and vice versa. The altered tissue tropism during toxoplasmic infection, i.e. suppression of the granulating tissue and fibrosis, results in a necrotizing process induced by tachyzoites or in the rupture of cysts.

MOLECULAR GENETIC ANALYSIS OF DELETIONS IN PATIENTS AFFECTED WITH PROGRESSIVE MUSCULAR DYSTROPHY OF THE DUCHENNE AND BECKER TYPE KADASI, L., GECZ, J., SAKSOVA, L., THURZOVA, M. Bratisl. lek. Listy, 94, 1993, 5, Methods of molecular genetics (Southern's hybridization and DNA amplification by the PCR method) were used to search the DNA of patients suffering from the Duchenne (DMD) and the Becker (BMD) type of progressive muscular dystrophy for deletions in the dystrophin gene. The series consisted of 29 patients with DMD and 2 patients with BMD. As hybridization probes cloned cDNA sections were used designated as CF56a, CF56b, 1-2a, 2b-3, 4-5a, 5b-7 and 8. With the PCR methods means for exons 8, 19, 45 and 48 were used. No deletion was found in either of the BMD patients. In 13 (44.8 %) of the 29 DMD patients deletion with at least one cDNA probe was found. Most deletions were detected with the probes 8 (46.2 %) and 1-2a (30.8 %). The high proportion of deletions in the etiology of DMD/BMD has both a high differential diagnostic value and allows to make direct prenatal diagnosis as well as to determine transmission in these families with subsequent elimination of the risk of diagnostic error resulting from recombination in DNA diagnosis by means of binding.

BACTERIAL FLORA OF APPENDICES FROM RABBITS WITH ARTIFICIALLY INDUCED APPENDICITIS HUDAC, A., PALICOVA, F., GERYK, B. Bratisl. lek. Listy, 94, 1993, 5, The authors present the results of bacteriological analysis of scrapings from the appendical mucosa of 24 rabbits with appendicitis induced by obstruction of the appendix lumen and of 5 rabbits with healthy appendices (controls). In dependence on the duration of inflammation, the recovery of aerobic bacteria was decreasing and that of anaerobic nonsporulating bacteria was increasing. In the group of anaerobic bacteria, gram-negative rods were predominant (number of isolated colonies: 2973=79.9 %, variation range of occurrence: 105--108 per 1 gram of material) with a remarkable prevalence of the genus Bacteroides and particularly of the species Bacteroides fragilis. Compared to the occurrence in appendices with inflammation, the recovery of bacteria in controls was minimal. The work served as model in studying pathogenesis of acute appendicitis in human medicine. (Tab. 3, Ref. 12.) Key words: acute appendicitis in rabbits; anaerobic bacteria.

ACTIVITY OF MALIC ENZYME SAMEL, M., PULLMANN, R. Bratisl. lek. Listy, 94, 1993, 5, In young rats of different ages of postnatal development the effect of short-term administration of thyroxine (T4) on the activity of malic enzyme (ME) was studied in brown adipose tissue (BAT),liver,heart and kidney. Thyroxine was injected in a dose sufficient to saturate all receptor sites, i.e. 1 microgram per 1 gram of B.W. during 3 consecutive days. The highest activities of ME were found in BAT. An increase in enzyme activities with age was observed in all tissues studied in control animals. Injections of T4 increased the activity od ME in the liver; in BAT a significant increase was found only the younger age group (6 days). In older animals (40 days) with high values in BAT of controls no further increase induced by T4 was observed. In the kidney as well as in the heart no significant changes were found after T4 administration. It is concluded that in developing animals BAT may play a more important role in lipid synthesis than considered so far. (Fig. 1, Ref. 7.)

Listy, 94, 1993, 5, The method of diuretic scintigraphy was used to examine 27 children, aged 2--15 years, with excretion urography findings of dilatation of the upper urinary tract. Vesicorenal reflux was excluded in all the children of the series by classical radiologic cystography. The radionuclide 131I-hippurate was used in 15 children and 99mTc-MAG3 in 12 children. In both groups the parameter T 1/2 was determined as the time of 50 % decrease of activity above the kidney after administration of the diuretic. With both radionuclides the same borderline time of T 1/2 was established. In cases with T 1/2<<10 minutes and preserved kidney function, dilatation of obstructive origin can be excluded with both substances. 99mTc-MAG3, however, has a markedly better imaging capacity and a significantly lower radiation load than 131I-hippurate.
