The patterns of oxygen metabolism in the early posthemorrhagic period]

Investigated all links of oxygen homeostasis of patients in early period afterwards surgical stoppage gastro-intestinal bleeding and urgent intravascular volume replacement. Macrodelivery of oxygen (DO2) was reduced in two and more time in comparison with norm predominant in connection with anemia. In spite of the infringement of transport of oxygen through alveolar-capillary membrane (especially in patients with complications and death in early postoperative period), little affected of degree of hemoglobin saturation by oxygen. Despite decrease of erythrocyte zeta-potential, largely expressed in cases of lethal outcome, considerable infringement of passage through microcirculation vessels is fixed was not. The increase of degree of morbidity and anaerobic metabolism in early postoperative period was accompanied of hyperdynamic hemodynamic reaction. The increase of degree of morbidity was accompanied of increase oxygen deficit owing to infringement of oxidoreduction in fabries also.     

Hemostasis in patients operated on for abdominal hemorrhage. 3. Boundary deviations of hemostasis

The fibrinolytic process in the plasma of patients operated for abdominal haemorrhages have been investigated. The results allowed to conclude that the blockade of fibrinolysis did not effect on the course of the disease. The high level of the inhibitors and of the platelets hypoaggregation can be considered as a cause increased of the recurring gastrointestinal haemorrhages. It was demonstrated that the probability of DIC-syndrome development increased at the aggravation of the patient's state after the operation.     

Relation between the space flight-induced frequency of dominant lethal mutations and the level of allozyme heterozygosity in Drosophila melanogaster populations

Currently, the treatment of falciparum malaria is seriously compromised by spreading drug resistance. We studied the effects of camptothecin, a potent and specific topoisomerase I inhibitor, on erythrocytic malaria parasites in vitro. In Plasmodium falciparum, camptothecin trapped protein-DNA complexes, inhibited nucleic acid biosynthesis, and was cytotoxic. These results provide proof for the concept that topoisomerase I is a vulnerable target for new antimalarial drug development.     

The genotypic evaluation of bulls for the milk productivity of their daughters

Breeding value of stud bulls was evaluated by methods of comparison of daughter and herd-mate productivity for milk production at the reproductive crossing of Red Step and Holstein cattle. It was shown with a sufficient degree of certainty and legitimacy that such methods of comparison of Holstein bull daughters with the cross-bred herd mates without regard to their inheritance may be extensively used.     

The course of the reparative process in patients with gastric and duodenal peptic ulcers (a clinico-statistical study)

Clinico-statistical evaluation of reparative process in 332 gastric ulcer and 294 duodenal ulcer patients revealed factors of objective value to its course. In order of significance the factors rank as follows: area of ulcer, localization, combination with certain mucosal erosions, total fasting acidity, free fasting hydrochloric acid, basal gastric secretion, cardial function, duodenogastric reflux, sex, age, number of cigarettes smoked daily. When studying treatment effects on regeneration in ulcer patients in is necessary to take into consideration basal clinico-endoscopic parameters.     

Optimization of rotatory tests in electronystagmography

The paper discusses optimization of rotatory tests as related to the classification of electronystagmograms. It presents criteria of the efficiency of the action on the vestibular analyzer taking into account statistical properties of different classes of electronystagmograms. The paper shows that the methods of variation statistics should be used to determine the category of action. The method described has been applied to identify an optimal action in the case of electronystagmograms of two classes (normal and pathology of a certain type). An action described as a sequence of delta-impulses of an angular acceleration has been obtained. A higher efficiency of the optimal action on the vestibular analyzer has been shown on the basis of a comparative study.
