[The application of laparocentesis and peritoneal lavage and the analysis of hemo-peritoneal volume in the diagnosis of closed abdominal wound].

Laparocentesis and peritoneal lavage--are simple, quick and informative methods widely applied in surgical practice for diagnosis of closed injury of abdominal cavity organs. Modifications of these diagnostic methods, their combination with possibility of hemoperitoneum volume detection, occurring while the internal organs injury, the results of investigation interpretation permit to broaden their possibilities, peculiarly in the absence of other instrumental diagnostic facilities available.

[Helicobacter pylori prevalence among patients with gastroduodenal diseases in Kiev].

It is for the first time in Ukraine that a study has been made on the epidemiology of H. pylori infection among patients with disorders of the stomach and duodenum. The diagnosis of the infection was done with the aid of various invasive and noninvasive tests, 13C-urea breathing test, a unique for Ukraine and countries of the Western Europe method of examination included. Ascertained among the above category of patients was wide prevalence of H. pylori, which fact confirms its leading etiological role in disorders of the stomach and duodenum once again.

[2-stage rupture of the spleen].

Two-stage ruptures of the spleen are a difficult diagnostic problem of closed abdominal trauma. Diagnostic errors occur in 85% of cases. The causes of the errors are the peculiar pathogenesis of this trauma of the spleen, which has a two-stage character, and the circumscribed position of the pathological focus in relation to the free abdominal cavity. In true two-stage ruptures of the spleen, the pathological focus is delimited by the intact capsule of the organ, in false rupture it is delimited by a complex of factors leading to anomalous block of fibrinolysis in the ++peri-splenic clot which plugs the rupture in the organ and causes temporary arrest of the bleeding. The possible causes of the anomaly are discussed. Six personal cases are analysed, and the diagnostic recommendations in the examination of patients with suspected two-stage rupture of the spleen are generalized.

[Energy parameters of Acetabularia cell membrane].

The energy parameters of the mechanism involved in the action of Acetabularia cell membrane were studied. The resistance of the membrane is found to be near 3 kohm per sq. cm when resting and at the peak of excitation it is much lower (100 ohm/cm(2). The power of the mechanism regulating the action of the membrane during the peak. The total power of the membrane system of Acetabularia is 8 microwatt per sp. cm. reaches 6.5 microwatt/cm(2). The energy consumed by the regulatory mechanism during the action potential is minus 290 plus or minus 20 erg/cm(2) and the total energy dissipation is 20 erg/cm(2). The values of the energy consumed by the cell during the action potential are compared with its energy resource.

[Osmotic homeostasis and radiosensitivity of NKLy lymphosarcoma cells].

In experiments with cells of ascites NKLy lymphoma differing in ploidy and position in the cell cycle, a study was made of the radiosensitivity, osmotic homeostasis peculiarities and thermoradiation changes in potassium content. It was shown that the resistance of osmotic homeostasis of NKLy cells to thermoradiation correlated with their radioresistance and was maximally displayed in cells at the stage of DNA synthesis.
