[Abdominal cavity adhesions. Some issues of pathogenesis, prophylaxis and treatment].

The abdominal cavity adhesions (ACA) constitute frequent consequence of various abdominal cavity diseases and traumas and frequent cause of the abdominal adhesive disease and its complications. In spite of the known pathogenesis of ACA, the surgeons had failed throughout the decades of years to find out the measures and methods of its prophylaxis. There are several causes of such a situation and the main of them is that ACA in its origin constitutes a philogenetically developed defense biologic reaction of organism. Because of the fact, that an organism constitutes the self-regulated biological system, any external inputs (including the treatment), directed on qualitative or quantitative signs of these reactions, meet systemic counteraction and become annihilated. The forced overcome of such a counteraction may cause the development of severe systemic disorders in organism. The only prophylactic measures against ACA, which were already tested throughout the time, are the tactical and technical methods, promoting the reduction of severity of morphological changes in peritoneum and abdominal organs, thus causing reduction of natural reaction of organism. When the adhesions formation is inevitable it is necessary to apply surgical methods of governing such a process, and omentoparietopexy may constitutes one of such methods.

[The small intestine intubation in the acute diseases of the abdominal cavity organs].

The prolonged small intestine intubation is one of the main methods of pathogenetic therapy of acute diseases of the gut, complicated by persistent and prolonged inhibition of its motor function. Securing the gut decompression, she promotes elimination of microcirculation disorders in it, as well as its morphological and functional restoration, permits to evacuate toxic content, provides enterosorption, dialysis and other treatment measures, stops the intraabdominal hypertension syndrome occurrence. Open small intestine intubation via appendico- or cecostomy aperture constitutes one of the methods of its performance. The variant of small intestine intubation performance proposed, using original conductor, makes the procedure more technically simple, permitting to escape complications. There was adduced the analysis of conduction of small intestine intubation in 51 patients.

[Helicobacter pylori prevalence among patients with gastroduodenal diseases in Kiev]. / Rasprostranennost' Helicobacter pylori sredi bol'nykh s zabolevaniiami gastroduodenal'noi zony v Kieve.

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.

[The application of laparocentesis and peritoneal lavage and the analysis of hemo-peritoneal volume in the diagnosis of closed abdominal wound]. / Primenenie laparotsenteza i peritoneal'nogo lavazha s opredeleniem ob''ema gemoperitoneuma v diagnostike zakrytoi travmy zhivota.

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.

[Osmotic homeostasis and radiosensitivity of NKLy lymphosarcoma cells]. / Osmoticheskii gomeostaz i radiochuvstvitel'nost' kletok limfosarkomy NKLy.

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.

[2-stage rupture of the spleen]. / Dvukhmomentnye razryvy selezenki.

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]. / Issledovanie énergeticheskikh parametrov membrany kletki Acetabularia

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.
