[Systems analysis of the flow of associations in healthy subjects and patients with mental disorders].

By means of mathematical apparatus of a model of frequency lexical structure the structure of repetitions was studied in association flows of 10 healthy persons, 10 patients with sequelae of closed craniocerebral injury, and 10 schizophrenics. In comparison to healthy persons in those after the brain injury the number of repetitions was increased and the distances between the first and the last use of the repeated words were significant. In schizophrenic persons the repetitions of the words were situated at the local portions of association flows.

[A new method correcting metabolic acidosis].

A new method is suggested for correction of metabolic acidosis. The method consists in a decrease of pH of the bicarbonate sodium solution used for intravenous injection down to the physiological value of pH in the blood at the expense of buffering the solution by CO2. Experimental data conforming the efficiency of the new method application are presented.

[Possible mechanism of CO2 interaction with NAD-dependent malate dehydrogenase].

IR spectra of NAD-dependent malate dehydrogenase in the deuterium oxide solutions were studied in the absence of CO2 and at solution saturation with it. The presence of CO2 in the system results in weakening the absorption band intensity at 1650 cm-1 and in the appearance of the band at 1543 cm-1, which is explained by the formation of carbamates under conditions of the protein molecules free amino groups interaction with CO2.

[Compensatory reactions after surgical treatment of peptic ulcer].

The work is based on studies conducted in 30 experimental dogs with gastrointestinal ulcer induced experimentally, which were subjected to selective vagotomy with pyloroplasty after the Heinike--Mikulicz technic, and also in 22 patients having gastric ulcerous disease who were subjected to trunk or selective vagotomy with drainage operations or vagotomy associated with economic gastric resection. As a result of investigation performed, it was found that the operative intervention on the stomach i. e.

[Functional state of the liver in patients with malignant neoplasms, operated on with the use of ganglionic blockaders and moderate hypotension].

The functional state of the liver studied in 411 patients with malignant neoplasms undergoes the least variations under conditions of surgery with ganglionary blockade and moderate hypotension (not less than 90 mm Hg). These patients showed the best indices of protein metabolism and the status of the blood coagulation system, as well as activation of spontaneous anticoagulation. Complications in these patients were observed, but rather more rarely than in patients operated upon without using ganglionary blockade.
