[Controlled heparinization during hemosorption].

The authors used a method of graded heparinization with special reference to the individual reaction of the patients to heparin. The initial (starting) dose of heparin was injected intravenously, the sustaining dose of heparin was infused through the tube for blood taking. The method described prevented thrombosis of the HMS apparatus and considerably reduced the quantity of heparin used. No complications of hemosorption resulting from heparinization were noted.

[Concentration of free fatty acids in muscle following administration of corticotropin and hydrocortisone].

Experiments were conducted on rats; the gas chromatographic method was applied to the study of the free fatty acids content in the gastrocnemius 30 minutes after the intraperitoneal injection of adrenocorticotropic hormone (ACTH)--1 Unit per 100 g and hydrocortisone acetate--1 mg per 100 gm of body weight. It was shown that in the resting muscles ACTH increased the content of stearic acid, whereas hydrocortisone--of both stearic oleic acids. The changes in the content of other free fatty acids were insignificant. During the short-term activity the content of stearic acid in the regimen of single rhythmic contractions in the gastrocnemius of intact rats increased. In experiments with ACTH and hydrocortisone this elevation was much less and not significant. ACTH and hydrocortisone stimulated the stearic acid consumption by the muscles during the activity.

[Importance of the step test for the evaluation of the functional state of the cardiovascular system].

Cardiovascular reactions of 100 healthy cadets (1st group) and 45 persons with clinical signs of autonomic-vascular dystonia of the cardiac type (2nd group) to submaximal exercises (Harvard step-test of 1800--21000 kgm/min for 5 min with a total workload of 9000--10500 kgm) were investigated. The cardiovascular function was estimated with respect to electrocardiography, polycardiography, carotid artery sphygmography and left ventricular cardiography. After the step-test the 2nd group test subjects showed distinct changes--hypoxia, arrhythmias, disorders in the phase structure of the systole and diastole--which pointed to a decrease of reserve capabilities and resistance of the cardiovascular system.
