[Efficiency of an arbitrary respiratory rhythm reducing method in students of special medical physical educational groups].

Three-month decreased voluntary optimum respiration rate (DVORR) trainings during therapeutic exercises in students with various abnormalities caused increases in vital capacity and chest circumference amplitude. DVORR also affected cardiovascular performance. During exercises, heart rate decreased and pulse pressure increased, suggesting economized cardiac performance and better myocardial function.

[Effects of adrenergic substances on the cardiac rhythm and electrical activity of the brain in rabbits during hypoxia].

The paper reports the effects of alpha and beta-adrenergic substances on the cardiac rhythm and electrical activity of the brain under the hypoxic conditions. beta-adrenergic substances were shown to have a stronger influence on these parameters as compared with alpha-adrenergic. The neoepinephrine effects were pronounced before "lifting", while the propranolol effects increased "at the altitude".

[Role of the amygdaloid complex of the brain in the regulation of blood coagulation].

The response of biochemical parameters of coagulation to chemical stimulation of different amygdaloid structures has been studied. It is demonstrated that a microinjection of L-glutamate, a stimulating amino acid, into the above structures induces hypercoagulation. This gives evidence for a direct implication of the amygdala, an essential structure of the limbic system, in the mechanisms controlling central regulation of blood coagulation with probable involvement of direct amygdalospinal tracts.
