[An assessment of the manifestation of the functional connections between brain structures]. / Otsenka vyrazhennosti funktsional'nykh sviazei mezhdu strukturami golovnogo mozga.

Responses of hypothalamic neurons to single (1/s, 20 impulses) stimulation of the prefrontal (area 8), cingulum (area 24), periamygdaloideus (RPA) cortex and hippocampus (field CA3) were studied on experimental cats anesthetized with ketamine. The routine elaborated for IBM PC/AT 386 provided: 1) selection of such neurone reaction with the latent period variation less than its length per the set value (5-20%); 2) selection of repeated neurone reactions with the same variability of latent periods from 20 cortical stimuli; 3) ranging of neurone reactions according to these indices. Quantitative estimation of the priority ranges made it possible to determine the profundity of the functional relations between the cerebral structures.

[Assessment of the erythropoietin-producing function of the kidney and liver under controlled perfusion]. / Otsenka éritropoétinprodutsiruiushchei funktsii pochki i pecheni v usloviiakh upravliaemoi perfuzii.

The balance of erythropoietin production by the dog kidney and liver was studied during controlled normoxic perfusion. The hormone production was stimulated by acute posthemorrhagic anemia (bloodletting of 25% total blood volume) combined with subcutaneous injection of cobaltous chloride (250 microM/kg body weight). The increase in erythropoietin level was revealed in posthypoxic animal perfusate after 6 hours of perfusion. The amount of hepatic erythropoietin was shown to be 2.5 times higher than that excreted by kidneys.
