[The characteristics of the nigrostriatal brain system in genetic predisposition to catalepsy].

Activity of some enzymes of energy, protein and neurotransmitter metabolism in sensomotor cortex, caudate nucleus. S. nigra and N.

[Hemispheric asymmetry of the nigrostriatal system of the brain in rats genetically predisposed to catalepsy].

Hemispheric asymmetry of nigro-striate system in a strain of rats GC bred from Wistar for a predisposition to cataleptic reaction was studied by means of biochemical and morphological methods. Hemispheric asymmetry was found in GC and Wistar rats with respect to aminopeptidase activity in neurons of caudate nucleus, with a more pronounced left-side increase in GC rats, the asymmetry index being 13.7%.

[Morpho-chemical characteristics of the brain of rats genetically predisposed to catalepsy].

Cell organization of the cerebral cortex and striatum has been studied by+light optics and enzymatic activity of neuromediators catabolism--histochemically. In layers III and V of the sensomotor cortex and in the nucleus caudatus the number of neurons per unit area is increased, and their size is decreased. Volume of cytoplasm and nuclei of neurons in both layers is decreased, the latter--to less extent.

[Precancerous conditions of the stomach in inhabitants of the Kalmyk ASSR].

A study involving the use of acidity test of gastric secretion in healthy population living in the four areas of the Kalmyk ASSR characterized by different natural conditions and different rates of stomach cancer incidence established a correlation between a higher frequency of this disease, on the one hand, and enhanced rates of anacidity as well as higher salinity of soil and water, on the other.
