[Supposed role of "metabolic memory" in formation of response reaction to stress-factors in young and adult organisms].

The influence of the combined long-lasted influences of sulfur sulfate and diet restriction in young (3 month age) and adult (21 month age) Vistar rats on activity of glucose-6-phospatase, alaninaminotranspherase (ALT), aspartataminotranspherase (AST), and on phosphorilating activity of liver mitochondria was studied to investigate the role of metabolic memory on the peculiarities of response reaction. The young animals not differed from adult ones in the possibility of inducing activity of glucose-6-phospatase, ALT, and on phosphorilating activity after the influence of sulfur sulfate and diet restriction. The age-related differences in glucose-6-phospatase and transpherases and phosphorilating activity existing in control disappeared after the long-lasted action of sulfur sulfate and diet restriction.

[The growth constraining diet causes various strategy of adaptation in young and adult animals].

The glucose-6-phosphatase activity of microsomes and phosphorylative mitochondrial activity of liver cells, alanine- and aspartate aminotransferase activities in plasma of blood of young (3 month) and adult (21 month) male rats kept under three various diets resulting in a various degree of a growth inhibition and losses of weight of a body have been studied. There were selected diets giving to animals the food full-valued by composition but limited by quantity. Experiment proceeded 50 days.
