[Effect of diet on the lipid composition of cell nuclei and liver mitochondria during ontogenesis of the rat].

The possible influence of the type of dietary fat on quantitative changes of different lipids in microsomes, nuclei and chromatin in hepatic cells of albino rats in ontogenesis was studied. While the type of diet had no significant influence on the levels of different phospholipids and fatty acids of nuclei, the type of dietary fat exerted definite effect on the levels of whole phospholipids, cholesterol of microsomes, nuclei and fatty acids of chromatin. The age specificity was observed in nuclear structures.
