title: [Age and characteristics of cholesterol biosynthesis in rat liver under normal conditions and during atherogenic loading].
abstract: Intraperitoneal injection of C14CH3COONa to normal rats aged 6--8 and 28--32 months revealed a slower dynamics of cholesterol biosynthesis in the liver of old rats at the maximum of the tracer incorporation was lower than in the young ones. Atherogenic diet (0.25 g of cholesterol per 100 g of animal weight for a period of 20 days) was accompanied by an increase in the total cholesterol content and depressio of its biosynthesis in the liver, more pronounced in the young rats. Continued cholesterol administration caused further depression of its biosynthesis, most pronounced (in this case) in the old animals.
