In hiperlipidaemia both in men and in animals an observed increase in activity of acylcholine acylhydrolase is explained by a substrate induction or by a „metabolic stress” resulting from a diet used. Because of hypolipemizing and anti-stress action of vitamin C their content and influence on activity of acylcholine acylhydrolase (ChE), content of a total protein (Pr), fat (TL) and cholesterol (TCh) in blood plasma of three groups of cocks (K-control; T — cholesterol-fat diet; TC — cholesterol-fat diet enriched with vitamiic C (0.5 g) was examined. It was found that: 1) in group T and TC increased significantly (p ≤ 0.01) in comparison to group K values of ChE, TL, TCh and Pr, 2) in group TC increased significantly (p ≤ 0.01) the content of vitamin C in comparison to group K and T, significantly decreased ChE a proper activity of -ChE-w (p ≤ 0.01) TCh (p ≤ 0.05) and non significantly changed TL in comparison to group T. It may be assumed that vitamin C depresses reactions of an organism induced by a diet. Therefore, it is probable that in metabolic disorders resulting from overloading of cocks with a fat diet enrichement of food with vitamin C is profitable.
