[Phospholipid composition of membrane lipids of hepatic subcellular structures in rats under the effects of different nutrition and phosphorus and fluorine compounds].

A study was made of the phospholipid composition of the membranes of the rat liver nucleus, mitochondria and microsomes under the effect of different nutrition, hydrogen fluoride and phosphine. It was established that prolonged exposure to hydrogen fluoride and phosphine resulted in alterations of the phospholipid composition of the membranes of the liver nucleus, mitochondria and microsomes. The pattern of nutrition, the diet content of retinol, tocopherol, ascorbic acid and essential amino acids (lysine, methionine, threonine) determined not only the quantitative and qualitative composition of phospholipids but also the action of the foreign substances under study on the cell membranes. The enrichment of the diet with retinol, tocopherol, ascorbic acid and thiamine reduced the membrane-damaging action of hydrogen fluoride and phosphine.
