Retinol deficiency and the activity of phospholipase A and some lysosomal enzymes in the testes of rats


, : Retinol deficiency and the activity of phospholipase A and some lysosomal enzymes in the testes of rats. Voprosy Pitaniya (3): 27-32

Phospholipases A1 (EC 3.1.1.32) and A2 (EC 3.1.1.4) were estimated, with some lysosomal enzymes in homogenates of testes of rats fed for 40 to 45 days on a vitamin A-deficient diet without and then for 40 days with retinyl acetate or retinoic acid. The delay in growth caused by the deficiency of vitamin A was corrected by the added retinol and retinoic acid. Retinoic acid caused adverse changes in macro- and microscopic structures and functions of the testes.
