[The effect of alimentary vitamin E on the seasonal fluctuations in the level of fluorescent lipopigments in the tissues of irradiated rats].

In seasonal experiments (spring and autumn) with Wistar female rats, a study was made of the level of lipopigments (LP) and alpha-tocopherol (TPh) fluorescence in the liver and brain. Seasonal peculiarities of the parameters under study and their dependence on Vitamin E ingestion have been revealed. After irradiation of animals, an intimate morphofunctional relationship between LP and TP and its sensitivity to alimentary factors have been found. One hour following irradiation, part of LP is disintegrated thus releasing the TPh reserve. This may be the part of the complex of adaptation changes on the postirradiation metabolic effects.
