[Influence of prenatal and postnatal illumination on male rat physiologycal parameters]

Influence of different light conditions on some physiological parameters of 3-month old male rats was studied. It was established that influence of constant light on mothers during pregnancy or on their posterity from birth leads to one-way changes of the antioxidant system, isoenzymatic spectrum of lactate dehydrogenase, blood indices and leucogram. However, the reaction is different and depends on moment of exposure. The results of testicular development of male rat indicate less sensitivity to light condition in the prenatal period compared to the postnatal ontogenesis.
