The effect of sodium selenite on the enzymatic oxidation of retinal in vitro and vitamin A accumulation in the rat liver was examined. Selenium as sodium selenite at concentrations of 0.5--2.5 microgram/ml inhibited significantly (40--45%) the enzymatic irreversible oxidation of retinal. Dietary supplements of sodium selenite at a dose of 50--250 microgram/kg body weight caused an almost two-fold increase of the vitamin A content in the rat liver as compared with the controls that were given no selenium.
