Abstract
The inhibitory effect of selenium (Se) and change of glutathione perox idase activity during the development of brain tumors was investigated in Wistar rats. Four rat groups classified to match by age and weight were fed a diet containing 0, 0.5, 2.0, and 4.0 mu g Se/g. After 6 wk , the rats were injected with 3 x 10(6) Cg cells into the right fronta l lobe parenchyma. Survival was significantly longer in the 0.5 and 2. 0 mu g Se/g groups than in the Se-free and 4.0 mu g Se/g groups. The a ctivity of glutathione peroxidase after development of tumors was sign ificantly higher in the high Se group at 18 and 30 d.
