摘要：
The effect of alpha -tocopherol on cell proliferation and proliferated cell survival was investigated in the dentate gyrus of adult rats. Adult rats were supplemented with alpha -tocopherol, injected with 5-bromo-2'-deoxyuridine (BrdU), that is incorporated into DNA during the S-phase, and killed at different time after BrdU injection. The number of newborn cells decreased after alpha -tocopherol supplementation, confirming the hypothesis that alpha -tocopherol is able to depress cell proliferation in vivo. Most newborn cells die within few days; more newborn cells survive in alpha -tocopherol-treated rats, suggesting the hypothesis that alpha -tocopherol decreases cell death.
