title: [Anti-oxidative effects of proanthocyanidins in mice induced by D-galactose].
abstract: The anti-oxidative effect of proanthocyanidins(PC) was evaluated in D-galactose-induced murine model. Male KUNMING mice were divided into different groups at random. The mice were induced by subcutaneous injection of D-galactose on the back of mice daily for 60 days and simultaneously PC and VE were administered to the mice by oral feeding. Results indicate that the lipid peroxide in blood, liver and brain significantly increased respectively because of the D-galactose injection, when compared to the control. The activity of SOD in RBC and liver significantly decreased while that of GSH-PX in blood and liver decreased. MAO-B in brain was significantly increased while MAO-B in liver doesn't change significantly. Oral feeding PC markedly decreased the formation of MDA in blood, liver and brain, increased the activities of SOD in blood and liver and decreased the activity of MAO-B in brain. Vitamin E also counteract the oxidative stress induced by D-galactose. In summary, treatment with PC at all the three tested doses were effective in exerting a protective effect against oxidative stress.
