ABSTRACT

Objective To observe the antioxidative dosage-effect relationship of grape seed proanthocyanidin extract (GSPE). Methods The mice were randomly divided into seven groups:blank group, model group, 5 mg/kg GSPE group, 15 mg/kg GSPE group, 45 mg/kg GSPE group, 135 mg/kg GSPE group and 405 mg/kg GSPE group. The mice in blank group were dealt with saline solution by intraperitoneal injection, the others were dealt with D-galactose (120 mg/kg) by intraperitoneal injection for seven weeks to make oxidative damage model. Meanwhile, the mice were given corresponding dose of the drug. Subsequently the level of malondialdehyde (MDA) and activity of superoxide dismutase (SOD) in the serum were measured to observe the antioxidative dosage-effect relationship of GSPE. Results The 45, 135, 405 mg/kg GSPE group reduced the MDA level, and the 15, 45, 135, 405 mg/kg GSPE group increased the SOD activity. Conclusion GSPE has significant antioxidant activity on mice dealt with D-galactose above the dose of 15 mg/kg, suggesting that the clinical use of GSPE should guarantee a certain dose to play a good antioxidant effect.

ABSTRACT

Objective To observe the antioxidative dosage-effect relationship of Marigold lutein, and provide experimental data for clinical use. Methods The mice were randomly divided into seven groups:blank control group, model control group, 1 mg/kg lutein group, 5 mg/kg lutein group, 25 mg/kg lutein group, 125 mg/kg lutein group and 625 mg/kg lutein group. The mice in blank control group were dealt with saline solution by intraperitoneal injection, the others were dealt with D-galactose (120 mg/kg) by intraperitoneal injection for seven weeks to make oxidative damage model, meanwhile the mice were given corresponding dose of the drug. Subsequently, the level of malondialdehyde (MDA) and activity of superoxide dismutase (SOD) in the serum were measured, and the antioxidative dosage-effect relationship was observed. Results The 1, 5, 25 mg/kg lutein reduced the MDA level and increased SOD activity, and the 125, 625 mg/kg dose of lutein did not show significant antioxidant activity. Conclusion Lutein has significant antioxidant activity in mouse dealt with D-galactose within the dose range of 1-25 mg/kg. The results suggest that the clinical dosage range of lutein should be kept within reasonable limits.
