Abstract:

To investigate the antioxidant effects of the Cordyceps militaris polysaccharides(CMP),90 male BALB/c mice were randomly divided into six groups, three experimental groups (CMP groups), model control group (CY group), blank control group (BC group) and positive control group (PC group). The mice in CMP and CY groups were given cyclophosphamide at 80 mg/kg via intraperitoneal injection for 3 d. Then the CMP groups were administrated 17.5, 35.0 and 70.0 mg/(kg·BW) CMP via gavage, respectively, BC and CY groups were given physiological saline, and PC group was orally administered 70 mg/(kg·BW) CMP, lasting 18 d. At 24 h after the last administration, heart, liver and kidney were collected to measure the levels of MAD, CAT, SOD, GSH-Px and T-AOC in the homogenate.SOD and TAOC activity of three CMP groups increased significantly (P<0.01), and the level of MDA decreased significantly (P<0.01) compared with CY group. As for CAT activity of heart, the value in low-dose CMP group had no significant change (P>0.05), while in middle and high-dose groups had significant (P<0.05) and extremely significant(P<0.01) increase respectively. Except that the hepatic GSH-Px activity increased significantly (P<0.05) in low-dose CMP group, the rest values of GSH-Px activities in all CMP groups increased extremely significantly (P<0.01). The results indicated that CMP could effectively improve the antioxidant function of mice and had the potential to be a good resource of new antioxidant drugs.
