目的：观察银杏外种皮多糖（ＧＢＥＰ）对不同状态小鼠血清ＳＯＤ和ＭＤＡ形成的影响。方法：用ＧＢＥＰ给荷瘤小鼠、环磷酰胺（ＣＴＸ）抑制小鼠及正常小鼠灌胃给药，检测小鼠血清中的ＳＯＤ活性及ＭＤＡ含量。结果：ＧＢＥＰ可明显提高荷瘤小鼠血清ＳＯＤ活性，并能降低其ＭＤＡ含量，也能改善ＣＴＸ抑制小鼠的上述指标，但对正常小鼠则无明显影响。结论：ＧＢＥＰ可促进机体在病理状态下的自由基清除能力。
Objective: To observe the effect of Ginkgo biloba exocarp polysaccharide (GBEP) on serum SOD and MDA formation in mice with different states. Methods: The tumor-bearing mice, cyclophosphamide (CTX)-inhibitory mice and normal mice were intragastrically administered with GBEP and the serum SOD activity and MDA content were detected. RESULTS: GBEP significantly increased the serum SOD activity in tumor-bearing mice and reduced its MDA content. It also improved the CTX-inhibitory effect in mice, but it had no significant effect on normal mice. Conclusion: GBEP can promote the body’s free radical scavenging ability under pathological conditions.
