摘要: 目的: 比较银杏叶提取物制剂(ginkgo bilobo extract, EGB) 舒血宁及银杏达莫对老龄大鼠血浆超 (过) 氧化物歧化酶(SOD) 、丙二醛(MDA) 、一氧化氮 (NO) 含量及血液流变学的影响。 方法: 24 只老龄 大鼠随机分为 4 组:对照组、银杏达莫组 、舒血宁组 和双嘧达莫组, 分别给予生理盐水、银杏达莫、舒血 宁和双嘧达莫, 各组动物分别腹腔注射相应药物, 给 药容量均 2 ml·kg-1, 每日 1 次, 连续用药 7 d。另 6 只正常大鼠作为正常对照。 测定血液流变学指标及 血浆 SOD、MDA、NO 的含量。结果: 银杏达莫组与对 照组相比, 血浆 SOD 显著升高(P<0.05), MDA 含 量显著降低(P<0.01), 全血粘度值(高切) 和纤维 蛋白原含量明显降低(P<0.05);舒血宁组与对照 组相比, 血浆SOD显著升高(P<0.05), 全血粘度值 (高切) 、全血粘度值(低切) 和纤维蛋白原含量等均 明显降低(P<0.05);双嘧达莫组与对照组相比, 纤 维蛋白原明显降低(P<0.01), 红细胞变形指数明 显升高(P<0.05), 血浆 SOD 和 MDA 含量虽有改 变, 但差异均无统计学意义;各用药组血浆 NO 含量均降低, 但无统计学意义。银杏达莫组与舒血宁组 相比, 对老年大鼠血液流变学指标及血浆 SOD, MDA 和NO 含量的影响无明显差别(P >0.05)。 结论: 舒 血宁、银杏达莫对老年大鼠血液流变学指标均有改 善作用, 并升高老年大鼠血浆 SOD, 降低 MDA 的含量, 提示两药均具有抗衰老, 抗氧化, 扩张冠脉血管、 脑血管, 改善脑缺血症状的作用。

Abstract: AIM: To compare Yinxingdamo injection with Shuxuening injection on hemorheology and plasma levels of superoxide dismutase (SOD), malondialdehyde (MDA) and nitrogen monoxidum (NO) in aged rats. METHODS: 24 aged rats were randomly divided into 4 groups:control, Yinxingdamo group, Shuxuening group and dipyridamole group.The ratswere givenNS, Yinxing-damo injection, Shuxuening injection and dipyridamole, respectively.The administration dosages were 2 ml·kg-1, once everyday for 7 d successively.Another six normal young rats were arrayed into normal control.Hemorheolo-gy and plasma levels of SOD, MDA and NO were mea-sured.RESULTS: After intraperitoneal injection of Yinxingdamo for 7 days, the level of SOD in plasma of aged rats increased (P<0.05) and the level of MDA de-creased (P<0.01), the whole blood viscosity (at high shear rate) and contents of fibrinogen decreased (P<0.05) compared with those of control group.The level of SOD in plasma of aged rats increased obviously (P<0.05), the whole blood viscosity (at high or lower shear rate) and content of fibrinogen decreased (P<0.05) in Shuxuening group compared with those in control group. After intraperitoneal injection of dipyridamole injection, content of fibrinogen decreased (P<0.01) and index of red blood cell deformation increased (P<0.05) com-pared with those of control group.Plasma NO contents showed a tendency to decrease, but there was no signifi-cant statistical difference between either two groups. There was also no obvious difference on hemorheology and levels of SOD, MDA andNO in plasma between Yinxing-damo group and Shuxuening group (P >0.05).CONCLUSION: Changes of hemorheology in aged rats can be improved with Yinxingdamo or Shuxuening, the level of SOD increases and the level of MDA decreases.The re-sults suggest that the two drugs have effects of anti-aging, anti-oxidation, dilating coronary vessels and cerebral ves-sels and improving the symptom of cerebral ischemia, which may be the pharmacological foundation of prevent-ing and treating high-incidence diseases among aged peo-ple of these two drugs.
