The results showed that the blood LPO level increased significantly, and the activities of SOD and GSH-Px reduced significantly in patients of VD as compared with those in the control group. Degrees of patient’s condition were related with amplitudes of the increase of LPO and the reduction of activities of GSHPx and SOD. Combined treatment of acupuncture and moxibustion and Chinese drugs could raise markedly activitles of blood GSH-Px and SOD, and lowered LPO level in the patients of VD, which are related to clinical therapeutic effects. It is considered that combination of acupuncture and moxibustion with Chinese drugs can increase the action of the antiperoxidative system in the patients of VD, exerting anti-peroxidative ability and clearing LPO and reducing the oxidative injury of the organism by oxygen free radical, which is one of mechanisms of combined treatment of acupuncture and moxibustion with Chinese drugs.展开更多
目的探讨山奈酚(kaempferol,KAE)对慢性脑缺血大鼠的作用及其机制。方法采用双侧颈总动脉永久性结扎(bilateral common carotid arteries occlusion,2VO)建立大鼠慢性脑缺血动物模型;Morris水迷宫、抓握实验检测大鼠行为学;尼氏染色及H...目的探讨山奈酚(kaempferol,KAE)对慢性脑缺血大鼠的作用及其机制。方法采用双侧颈总动脉永久性结扎(bilateral common carotid arteries occlusion,2VO)建立大鼠慢性脑缺血动物模型;Morris水迷宫、抓握实验检测大鼠行为学;尼氏染色及HE染色观察脑组织病理改变;比色法检测MDA含量和SOD活性;Western blot检测脑组织DJ-1蛋白表达水平。结果与2-VO模型组比较,KAE明显改善慢性脑缺血诱导的学习记忆障碍和抓握能力损伤。此外,KAE明显减轻2VO大鼠脑组织病理损伤,增高脑组织中SOD活性,提高海马和皮层中抗氧化蛋白DJ-1的表达水平。结论KAE明显改善慢性脑缺血诱导的大鼠认知功能障碍、四肢平衡能力障碍及病理损伤,其机制可能与提高体内抗氧化系统有关。展开更多
目的探讨脑脉泰胶囊对血管性痴呆(VD)大鼠学习记忆能力以及脑脂质过氧化的影响。方法采用夹闭大鼠双侧颈总动脉20 m in,再灌10 m in,再夹闭20 m in的方式造成脑缺血-再灌注损伤模型,以Y型迷宫进行学习记忆能力测试,并测定脑组织超氧化...目的探讨脑脉泰胶囊对血管性痴呆(VD)大鼠学习记忆能力以及脑脂质过氧化的影响。方法采用夹闭大鼠双侧颈总动脉20 m in,再灌10 m in,再夹闭20 m in的方式造成脑缺血-再灌注损伤模型,以Y型迷宫进行学习记忆能力测试,并测定脑组织超氧化物歧化酶(SOD)、丙二醛(M DA)水平;采用颈内动脉注射凝血酶生理盐水溶液造成大鼠多发性脑梗死模型,以Y型迷宫进行学习记忆能力测试,并测定脑组织中伊文思蓝水平。结果脑脉泰胶囊能明显提高脑缺血-再灌注模型大鼠的学习记忆成绩(P<0.01),显著降低脑匀浆M DA水平(P<0.05、0.01),提高SOD活性(P<0.01);脑脉泰胶囊能明显提高多发性脑梗死模型大鼠的学习记忆成绩(P<0.05、0.01),降低脑组织伊文思蓝水平(P<0.01)。结论脑脉泰胶囊可改善VD大鼠学习记忆功能,减轻脑脂质过氧化损伤。展开更多
