摘要:

目的: 探讨龙血通络胶囊对大鼠脑缺血性损伤的保护作用。方法: 建立局灶性脑缺血模型,观察龙血通络胶囊对大鼠病理学改变的影响。建立局灶性脑缺血/再灌注模型,观察龙血通络胶囊对大鼠行为学改变的影响,并测定脑组织匀浆中谷胱甘肽过氧化物酶(GSH-Px)、超氧化物歧化酶(SOD)、乳酸脱氢酶(LDH)、丙二醛(MDA)、一氧化氮(NO)、诱导型一氧化氮合酶(iNOS)含量。结果: 与模型组比较,龙血通络胶囊高、中剂量组可改善行为障碍,降低行为学评分且降低脑组织含水量,同时龙血通络胶囊高、中剂量组可明显升高脑缺血模型脑组织中的SOD、GSH-Px、LDH的水平以及降低iNOS的活性和MDA、NO的含量。结论: 龙血通络胶囊对脑缺血性损伤有一定的保护作用,其作用机制可能与抑制脑组织中自由基损伤和iNOS含量有关。

Abstract:

AIM: To investigate the protective effects of Longxuetongluo capsule on cerebral ischemia injury in rats.  METHODS: The focal cerebral ischemia model was established to observe the extent of the pathological alteration and the focal cerebral ischemia reperfusion model was established to observe the change of behavior in rats. Meanwhile, the influence of Longxuetongluo capsule on the levels of Glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), lactate dehydrogenase (LDH), Malondialdehyde (MDA), NO and Induced nitric oxide synthase (iNOS) were investigated. RESULTS: Compared with model group, Longxuetongluo capsule of 0.66,0.33g/kg ameliorated neurologic deficits score and reduced the water content of brain tissue. In addition, Longxuetongluo capsule of 0.66 g/kg, 0.33g/kg can remarkly increased the levels of GSH-Px, SOD, LDH and decreased the activity of iNOS and the contents of NO and MDA. CONCLUSION: Longxuetongluo capsule has profective effects on cerebral ischemia injury and the mechanism maybe related to the resistance of free radical damage and the inhibiton of iNOS.

Key words: Longxuetongluo capsule, cerebral ischemia, SOD, NO, iNOS
