群多普利对大鼠脑缺血再灌注损伤的保护作用研究 Neuroprotective Effects of Trandolapril on Rat Cerebral Ischemia-reperfusion Injury
目的 观察群多普利对大鼠局灶性脑缺血损伤的保护作用,并探究其可能作用机制。 方法 采用改良ZeaLonga's法制作大脑中动脉闭塞(middle c erebral a rtery o cclusion,MCAO)模型。将 健康雄性SD大鼠随机分成假手术组、模型组、群多普利低剂量组(5 mg/kg)、群多普利高剂量组 (10 mg/kg)等四组,观察各实验组大鼠神经功能评分、脑梗死体积、脑组织白细胞介素(i nterl euki n, IL)-1β及IL-10含量变化。 结果 与假手术相比,模型组神经功能缺损程度评分显著提高,脑组织IL-1β及IL-10含量显著增加 (P<0.05)...

Abstract:
Objective To investigate the neuroprotective effect of Trandolapril on cerebral ischemiareperfusion injury, and explore its possible mechanism. Methods The model of focal ischemic reperfusion in Sprague-dawley (SD) rats was prepared by middle cerebral artery occlusion (MACO) with a nylon monofilament suture. Adult male SD rats were divided randomly into sham operation group, model group, and Trandolapril treatment groups (low dosage 5 mg/kg, high dosage 10 mg/kg). The changes of neurological function scores, the cerebral infarction volumes, interleukin (IL)-1β and IL-10 content in the brain were observed. Results Compared with the sham group, integrals of neurologic defect degree, infarction volume and the IL-1β and IL-10 content in the brain of the model group were significant increased (P <0.05). Compared with the model group, treatment with Trandolapril (5 mg/kg and 10 mg/kg) lowered the integrals of neurologic defect degree and reduced the cerebral infarction volumes. Trandolapril (5 mg/kg and 10 mg/kg) could significantly reduce the content of IL-1β (P <0.05), and Trandolapril (10 mg/kg) could significantly increase the content of IL-10. Conclusion Trandolapril could alleviate cerebral ischemia reperfusion injury by regulating the expression of the pro-inflammatory IL-1β and anti-inflammatory IL-10 cytokines. |
