摘要:

目的:观察复方当归注射液(CAI)对局灶性脑缺血损伤模型大鼠患侧脑组织及血清中脑源性神经营养因子(BDNF)表达水平的影响,探讨CAI对脑缺血损伤的作用机制。方法:50只SD大鼠随机分为假手术组(10只)和局灶性脑缺血损伤组(40只)。局灶性脑缺血损伤组采用线栓法复制大鼠局灶性脑缺血损伤模型,将造模成功的30只大鼠随机分为模型组、CAI组和阳性对照依达拉奉组,每组10只。造模大鼠苏醒后进行神经功能评分,7 d后取材,HE染色检测大鼠脑组织的病理学改变,测定大鼠血清及缺血侧脑组织中BDNF的表达水平。结果:与假手术组比较,模型组大鼠神经功能评分增加(P<0.05),大鼠神经细胞出现肿胀、坏死和细胞间质水肿等改变,缺血侧脑组织及血清中BDNF表达水平有一定的上升趋势;CAI组大鼠缺血侧脑组织BDNF表达水平显著升高(P<0.05),血清BDNF表达水平有所升高。与模型组比较,CAI组大鼠神经功能评分降低,大鼠神经细胞轻微水肿,缺血侧脑组织及血清BDNF表达水平有所升高。结论:CAI可能具有提高脑内BDNF表达的作用,其作用机制可能与机体在缺血损伤情况下脑内相应的神经因子做出应激反应有关。

Abstract:

Objective To investigate the effect of Compound Angelica Injection (CAI) on the expressions of brain derived neurotrophic factor (BDNF) in brain tissue and serum in the rats with cerebral ischemia injury, and to explore the related mechanism of effect of CAI on cerebral ischemia injury. Methods 50 SD rats were randomly divided into sham operation group (n=10) and cerebral ischemia injury group (n=40), and the rats in cerebral ischemia injury group were reproduced by middle cerebral artery occlusion (MCAO). Thirty successfully modeling rats were randomly divided into model group, CAI group and edaravone group (n=10). The neurologic scores of the rats after waking up were measured. The pathomorphology of brain tissue of the rats was detected by HE staining 7 d later. The levels of BDNF in the brain tissue and serum of the rats were detected. Results Compared with sham operation group, the neurologic score of the rats in model group was increased (P<0.05); the neurocytes of rats were changed to swell, necrosis, and interstitial edema; the levels of BDNF in brain tissue and serum showed a tendency of increasing; the level of BDNF in brain tissue of the rats in CAI group was increased significantly (P<0.05), and the serum BDNF level was a little higher. Compared with model group, the neurologic score of the rats in CAI group was decreased (P<0.05); the neurocytes of rats were mild edema; the levels of BDNF in brain tissue and serum showed a tendency of increasing. Conclusion CAI may has a positive function in increasing BDNF expression,and the mechanism may be related to the stress reaction of corresponding neural factors in brain tissue under ischemia injury condition.
