摘要
为研究参芎注射液对脑缺血再灌注老龄大鼠炎症损伤的影响。将84只SD大鼠随机分为假手术组、模型组、尼莫通组、参芎注射液高、中、低剂量组。连续腹腔注射给药3 d,采用线栓法建立大鼠脑缺血再灌注模型,再灌注24 h,神经功能评分,取脑TTC染色,ELISA法检测血清中肿瘤坏死因子-α(TNF-α)、白细胞介素-1β(IL-1β)的含量,荧光实时定量PCR(RTPCR)对海马区IL-1β,TNF-α,ICAM-1和MMP-9 m RNA的表达量进行检测。结果,参芎注射液可使脑梗死体积减少,明显改善神经功能,参芎注射液能减少IL-1β,TNF-α,ICAM-1和MMP-9 m RNA的表达量,并减少IL-1β和TNF-α的含量。表明参芎注射液对大鼠缺血再灌注损伤具有明显的保护作用,其机制可能与抑制炎症因子表达有关。
To investigate the effect of Shenxiong injection on the inflammation injury of ischemia-reperfusion injury senile rats. Totally 84 Sprague-Dawley (SD) rats were randomly divided into six groups: the sham operation group, the model group, the Nimodipine group and the Shenxiong injection(low, middle, and high dosage) groups. The rat cerebral ischemia-reperfusion model was established through intraperitoneal injection for 3 d and middle cerebral artery occlusion (MCAO). After the reperfusion for 24 h, efforts were made to give neurological score, collect brains for TTC staining, detect tumor necrosis factor-α(TNF-α) and interleukin-1β(IL-1β) content in serum by enzyme-linked immunosorbent assay (ELISA) method and measure IL-1β, ICAM-1 and MMP-9 mRNA expressions in hippocampal area by Real-time PCR (RT-PCR). According to the results, Shenxiong injection could decrease the cerebra[ infarction volume, greatly improved the neurological function and reduce IL-1β, TNF-α, ICAM-1 and MMP-9 mRNA expressions and IL-1β and TNF-α contents. In conclusion, Shenxiong injection shows the significant protective effect on ischemia-reperfusion injury in rats. Its mechanism may be related to the inhibition of inflammatory factor expression.
