Abstract:
Objective To investigate the effect of Huangjiao granule on inflammatory factors and apoptosis-related proteins in rats with cerebral ischemia-reperfusion injury.Methods A total of 40 Sprague-Dawley rats were divided into sham operation group, model group and Huangjiao granule group, with ten rats in each group, and ten rats standby. The cerebral ischemia for two hours and reperfusion model was established by suture method. The sham operation group and the model group were given saline 10 ml/kg intragastrically 30 minutes before operation. The Huangjiao granule group was given Huangjiao granule solution 10 ml/kg (the content of crude drug was 1 g/ml) intragastrically 30 minutes before ischemia-reperfusion. Longa scoring method was used to evaluate the neurological function score 24 hours after reperfusion, while the percentage of cerebral infarction volume was detected by TTC staining, the pathological morphology of brain tissue was observed by HE staining, the cell apoptosis of brain tissue was detected with TUNEL, the levels of interleukin (IL)-1β, IL-6 and tumor necrosis factor α (TNF-α) in serum were detected by ELISA, the expression of cleaved-caspase 3, cleaved-caspase 9, Bax and Bcl-2 proteins of brain tissue was evaluated by Western blotting.Results Compared with the model group, the neurological score decreased, the percentage of cerebral infarction volume and the apoptosis rate of the brain tissue decreased in Huangjiao granule group (P<0.05). The levels of IL-1β, IL-6 and TNF-α in serum and the expression of cleaved-caspase 3, cleaved-caspase 9 and Bax proteins of brain tissues significantly decreased (P<0.05), and the expression of Bcl-2 protein of brain tissues inreased in Huangjiao granule group (P<0.05).Conclusion The protective effect of Huangjiao granule on rats with cerebral ischemia-reperfusion injury may be related to the inhibition of inflammatory response and the reduction of apoptosis.
