Abstract:

Objective To investigate the effect of Xing-naojing and Shengmai injection on protease activated receptor-1(PAR1) expression in rat brain tissue after intracerebral hemorrhage (ICH).Methods  The ICH model was induced by injecting blood of its own. Forty male SD rats were randomly divided into ICH group (n=10), saline group (NS, n=10), Xing-naojing and Shengmai injection group (XNJSM, n=10), hirudin group (HIR, n=10). Hematoxylin and eosin staining was performed to examine perihematomal neurocyte morphological changes. The expression of PAR1 in perihematomal tissue was examined by immunohistochemistry and Western blotting techniques. Results The expression of PAR1 in perihematomal tissue was increased after ICH. However,compared with ICH group, perihematomal tissue morphological changes were improved obviously. The expression of PAR1 was decreased significantly between XNJSM group and HIR group(P<0.05). Conclusion  XNJSM injection may play a neuroprotective effect by inhibiting the expression of PAR1 protein after ICH.
