Effect of Fu-Sheng powder on NPY and its mRNA in brain of rats with hyperlipidemia after cerebral ischemia and reperfusion / 中国病理生理杂志

AIM: To observe the changes in neuropeptide Y(NPY) and the effect of Fu-Sheng powder(FSP) on NPY in the rat brain in a steady cerebral ischemia and reperfusion(I/R) model. METHODS: The models of rat brain injury were established by repeated cerebral I/R in rats with hyperlipidemia. Radioimmunoassay was performed to determine the level of NPY, while NPY mRNA expression was observed by in situ hybridization. RESULTS: After 1 day of I/R, compared with control group, the content of NPY in the model animals were significantly increased by 51.86% ( P
