Influence of triptolide on neuronal apoptosis in rat with cerebral injury after focal ischemia reperfusion by Deng-ming Wei, Guang-zhao Huang, Yi-gu Zhang, Guang-xun Rao.
Objective: To study effect of triptolide(TL) on neuronal apoptosis in cerebral tissue rat after ischemia-reperfusion. Method: Triptolide at dose 0.2 or 0.4 mg·kg -1was intr aperitoneally injected once a day for 4 d. The focal ischemia-rep erfusion model was established with thread embolism middle artery before trip tolide injection the fourth day. Neurological deficit score rats eval uated; and immunohistochemical techniques were used to count positive cells express MPO TUNEL tissue. Result: Compare d control group, neural function significantly impr oved, number infiltrate neutrophil cere bral remarkably reduced two TL-treated groups. Conclusio n: results suggested that TL can inhibit infiltration decrease degree [
