摘要: 目的 研究三七总皂甙(PNS)对大鼠局灶性脑缺血的保护作用。方法 阻断大鼠大 脑中脉造成可逆性脑缺血模型,观察PNS对缺血脑组织的保护作用。结果 PNS 20、40 mg·kg-1·d-1x10d能显著改善大鼠MCAO后的神经功能障碍,缩小脑梗塞面积,减轻脑水肿,并能降低缺血脑组织的总钙含量,明显提高SOD活力,降低MDA含量。结论 PNS对局灶性缺血脑组织具有保护作用,其机理推测与降低脑组织钙含量及抗氧自由基损伤有关。

Abstract: Aim To study the protective effects of punax notojinseg (PNS) on local cerebral ischemia in rats. Methods Local cerebral ischemia in rats was induced by occlusion of the middle cerebral artery (MCAO) without craniectomy.Results PNS in the doses of 200 and 400 mg·k-1·d-1x 10 d significantly decreased the infarct size and brain edema and ameliorated neurologic deficits in rats subjected to MCAO for 2 or 24 hours. The same dosage of PNS could markedly increase the activity of superoxide dismutase (SOD) and decrease the concentration of malondialdehyde (MDA) and Ca2+ in the brain.Conclusions Declining free radicals and decreasing Ca2+ content in brain might be one of the important factors involved in the anti-cerebral ischemia effect of PNS.
