摘要:
背景: 如今,肝缺血再灌注(HI/R)损伤被认为是临床实践中的严重关注。 Huperzine A (HupA) is an alkaloid isolated from the Chinese folk medicine huperzia serrate, which has possessed diverse pharmacological actions.
METHODS: A mouse model of HI/R was caused by clamping the hepatic artery, the hepatoportal vein, and the bile duct with血管夹30分钟,然后在麻醉下再灌注6小时。假小组经历了我无肝缺血的牙科手术。 HUPA组以167和500μg/kg的剂量在HI/R前5分钟注射到尾静脉。将车辆组注入生理盐水,而不是HUPA。通过测定丙氨酸氨基转移酶(ALT)和天冬氨酸氨基转移酶(AST)活性来评估肝功能。分光光度法测量了超氧化物歧化酶(SOD),过氧化氢酶(CAT),丙二醛(MDA)和谷胱甘肽(GSH)的组织水平。此外,还测量了肝炎症介质(例如核因子Kappa B(NF-κB)p65,肿瘤坏死因子-α(TNF-α,Iltleukin-1β(IL-1β)和IL-6)的活性。此外,还测量了结果: 在小鼠中以167和500μg/kg的剂量用hupa治疗的hupa治疗中的血清ALT和AST AST活性降低了化学小鼠。此外,HUPA治疗可以增强肝组织SOD,CAT和GSH的活性,但会降低MDA组织含量。在用HUPA处理的缺血小鼠中,包括NF-κBp65,TNF-α,IL-1β和IL-6在内的炎性细胞因子的活性都降低了。 Colorimetric test results illustrated that a marked reduction of caspase-3 activity was found in the HupA-treated group compared with the vehicle group.
CONCLUSION: Our present data suggest that HupA has a protective role against HI/R injury of mice and antioxidative, anti-inflammatory, and antiapoptotic动作涉及其保护。
