摘要: 探讨黑果枸杞水提取液对辐射损伤小鼠的保护作用。除正常对照组外各组小鼠接受5Gy的X射线一次性全身均匀照射。检查各组小鼠外周血中红细胞数(RBC)、白细胞数(WBC)、血小板数(PLT)、血红蛋白数(HGB),计算胸腺和脾脏指数,测定抗氧化酶活力、DNA和Caspase-3、Caspase-6的含量。黑果枸杞水提取液对辐射后小鼠的血象有明显回升,SOD活力明显增强,DNA含量增多,CAT、GSH-PX、T-AOC活力下降,Caspase-3和Caspase-6的含量降低,脏器指数无统计学意义。研究结果显示,黑果枸杞水提取液对X射线所致小鼠辐射损伤有一定保护作用。

Abstract: To study the protective effects of Lycium ruthenicum Murr extract against radiation-induced damage on mice.Except the normal control group,mice of other groups were received with 5 Gy of X-radiation.Red blood cell count (RBC),white blood cell count (WBC),platelet count (PLT),hemoglobin count (HGB),thymus index and spleen index,activity of various antioxidant enzymes,DNA and caspase-3,caspase-6 content were observed at 7 d after radiation.The results showed that L.ruthenicum extract significantly increased quantity of hemogram,activity of SOD,content of DNA in bone marrow.The activity of CAT,GSH-PX,T-AOC and the content of caspase-3,caspase-6 significantly reduced.In addition,the spleen index,thymus index had no statistical significance in our study.These results indicated that L.ruthenicum had protective effects on mice radiation damage.

Key words: Lycium ruthenicum Murr, anti-radiation, scavenging free radicals, antioxidant activity
