摘要: 目的: 研究川芎嗪对辐射所致小鼠氧化损伤的预防和治疗作用。方法:采用60Co-γ射线5 Gy全身单次照射小鼠造模,分别于照射前(预防)和照射后(治疗)每天腹腔注射川芎嗪31.2 mg/kg,连续给药10 d,并设生理盐水阴性对照组,检测各组小鼠肝组织中丙二醛 (MDA)、超氧化物歧化酶 (SOD)、过氧化氢酶 (CAT)、还原型谷胱甘肽 (GSH)、谷胱甘肽过氧化物酶 (GPx)及总抗氧化力 (T-AOC)的变化。结果:与阴性对照组比较,60Co-γ射线照射可显著增加小鼠肝组织中MDA的含量 (P<0.05),降低SOD、GSH、GPx的活性 (P<0.05),使肝组织T-AOC下降 (P<0.05),但对CAT的活性无显著影响 (P>0.05)。与照射组比较,照射前和照射后给予川芎嗪,均可降低小鼠肝组织MDA含量 (P<0.05),使SOD、GSH、GPx的活性升高 (P<0.05)、肝组织T-AOC升高 (P<0.05),对CAT的活性仍无显著影响 (P>0.05)。结论:川芎嗪具有较好的抗氧化作用,预防和治疗性用药均可降低辐射所致小鼠的氧化应激损伤。

Abstract: OBJECTIVE: To study the preventive and therapeutic effect of ligustrazine against irradiation- induced oxidative stress. METHODS:Mice were exposed to 5 Gy single 60Co-γ irradiation to induce oxidative stress,the concentration of ligustrazine for daily intraperitoneal injection was 31.2 mg/kg to prevent and treat liver injury before and after irradiation. The injection lasted 10 days.We measured the parameters of malondialdehyde (MDA),superoxide dismutase enzyme (SOD),catalase (CAT),reduced glutathione (GSH),glutathione peroxidase (GPx),total antioxidation capability (T-AOC) activity in liver. RESULTS:Compared with negative control group,MDA was increased (P<0.05),the activities of SOD,GSH,GPx and T-AOC were decreased in the liver (P<0.05) after irradiation,while the activity of CAT was not changed significantly (P>0.05). By using ligustrazine,compared with irradiation group,MDA was decreased (P<0.05) and the activities of GSH,SOD,GPx,and T-AOC were increased significantly (P<0.05),whereas the activity of CAT was not changed significantly (P>0.05). CONCLUSION:Ligustrazine could reduce the oxidative injury induced by irradiation, either as prevention or treatment.
