摘要
目的:通过检测脑组织内丙二醛(MDA)、超氧化物歧化酶(SOD)含量和谷胱甘肽过氧化物酶(GSH-Px)活性,探讨亚低温、川芎嗪对缺氧缺血性脑病幼鼠的脑保护作用。方法:将142只大鼠幼鼠随机分为常温缺血组(A组)、常温缺血+亚低温组(B组)、常温缺血+川芎嗪组(C组)、常温缺血+亚低温+川芎嗪组(D组),建立缺氧缺血性脑病幼鼠模型,各组给予相应的治疗,检测各组幼鼠脑组织内MDA、SOD含量及GSH-Px活性,对结果进行比较和统计分析。结果:B组、C组、D组幼鼠MDA含量均较A组低,SOD含量及GSH-Px活性高于A组,提示亚低温和川芎嗪治疗缺氧缺血性脑病有效;D组脑组织内MDA含量较B组、C组低,SOD含量、GSH-Px活性较B组、C组高,差异有统计学意义(P均<0.01)。B、C两组MDA和SOD含量及GSH-Px活性比较差异无统计学意义(P>0.05)。结论:亚低温、川芎嗪均能减轻缺氧缺血引起的脑损伤,二者联用疗效更佳。
Objective:To research the cerebral protective effects of mild hypothermia and ligustrazine by detecting the MDA, SOD levels and GSH-Px activity of brain tissues in young rats with hypoxic ischemic encephalopathy. Methods: Totally 142 young rats were randomly divided into four groups, group A, ormal temperature and ischemia; group B, normal temperature and mild hypothermia; group C, normal temperature, ischemia and ligustrazine; group D, normal temperature, ischemia, mild hypothermia and ligustrazine. Establish rat models of hypoxic-ischemic encephalopathy, give each group appropriate treatment, and detect the MDA, SOD levels and GSH-Px activity of brain tissues, then compare and statistical analyze the results. Results: The MDA levels of group B, C and D were lower than that of group A, and the SOD levels and GSH-Px activity of these groups were higher than those of group A, what meant the treatments of group A were effective. The MDA'level of group D was lower than that of group B and C, and the SOD level and GSH-Px activity were higher; there were statistically significant differences ( all P〈0.05 ). In group B and C, there were no statistically significant differences on MDA, SOD levels and GSH-Px activity (P〉0.05). Conclusions: Mild hypothermia and ligustrazine can reduce brain damage caused by hypoxic ischemic. It may improve the efficacy when both treatments were used in combination.
