摘要 为探讨高压氧(HBO)对脑梗死患者血清脂质过氧化产物丙二醛(MDA)和超氧化物歧化酶-1(SOD-1)的浓度变化及意义，对50例患者随机分为HBO组32例行常规加高压氧治疗，常规组18例行单纯常规治疗，另30例健康志愿者作为正常组，采用硫代巴比妥酸比色法检测MDA、放射免疫法测定SOD-1。结果：治疗前MDA和SOD-1，HBO组与常规组差异无显著性(P＞0.05)，与正常组比较差异均有显著性(P＜0.01)，MDA和SOD-1呈负相关，MDA高伴随SOD-1低的患者病情较重。治疗后MDA仍较高和SOD-1低的患者其疗效与预后均差。HBO组MDA降低、SOD-1升高均较常规组显著(P＜0.01)；HBO组有效率也较常规组高(P＜0.05)。提示MDA和SOD-1与疾病的严重程度有关，高压氧治疗能观察其变化，有利于判断疗效与预后。

Abstract The changes of serum malonic dialdehyde(MDA) and superoxide dismutase (SOD-1) in the patients with cerebral infarction before and after the treatment of hyperbaric oxygenation (HBO) were investigated. Fifty patients were randomly divided into two groups: HBO group and control group and 30 health volunteers as health group. The activities of MDA were measured by using spectrometry and SOD-1 by redio-immunoassay. The results showed that before treatment there was no significant difference in the activities of MDA or SOD-1 between the HBO group and control group, but there was a significant difference between the HBO or control groups and health group (P＜0.01). There was a negative correlation between MDA and SOD-1 in treatment groups. The outcome would be worse if the patients showed higher MDA with lower SOD-1. After treatment, the patients with higher MDA and lower SOD-1 had poor therapeutic effects and worse prognosis. The decrease of MDA and the increase of SOD-1 in HBO group was more significant than in the control group and the effective rate of linguistic functional restoration and limbs functional reccovery was higher (P＜0.05). It was concluded that the changes of activities of MDA and SOD-1 were related with the severity of brain injury, prognosis of pati[1] [2] 下一页
