目的 观察硫化氢（H2S）预处理对兔脊髓缺血再灌注损伤的保护效应。方法 将雄性新西兰大白兔随机分为假手术组、缺血再灌注组和H2S预处理组，观察H2S对模型神经行为学的影响，以及对神经细胞凋亡和超氧化物歧化酶（SOD）、过氧化氢酶（CAT）的影响。结果 H2S预处理提高神经功能的评分，降低神经细胞的凋亡，增强SOD和CAT活性（P＜0.05）。结论 H2S对脊髓缺血再灌注损伤有较好的保护作用，其作用机制可能与抗自由基生成有关

Objective To research the protection of hydrogen sulfide (H2S) on spinal cord ischemia and reperfusion injury in rats. Methods Male New Zealand white rabbits were randomly divided into three groups: Sham group, spinal cord ischemia reperfusion injury group, and hydrogen sulfide treatment group. The effect of H2S on model rabbits was investigated for the neurological behavior, neuron apoptosis, superoxide dismutase (SOD), and catalase (CAT). Results H2S pretreatment improved neurological function score, reduced neuronal apoptosis and enhanced the activity of SOD and CAT (P <0.05). Conclusion H2S produces a protective effect on spinal cord ischemia-reperfusion injury and the mechanism may be related with the generation of anti-free radicals.
