Abstract: 目的 观察创伤性休克兔肺组织白细胞介素18(interleukin-18,IL-18)、超氧化物歧化酶(superoxidedismutase,SOD)、丙二醛(malondialdehyde,MDA)水平的变化及鸟苷酸环化酶抑制剂亚甲蓝(methylene blue,MB)的干预作用.方法 选用大白兔18只,随机分为对照组(6只)、创伤性休克生理盐水复苏组(生理盐水复苏组,6只)、创伤性休克MB处理组(MB处理组,6只),生理盐水复苏组及MB处理组测定复苏后4 h肺组织IL-18、SOD、MDA的水平,对照组测定实验末肺组织IL-18、SOD、MDA的水平.结果 兔创伤性休克复苏后肺组织IL-18及MDA明显升高,SOD明显降低,但MB处理组肺组织IL-18及MDA含量明显低于生理盐水复苏组,SOD水平明显高于生理盐水复苏组.结论 IL-18及氧自由基在创伤性休克的病理发展过程中起着重要作用,应用MB可降低肺组织IL-18及MDA的水平,增加SOD含量,对创伤性休克缺血/再灌注肺损伤有保护作用.
