Keyword:  心肌缺血再灌损伤腹腔氢气饱和氢盐水自由基氧反应激超微结构;
Abstract: 目的探讨腹腔氢气和静脉饱和氢盐水对家兔心肌缺血/再灌注损伤及心肌超微结构的影响。方法将40只家兔麻醉开胸随机分为假手术组(A组)、模型对照组(B组)、腹腔氢气组(C组)和饱和氢盐水组(B组)各10只。假手术组冠脉穿线不结扎,余3组冠脉结扎60min后再灌注同时,B组5只腹腔氧气10mL/kg一次性注入,5只静脉生理盐水10mL/kg10min泵入,C组腹腔氢气10mL/kg10min注入;D组静脉饱和氢盐水10mL/kg泵入。B组、C组D组均再灌480min。结果 A组、C组、D组超氧化物歧化酶(SOD)明显高于B组,但A组、C组、D组间两两比较差异无统计学意义(P>0.05);A组、C组、D组抑制羟自由基能力明显大于B组。电镜和Tunnul监测显示:A组、C组、D组细胞凋亡数明显少于B组,心肌结构相对完整,线粒体细胞核损伤较小,仅见少量溶酶体无自噬体,而B组心肌组织破坏严重细胞膜线粒体脊融合断裂较重,形成空泡部分溶酶体空泡形成,可见多个自噬体。结论两种给氢方法均能保护缺血再灌注损伤,这种保护作用与H2清除自由基抗炎、抗凋亡有关。腹腔氢气较静脉氢盐水应用方便效果更佳。
