摘要
用16只 SD 大白鼠建立缺血再灌流心肌损伤模型,其中8只预先静脉注射吗啡以抗心律失常。此外,再用8只大鼠开胸作正常对照。其心脏标本进行 HE 染色及抗肌动蛋白单克隆抗体(HHF_(35))免疫组化观察:对照组心肌呈均匀一致的棕褐色染色;注射吗啡后再灌流组心肌呈小灶性分布的 HHF_(35)染色缺染区;未注射吗啡组心肌缺染呈广泛大面积分布。结果表明,HHF_(35)免疫组化法对显示实验性心肌缺血再灌流损伤有重要价值,且心肌缺血再灌流损伤程度与心律失常有关。
Experimental studies on the myocardial ischemia and reperfusion injury in 16 anaethetized SDrats,of which,8 animals were pretreated with morphine(5 mg/kg,i.p.)for preventing of arrhyth-mias,were studied immunocytochemically with anti-muscle actin specific monoclonal antibody (HHF_(35)),8 shan-operated rats were used as control.With HHF_(35) ABC immunocytochemical method,the area of myocardial ischemia and reperfusion injury(without morphine)showed decrease or ab-sence of staining,large areas of staining loss were also seen.In the group with morphine,only smallfoci of staining absence were shown.The myocardium in control animals showed evenly positive stain-ing.No change were seen with HE staining in all groups.The results obtained with HHF_(35) stainingsupport its important value in studying on myocardic reperfusion injury,and indicated that the degreeof myocardic damage may be relative to the arrhythmias in myocardial reperfusion injury.
