Abstract

To evaluate the protective effect of anti-digoxin antiserum on hypoxia-reoxygenation induced injured myocardium and its mechanism. Anti-digoxin antiserum of different concentrations was used, its effect on endoxin and ATPase activity in cell membrane in hypoxia-reoxygenation myocardium model was observed. The level of endoxin was remarkably higher, ATPase activities in cell membrane were remarkably lower in hypoxic group and hypoxia-reoxygenation injury group than those of normal group; anti-digoxin antiserum could resume ATPase activity in a concentration-dependent manner. Rise of endoxin was the molecular biological basis of myocardial damage during myocardial hypoxia-reoxygenation. Anti-digoxin antiserum had lessened myocardial injury and had a protective effect on hypoxia-reoxygenation myocardium by antagonizing effect of endoxin.
