Effect of anti-digoxin antiserum on endogenous digitalis-like factor and membrane ATPase activity in hypoxic injury myocardium / 中国临床药理学与治疗学

ABSTRACT

To evaluate the protective effect of anti-digoxin antiserum on hypoxic injury myocardium and its mechanism.Methods It was observed that different concentration anti-digoxin antiserum effect on endogenous digitalis-like factor and cell membrane ATPase activity in hypoxic myocardium model.Results The level of endogenous digitalis-like factor was remarkably higher,cell membrane ATPase activity were remarkably lower in hypoxic group than those of normal group;anti-digoxin antiserum can resume membrane ATPase activity.Conclusion Rise of endogenous digitalis-like factor was basic of molecular biology of myocardial damage during myocardial hypoxia.Anti-digoxin antiserum has lightened myocardial injury and has protective effect on hypoxic myocardium by against effect of endogenous digitalis-like factor.
