摘要
在离体缺钙－复钙灌流（钙反常）的大鼠心脏模型上观察心钠素对钙反常心肌损伤的治疗作用。结果表明，应用１０－８～１０－６ｍｏｌ／Ｌ心钠素灌流呈浓度依赖地减轻钙反常心肌病理损伤，减少心肌蛋白、肌红蛋白和乳酸脱氢酶漏出，缓解心肌及冠脉的挛缩，抑制心肌细胞钙超载的发生，推测心钠素对钙反常心肌损伤的治疗作用和其抑制心肌细胞钙超载有关。提示，心钠素对有钙超载发生的心血管疾病可能具有治疗学意义。
The therapeutic effect of atrial natriuretic peptide( ANP)was
observed on the isolated rat heart- perfused with depletion and
repletion of calcium(Ca paradox).It was found that perfusion with
10-8-10-8 mol/L ANP concentration- dependently ameliorated myocardial
damage induced by Ca paradox; decreased leakage of myocardial protein
myoglobin and lactic dehydrogenase; attenuated constractureof
myocardium and coronary artery;and inhibited formation of myocardial
Ca- overload.It wasproposed that the therapeutic action of ANP on Ca
paradox-induced myocardial damage would be re- lated to its
inhibitory action on Ca overload. The results suggest that ANP might
have therapeutic ef-fect on cardiovascular disease with calclum
overload.
