Abstract

The effect of digoxin, at two different inotropic levels, was examined in normo- and hyperkalaemic dogs. For similar inotropic responses, normo- and hyperkalaemic dogs had similar levels of (Na+, K+)-ATPase inhibition and microsomal-bound digoxin.

摘要

在正常血钾和高血钾犬中,研究了两种不同心肌收缩力水平下洋地黄毒苷的作用。对于相似的心肌收缩反应,正常血钾和高血钾犬的(钠,钾)-ATP酶抑制水平及微粒体结合洋地黄毒苷水平相似。
