Abstract
Phenylephrine (0.1-100 microM) in the presence of 1 microM propranolol increased the force of contraction in electrically driven papillary muscles from cats. This presumably alpha-adrenoceptor mediated positive inotropic effect of phenylephrine occurred without any influence on (Na+ + K+)-ATPase activity.
摘要
在存在1微摩尔普萘洛尔的情况下，去氧肾上腺素（0.1 - 100微摩尔）增加了猫的电驱动乳头肌的收缩力。去氧肾上腺素这种可能由α-肾上腺素能受体介导的正性肌力作用对（钠+钾）-ATP酶活性没有任何影响。
