The intraperitoneal injection of isoprenaline in rats caused an increase in myocardial ornithine decarboxylase activity which reached a maximum of about four times the control value one hour after the injection. The intraperitoneal injection of dl-propranolol had no effect on myocardial ornithine decarboxylase activity. The injection of dl-propranolol 30 min before the injection of isoprenaline almost completely prevented the effect of isoprenaline.
给大鼠腹腔注射异丙肾上腺素会导致心肌鸟氨酸脱羧酶活性增加，注射后1小时该活性达到最大值，约为对照值的四倍。腹腔注射dl-普萘洛尔对心肌鸟氨酸脱羧酶活性没有影响。在注射异丙肾上腺素前30分钟注射dl-普萘洛尔几乎完全抑制了异丙肾上腺素的作用。
