Abstract

Using the method in which leukocyte suspensions were incubated with NaF or metaproterenol at 30 degrees C for 15-30 min to allow them to convert 3H-ATP (10 muCi) to 3H-cyclic AMP, followed by separation of the formed 3H-cyclic AMP by common chromatography, the leukocyte adenyl cyclase activity of monkeys and human beings was measured with high reproducibility. The oral administration of metaproterenol increased the leukocyte adenyl cyclase activity which was stimulated by NaF and decreased the count of peripheral eosinophils in some of the monkeys. In the beta-adrenergic blockade of the monkey which was made by administration of propranolol, the leukocyte adenyl cyclase activity significantly decreased. The leukocyte adenyl cyclase from patients with coronary heart disease also decreased after oral medication with propranolol.

摘要

采用将白细胞悬液与氟化钠或间羟异丙肾上腺素在30℃下孵育15 - 30分钟,使其将3H - ATP(10微居里)转化为3H - 环磷酸腺苷,然后通过常规色谱法分离形成的3H - 环磷酸腺苷的方法,对猴子和人类的白细胞腺苷酸环化酶活性进行了高度可重复的测量。口服间羟异丙肾上腺素可增加氟化钠刺激的白细胞腺苷酸环化酶活性,并减少部分猴子外周血嗜酸性粒细胞计数。在通过给予普萘洛尔对猴子进行β - 肾上腺素能阻断后,白细胞腺苷酸环化酶活性显著降低。冠心病患者口服普萘洛尔后,白细胞腺苷酸环化酶也降低。
