Abstract

The effects of a new selective beta1-adrenoceptor agonist, (--)-1-(4-hydroxyphenoxy)-3-isopropyl-amino-propanol-2-hydrochloride (H 133/22), on amylase secretion from the rat parotid gland were investigated in an in vitro system. The results were compared to the secretory responses obtained with noradrenaline, adrenaline, methoxyamine and terbutaline. H 133/22 was found to be a potent enzyme secretagogue and appeared even more effective than noradrenaline and adrenaline, particularly at low concentrations. The beta1-adrenoceptor agonist, terbutaline, also stimulated amylase discharge from the parotid gland but was much less potent than H 133/22. Methoxyamine had no effect on enzyme secretion. We suggest that the adrenergic stimulation of amylase secretion from the rat parotid gland is mainly mediated by beta1-receptors.

摘要

在体外系统中研究了一种新型选择性β1-肾上腺素能受体激动剂(-)-1-(4-羟基苯氧基)-3-异丙氨基-丙醇-2-盐酸盐(H 133/22)对大鼠腮腺淀粉酶分泌的影响。将结果与用去甲肾上腺素、肾上腺素、甲氧明和特布他林获得的分泌反应进行比较。发现H 133/22是一种有效的酶促分泌剂,尤其在低浓度时,其效力似乎比去甲肾上腺素和肾上腺素更强。β1-肾上腺素能受体激动剂特布他林也刺激腮腺淀粉酶释放,但效力远低于H 133/22。甲氧明对酶分泌没有影响。我们认为,大鼠腮腺淀粉酶分泌的肾上腺素能刺激主要由β1受体介导。
