The presence and types of alpha and beta adrenergic receptors in the urethra and prostate of the horse were studied in vitro using adrenergic agonist and antagonist drugs. The existence of these receptors was shown. This finding was based on the observation that the contractile action was mediated by adrenergic receptors of alpha-1 type, although in the prostate alpha-2 type receptors also participated. Relaxation in both tissues was controlled by receptors of the beta-2 type.
利用肾上腺素能激动剂和拮抗剂药物,在体外研究了马尿道和前列腺中α和β肾上腺素能受体的存在情况和类型。结果表明这些受体是存在的。这一发现基于以下观察结果:收缩作用是由α-1型肾上腺素能受体介导的,不过在前列腺中α-2型受体也发挥作用。两种组织中的松弛作用均由β-2型受体控制。
