The hyperpolarization of the secretory cells MP and the alveolar myoepithelium contraction in response to oxytocin depend to a greater extent on the accompanying effects of catecholamines as compared with acetylcholine. The hyperpolarization of the secretory cells MP induced with oxytocin and acetylcholine diminishes in its amplitude and duration in presence of colchicine (25 microM). Rhythmic hyperpolarization changes of the MP induced with 1-minute action of oxytocin and acetylcholine coincide in time with the exocytosis period of secretory vesicles and the beginning of new biosynthesis.
与乙酰胆碱相比，分泌细胞MP的超极化以及肺泡肌上皮细胞对催产素的收缩反应在更大程度上取决于儿茶酚胺的伴随作用。在存在秋水仙碱（25微摩尔）的情况下，由催产素和乙酰胆碱诱导的分泌细胞MP的超极化，其幅度和持续时间会减小。由催产素和乙酰胆碱作用1分钟所诱导的MP的节律性超极化变化在时间上与分泌囊泡的胞吐期以及新生物合成的开始相吻合。
