Using the isthmic circular ring from 76 subjects, the authors investigated the in vitro mechanical response of the fallopian tube to noradrenalin and field stimulation. In the proliferative and menopausal phases, preparations with high plasma levels of estradiol showed a high contractile response. In the secretory phase, responses were inhibitory or low at 4 to 6 and 11 to 14 days after the elevation of basal body temperature and were excitatory at 0 to 3 and 7 to 10 days. The exogenous application of estradiol failed to suppress these inhibitory responses. The findings suggest that the inhibitory response at 4 to 6 days after the elevation of BBT may aid in the release of the ovum from the fallopian tube and that after the ovulation, progesterone is mainly related to the response of the circular muscle to noradrenalin.
作者使用76名受试者的峡部环形组织，研究了输卵管对去甲肾上腺素和电场刺激的体外机械反应。在增殖期和绝经期，雌二醇血浆水平高的组织表现出高收缩反应。在分泌期，基础体温升高后4至6天和11至14天反应为抑制性或较低，而在0至3天和7至10天为兴奋性。外源性应用雌二醇未能抑制这些抑制性反应。研究结果表明，基础体温升高后4至6天的抑制性反应可能有助于卵子从输卵管释放，排卵后，孕酮主要与环形肌对去甲肾上腺素的反应有关。
