人体排卵时,卵子自破裂的卵泡逸出后,如何进入输卵管的繖端的机理尚不清。以前作者发现卵巢输卵管间系膜(简称MTO)有平滑肌细胞的存在,这是卵巢和输卵管繖端间连结的唯一的解剖结构。为了弄清楚上述的机理,本文对26例剖腹术妇女取出的卵巢和输卵管繖端间的输卵管系膜标本,采用肌肉室(muscle chamber)和压力换能器(pressure transducer)在体外研究了MTO的收缩活动。发现闭经后比生育期妇女的系膜短,似卵巢皮质的延长部分。全部标本中都可看到MTO有一定节律和中等强度的自发性的收缩活动。其运动在体内受内分泌状态的影响。在月经周期中的卵泡晚期(LF),MTO的收缩振幅高,次数
Human ovulation, the egg since the ruptured follicles escape, how to enter the tubal umbrella side of the mechanism is unclear. Previously, the authors found that the existence of smooth muscle cells in the ovarian tubal mesangial (MTO) is the only anatomical structure that connects the ovary and the oviduct. In order to clarify the above mechanism, in this paper, 26 patients with laparoscopic ovarian and tubal ovarian tubal removed between the tubal mesangial specimens using the muscle chamber (muscle chamber) and pressure transducer (pressure transducer) in vitro study of MTO Shrink activity. After menopause women than menopausal women found that mesangial short, like the extended part of the ovarian cortex. All samples can be seen in the MTO have a certain rhythm and moderate intensity of spontaneous contraction. Its exercise is affected by the endocrine state in the body. Late menstrual cycle in the follicles (LF), MTO contraction amplitude high frequency
