Abstract

Milk ejection reflex (MER) was studied in the lactating rat measuring the intramammary pressure during mechanical stimulation of the nipples with vacuum and pressure. The incidence of MER was 60-80% (latency 19 +/- 5 sec) after short-lasting (10-20 sec) stimulation of the nipples. The periods of MER increased when the frequency of stimulation of the nipples was decreased. The role of the mechanical stimuli in the MER occurrence in discussed.

摘要

通过在哺乳期大鼠身上测量用真空和压力机械刺激乳头期间的乳腺内压力，对喷乳反射（MER）进行了研究。在对乳头进行短暂（10 - 20秒）刺激后，喷乳反射的发生率为60 - 80%（潜伏期为19±5秒）。当乳头刺激频率降低时，喷乳反射的持续时间会增加。文中讨论了机械刺激在喷乳反射发生过程中的作用。
