The fetal brain is thought to have a role in the onset and progression of labor. Evidence also exists for fetal oxytocin release just before and during parturition. The present study examined whether activation of the fetal brain could induce uterine myometrial contractions through oxytocin receptors in the dam. Under urethane anesthesia, electrical stimulation of the hypothalamus of fetal rats...

Objective: This study aims to explore the effects of light stress on the expression of Kisspeptin/GnRH in rat hypothalamus. Methods: The rat model of chronic stress was established through artificial illumination time. The rats were divided into control group, continuous light group, interval light group and reverse day and night group randomly. The expression levels of Kisspeptin and GnRH in r...
