A single dose of allopregnanolone affects rat ovarian morphology and steroidogenesis
(BioScientifica, 2016-10)
Allopregnanolone, a progesterone metabolite, is one of the best characterized neurosteroids. In a dose that mimics serum levels during stress, allopregnanolone inhibits sexual receptivity and ovulation and induces a decrease ...
Stress promotes development of ovarian cysts in rats: The possible role of sympathetic nerve activation
(1998)
Activation of the sympathetic innervation precedes the induction of polycystic ovaries in rats given estradiol valerate (EV). The mechanism of induction by EV may thus involve both direct and neurogenic components. We ...
Uterine Involution, Fluid Accumulation and Ovarian Activity after Injection of Prostaglandin at Different Periods of Buffalo Puerperium
(Int Buffalo Information Ctr, 2013-01-01)
This study aimed to evaluate the effect of chloprostenol administration, at early or intermediary puerperium, under uterine involution, intrauterine fluid accumulation and ovarian activity return. 30 Murrah postpartum ...
Prepubertal administration of estradiol valerate disrupts cyclicity and leads to cystic ovarian morphology during adult life in the rat: Role of sympathetic innervation
(ENDOCRINE SOC, 2003-10-01)
Administration of estradiol valerate (EV) to adult rats leads to anovulation and cystic ovarian morphology. Sympathetic ovarian nerve denervation (SONX) overcomes this disruption. In this study, we determined whether EV ...
Treatment with the synthetic PPARG ligand pioglitazone ameliorates early ovarian alterations induced by dehydroepiandrosterone in prepubertal rats
(Polish Acad Sciences Inst Pharmacology, 2019-02)
Background: Peroxisome proliferator-activated receptor gamma (PPARG) is a nuclear factor that may act on the early development of ovarian follicles and on follicular steroidogenesis. However, the exact mechanism of PPARG ...
Effect of paprika on the ovarian development of Africanized honeybee workers (Apis mellifera L.) in queenless colonies
(California State University, 2008-01-01)
This paper deals with the influence of paprika in the ovarian development of Africanized honeybee workers in recently orphaned colonies. A beehive, whose queen had been naturally mated, was divided into two orphan nuclei. ...
Post breeding peritonitis in a Boxer bitch with ovarian remnant syndrome (ORS)
(Univ Fed Rio Grande Do Sul, 2009-01-01)
The ovarian remnant syndrome (ORS) is defined as the persistence of ovarian activity in surgically spayed females, in which part or the entire ovary remains after the surgical procedure. ORS is characterized as a neo-vascular ...
Kisspeptin is involved in ovarian follicular development during aging in rats
(Bioscientifica, 2016)
We have previously reported that kisspeptin (KP) may be under the control of the sympathetic
innervation of the ovary. Considering that the sympathetic activity of the ovary increases with aging,
it is possible that ...
