the side effects of gonadotropin releasing hormone analog (diphereline) in treatment of idiopathic central precocious puberty
treatment of central precocious puberty (cpp) is the administration of gnrh analogs. metabolic syndrome comprised metabolic disturbances that confer increased risk of (cvd) diabetes mellitus (dm) and cardiovascular disease. this study is a longitudinal prospective study in pediatric endocrinology clinic. 30 non-obese children with idiopathic cpp were involved. total body weight, height, blood p...
متن کاملMixed analog/digital gonadotrope biosynthetic response to gonadotropin-releasing hormone.
Mammalian reproduction requires gonadotropin-releasing hormone (GnRH)-mediated signaling from brain neurons to pituitary gonadotropes. Because the pulses of released GnRH vary greatly in amplitude, we studied the biosynthetic response of the gonadotrope to varying GnRH concentrations, focusing on extracellular-regulated kinase (ERK) phosphorylation and egr1 mRNA and protein production. The over...
متن کاملSex steroids are involved in the regulation of gonadotropin-releasing hormone and dopamine D2 receptors in female tilapia pituitary.
Although molecular mechanisms underlying steroid effects on GnRH and dopamine receptors are well documented in mammals, little is known in fish. Herein, we describe the expression of pituitary GnRH and dopamine receptors relative to gonadotropin expression and release. We exposed female tilapia to graded doses of estradiol or 17alpha,20beta-dihydroxy-4-pregnen-3-one (DHP) in vitro, and of estra...
متن کاملFunction of gonadotropin-releasing hormone in olfaction.
Gonadotropin-releasing hormone (GnRH) is present within neurons of the nervus terminalis, the zeroeth cranial nerve. In all vertebrate species, except in sharks where it is a separate nerve, the nervus terminalis consists of a chain of neurons embedded within olfactory or vomeronasal nerves in the nasal cavity. The function of the GnRH component of the nervus terminalis is thought to be neuromo...
متن کاملComparing The Effects of Glycyrrhiza glabra Root Extract, A Cyclooxygenase-2 Inhibitor (Celecoxib) and A Gonadotropin-Releasing Hormone Analog (Diphereline) In A Rat Model of Endometriosis
Objective The purpose of this study was to compare the effects of Glycyrrhiza glabra (Licorice), Cyclooxygenase-2 Inhibitor (Celecoxib®) and gonadotropin releasing hormone analog (Diphereline®) to a control group on endometrial implants in rats. MaterialsAndMethods Endometriosis was induced in rats by auto transplantation and after confirmation, the rats were divided into 4 groups that were tre...
