Gonadotropin and gonadal steroid release in response to a gonadotropin-releasing hormone agonist in Gqalpha and G11alpha knockout mice.
In this study, we used mice lacking the G11alpha [G11 knockout (KO)] or Gqalpha gene (Gq KO) to examine LH release in response to a metabolically stable GnRH agonist (Buserelin). Mice homozygous for the absence of G11alpha and Gqalpha appear to breed normally. Treatment of (5 wk old) female KO mice with the GnRH agonist Buserelin (2 microg/100 microl, sc) resulted in a rapid increase of serum L...
متن کاملPulsatile administration of gonadotropin-releasing hormone agonist to gilts actively immunized against gonadotropin-releasing hormone.
Sexually mature gilts (n = 20) were actively immunized against GnRH. Primary and booster immunizations of GnRH conjugated to bovine serum albumin induced production of antibodies in all gilts. Nineteen of the gilts became acyclic with suppressed concentrations of gonadotropins and estradiol. Intravenous challenges with 100 micrograms GnRH and 5 micrograms D-(Ala6, des-Gly-NH2(10)) ethylamide Gn...

متن کاملGonadotropin-releasing hormone agonist-induced pituitary apoplexy
UNLABELLED Pituitary apoplexy represents an uncommon endocrine emergency with potentially life-threatening consequences. Drug-induced pituitary apoplexy is a rare but important consideration when evaluating patients with this presentation. We describe an unusual case of a patient with a known pituitary macroadenoma presenting with acute-onset third nerve palsy and headache secondary to tumour e...
متن کاملGonadotropin-Releasing Hormone Agonist Therapy and Obesity in Girls
BACKGROUND Depot preparations of gonadotropin-releasing hormone agonists (GnRHa) are the gold standard drugs for the treatment of central precocious puberty. A concern about these drugs is obesity. OBJECTIVES This study aimed to investigate the effect of gonadotropin-releasing hormone agonists (GnRHa) therapy on body mass index (BMI) in girls with central precocious puberty (CPP). PATIENTS ...
