Background Patients receiving androgen deprivation therapy experience secondary hypogonadism, associated bone loss, and increased fracture risk. It has been shown that tocotrienol from Bixa orellana (annatto) prevents skeletal microstructural changes in rats experiencing primary hypogonadism. However, its potential in preventing bone loss due to androgen deprivation therapy has not been tested....
The effects of GnRH agonist (buserelin) on in vitro ovarian steroidogenesis were studied using DES-treated immature rats and PMS-treated immature rats. The estradiol and progesterone secreted by the cultured ovarian cells and the activities of various enzymes of steroid-metabolism were examined with or without gonadotropins (FSH or hCG), and the effects of 10(-6)-10(-12) M of buserelin on those...
Changes in proportions of luteal cells after buserelin treatment were studied in the corpus luteum (CL) that was present at the time of treatment (CLP) and in the buserelin-induced CL (CLI) of cyclic and acyclic postpartum cows. On d 0 of the experimental period, eight cyclic (Cyc-sal) cows were injected with saline, whereas eight cyclic (Cyc-bus) cows and eight acyclic (Acyc-bus) cows were tre...
This study was aimed at determining if a GnRH analogue, buserelin, could be used for ovulation induction in rabbit does submitted to artificial insemination (AI) by intravaginal administration, by adding the hormone to the seminal dose. In a first experiment, 39 secondiparous experimental does (Hyplus strain PS19, Grimaud Frères, France, of about 30 weeks of age) were divided into 3 groups of 1...
A 7 year old girl with precocious puberty was treated with buserelin, a long acting analogue of gonadotrophin releasing hormone. Spontaneous and stimulated gonadotrophin secretion became prepubertal but returned to pubertal values when buserelin was withdrawn, suggesting that normal sexual maturation should follow cessation of treatment.
Repeated administration of long acting analogues of gonadotrophin releasing hormone diminishes gonadal function and in men decreases testosterone concentrations; for this reason the effect of the analogue buserelin was studied in prostatic carcinoma. Twelve consecutive patients with newly diagnosed locally advanced or metastatic carcinoma of the prostate were treated. Each patient received intr...
gonadotropin-releasing hormone (gnrh) has neuromodulatory roles in central and peripheral nervous systems. the purpose of this study is to evaluate the effect of gnrh analog (buserelin) on peripheral nerve regeneration. forty adult male rats were divided into buserelin-treated, normal saline, sham surgery, and castrated + buserelin groups. the left sciatic nerve was crushed by a fine forceps an...
We observed structural changes in the follicles and uterus of heavy draft mares during estrus and examined the effect of a single injection of the gonadotropin-releasing hormone analog buserelin on ovulation and endocrine profiles. Twenty-two heavy draft mares were divided into a buserelin-treated group (n=8) and a control group (n=14). Mares were given an intramuscular injection of 40 µg buser...
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...
The aim of the present study, was to evaluate whether a single subcutaneous administration of the GnRH analogue buserelin could induce ovulation in the mare during the breeding season. Two studies were carried out under field conditions. In Experiment 1, 90 cycles of trotter mares aged 2-7 years, were assigned to a buserelin group (Bus1) or to a control group (Control), in the presence of a >/=...
