Chemoprevention of MNU and Testosterone induced prostate carcinogenesis by Calcitriol (vitamin D3) in adult male albino Wistar rats
Calcitriol Chemoprevention Methyl nitroso urea Prostate cancer Prostatic intraepithelial neoplasia
2009/7/15
Background Calcitriol is a steroid hormone, inhibits the proliferation and promotes the differentiation of human prostate cancer cells. Calcitriol markedly inhibits the invasiveness of human prostate ...
Effect of hyperbaric oxygenation on peripheral nerve regeneration in adult male rabbits
hyperbaric air rabbit animal
2009/6/9
Oxygen environments were used to study the regenerative effects of hyperbaric oxygen on crushed sciatic nerves in 30 adult male rabbits. Six different oxygen environments were used, and treatments wer...

Pituitary-gonadal function in adult male rats subjected to chronic water restriction
water restriction protein-calorie deficit circadian rhythms FSH LH testosterone acute stress
2009/2/23
The effect of water restriction on the pituitary-gonadal axis has been studied in adult male rats. Water restriction did not modify FSH, LH and testosterone levels. However, both LH and testosterone...
Increased plasma and pituitary prolactin concentrations in adult male rats with selective elevation of FSH levels may be explained by reduced testosterone and increased estradiol production
Increased plasma pituitary prolactin concentrations adult male rats
2009/2/23
The roles of testosterone and estradiol in regulating prolactin concentrations were studied in acutely castrated adult male rats receiving subcutaneous Silastic implants of the sex steroids. Testost...
Recovery of gonadal functions in the adult male rat following cessation of five-month daily treatment with an LHRH agonist
LHRH agonist testicular steroidogenesis ventral prostate seminal vesicles spermatogenesis
2009/2/20
This study describes the recovery of various parameters of the pituitary-gonadal axis following five months of daily treatment of adult male rats with a potent LHRH (luteinizing hormone-releasing ...
Clinical studies in an adult male patient with “isolated follicle stimulating hormone （FSH）deficiency”
isolated FSH deficiency gonadotropin deficiency hypogonadism infertility FSH deficiency
2009/2/20
Previous reports concerning isolated follicle stimulating hormone (FSH) deficiency and its possible pathogenesis have been conflicting. Both "normal" and "abnormal" FSH response to luteinizing hormone...
Retained Undescended Testis in a 51-Year-old“Anorchic”Man: The Implications of Endocrine Evaluation in the Adult Male With Impalpable Testes
Retained Undescended Testis 51-Year-old "Anorchic" Man Implications Endocrine Evaluation
2009/2/19
A 51-year-old man with previously diagnosed bilateral anorchia was shown by endocrine investigation of his hypophyseal-gonadal axis to have functioning testicular tissue. The implications of endocri...
In Vivo and In Vitro Investigation of the Extrapituitary Antireproductive Effects of a Potent LHRH Agonist in Immature and Adult Male Rats
LHRH agonist extrapituitary reproductive effects age-dependency hypophysectomy
2009/2/19
Co-incubation with a potent LHRH agonist, D-Ala6-Des-Gly10-Pro9-NHEt-LHRH (Wy-18,481), did not affect testosterone or progesterone production by adult intact rat testes in vitro. Prior administrat...
Evidence that in a physiological setting Sertoli cell number is the major determinant of circulating concentrations of inhibin B in the adult male rhesus monkey（Macaca mulatta）
Sertoli cell number circulating concentrations inhibin B adult male rhesus monkey
2009/2/18
The relationship between changes in Sertoli cell number and function and changes in circulating inhibin B concentrations was investigated following unilateral orchidectomy (UO) in the adult rhesus...
Estrogen receptor（alpha and beta）expression in the excurrent ducts of the adult male rat reproductive tract
Efferent ductules immunohistochemistry
2009/2/17
The understanding of estrogen's function in the male reproductive tract is limited, and estrogen receptor (ER) localization in the reproductive tract of the adult male rat has not been described. ...
Acute immobilization stress disrupts testicular steroidogenesis in adult male rats by inhibiting the activities of 17 alpha-hydroxylase and 17,20-lyase without affecting the binding of LH/hCG receptors
Stress rats testosterone 17a-hydroxylase
2009/2/12
We have investigated the effect of acute immobilization (3 hours) stress on testicular steroidogenesis in the adult rat. Immobilization did not alter plasma luteizing hormone (LH) levels, but plas...
