Testicular dysfunction in the adjuvant-induced arthritic rat
Testicular dysfunction adjuvant-induced arthritic rat
2009/2/23
Adjuvant-induced arthritis, an autoimmune disease similar to rheumatoid arthritis, was used to investigate possible mechanisms of immune system modulation of the reproductive system. This laboratory...
Secretion of plasminogen activator in response to follicle-stimulating hormone in culture medium of human testicular cells from biopsy specimens
plasminogen activator follicle-stimulating hormone culture medium human testicular cells
2009/2/23
Testicular cells from human biopsy specimens were cultured and plasminogen activator secreted into the medium was investigated. Follicle stimulating hormone stimulated plasminogen activator secret...
The changing profiles of L-ornithine decarboxylase and S-adenosyl-L-methionine decarboxylase activities in testicular cell types during sexual maturation of male rats
L-ornithine decarboxylase S-adenosyl-L-methionine testicular cell types
2009/2/23
To understand the involvement of polyamines in testicular maturation and spermatogenesis, the activity of two enzymes involved in the polyamine synthetic pathway, L-ornithine decarboxylase (ODC) a...
Polyamine profiles in rat testis, germ cells and Sertoli cells during testicular maturation
Polyamine profiles rat testis germ cells Sertoli cells
2009/2/23
Polyamine cellular concentrations (putrescine, spermidine and spermine) in the rat testis and testicular cell types were determined by fluorescence spectroscopy of their dansyl derivatives. A met...
Chronic ethanol ingestion during puberty alters the transient increase in testicular 5 alpha-reductase in the Swiss-Webster mouse
transient increase testicular 5 alpha-reductase Swiss-Webster mouse
2009/2/23
Previous experiments with inbred mice showed that chronic ethanol treatment delays male pubertal development. An initial event in sexual maturation in the rat is a transient increase in 5 alpha-re...
The pattern of LH release in the adult ram influences the testicular steroidogenic response to individual LH pulses and is regulated by testosterone negative feedback
LH release adult ram influences testicular steroidogenic individual LH pulses
2009/2/23
Two experiments were conducted with adult intact rams (approximately 58 kg in body weight) in the nonbreeding season to investigate interrelationships between LH and testosterone secretion. In Exp...
Endocrine parameters, hormone receptors, and functions of the testicular interstitium and seminiferous epithelium in estradiol-immunized Ile-de-France rams
gonadotropin secretion Leydig cells Sertoli cells FSH receptors androgen receptors
2009/2/23
The testicular response of Ile-de-France rams actively immunized against estradiol (E2) was evaluated during both the ovine nonbreeding season (spring) and breeding season (autumn). Plasma concentrati...
Pituitary-testicular reserve in men with low serum testosterone and normal serum luteinizing hormone
Pituitary-testicular reserve men with low serum testosterone normal serum luteinizing hormone
2009/2/23
Men with low serum testosterone levels who do not have elevated serum LH levels are generally thought to have hypothalamic-pituitary dysfunction. To evaluate this concept, seven men with a combinati...
The pituitary-testicular axis at rest and during moderate exercise in males with diabetes mellitus and normal sexual function
pituitary-testicular axis moderate exercise males diabetes mellitus normal sexual function
2009/2/23
Hormonal studies of pituitary-testicular function in insulin-dependent diabetes mellitus were examined at rest and during moderate exercise to assess whether diabetes per se caused abnormalities of ...
Changes in testicular morphology in boars actively immunized against gonadotropin hormone-releasing hormone
testicular morphology boars actively gonadotropin hormone-releasing hormone
2009/2/23
Alterations in testicular morphology were studied in boars actively immunized against gonadotropin hormone releasing hormone (GnRH). Ten boars were divided equally into two experimental groups (five...
