Urinary bisphenol A and plasma hormone concentrations in male workers exposed to bisphenol A diglycidyl ether and mixed organic solvents.
AIMS To evaluate effects of exposure to bisphenol A diglycidyl ether (BADGE) on urinary excretion of bisphenol A, and plasma gonadotrophic hormones and testosterone in male epoxy resin sprayers. METHODS Cross sectional study of 42 workers whose job was to spray epoxy resin hardening agents including BADGE and mixed organic solvents, and 42 matched control workers without BADGE use in the same...
متن کاملBisphenol a induces both transient and permanent histofunctional alterations of the hypothalamic-pituitary-gonadal axis in prenatally exposed male rats.
Exposure to bisphenol A (BPA) in utero has been shown to induce alterations in the prostate of 30-d-old Wistar rats. Herein, we examine both the time course of BPA action on the rat prostate and the effects of BPA on the male hypothalamic-pituitary-gonadal axis. This was achieved by exposing rats to BPA in utero, followed by immunohistochemistry and morphometric analysis of prostatic tissue, ev...
متن کاملImbalance of testosterone level in male offspring of rats perinatally exposed to bisphenol A.
The purpose of this study was to investigate whether exposure to bisphenol A (BPA) through the placenta and milk has any effect on the reproductive system in male offspring. Pregnant rats were treated with BPA at 0, 4, 40 and 400 mg/kg body weight, from gestation day 6 through lactation day 20 by gavage. Plasma testosterone concentrations in offspring at 9 weeks old were significantly high in B...
متن کاملHypothalamic KiSS1/GPR54 Gene Expressions and Luteinizing Hormone Plasma Secretion in Morphine Treated Male Rats
Objective The inhibitory effects of Morphine and the stimulatory influence of kisspeptin signaling have been demonstrated on GnRH/LH release. Hypothalamic kisspeptin is involved in relaying the environmental and metabolic information to reproductive axis. In the present study the role of kisspeptin/GPR54 signaling system was investigated on relaying the inhibitory effects of morphine on LH horm...
متن کاملCortisol secretion in adult male rats
As a neurotransmitter or neuromodulator, brain histamine has a variety of physiological roles in brain functions such as hypothalamic- pituitary- adrenal (HPA) activity. Histamine induces the release of ACTH through the activation of hypothalamic neurons containing vasopressin and CRH. Histamine induces the activity of HPA axis directly or indirectly. Endogenous opioids modulate the (HPA) axis ...
