Ortho-substituted polychlorinated biphenyl (PCB) congeners (95 or 101) decrease pituitary response to thyrotropin releasing hormone.


Polychlorinated biphenyl compounds (PCBs) are global environmental contaminants that cause disruption of the endocrine system in humans and wildlife. Recently, we reported that acute exposures to ortho-PCB congeners 95 (2,3,6-2',5') or 101 (2,4,5,-2',5') causes changes in the performance of the hypothalamo-pituitary-thyroid (HPT)-axis in developing rats… (More)
