Polychlorinated biphenyls (PCBs) are ubiquitous environmental contaminants whose exposure levels are associated with various health hazards. We hypothesized that in utero and lactational exposure to PCBs can cause changes in body composition and obesity in a mouse model. Pregnant mice were exposed biweekly to two concentrations of PCB 126 via oral gavage. Maternal PCB exposure did not result in...

We examined the effects of exogenous cortisol on plasma immunoreactive adrenocorticotropic hormone (iACTH), bioactive ACTH (bACTH), and ACTH-(1-39) in nine adrenalectomized fetuses at 126-130 and 136-140 days of gestation. Fetuses received 4 h of cortisol (2 μg ⋅ kg-1 ⋅ min-1) or saline infusions on consecutive days. Blood was obtained before and at intervals during infusions. Arterial blood ga...
