We studied the pattern of plasma active renin concentration (ARC), prorenin concentration (PRC), renal renin concentration, and the renin mRNA levels in ovine fetuses subjected for 24 h to reduced renal perfusion pressure (RPP). The results obtained

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

OBJECTIVES: Our purpose was to determine whether chronic physiologic elevations in plasma angiotensin II levels decrease plasma renin concentration, alter the relationship between active renin and prorenin in fetal plasma and kidney, and depress the

The purpose of this study was to determine the effects of corticotropin-releasing factor (CRF) or arginine vasopressin (AVP) on the secretion of bioactive adrenocorticotropic hormone (bACTH) and immunoreactive ACTH (iACTH), the latter being measured

Objective: Our purpose was to test the hypothesis that a long-term physiologic elevation of plasma cortisol would not alter the basal plasma concentrations of immunoreactive and bioactive corticotropin, yet it would evoke an increase in the ratio of

The regulation of CRF mRNA and protein in the developing ovine brain has been studied to assess the hypothesis that CRF is differentially regulated in the hypothalamus (Hypo), hippocampal-amygdala complex (H & A), frontal cerebral cortex (FCC) and br

The late-gestation ovine fetus (> 130 days, 0.90 gestation, full term 145 days) is capable of increased pituitary-adrenal activity following a variety of stressors. To examine the relationship between plasma immunoreactive adrenocorticotropic hormone
