This report describes a 31-year-old woman with evidences of selective adrenocorticotropic hormone deficiency associated with a remarkable pituitary lesion, lymphoid hypophysitis. Clinical manifestations of secondary hypocortisolism, which first appeared during the immediate postpartum period following normal pregnancy, included progressive weakness and(More)
The characteristics of the inhibitory influence exerted by amiloride on active sodium transport by toad bladder and skin were taken advantage of to shed additional light on the mechanism whereby hormones-chiefly aldosterone-stimulate sodium transport across such epithelia. Toad skin treated with amiloride was as responsive to vasopressin and to aldosterone(More)
The 24-hour pattern of plasma cortisol concentration in four patients on the day before major elective surgery was compared with that of five similarly hospitalized control subjects to study the effect of the expectation of surgery on the secretion pattern. Using an indwelling venous catheter, which extended outside the patient's room, to collect blood(More)
1. The effect of progesterone on renal haemodynamics and intrarenal sodium handing was evaluated in thirteen normal men on a constant diet. Clearances were measured during maximal water diuresis and again 4-7 days later, this time 3 h after progesterone was given intramuscularly. Seven additional studies were performed 3 days after progesterone(More)
The role of augmented aldosterone production in pregnancy is poorly understood. Whereas some consider aldosterone secretion in pregnancy excessive, others suggest that this is a compensatory phenomenon. According to yet another view, mechanisms other than the renin-angiotensin-aldosterone system control sodium homeostasis in pregnancy. Metabolic balance(More)
Cytokines, which include interferons (IFNs), interleukins (ILs), and tumor necrosis factor (TNF), are immunoregulatory proteins produced by lymphocytes and inflammatory cells. Several cytokines, most noteworthy IFNs and ILs, stimulate glucocorticoid secretion. In this study, the effects of variable doses and repetitive administration of IFNs and TNF on(More)
