IN previous studies, pressor reactivity to several standardized noxious stimuli was evaluated quantitatively, and increased responsiveness was demonstrated in hypertensive as compared with normotensive subjects." 2 The stimuli employed in these studies included simple psychologic provocation as well as the cold pressor test and the intravenous injection of a small dose of angiotensin II. Differ...

The acute effects of chlorothiazide (CTZ) on total (TSCA) and ionized (SCA-plus 2) serum calcium concentrations were studied in three groups of people: (a) eight subjects with normal parathyroid function; (b) six patients with hypoparathyroidism; and (c) two patients with hyperparathyroidism. Most subjects were studied on four occasions; at least 3 days intervened between studies on an individu...

The factors responsible for congestive heart failure as a clinical syndrome may be multiple. Although decreased cardiac output relative to inflow produces a moderate increase in venous pressure, there is a concomitant decrease in renal blood flow which may contribute to a decreased renal excretion of sodium. There is also a decrease in hepatic inactivation ( ? due to congestion) of adrenal cort...
