Ph ysiol. 2 15 ( 1) : 7 l-74. 1968.~The effect of prolonged 9-alphafluorohydrocortisone administration on sodium and calcium excretion was investigated in rats fed a low-calcium synthetic diet. In rats fed salt the administration...

BARATZ, ROBERT A. AND RAYMOND C. INGRAHAM. Renal hemodynamics and antidiuretic hormone release associated with volume regulation. Am. J. Physiol. Ig8(3) : 565-570. rg6o.-Following the general reduction of extracellular fluid volume by hemorrhage, or the selective reduction of this volume in the thorax by positive pressure breathing, the volume regulating mechanism of the dog is implicated as pa...

1. The effect of 5 consecutive days of hill walking on electrolyte balance, fluid homeostasis, plasma renin activity and plasma aldosterone concentration was studied in five male subjects. 2. The 5-day exercise period was preceded by a 4-day control period and followed by a 4-day recovery period. Throughout the 13-day study subjects ate a fixed diet. 3. After 5 days of exercise subjects had ret...

Experiments are described in which it is shown that the estrogenic hormone (alpha-estradiol propionate) increases the amount of extracellular fluid in the skin. Since previous work showed that this hormone increases resistance of rabbits to vaccinia virus, it is suggested that the increased resistance is the result of increased fluid in the tissues. In further test of this thesis, experiments w...

Sequential changes in arterial pressure, renal function, body fluid, and electrolyte balance, and several hemodynamic variables were examined during chronic intravenous infusion of aldosterone (14 micrograms/kg/day) in eight conscious dogs maintained on 250 mEq/day sodium and 140 mEq/day potassium intake. Arterial pressure gradually increased and stabilized at 132% +/- 3% (p less than 0.05) of ...

Splenectomized and adrenalectomized-splenectomized dogs, anesthetized with pentobarbital, were bled so that the role of cortisol in restitution of blood volume could be examined. Intact dogs and adrenalectomized dogs infused with cortisol at a high rate (17 mug/min) showed restoration of blood volume and plasma protein at 24 h, preceded by an early increase in plasma osmolality. Adrenalectomize...
