... < 0.05). In animals on a low salt intake post-prandial right atrial pressure decreased slightly, but remained in the range of fasting values, during angiotensin II infusion. 5. Neither plasma osmolality nor plasma sodium concentration changed in any of the four protocols. 6. We conclude that the post...

... that the osmotic threshold for AVP release is normal in CRF [6]. The slope of the regression line linking plasma AVP concentration with plasma osmolality, however, is significantly increased in predialysis CRF patients [6], which may be accounted for by reduced clearance of the hormone. To test this hypothesis, we...

...M. J. Allen; V. T. Y. Ang; E. D. Bennett; J. S. Jenkins 1. Eight normal volunteers were infused with 5% saline (5 g of NaCl/100 ml) at a rate of 0.06 ml min −1 kg −1 for 120 min to increase plasma osmolality and plasma arginine vasopressin. Human atrial natriuretic peptide (α-hANP; 100 μg...

... of this plasma on Na + ,K + -ATPase activity, and its transport equivalent 86 Rb uptake, was measured in separated guinea pig renal cortical tubules. 2. Plasma from water deplete rats had a raised plasma osmolality and sodium concentration and a significant inhibitory effect on Na + ,K + -ATPase (14%) and 86 Rb...

...Yoseph Assen Mengesha; Ambachew Woreta; Belay Tesfa Mariam 1. The forearm blood flow responses to hypoxia obtained from ten subjects (ages 26–37 years) before and after propranolol showed no relation with either plasma osmolality or plasma concentrations of K + , Na + , Ca 2+ , P i and Cl...

...J. Patrick; P. J. Hilton 1. The effect of variations in extracellular osmolality from 249 to 345 mosmol/kg upon the sodium, potassium and water content of human leucocytes has been studied. 2. Similar studies were performed using human erythrocytes. 3. Changes in the leucocyte water content were...
