25. Changes in serum and urinary calcium during phosphate depletion: studies on mechanisms
The changes in serum calcium and the renal handling of this ion were evaluated during phosphate depletion. 96 renal clearance studies were carried out in 10 dogs before and after prolonged phosphate depletion (30-160 days) and after repletion. Depletion was produced by reducing phosphate intake and administering aluminum hydroxide gel while intakes of sodium

27. Membrane Lipid Depletion in Hyperpermeable Red Blood Cells: Its Role in the Genesis of Spherocytes in Hereditary Spherocytosis*
Hereditary spherocytosis (HS) red cells lose membrane lipids excessively during incubation in vitro. Individual phosphatides as well as cholesterol are lost in proportion to their content in membranes, suggesting that fragments of membrane are removed. Supplementation of HS red cells with glucose during incubation has no consistent protective effect, whereas

29. Increased renal secretion of norepinephrine and prostaglandin E2 during sodium depletion in the dog.
To determine whether vasoactive renal hormones modulate renal blood flow during alterations of sodium balance, simultaneous measurements of arterial and renal venous concentrations of norepinephrine and prostaglandin E2 (PGE2) and of plasma renin activity, as well as renal blood flow and systemic hemodynamics were carried out in 24 sodium-depleted and 28 sod

30. Renin-Angiotensin System Inhibition in Conscious Sodium-Depleted Dogs: EFFECTS ON SYSTEMIC AND CORONARY HEMODYNAMICS
The role of the renin-angiotensin system in the regulation of the systemic and coronary circulations during sodium depletion was studied in conscious normotensive dogs by i.v. administration of teprotide (0.5 mg/kg), an angiotensin-converting enzyme inhibitor, and saralasin (0.05-5 μg/kg per min), an angiotensin-receptor antagonist. Sodium depletion was pro

36. Glomerular Hemodynamics in Rats with Chronic Sodium Depletion: EFFECT OF SARALASIN
In chronic sodium depletion the glomerular filtration rate may be reduced, and alterations in proximal tubular function may contribute to the maintenance of antinatriuresis. Measurements were made by micropuncture technique in superficial nephrons of the Munich-Wistar rat of (a) the determinants of glomerular filtration rate, (b) peritubular capillary hydros
