Abstract
Six healthy males received vasoactive intestinal polypeptide (VIP; 6 pmol kg-1 min-1) by intravenous infusion for 90 min, with 60 min control periods before and after. Plasma VIP levels rose by about 100 pmol l-1 during the infusion. VIP produced changes in heart rate and blood pressure consistent with generalized vasodilatation, but there were no significant changes in effective renal plasma flow or glomerular filtration rate. Both plasma solids and haematocrit rose by about 5%, suggesting that haemoconcentration had occurred during VIP infusion. Urine flow fell to about a third, and the fractional excretion of sodium, potassium, chloride and calcium fell to between half and two-thirds of control values. Fractional excretion of phosphate did not fall significantly. Plasma renin activity rose about 3-fold during VIP infusion.Entities:
