Effects of vasopressin in experimental nephroangiography.
Nephroangiography was performed in 13 rabbits using eight-fold magnification with a 0.05 mm focus. After arginine vasopressin in doses of 0.01 to 1.0 IU the glomeruli were well demonstrated as well as the subcortial arteries and veins and the concentration of contrast medium in arteries and veins increased. At increasing doses of vasopressin the glomeruli were shut off to an increasing degree, beginning at the outer part of the cortex. At 1.0 IU only the juxtamedullary glomeruli functioned.
