The handling of immunoreactive vasopressin by the isolated perfused rat kidney.
Using the isolated rat kidney perfused with an artificial medium containing glucose as the sole fuel, we studied the renal handling of immunoreactive arginine vasopressin (AVP) and determined the effect of various factors on the ability of the kidney to remove AVP. In control kidneys perfused with AVP at concentrations below 116 muU/ml, the organ clearance of AVP (OC(AVP)) was 1,145+/-47 (SE) m...
متن کاملSEQUESTRATION OF LEUKOCYTES BY THE ISOLATED PERFUSED RAT LUNG
The sequestration of rat leukocytes and bone marrow cells by the lung vasculature was studied using an isolated perfused rat lung preparation. The passage of latex particles of 7.6 µm in diameter and non-hematopoietic cells through the lung blood vessels was also studied. Leukocytes and bone marrow cells were reversibly sequestered from circulation, whereas, latex particles and non-hematop...
متن کاملThe Isolated Perfused Rat Kidney
1. In the isolated rat kidney, perfused at constant pressure with a medium free from renin substrate, addition of angiotensin I to the perfusate decreases renal 'plasma' flow. 2. A peptide inhibitor, SQ 20881, of converting enzyme reduces the vasoconstrictor effect of angiotensin I up to a maximum of 87%, the degree of inhibition being dose-dependent. 3. The molar ratio of equi-effective doses ...
متن کاملThe effects of ethanol and vasopressin on renal function in the isolated perfused rat kidney
Controversial results regarding the role of vasopressin as a mediator of ethanol-induced diuresis raise the question, whether ethanol may stimulate diuresis directly on the level of the kidney, possibly by its vasodilating properties. We thus studied the effects of different ethanol-concentrations (0.5 ‰, 1 ‰, 2 ‰, and 4 ‰; n = 4 to 6, respectively) – in the presence of 10 mU/l vasopressin in t...
متن کاملGluconeogenesis in the isolated perfused rat kidney.
The perfused rat kidney was used for a study of gluconeogenesis. The kidney was completely isolated and perfused with Krebs-Henseleit bicarbonate buffer containing 5% albumin. Perfusion flow rate and pressure remained stable for 2 to 3 hours, although the glomerular filtration rate diminished with time. The fractional reabsorption of both water and sodium was 0.92 during the 1st hour of perfusi...
