Sustained Hypoxic Pulmonary Vasoconstriction in the Isolated Perfused Rat Lung: Effect of α1-adrenergic Receptor Agonist
Background: Alveolar hypoxia induces monophasic pulmonary vasoconstriction in vivo, biphasic vasoconstriction in the isolated pulmonary artery, and controversial responses in the isolated perfused lung. Pulmonary vascular responses to sustained alveolar hypoxia have not been addressed in the isolated perfused rat lung. In this study, we investigated the effect of sustained hypoxic ventilation o...
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 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...
متن کاملActivation of hypoxia-inducible factors ameliorates hypoxic distal tubular injury in the isolated perfused rat kidney.
BACKGROUND Preconditional activation of HIF with specific prolyl-hydroxylase inhibitors (PHD-I) attenuates proximal tubular injury, induced by warm ischaemia/ reperfusion (Bernhardt, JASN, 2006). Distal tubular damage occurs in humans with acute kidney injury (AKI), in experimental contrast media-induced nephropathy (CIN), as well as in cell-free isolated perfused kidneys (IPKs). Since in the I...
متن کاملIron chelators do not reduce cold-induced cell injury in the isolated perfused rat kidney model.
BACKGROUND In vitro, cold-induced injury is an important contributor to renal tubular cell damage. It is mediated by iron-dependent formation of reactive oxygen species and can be prevented by iron chelation. We studied whether iron chelators can prevent cold-induced damage in the isolated perfused rat kidney (IPK) model both after cold perfusion (CP) and after cold storage (CS). We hypothesize...
