The 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 کاملdissociation of structure and function after ischaemia-reperfusion injury in the isolated perfused rat kidneys
oxygen-derived free radical* (ofr) involvement in ischacmia-rcpcrfusion (ir) injury was investigated in a rat isolated kidney model, using 20 minutes iscliaemia followed by 15 or 60 minutes reperfusion. two antioxidants, the xanthine oxidase inhibitor allopurinol and the hydroxyl radical scavenger dimcthylthiourca (dmtu), were uscit to try and prevent ofr-relatcd damage. renal function was esti...
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 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 کاملthe underlying structure of language proficiency and the proficiency level
هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
