1. Isolated kidneys taken from spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto rats (WKY) were perfused over a range of perfusion pressures. 2. Lithium clearance was used as an index of proximal tubule sodium handling. 3. When the perfusate contained an oncotic agent (albumin, 6.7 g/dl) the SHR kidneys performed differently from the WKY kidneys with a reduction in inulin cle...

1. Renal mechanisms of conjugated bilirubin excretion have been studied in isolated rat kidneys perfused with a protein-free dextran medium, containing conjugated bilirubin isolated from human bile. 2. In nine perfused kidneys with a low glomerular filtration rate (GFR) (less than 0.5 ml/min) and depressed tubular function, there was a significant linear correlation between conjugated bilirubin...

BACKGROUND Kidney is known as the most sensitive target organ for depleted uranium (DU) toxicity in comparison to other organs. Although the oxidative stress and mitochondrial damage induced by DU has been well investigated, the precise mechanism of DU-induced nephrotoxicity has not been thoroughly recognized yet. METHODS Kidney mitochondria were obtained using differential centrifugation fro...

The isolated perfused rat kidney experiment was introduced in 1959 for studying the regulation of renal blood flow and is recognized as a valuable preparation for studying physiological and biochemical aspects of renal function such as hemodynamics, glomerular filtration rate (GFR) and overall handling of fluids. Dose-response curves are obtained by injection of bolus doses of drugs into the pe...

objectives: mangifera indica (mango) is used in folk medicine for treatment of different types of diseases, and its anti-inflammatory and free radical scavenging activities have been demonstrated. the present study evaluated the effects of commercial (vimang) and hydroalcoholic extract of mango on gentamicin-induced nephrotoxicity in rat. materials and methods: female wistar rats were treated w...
