Objective(s): In this study, we investigated the protective effects of piperine on lead acetate-induced renal damage in rat kidney tissue. Materials and Methods: Forty male rats were divided into 5 groups: negative control (rats were given aquadest daily), positive control (rats were given lead acetate 30 mg/kg BW orally once a day for 60 days), and the treatment group (rats were given piperine...

Background: Cadmium is one of the most toxic heavy metals in our environment having a very strong ability to accumulate in body organs, especially in kidney. The present study was done to determine the genotoxicity and cytotoxicity in kidneys of rats exposed to cadmium. Methods: Male rats (n=30), kept in standard conditions were used in this study. The animals were randomly divided into 2 group...

In order to improve on the technique of noninvasive detection of renal artery stenosis, we studied the effects of angiotensin converting enzyme inhibition with captopril on individual kidney hemodynamics and function as assessed by technetium-99m diethylenetriaminepentaacetic acid [( 99mTc]DTPA) renal flow studies and iodine-131 orthoiodohippurate [( 131I]hippuran) renography in experimental Go...

It has been suggested that in two-kidney, one clip hypertension, the undamped kidney (UK) actively contributes to hypertension by reducing its excretory ability in response to increased levels of Circulating angiotensin II. By exteriorizing the ureter to the dog's flank several weeks beforehand, we measured renal function directly from the UK of six chrogic renal hypertensive (> 3 weeks) and si...

The kidney transplantation surgery requires left nephrectomy because of the anatomical disadvantages. But hydroureteronephrosis is the most significant renal functional alteration of pregnancy, accounted for by both hormonal and mechanical factors. Dilatation of the ureters and renal pelvis is more prominent on the right side than the left side and is seen in up to 80% of pregnant women. A 23-y...

An investigation into the mechanism that sustains the blood pressure in chronic one-kidney hypertension in rabbits was made using passive and active immunization with hog kidney extracts containing renin and with angiotensin antagonists. Seven hypertensive rabbits were passively immunized for extended periods with antiserum prepared in other rabbits. Antirenin levels were in the range of 1-3 un...
