1. From a single strain of Wistar rats two lines of normotensive rats (NR) and two lines of hypertensive rats (SHR) were developed by selective breeding. 2. One line of normotensive rats and one of hypertensive rats were used as recipients and the remaining two were used as donors for cross-transplantation of kidneys from hypertensive to normotensive rats and vice versa. Transplantations betwee...

The role of nitric oxide (NO) and prostaglandins (PG) in modifying renal hemodynamics was examined in clipped and nonclipped kidneys of unilateral renal artery stenosis. Chronic unilateral renal ischemia was established by 4-wk-clipping the left renal artery of canine kidneys, and renal interstitial nitrate+nitrite and PGE(2) contents were evaluated by the microdialysis technique. Unilateral re...

BACKGROUND AND PURPOSE Reducing extracorporeal shockwave lithotripsy (SWL) time by increasing the shockwave rate of the lithotripter has been tested in the past; however, basic research and treatment outcomes revealed that this is not convenient. The purpose of this study was to use an animal model to demonstrate that SWL treatment time can be reduced significantly without sacrificing stone fra...

A byproduct of experience with the artificial kidney was the detection of reversible electrocardiographic "currents of injury" in patients with electrolyte imbalance. These changes occurred irrespective of anatomic alterations and resembled the changes of acute pericarditis or myocardial infarction. The electrolyte basis for the "current of injury" was established by the prompt abolition of the...

Background: Meckel-Gruber Syndrome (MGS) is a rare autosomal recessive congenital syndrome with triad of encephalocele, polydactyly, and polycystic kidneys. The worldwide incidence of the MGS is 1 in 1.3-1 in 140,000 live births. The highest incidence of 1 per 1,300 live births (carrier rate of 1 in 18) was reported in Gujarati Indians. MGS is caused by mutation in the...
