Rat experiments were conducted for comparative study of the effect of diuretics, injected into the organism in a single dose prior to two-and-a-half-hour ischemia of an only kidney and after it, on the extent of the kidney affection and survival of the animals. It was established that furosemid, etacryn acid and mannitol exert a preventive protective effect in ischemia of the kidneys and considerably increase the survival of rats as compared to the control-group. Analysis of the renal function in the first five days of the postischemic period testifies to the property of the above-mentioned diuretics for normalizing excretory processes on the 2nd-4th days of the action of the injuring agent, and for relieving or shortening the oligoanuric phase of acute renal failure. The significance of metabolic shifts, intratubular hydrodynamics and vascular microcirculation in the mechanism of the protective effect of diuretics in ischemia of the kidneys is discussed.
