The purpose of this study was to assess the degree, time sequence, and biochemical correlates of hypothermic protection against ischemic acute renal failure. Rats subjected to 40 minutes of bilateral renal artery occlusion (RAO) were made mildly hypothermic (32 degrees-33 degrees C, by cold saline peritoneal lavage) during the following time periods: 1) RAO only, 2) reperfusion only (beginning ...

Activation of A(1) adenosine receptors (ARs) protects against renal ischemia-reperfusion (I/R) injury by reducing necrosis, apoptosis, and inflammation. However, extrarenal side effects (bradycardia, hypotension, and sedation) may limit A(1)AR agonist therapy for ischemic acute kidney injury. Here, we hypothesized that an allosteric enhancer for A(1)AR (PD-81723) protects against renal I/R inju...

BACKGROUND AND PURPOSE Heme-proteins, besides causing renal tubular obstruction, may contribute to rhabdomyolysis-induced renal injury through a heme-iron-mediated lipid peroxidation process. In the present study, we compared the combined therapy of a lipid peroxidation inhibitor, 21-aminosteroid (21-AS) and fluid-alkaline-mannitol (FAM) diuresis with either of them alone to determine the effic...

Leptospirosis is a global zoonotic disease caused by different Leptospira species, such as Leptospira interrogans, that colonize the renal tubules of wild and domestic animals. Thus far, attempts to develop effective leptospirosis vaccines, both for humans and animals, have failed to induce immune responses capable of conferring protection and simultaneously preventing renal colonization. In th...

Decapsulation of the left kidney through a lumbar incision immediately prior to placing young rats on a choline-deficient diet afforded a significant degree of protection against animal mortality, compared with that which occurred as a result of the deficiency in the control groups. Decapsulation also was effective in reducing greatly the renal injury which developed in the decapsulated kidneys...

BACKGROUND Remote ischaemic preconditioning (RIPC) is a strategy to protect a target organ against ischaemia-reperfusion injury (IRI) by inducing short-term ischaemia/reperfusion (I/R) in a remote organ. RIPC of the kidney by temporary limb occlusion would be a safe, inexpensive and noninvasive method to prevent renal damage in, e.g., transplantation and aortic surgery. We investigated whether ...

OBJECTIVE To review the role of drugs with potential benefit to renal function in critically ill patients. DATA SOURCES A review of articles published in peer review journals from 1966 to 1998 and identified through a MEDLINE search on kidney failure. SUMMARY OF REVIEW Acute renal failure in critically ill patients is characterised by ischaemic injury to the tubule and is potentially preven...

Both glutathione and glycine provide some protection against ischemic renal injury in a variety of experimental models. However, results have been inconsistent and there may also be model heterogeneity. The effects of glutathione, glycine, and alanine in a cell culture model of renal anoxia/reoxygenation injury were tested. When primary cultures of rat proximal tubule epithelial cells were subj...
