High doses of Ang II receptor (AT1R) blockers (ARBs) are renoprotective in diabetes. Underlying mechanisms remain unclear. We evaluated whether high/ultra-high doses of candesartan (ARB) up-regulate angiotensin-converting enzyme 2 (ACE2)/Ang II type 2 receptor (AT2R)/Mas receptor [protective axis of the of the renin-angiotensin system (RAS)] in diabetic mice. Systolic blood pressure (SBP), albu...

background: simvastatin is a widely used medication in cardiac care. here we evaluate the role of atp sensitive potassium (katp) channels in simvastatin induced renal protection after renal ischemia/reperfusion (i/r) injury.    methods: a total of 81 male wistar rats, were treated with simvastatin (10 and 20mg/kg/day gavage, one week). some groups received glibenclamide (katp channel inhibitor ...

The induction of renal cyclooxygenase-2 (COX-2) in diabetes has been implicated in the renal functional and structural changes in models where hypertension or uninephrectomy was superimposed. We examined the protective effects of 3 mo treatment of streptozotocin-diabetic rats with a highly selective COX-2 inhibitor (SC-58236) in terms of albuminuria, renal hypertrophy, and the excretion of TNF-...

OBJECTIVE To examine the role of ethnicity and the use of anti-malarials (protective) on lupus renal disease. METHODS A nested case-control study (1:2 proportion, n = 265 and 530) within GLADEL's (Grupo Latino Americano De Estudio de Lupus) longitudinal inception cohort was carried out. The end-point was ACR renal criterion development after diagnosis. Cases and controls were matched for foll...

Objective. To examine the role of ethnicity and the use of anti-malarials (protective) on lupus renal disease. Methods. A nested case control study (1:2 proportion, n = 265 and 530) within GLADEL’s (Grupo Latino Americano De Estudio de Lupus) longitudinal inception cohort was carried out. The end-point was ACR renal criterion development after diagnosis. Cases and controls were matched for foll...

Introduction: Vincristine (VCR) is potential anti-cancer drug that is highly toxic for renal tissue. This study aimed to evaluate the protective effect of alcoholic extract of saffron stigma against vincristine renal toxicity in male rats. Methods: A total number of 50 rats were randomly divided into 10 groups. Different doses of VCR (0.25, 0.5 and 0.75mg/kg) and saffron (0.5 and ...

PURPOSE To investigate the protective effects of dexmedetomidine (Dex) against renal ischemia/reperfusion injury (IRI). METHODS Sprague-Dawley rats were randomly divided to sham group, IRI group and Dex group. The SD rats were subjected to 45 min of ischemia followed by eight weeks of reperfusion. Prior to ischemia, rats were either treated with Dex or not. Blood samples were collected for th...

Upregulation of clusterin occurs in several renal diseases and models of nephrotoxicity, but whether this promotes injury or is a protective reaction to injury is unknown. Here, in the mouse unilateral ureteral obstruction model, obstruction markedly increased the expression of clusterin, plasminogen activator inhibitor-1 (PAI-1), type I collagen, and fibronectin. Compared with wild-type mice, ...

INTRODUCTION This study reports a novel strategy for investigating the key factors responsible for the protective effect of remote ischemic preconditioning (RIPC) against renal ischemia-reperfusion (IR) injury, which remains the leading cause of the acute kidney injury that increase the morbidity and mortality in patients with renal impairment. METHODS The renal blood flow of the right kidney...
