chronic diabetes abolishes cyclosporine-a induced cardioprotection and nitric oxide production in rat myocardium

Nitric oxide-induced cardioprotection in cultured rat ventricular myocytes.

The aim of this study was to investigate the role of nitric oxide (NO) in a cellular model of early preconditioning (PC) in cultured neonatal rat ventricular myocytes. Cardiomyocytes "preconditioned" with 90 min of stimulated ischemia (SI) followed by 30 min reoxygenation in normal culture conditions were protected against subsequent 6 h of SI. PC was blocked by N(G)-monomethyl-L-arginine monoa...

Protective Effect of Edaravone Against Cyclosporine-Induced Chronic Nephropathy Through Antioxidant and Nitric Oxide Modulating Pathways in Rats

Background: Cyclosporine A (CsA) is an immunosuppressant with therapeutic indications in various immunological diseases; however, its use is associated with chronic nephropathy. Oxidative stress has a crucial role in CsA-induced nephrotoxicity. The present study evaluates the protective effect of edaravone on CsA-induced chronic nephropathy and investigates its antioxidant and nitric oxide modu...

Nitric Oxide-Induced Polycystic Ovaries in The Wistar Rat

Role of nitric oxide in cyclosporine A-induced hypertension.

Cyclosporine A (CsA) is an immunosuppressive agent that also causes hypertension. The effect of CsA on vascular responses was determined in Sprague-Dawley rats and isolated rat aortic rings. Male rats weighing 250 to 300 g were given either CsA (25 mg. kg-1. d-1) in olive oil or vehicle by intraperitoneal injection for 7 days. CsA administration produced a 42% increase (P<0.001) in mean arteria...

Lectin-induced nitric oxide production.

Considering that nitric oxide (NO) may be involved in anti-tumoral and anti-parasite lectin effects, in this report we investigated whether lectin induces NO production. Lectins from Canavalia brasiliensis, Dioclea grandiflora, Pisum arvense (PAA), and concanavalin A induced murine peritoneal cells to produce NO in vitro. PAA induced similar levels to that obtained with lipopolysaccharide plus ...

Cardioprotection: nitric oxide, protein kinases, and mitochondria.

Over the past 2 to 3 decades, several phenomena have been identified that provide powerful protection against myocardial infarction and other sequelae of ischemia/reperfusion1: myocardial hibernation that is related to stunning,2 ischemic preconditioning,3 delayed or second-window ischemic preconditioning,4 ischemic postconditioning,5 and their pharmacological recruitment. Stunning and hibernat...
