introduction: nicotinamide adenine dinucleotide phosphate (nadph) oxidase-2 (nox2) is one of the predominant sources of ros production during myocardial ischemia-reperfusion and can be induced by angiotensin ii. the evidence suggests that pharmacological blockers of renin-angiotensin system can exert direct tissue effects independent of their ability to regulate blood pressure. the mechanism(s)...

Objective(s): Resistin, as a 12.5 kDa cysteine-rich polypeptide, is expressed in hypothalamus and regulates sympathetic nerve activity. It is associated with obesity, metabolic syndrome and cardiovascular diseases. In this study, we investigated the neural pathway of cardiovascular responses induced by injection of resistin into paraventricular nucleus (PVN) with rostr...

As some of the renin–angiotensin–aldosterone system (RAAS)-dependent mechanisms underlying cognitive performance modulation could include oxidative balance alterations, in this study we aimed to describe potential interactions between RAAS modulators (Losartan and Ramipril) stress a typical model memory impairment. In study, 48 white male Swiss mice were divided into six groups received (oral a...

UNLABELLED Losartan is an orally active, nonpeptide, selective angiotensin subtype 1 (AT1) receptor antagonist. It provides a more specific and complete blockade of the actions of angiotensin II than renin or ACE inhibitors. Short term (up to 12 weeks' duration) clinical trials have shown losartan to be as effective at lowering blood pressure (BP) [causes a decrease in BP < or = 26/20 mm Hg] in...

Rheumatoid arthritis (RA) is an autoimmune inflammatory disease characterized by joint infiltration and bone damage. The aim of the present study was to evaluate the beneficial effects of losartan in adjuvant-induced arthritis (AIA). Arthritis was induced in rats by subcutaneous injection of 0.2ml of Complete Freund’s adjuvant (CFA) in the planter surface of the hind paw. Arthritic rats were al...
