Stroke is one of the leading causes mortality and disability throughout world. Recently, antioxidant therapies were attempted to reduce apoptotic cell death in cerebral ischemia animal model. To study neuroprotective properties polyphenol derived from fungal endophyte analyzed on experimental Albino rat. Polyphenols producing endophytic fungi was initially isolated seeds Moringa oleifera Lam. T...

Background: Liver ischemia / reperfusion Injury (IRI) is one of the major causes of liver failure during various types of liver surgery, trauma and infections. The present study investigates the effect of dexsamethasone on the liver injury and inducible nitric oxide synthase gene expression during hepatic warm ischemia/reperfusion in rats. Materials and Methods: 24 male Wistar rats (200-250 g)...

In this paper, we concluded that transient acidosis reperfusion conferred cardioprotection against myocardial ischemia reperfusion injury in isolated rat hearts through activating PI3K-Akt-eNOS pathway.

Myocardial ischemia/reperfusion (I/R) injury could lead to severe cardiovascular ischemic disease, including myocardial infarction and contractile dysfunction. Remifentanil demonstrated protective effect on I/R injury. The underlying pathophysiological mechanism was then investigated in this study. In the current study, primary cardiomyocytes were isolated from rats, preconditioned with remifen...

BACKGROUND/AIMS Myocardium ischemia-reperfusion (I/R) injury can be caused by imbalances in cellular metabolism. Lactate, transported by monocarboxylate transporters (MCTs), has been implicated as a mechanism in this process. The present study was designed to investigate the expression and functional role of MCTs in rat hearts during ischemia and reperfusion. METHODS Langendorff-perfused rat ...

We investigated the effect of preconditioning on ischemia-reperfusion injury in the rat bladder. Rat abdominal aorta was clamped with a small clip to induce ischemia-reperfusion injury in the bladder. Twelve-week-old male SD rats were divided into three groups; sham-operated control (Cont), 30 min ischemia-60 min reperfusion (IR) and three times of 5 min ischemia and then 30 min ischemia-60 min...

objective(s):there are a few previously reported studies about the effect of nigella sativa oil on renal ischemia-reperfusion injury (iri). the aim of the present study was to test the hypothesis whether pre- or post-treatment with n. sativa hydroalcoholic extract (nse) would reduce tissue injury and oxidative damages in a clinically relevant rat model of renal iri.    materials and methods: ir...

objective: oxygen free radicals may be implicated in the pathogenesis of ischemia reperfusion damage. the beneficial effects of antioxidant nutrients, as well as complex plant extracts, on cerebral ischemia-reperfusion injuries are well known. this study was conducted to determine the effects of the hydro-alcoholic root extract of withania coagulans on ca1 hippocampus oxidative damages followin...

BACKGROUND: Ischemia/reperfusion of tetsis is a male infertility condition which occurs because of oxidation demage. Echinacea purpurea extract (EPE) has antioxidant and protective effect. OBJECTIVES: So, the main purpose of this research was to determine effects of EP extract on testicular ischemia/reperfusion (I/R) injury in rat. METHODS: 50 adult Wistar rats were randomly allocated into five...

Objective: Several studies have shown that Chichorium intybus L. (C. intybus) which possesses flavonoid compounds has an effective role in treatment of cardiovascular diseases. Contractile dysfunction mostly occurs after acute myocardial infarction, cardiac bypass surgery, heart transplantation and coronary angioplasty. The aim of the present study was to investigate the effect of aqueous extra...
