objective(s): carthamus tinctorius l. (ct) or saffloweris widely used in traditional chinese medicine. this study investigated the effects of ct extract (cte) on ischemia–reperfusion (i/r) brain injury and elucidated the underlying mechanism. materials and methods: the i/r model was conducted by occlusion of both common carotid arteries and right middle cerebral artery for 90 min followed by 24...

objective(s): renal ischemia reperfusion (ir) contributes to the development of acute renal failure (arf). oxygen free radicals are considered to be principal components involved in the pathophysiological tissue alterations observed during renal ir. the purpose of this study was to investigate the effect of co-administration of melatonin (mel) and erythropoietin (epo), potent antioxidant and an...

background: renal ischemia reperfusion (ir), one of the most important causative mechanisms of acute kidney injury, is a major clinical problem that occurs in some hospitalized patients. the aim of this study was to investigate the effects of hydroxytyrosol (ht) on renal ischemia-reperfusion injury in mice. methods: male mice were randomly assigned to three groups (n = 9): (1) sham operated, (2...

Epidemiological studies suggest that acute kidney injury has certain effect on myocardial function. In this study, for the first time, we tested a boron compound namely lithium tetraborate an act as anti-oxidant and anti-inflammatory agent in ischemia-reperfusion injury. For this, employed vivo rat model with ischemia reperfusion to evaluate cardiac clarify mechanisms of tetraborate. The evalua...

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...

Our findings demonstrate the pivotal importance of caspase-3 in regulating renal microvascular dysfunction, fibrogenesis, and long-term impairment after acute kidney injury induced by ischemia-reperfusion injury. Furthermore, this study establishes predominant role peritubular capillary integrity as a major contributor to progressive dysfunction

Background: Calcium overload and free radical mediated damage in the mitochondria is the most important pathological changes associated with myocardial ischemic-reperfusion injury. The verapamil post-treatment has been previously reported to prevent reperfusion-induced myocardial injury but functional recovery may be delayed due to the drug's inherent direct myocardial depression effect. In the...

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)...

Organ damage after reperfusion of previously viable ischemic tissues is defined as ischemia/reperfusion injury. The pathophysiology of ischemia/reperfusion injury involves cellular effect of ischemia, reactive oxygen species and inflammatory cascade. Protection against ischemia/reperfusion injury may be achieved by preconditioning or postconditioning. In this review, we discuss basic mechanisms...
