Berberine Ameliorates Renal Functional Disorders and Pulmonary Tissue Injury Following Renal Ischemia/Reperfusion in Rats
Introduction: This study investigated the effect of berberine on renal dysfunction and histological damages of the lung induced by renal ischemia/ reperfusion at an early stage. Methods: There were four experimental groups of adult male rats (n=7). Seven days before induction of ischemia, the Ber+I/R group received oral (by gavage) berberine (15 mg/kg/day) while the I/R group received distil...
متن کاملGlyoxalase I overexpression ameliorates renal ischemia-reperfusion injury in rats.
Methylglyoxal (MG), a highly reactive carbonyl compound generated by carbohydrate oxidation and glycolysis, is the major precursor of protein glycation and induces cytotoxicity leading to apoptosis. Although recent studies have emphasized that MG accumulates in not only chronic oxidative stress-related diseases but also acute hypoxic conditions, the pathogenic contribution of MG in acute diseas...
متن کاملEffects of normobaric hyperoxia pretreatment on ischemia-reperfusion injury in regional ischemia model of isolated rat heart
Abstract Introduction: Resent studies have been shown beneficial effects of hyperoxia pretreatment against ischemia-reperfusion injury in different organs. The aim of the present study was to investigate early and late effects of normobaric hyperoxia (≥95% O2) pretreatment on ischemia-reperfusion injuries in isolated rat hearts. Methods: Following 60 and 180 minutes of hyperoxia, rat hearts w...
متن کاملDexamethasone ameliorates renal ischemia-reperfusion injury.
In the setting of renal ischemia-reperfusion injury (IRI), the effect and mechanism of action of glucocorticoids are not well understood. In rat renal IRI, a single dose of dexamethasone administered before ischemia, or at the onset of reperfusion, ameliorated biochemical and histologic acute kidney injury after 24 h. Dexamethasone upregulated Bcl-xL, downregulated ischemia-induced Bax, inhibit...
متن کاملExtended normobaric hyperoxia therapy yields greater neuroprotection for focal transient ischemia-reperfusion in rats
BACKGROUND Normobaric hyperoxia (NBO) therapy is neuroprotective in acute ischemic stroke. However, how long the NBO should last to obtain optimal outcome is still unclear. Reports show that ischemic penumbra blood supply may remain compromised for a long period after ischemia-reperfusion, which would impair tissue oxygenation in ischemic penumbra. Therefore, we hypothesized that longer-lasting...
