Melatonin exerts beneficial effects on early liver injury by modulating hepatic oxidative stress. In order to understand the protective effect of melatonin against burn-induced hepatic injury we investigated the expression of 4-hydroxynonenal (4-HNE), a main product of lipid peroxidation and mediator of oxidative injury, the inducible heme-oxygenase-1 (HO-1), an antioxidant enzyme, and the anti...
Abstract Objectives Patients suffering from myocardial ischemia-reperfusion (IR) injuries usually have varying degrees of negatively-affecting comorbidities like hyperlipidemia. We evaluated the preconditioning effect ginsenoside-Mc1 on reperfusion injury-induced arrhythmias, along with cardiac oxidative stress, endoplasmic reticulum stress protein expression, and histological damage in hyperli...
Heme oxygenase (HO) activity leads to accumulation of the antioxidant bilirubin, and degradation of the prooxidant heme. Moderate overexpression of the inducible form, HO-1, is associated with protection against oxidative injury. However, the role of HO-2 in oxidative stress has not been explored. We evaluated survival, indices of oxidative injury, and lung and HO expression in HO-2 null mutant...
INTRODUCTION Previous studies have demonstrated that thymoquinone has protective effects against ischemia reperfusion injury to various organs like lungs, kidneys and liver in different experimental models. OBJECTIVE We aimed to determine whether thymoquinone has favorable effects on lung, renal, heart tissues and oxidative stress in abdominal aorta ischemia-reperfusion injury. METHODS Thir...
Oxidative stress is believed to be the cause of cell death in multiple disorders of the brain, including perinatal hypoxia/ischemia. Glutamate, cystine deprivation, homocysteic acid, and the glutathione synthesis inhibitor buthionine sulfoximine all cause oxidative injury to immature neurons and oligodendrocytes by depleting intracellular glutathione. Although vitamin K is not a classical antio...
Kidney injury and related diseases have become quite common in recent years, attracted more attention. Sulforaphane, a kind of isothiocyanate, is widely distributed cruciferous plants it antioxidant. Specifically, sulforaphane can reduce oxidative damage by preventing cells from freeradical damage, degeneration, acting as an anti-inflammation, etc. This study summarized the investigations effec...
We evaluated the effects of chronic hyperglycemia on L5 dorsal root ganglion (DRG) neurons using immunohistochemical and electrophysiologic techniques for evidence of oxidative injury. Experimental diabetic neuropathy was induced by streptozotocin. To evaluate the pathogenesis of the neuropathy, we studied peripheral nerve after 1, 3, and 12 months of diabetes. Electrophysiologic abnormalities ...
Objective: Effects of cotreatment with Urtica dioica (UD) methanolic leaf extract on gentamicin (GM)-induced acute kidney injury were evaluated in rats. Materials and Methods: Male Wistar rats (n=32) were separated into four groups. Gentamicin (100 mg/kg/day, IP) was injected for eight days with or without UD methanolic extract (200 mg/kg/day, gavage). Th...
Nitric oxide (NO) is a key mediator that plays an important role in pathogenesis of various chronic diseases like Alzheimer’s disease and Parkinson’s disease. Additionally, there is a great attitude for finding natural compounds, which could control and inhibit NO production in pathological conditions. Therefore, we were encouraged to investigate the effects of some Lamiaceae species on NO prod...
