introduction: busulfan as a chemotherapeutic agent causes testicular germinal epithelium depletion and cytotoxicity in germ cells. the aim of this study was to assess antioxidant status, reactive oxygen species (ros) generation and apoptosis-related genetic markers of adult male mouse sperm following busulfan treatment. materials and methods: forty adult nmri mice (30 ± 5 g) were divided into t...

alzheimer’s disease (ad) is a progressive neurodegenerative disorder that affects regions of the brain that control cognition, memory, language, speech and awareness to one’s physical surroundings. the pathological initiation and progression of ad is highly complex and its prevalence is on the rise. in his study, alzheimer's disease was induced with single injection of amyloid-β (aβ) pepti...

asthma is one of the fastest growing syndromes in many countries and is adding a huge cost to the health care system. increasing reports have linked airway infectious diseases to asthma. influenza is one of the most serious airway infectious diseases and in recent years there have been some serious influenza virus pandemics which caused increased fatality in numerous different populations. dive...

glaucoma is the second leading cause of irreversible blindness and a neurodegenerative disease with a complex pathogenesis. increasing evidence suggests that oxidative stress and mitochondrial dysfunction have crucial roles in most neurodegenerative diseases such as glaucoma. the conventional clinical treatment for glaucoma is lowering the intraocular pressure (iop). some patients have normal i...

objective(s): this study was designed to indicate whether different fractions from artemisia biennis hydroethanolic extract could provide cytoprotection against oxidative stress and apoptosis induced by doxorubicin (dox) in rat pheochromocytoma cell line (pc12). material and methods:cell viability was determined by mtt assay. also, activation of caspase-3 and superoxide dismutase were evaluated...

Quercetin compounds have antioxidant, anti-inflammatory and anticancer pharmacological functions. Long-term exposure to acrylamide (AA) can cause liver injury endanger human health. However, whether quercetin attenuate AA-induced the specific mechanism are not clear. Here, we studied structure-activity relationship of in reducing hepatotoxicity vivo vitro. In studies found that quercetin-like p...

it has been hypothesized that elevated plasma homocysteine (hcy) plays a role in the pathogenesis of alzheimer’s disease (ad) and age-related cognitive decline. the mechanism of hcy neurotoxicity in the brain is controversial as well hcy is a ligand of nmda receptor. memantine, an uncompetitive antagonist of n-methyl-d-aspartate (nmda) receptors approved for the treatment of moderate to severe ...

multiple sclerosis (ms) is a neurodegenerative and autoimmune disease that it’s molecular etiology and factors involving in its progression remains unknown. in this study for evaluation effect of mercuric on progression of ms we investigated the additive effect of mercuric sulfide on the brain mitochondrial dysfunction in experimental autoimmune encephalomyelitis (eae) model of ms in c57bl/6 mi...

in this research, we investigated the cytotoxic mechanisms of cochlodinium polykrikoidescell lysate on isolated rat liver hepatocytes.this micro algae is responsible for a severe and widespread harmful algal bloom in the persian gulf and gulf of oman (2008-2009). isolated hepatocytes were obtained by collagenase perfusion of sprague-dawley rat liver.according to our results, incubation of algal...

objective(s):this study was planned to appraise the protective effect of nigella sativa fixed oil (nso) against subchronic ethanol induced toxicity in rats. materials and methods: studies were carried out on six groups of six animals each, including control (normal saline, gavage), ethanol (3 g/kg/day, gavage), nso (0.125, 0.25 and 0.5 ml/kg/day, ip) plus ethanol and nso (0.5 ml/kg/day, ip) gro...
