objective(s):therapies with high levels of oxygen are commonly used in the management of critical care. however, prolonged exposure to hyperoxia can cause acute lung injury. although oxidative stress and inflammation are purported to play an important role in the pathogenesis of acute lung injury, the exact mechanisms are still less known in the hyperoxic acute lung injury (hali).   materials a...

objective(s) the purpose of this study was to investigate the role of oxidative stress in purkinje cell neurotoxicity ofethanol-treated rat. materials and methods male rat pups 4-day-old was used in this study. ethanol was administered to rat pups at a dose of 6 g/kg from postnatal days (pds) 4 to 5.  pups were killed 90 min after the second alcohol treatment on pd 5 by decapitation and the bra...

objective(s) comparison of prooxidant-antioxidant balance (pab) assay with crocin assay. materials and methods twenty eight serum samples were chosen, pab and the total antioxidant capacity were measured by pab assay and crocin, respectively, and the correlation of both assays, along with their correlation with other clinical and biochemical parameters, were determined. results a significant ne...

objective(s): in the current study, the effects of selected folk medicinal herbs were evaluated in d-galactose-induced aging in male mice.   materials and methods: male balb/c mice were randomly divided into 12 groups composing sham, control, and treated groups. aging was induced by administration of d-galactose (500 mg/kg/day for 6 weeks). a positive control group was assigned that received vi...

objective(s): in the present study, our aim was to investigate the possible protective effects of epigallocatechin gallate (egcg) on lipopolysaccharide (lps)-induced hepatotoxicity by using hep3b human hepatoma cells. specifically, the study examines the role of some proinflammatory markers and oxidative damage as possible mechanisms of lps-associated cytotoxicity. consequently, the hepatocellu...

objective(s): gentamicin is used for the treatment of gram-negative bacterial infections. however, gentamicin administration is limited because of nephrotoxicity. the aim of the present study was to evaluate the protective effect of crocin against gentamicin-induced nephrotoxicity in rats. materials and methods: thirty two male wistar rats received gentamicin (100 mg/kg, ip), with or without cr...

conclusions the nps-induced ots may increase the pro-inflammatory responses. on the other hand, administration of antioxidants such as nac and vitamin c and e prior to exposure to metal nps significantly decreases ots conditions. evidence acquisition here, a nanotechnology approach is evaluated using nps in human neuronal protection against ots. it may be wide therapeutic applications in the ca...

results the results reveal that pq can decrease mitochondrial viability, deplete gsh content, increase mitochondrial ros formation, and enhance lpo and mitochondrial membrane damage. the pretreatment of mitochondria with ng has the ability to reduce the toxic effects of pq in isolated mitochondria. background paraquat (pq) is a dipyridyl herbicide that sustains damage due to redox cycling. an i...

abstract background: recent studies have suggested that oxidative stress (os) may have a contribution in the pathogenesis of endometriosis. however, the results of previous studies regarding os in endometriosis are controversial. the objective of this study was to compare the serum levels of os markers in endometriosis versus the control group. methods: this case-control study was carried out o...

genistein is a soya isoflavone, which is found naturally in legumes, such as soybeans and chickpeas. the intraperitoneal administration of the optimum dose (200 mg/kg) of genistein 24 h and 15 minbefore irradiation (8 gy at a dose rate of 1.02 gy/min) recovered the deficit in protein content (28.63±1.44%) and the dna content (21.61±8.19%) if an average of 5 intervals of autopsies 1st, 3rd, 7th,...
