background: there is much evidence indicating that natural substances from edible and medicinal plants possess powerful antioxidant and hepatoprotective activities. the objective of the present study was to investigate the potential hepatoprotective effect of silymarin in fish exposed to malathion. methods: zebra cichlid fish were allocated into five groups of which one group received normal fe...

the present study was aimed to evaluate the therapeutic potential of pimpinella tirupatiensis (pt) by assaying the activities of selective mitochondrial enzymes in streptozotocin induced diabetic rats. diabetic rats showed a significant (p < 0.01) reduction in the activities of oxidative enzymes succinate dehydrogenase (sdh), malate dehydrogenase (mdh), glutamate dehydrogenase (gdh) and isocitr...

introduction: recently depleted uranium is being widely used as anti-armour ammunition and at very high temperature, results in information of an aerosol of very small uranium oxide particles, which may be inhaled. it is alleged that these particles represent a new battlefield hazard because of the chemical toxicology and/or radioactivity. method & materials: male wistar strain albino rats were...

background: the early stage of copper poisoning is difficult to be clinically diagnosed in sheep and has not been documented clearly yet. objectives: to assess biomarkers in predicting early copper poisoning in sheep, blood samples were collected from several groups of animals from a naturally copper poisoning occurrence in an industrial region. methods: animals were divided into four experimen...

the objective of this study was to evaluate the impact of short-term starvation and re-feeding on oxidative stress in mesopotamichthys sharpeyi (günther, 1874). after two weeks adaptation to new conditions, a total number of 270 fingerlings were distributed into nine 300-l fiberglass tanks, equipped with aeration system in three treatments including 4, 8 and 16 days starvation (each in 3 replic...

background: blood is permanently exposed to oxidation stress and therefore has a high antioxidants capacity. many different factors increasing the demand for the antioxidant capacity can be observed in the stored blood of donors. consequently, damage to erythrocytes by free radicals may occur. so it is useful to control the alternation of anti-oxidant enzymes in stored blood at different days o...

Background: Radio frequency wave (RFW) generated by mobile phones and wireless communication systems has been reported to cause adverse effects on reproductive function, vision and hematological parameters, possibly through oxidative stress. The aim of this study was to evaluate the effect of RFW generated bybase transceiver station BTS on oxidative stress in testis, eye and erythrocyte, and th...
