in order to investigate the effects of peppermint (mentha piperita l.) alcoholic extract on liver injury caused by the oxidant carbon tetrachloride (ccl4), an experiment was performed as a completely randomized design in a factorial arrangement (2 × 2) with 4 replications of 10 broilers each. factors included two levels of peppermint leaf alcoholic extract (0 and 2 ml/kg body weight) and ccl4 (...

conclusions the present study indicated a hepatoprotective effect of loe in diabetic rats. background plants have been the basis for medical treatments throughout much of human history. although the active compounds of many herbal drugs are unknown, they have been widely prescribed by traditional medicine practitioners due to their beneficial effects and low cost. although the primary feature o...

oxidative stress (os), which has been implicated in pathogenesis of many acute and chronic diseases, plays an important role in diverse neurological disorders including depression and anxiety. os is caused by a large amount of reactive oxygen species or impaired enzymatic or non-enzymatic defense against it. os has been suggested to contribute to etiology of mentioned disorders. this review int...

background: the aim of this study was to examine the renoprotective effect of hydro alcoholic sage (salvia officinalis: so) leaves extract against gentamicin-induced nephrotoxicity in rats. methods: in this experimental study forty male sprague dawley rats weighing 200-300 g were randomly divided into 5 groups; (1) the rats without treatment (control), (2) intraperitoneally injected with normal...

introduction: cypermethrin causes its neurotoxic effect through voltage-dependent sodium channels and integral protein atpases in the neuronal membrane. brain and nerve damage are often associated with low residual level of pesticides. in vitro and in vivo studies have also shown that pesticides cause free radical-mediated tissue damage in brain. propolis has antioxidant properties. the main ch...

background: excess reactive oxygen species (ros) in the semen is believed to affect fertility in men. morphologically abnormal sperms and their relation to seminal oxidative stress in infertile and subfertile men are not clear. objective: to correlate various sperm morphological defects with seminal oxidative stress in infertile and subfertile men. materials and methods: the study included 25 p...

background: oxidative stress is described as the formation of toxic effect due to the deficiency of cellular antioxidative level toward the level of reactive oxygen species (ros). the excess production of ros or the decrease in the antioxidative defense system could be the cause for oxidative stress. 7,12-dimethylbenz[a]anthracene (dmba) that is known to be the major cause the increment in lipi...

background and objective: a huge amount of investigational evidence support a role for oxidative stress as an intermediary of nerve cell dysfunction in parkinson’s disease (pd). polyphenols such as carvacrol have been indicated to prevent neuronal deterioration caused by increased oxidative load, thus, this study evaluated whether carvacrol administration would attenuate behavioral abnormalitie...

neurodegeneration is a complex and multifaceted process leading to many chronic disease states. a conventional definition implies a progressive neuronal death, which usually affects a specific population of nerve cells the vulnerability of which determines the clinical manifestations of a particular neurodegenerative disease. the neurodegenerative process is associated with many events. each ev...

This critical review evaluates the state-of-the-art in propane dehydrogenation catalysis using oxidative and non-oxidative methods, with an emphasis on sustainability suitability for process commercialisation.
