humic acid as an organic substance can bound heavy metals. it is a best way of decreasing the hazardous effect of heavy metals on plants and thereby on humans. a factorial experiment was conducted in a completely randomized design of seven replications. the treatments consisted of three cadmium levels (0, 2 and 4 mgl-1), and three humic acid levels (0, 100, 1000 mgl-1) added to nutrient solutio...
PURPOSE To evaluate the age-induced changes in corneal endothelial morphology in mice lacking the cytosolic copper-zinc superoxide dismutase (SOD-1), the interstitial extracellular superoxide dismutase (SOD-3), or both of these SOD isoenzymes. METHODS The central corneal endothelial morphologies of old C57BL-6J wild type (n=19), SOD-1 null (n=16), SOD-3 null (n=15), and SOD1/3 null (n=11) mic...
conclusions the results of our study proposed that there is a loss or inactivation of antioxidant factors, coupled with increased lipid peroxidation during the procedure of hd, possibly through the dialyzer membrane, with probable consequences on the severity of illness. results the sod, gpx and cat were decreased after hd (p < 0.05). also, frap was shown to decrease after hd (p < 0.05). howeve...
introduction : recurrent aphthous stomatitis (ras) is a common disease with unknown etiology and no treatment. the purpose of this study is to assess the relationship between serum antioxidants level and clinical manifestation. change in antioxidant level can lead inflammatory reaction through oxidative stress. materials & methods : a total 50 patients were selected for this cross sectional stu...
Photosynthetic oxygen reduction by isolated chloroplast lamellar systems has been studied with the aid of superoxide dismutase. Two mechanisms of oxygen reduction by illuminated chloroplast lamellar systems can be differentiated: 1. In the presence of low potential electron acceptors like AQ or MV the superoxide free radical ion is the product of autooxidation of the reduced acceptor. Addition ...
