Lipid peroxide (LPO) in lymphocytes from mice was evaluated by measuring substances reactive to thiobarbituric acid (TBA). The product resulting from the reaction of TBA with lymphocytes was extracted with n-butyl and fluorescence intensity was determined. The degree of lipid peroxidation, expressed as fluorescence intensity f547, was assessed for(More)
Con A stimulated lymphocytes proliferation was measured as [3H]thymidine incorporation and IgG was quantified by single radial immunodiffusion to study recovering or protecting effect of selenium (Se) on immunity attacked by exogenous active oxygen species, H2O2 and60Co-radiation, respectively. Lipid peroxidation was also determined to observe the relation(More)
Lipid peroxy radicals (ROO-) were detected by electron spin resonance (ESR) at low temperature after formation by addition of H2O2 into a suspension of mice lymphocites. If lymphocytes were treated with selenomethionine (Se-Met) prior to addition of H2O2, ROO-formation was inhibited in a fashion that was dependent on Se-Met concentration. Formation of ROO-(More)
The toxicity of binary mixture of Cu(2+) and phenols (phenol; o-nitrophenol; m-nitrophenol; p-nitrophenol) was evaluated using Tetrahymena thermophila as the model organism, by microcalorimetry, optical density, field emission scanning electron microscope (FESEM) and attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR). The growth(More)
