An improved spectrophotometric procedure for oxidized and reduced glutathione determination in erythrocytes is described. The method is based upon a reaction using Ellman's reagent. It gave recoveries of 99 and 90% for both GSH and GSSG. The use of oxidized glutathione as an internal standard makes it accurate for simultaneous assay. The method offers the(More)
Series of amorphous SiO2, ZrO2 and HfO2 films were prepared by electron-beam evaporation at various oxygen pressures such that the packing density varied from 0.6 to 0.82. Transmittance spectra were evaluated with respect to thickness and refractive index by application of analytical formulas to the interference extrema and by dielectric modeling. The(More)
