Kartvelishvili T, Abuladze M, Asatiani N, Akhvlediani J, Kiziria E, Asanishvili L, Lejava L, Holman HY, Sapojnikova N: Estimation of the cellular antioxidant response to chromium action using ESR method. Invest Ophthalmol Vis Sci. 1996 Jul;37(8):1549-56.
In the present study, the antioxidant capacity of chromium-treated L-41 (human epithelial-like cells) was investigated by the ESR spin-trapping technique. The crude cell extracts of the cells grown in the presence of 2 microM (nontoxic) and 20 microM (toxic) chromium (VI) concentrations were tested in the model Fenton system with and without catalase-inhibitor sodium azide. The presented approach using the ESR technique along with inhibitors lets us discern cell extract defense capacity connected with the enzymatic activity in viable cells and the catabolic activity in dying cells. |
