Abstract/OtherAbstract:
Menadione-catalyzed H2O2 production by viable cells is proportional to viable cell number. The correlations between the viable cell number and the concentration of H2O2 produced are determined with the rapid chemiluminescent assay (S. Yamashoji, T. Ikeda, and K. Yamashoji, 1989, Anal. Biochem. 181, 149-152). This chemiluminescent assay of viable cells requires only 10 min and is much faster than NR (neutral red) inclusion and MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) reduction assays, which require 3-5 h. When viable cells are incubated with antitumor drugs, detergents, mycotoxins, and glycoalkaloids for 24-48 h, a decrease in menadione-catalyzed H2O2 production in a dose- or incubation time-dependent manner is observed. In general, the 50% inhibition concentration determined by the chemiluminescent assay is lower than that determined by NR inclusion and MTT reduction assays, and the order of relative cytotoxic effects of agents is the same among these assays. Furthermore, clear cytotoxic effects are observed by the chemiluminescent assay after 1 h exposure of trypsinized cells to toxic compounds. Therefore, the chemiluminescent assay is expected to be more useful for the rapid detection of cytotoxic compounds than NR inclusion and MTT reduction assays.
