The percentage of cells with positive staining was determined with flow cytometric assay. The levels of c-Myc and p53 were observed after 3 h of treatment with xanthine/xanthine oxidase. The levels of Bcl-xL and Bax were measured after 12 h of treatment with xanthine/xanthine oxidase. Data are mean ± S.E. of three independent experiments.

  • 1-150P < .05, ** P < .01 versus group treated with xanthine/xanthine oxidase alone.
