  1. All data are expressed as mean ± S.E; n = 4.
  2. 12000 cells were scored for the MI.
  3. 400 cells were scored for the PI.
  4. 4000 cells were scored for the NDI.
  5. a, significant from control; b, significant from solvent control (DMSO); c, significant from positive control (MMC). a1b1c1: p < 0.05; a2b2c2: p < 0.01; a3b3c3: p < 0.001.
