Treatment | AP+ foci/cm2 | Fold increase |
---|---|---|
None | 15 ± 10 | 1 |
Camptothecin | 34 ± 38 | <3 |
Etoposide | 260 ± 130 | 17 |
8 Gy of γ-irradiation | 310 ± 200 | 21 |
12 Gy of γ-irradiation | 540 ± 180 | 36 |
17 Gy of γ-irradiation | 1970 ± 450 | 130 |
Mice received 1 × 105 ffu of CWRAPSP and the indicated treatment on day 1, and livers were fixed with 2% paraformaldehyde and stained for AP on day 6. Mean numbers of AP+ foci per cm2 ± SD are reported for three or four mice in each group. The number of mice injected by tail vein (t) or direct liver injection (d) for each treatment was as follows: none (t = 1, d = 3), 17 Gy (t = 3), 12 Gy (t = 3), 8 Gy (t = 2, d = 1), camptothecin (t = 1, d = 2), and etoposide (t = 1, d = 3).
