FIG. 6.
A subcutaneous incision cannot mitigate the lethal effects of radiation when administered 24 h postirradiation. Mice were irradiated with a dose approximating the LD70/30 (7.1 Gy) for that series of experiments (in which mice were anesthetized twice) and were returned to their cages for 24 h, after which a 6-mm subcutaneous incision was made. Using the Mantel-Haenzel method on 30-day surviving fractions data, no significant difference between sham-cut and 6-mm cut groups after irradiation was found (P = 0.17).
