Fig. 2.

Alteration of vascular permeability in the skin after irradiation. Relative changes in vascular permeability from the baseline levels in the C3H mouse dorsal skin chamber are shown (see Table 1 for the actual permeability coefficient data). One day after irradiation with 2, 15 and 50 Gy, the vascular permeability increased by 1.5, 2.4 and 6.2 times, respectively, and then gradually decreased to baseline levels by day 3, 5 and 10, respectively (*P < 0.05).
