Radioprotective Properties of Indralin in Combination with Monizol in the Treatment of Local Acute and Delayed Radiation Injuries Caused by Local Skin γ-Irradiation.

Female rats were exposed to local γ-irradiation of the right hindpaw in doses of 30-50 Gy at 131-154 sGy/min dose rate. Radioprotector indralin was administered per os 15 min prior to irradiation, monizol was injected intraperitoneally 5 min after irradiation. Indralin showed marked radioprotective properties both for acute and delayed symptoms of local radiation injuries. In combination with monizol, radioprotective effect of indralin was potentiated to dose reduction factor of 1.4-1.5 both for radiation burn severity reduction and for restriction of postradiational contracture development and amputation of the irradiated limb.
