[An interleukin-1 beta efficacy study in the treatment of combined radiation-thermal lesions]

The experiments were carried out on F1 (CBA x C57B16) male-mice. It was shown that, in contrast to a therapeutic effect of IL-1 for the solely irradiated mice, a single subcutaneous injection of 100 micrograms/kg recombinant human IL-1 beta in 4 h after a combined radiation-thermal injury (CRTI) increased significantly the death rate of the animals within the first 2-4 days. Administration of 150 ng IL-1 per mouse in 4, 24, or 48 h after the CRTI decreased an average life-span of mice. A single injection of cytokine in 5 days after the CRTI increased the survival rate by 45%. Repeated injections IL-1 with a dose of 100 pg per mouse in 2, 4, and 6 days after the CRTI did not aid in the haematological indices and did not affect the survival rate of the animals.
