The radioprotective efficacy of recombinant flagellin (FL) and interleukin-1 beta (IL-1) administered in combinations for preventive or therapeutic purposes was studied in experiments on white mongrel mice. The drugs were administered i.p. at doses of 1 mg/kg (FL) and 50 μg/kg (IL-1β). Simultaneous administration of the drugs in the early stages before irradiation was shown to be most efficacious in terms of 30-day survival of mice exposed to x-rays at a dose of 7.5 Gy (100% survival of mice vs. 53% survival in the control group, p < 0.01). Sequential administration of FL before exposure and IL-1β after exposure increased survival of the mice by 40% (p < 0.05). The results indicated that combined use of biotechnological drugs for radioprotection was promising.
