title: [Changes in the sensitivity of mice to the action of gamma irradiation by Viscum album L. polysaccharides].
abstract: The influence of water-soluble polysaccharides of Viscum album L. on the survival of mice subjected to whole-body gamma-irradiation has been investigated. Polysaccharides were shown to exert a radioprotective effect which was a function of both the radiation dose and the drug dose and time of its injection. The maximum radioprotective efficacy of polysaccharides was observed after their injection 15 min before irradiation. A single intraperitoneal administration of polysaccharides (25 mg/kg) before irradiation with LD50/30 and LD100/10-12 increased the 60-day survival rate up to 95% and 27% respectively. The postirradiation injection of polysaccharides prevented death of 80% of mice given LD50 and increased the average life expectancy of animals irradiated with absolutely lethal doses.
