[Antiradiation effects of leucynferon on dogs and guinea pigs]

In experiments with two species of animals (dogs, guinea pigs) irradiated with sublethal and lethal doses of gamma-rays, it was observed, that leucynferon had antiradiation effect. Course of injections: dogs--8 injections subcutaneus: 2.0 ml (1, 3, 5, 8, 12, 14, 21, 34 days after irradiation); guinea pigs--14 injections subcutaneus, 0.2 ml (1-14 days after irradiation). Therapeutical effect was explained by capacity of the preparation to defend the hemopoietic organs from the radiation and to stimulate hemopoiesis. Leucynferon hindered the development of acute radiation sickness symptoms. Immunoreactivity of dogs and guinea pigs in experimental group was more complete and restored faster. The growth of the automicroflora on the skin was restrained. Production of interferon-gamma (which is a function of T-lymphocytes) was restored faster.
