[Antiradiation properties of adeturon and polyanion used separately and in combination].

A study was made of the radioprotective effect of polyanion, a co-polymer of maleic and methacrylic acids, administered separately and in a combination with adeturon to irradiated (8 Gy, LD100/18) H male mice. Adeturon (300 mg/kg) was injected 15 min before, and polyanion (4 mg/kg) 24 h after gamma-irradiation. The effect of the preparations was assessed by the survival rate and hematologic indices (for instance, weight and cellularity of the spleen, bone marrow cellularity, and the number of leukocytes) at defined intervals within 30 days.
