title: [Investigations with beagles about toxicity and radioprotective effect of the clinical radioprotection substance WR 2721. Part I. Toxicity of WR 2721 (author's transl)].
abstract: The toxicity of the chemical radioprotection substance WR 2721 (S-2-(3-aminopropylamino)ethyl-thiophosphate) was examined in 25 beagles. The study showed that the toxicity of the substance increases as the dose gets higher. Between the doses 200 and 250 mg/kg of body weight, the increase of toxicity was significantly greater than could be expected on the basis of the dose difference. Until a dose of 200 mg/kg, the authors found no side effects which would have disturbed vital functions, but higher doses led to marked symptoms of intoxication.
