[The antiradiation effect of the cytostatic ribamidil and the possible mechanisms of its action].

Ribamidil has a cytostatic effect on bone marrow cells and a radioprotective therapeutic action. Ribamidil favors CFUs proliferation and does not interfere with the process of CFUs migration.

[Effect of a number of sulfur-containing radioprotective agents on the evacuatory function of the stomach in mice].

Tests staged on mongrel albino mice demonstrated that sulphur-containing radioprotectors used in doses two orders below those exercising a radioprotective action with their peroral administration are apt to significantly modify the evacuative function of the stomach. This properties of the sulphur-containing radioprotectors depends upon their chemical structure. A particularly strong influence on the evacuative function of the stomach in mice exerts cystamine dichlorohydrate, aminoalkylamino-alkylthiophosphates and mercaptoamidines.
