title: Distribution and behaviour of isoselenium salts in organism. III. Radioprotective effect of selenium derivatives.
abstract: Radioprotective properties of Se-2-aminoethylioselenouronium bromide hydrobromide, 2-aminoselenoazoline and of selenium analogue of mercaptoethylguanidine were followed. Radio-protective effectiveness comparable with classical thiol radioprotectiva was manifested by 2-aminoselenoazoline. In the other two compounds there was on the contrary found a synergism of toxicity and radiation.
