Abstract
Oral administration of 2-aminoethianethiosulfuric acid offered a powerful protective action in mice against X-radiation of 600-800R. The effectiveness continued for more than 6hr after ingestion of the compound. The radiation protective. effect of the compound was not observed, however, in the animals which received 900RR radiation. S-Sulfocysteine was also radioprotective orally, but the effectiveness faded away in one hr.
