title: Effect of two graded doses of whole-body X-irradiation and radioprotection by the use of S-phenethyl formamidino 4(N-ethyl isothioamide) morpholine dihydrochloride.
abstract: The protection offered by a newly synthesized compound (S-phenethyl-formamidino-4(N-ethyl isothioamide) morpholine dihydrochloride) against radiation effects on DNA, RNA and protein biosynthetic processes in the brain, and on metabolites of 5-HT and nor-adrenalin, i.e., 5-HIAA and VMA, in the urine, including the radiobiological damage to thyroid and testes, was evaluated. The use of the compound prior to irradiation prevented radiation-induced changes in the thyroid and testes. The radiation-induced alterations in the pattern of DNA, RNA, protein in the brain, and in 5-HIAA and VMA in urine could be averted by treatment with this compound prior to each dose of X-irradiation.
