EVALUATION OF RADIOPROTECTIVE AGENTS.

Abstract

A study is in progress to determine whether standard radioprotective agents (beta-mercaptoethylamine, p-aminopropiophenone, 2-aminoethylisothiouronium bromide, and serotonin) will protect mice against the late deleterious effect of X-ray exposure. A total of 7200 treated and control mice have been exposed to four dosage levels of X rays and set aside for longevity and histopathology studies. Both sexes from strains A/J and C57BL/6J have been included. Seven radioprotective agents provided by the Walter Reed Army Institute for Research have been evaluated in terms of chemical toxicity and radioprotective effect. The ratios of X-ray LD50 values for treated mice to the control LD50 values ranged from 1.2 to 1.6. The comparable values for the standard agents listed above were 1.5 and 1.8. (Author)
