Sixty Sprague-Dawley rats were randomly assigned to eight groups of seven animals each. The remaining four animals served as a pooled control. The eight experimental groups received 68 r of x-irradiation during a 10-min. exposure period. The pooled control group received only sham-irradiation. Animals were presented a choice of tap water of 0.1% saccharin solution at delays following irradiation ranging from 0 to 96 hr. Subsequent saccharin consumption was recorded for 4 days following irradiation. Results showed a decrease in saccharin consumption in groups which had first received the saccharin from 0 to 12 hr. after irradiation. No significant decrease was exhibited by groups with delays of 24 hr. or more.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
