Abstract
The author studied dehydroascorbic acid metabolism and effect of X-ray radiation on the metabolism by means of the method of quantitative determination of ascorbic acid utilizing strong alkaline colored reaction. Dehydroascorbic acid is hardly found in urine and various organs of normal rabbit and it is rapidly reduced or dissolved in vitro as well as in vivo. The reduction capacity decreased by a minimal amount of X-ray radiation. This decrease is not due to the alarm reaction, but some factor other than SH-radical has relation to it.
