The minimum dose of x-rays able to alter in vivo intestinal absorption of glucose

Abstract

The minimum dose of X-rays necessary to alter the intestinal absorption of glu­cose within 96 hours after irradiation is between 50 and 100 r. With 100 r absorp­tion increases 45 % at 96 hours, white with 600 r at 96 hours there is a decrease of the same magnitude. Cysteamine is seen to be an effective radioprotector, eliminating the aforementioned increase in glu­cose absorption.
