THE PROTECTIVE EFFECT OF GLUTAMINE ON INTESTINE IN MICE DAMAGED BY RADIATION / 营养学报

ABSTRACT

Objective: To study the protective effect of glutamine on intestine in mice damaged by radiation. Methods: Mice were exposed to 137 Cs rays (dose of 4Gy) with the whole body. The protetive effects of glutamine on intestine radiational damages were studied. Result: After radiation, GSH contents, SOD activities, protein and DNA contents were decreased and MDA contents were increased in intestinal mucosa. Villus height was shortened, crypt depth was deepened, wall width and villus surface area were decreased. Glutamine supplement restrained the changes of indices above mentioned and made them close to normal levels. Conclusion: Glutamine supplement had the protective effect on radiation damage in mice.
