In this paper, we intended to further investigate the effects of small intestine (Ribonucleic acid, RNA), on gene expression of intestines of irradiated mice. This will provide theoretical bases for repair of γ-ray caused damage in small intestine. Twelve BALB/c mice were randomly divided into two groups, one for irradiated control and the other for small intestine RNA therapy (100μg/mL, 0.4mL). Eighteen hours after γ-ray irradiation with a dose rate of 138.82 cGy/min and a total dose of 1150cGy, the mice were killed and their jejunum were taken out. Fluorescent cDNA probes labeled with Cy3 and Cy5 were prepared from RNA extracted from the intestines of the two groups. The probes of the two groups were hybridized against cDNA gene chip, the fluorescent signals were scanned with a scanner and the results were analyzed by a computer codes.
