GI tract hyperplasia at 7 and 14 days after radiation treatment.

Note: H&E stained tissues were observed under a microscope with 100× magnification. Villous length and crypt depth was measured, no. of crypt branching were calculated in ten random fields. Data are expressed as Mean±SD. For villous length, two way ANOVA showed significant interactions over time between treatments in jejunum and ileum (all p0.05). Differences between all other pair-wise comparisons of treatment group profile over time were significant (p0.05). Differences between all other pair-wise comparisons of treatment group profile over time were significant (p0.05).
