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). Differences between all other pair-wise comparisons of treatment group profile over time were significant (p注意事项：经苏木精-伊红（H&E）染色的组织样本于100倍放大倍率的显微镜下观测。分别测量绒毛长度与隐窝深度，并在10个随机选取的视野中统计隐窝分支数目。实验数据以平均值±标准差（Mean±SD）形式呈现。针对绒毛长度指标，双因素方差分析（two-way ANOVA）结果显示，空肠与回肠的各处理组随时间变化均存在显著交互作用（所有p值均为0.05）。其余所有处理组随时间变化的组间两两比较差异均具有统计学意义（p值为0.05）。其余所有处理组随时间变化的组间两两比较差异均具有统计学意义（p值为0.05）。其余所有处理组随时间变化的组间两两比较差异均具有统计学意义（p
