Changes in histological scores, colon length and MPO activity during oxazolone-induced colitis.

<p><b>A.</b> Tissue slices were inspected by a certified pathologist, and the inflammation severity of colonic tissues from surviving mice in each group was scored and documented. Cross-sections represent the transverse colon. Image magnifications are 100-fold and 400-fold. Scale bar, 100 µm. <b>B.</b> The histological scores were higher in the OXA mice during colitis. <b>C.</b> The colon length of the OXA mice was significantly shorter than the ETOH mice. <b>D.</b> The MPO activity was significantly increased in the OXA mice compared to the ETOH mice. n = 10 per group, *<i>p</i><0.05 versus the control mice, and ^#<i>p</i><0.05 versus the ETOH mice.
