Figure 3.

Morphometric evaluation of intestinal segments (duodenum, jejunum, ileum, cecum, proximal colon, and distal colon) of control (CTRL, n = 5) and GK diabetic rats (GK, n = 6): total wall thickness (μm) of each intestinal segment and thickness (μm) of the intestinal layers (longitudinal muscle, circular muscle, submucosa, and mucosa) of duodenum, jejunum, ileum, cecum, proximal colon, and distal colon). Values are presented as mean ± SEM, and a 2-way ANOVA followed by an unpaired t test with Welch’s correction was used to compare the two experimental groups (CTRL and GK). * Statistical difference p < 0.05 vs. correspondent control. Unpaired t test with Welch’s correction was used to compare the two experimental groups.
