Serum vitamin D and colonic vitamin D receptor in inflammatory bowel disease

Figure 4 Correlation between serum 25-hydroxyvitamin D3 levels and vitamin D receptor immunohistochemistry scores in control and inflammatory bowel disease patients. A: VDR scores from visually diseased mucosa were used for IBD patients (red circles); B: VDR scores from normal appearing mucosa were used for IBD patients (pink circles). VDR: Vitamin D receptor; CD: Crohn’s disease; UC: Ulcerative colitis; IBD: Inflammatory bowel disease; IHC: Immunohistochemistry.
