1,25(OH)₂D₃ alleviates DSS-induced UC in mice. (A) Macroscopic appearances and colon lengths of the mice were measured. (B) Mice were given 3% DSS in drinking water for 7 d to induce acute colitis. Body weight loss. (C) The DAI of these mice during the experimental period is depicted. (D) The intestinal permeability rate of FITC-dextran was measured. (E) Representative HE-stained and TEM colon sections. The data are shown as the means ± SD; n ≥ 3, *P < 0.05, **P < 0.01.
