Electroacupuncture ameliorates dextran sulfate sodium- (DSS-) induced colitis in C57BL/6 mice. (a) Experimental protocol of 3.5% DSS colitis and electroacupuncture (EA) ST36 treatment course. (b) Mice body weights change from baseline after 3.5% DSS induction of colitis. (c) Intestine photograph of colorectum length in each group. (d) Representative H&E-stained colorectum sections (200x magnification) in mice with acute colitis. (e) Average daily chow diet consumption in each group. Statistics of (f) colon length, (g) histological score, and (h) disease activity index (DAI) in each group. ^∗Results of three-group comparison (represented by bold line segments with endpoints). ^#,^✠, ^✟Results of the DSS group versus DSS + EA group, DSS group versus control group, and DSS + EA group versus control group, respectively (represented as thin lines without endpoints). ^∗#✠†P < 0.05; ^{∗∗##✠✠††}P < 0.01; ns: no significance. Data were presented as mean ± SEM of six mice in each group.
