CK inhibits the NF-κB activation in DSS-induced colitis in mice.

<p>Representative images of IHC staining of NF-κB (p65) and IκB-α in mild colitis and severe colitis. (A) The expression of NF-κB (p65). (B) The expression of IκB-α. Software used 20 images. Three animals were analyzed for each type of mice. (C) Quantification of NF-κB (p65) positive density in each group. (D) Quantification of IκB-α positive density in each group (n = 3). # <i>p<</i>0.05, ## <i>p<</i>0.01 compared with the control group. *<i>p</i> compared with DSS4D3DR or DSS7D3DR group. *<i>p</i><0.05, **<i>p</i><0.01.
