Contents of factors in mice after 1-week TCS exposure. (A) The proteinlevels of cytokines in colon tissues examined by ELISA (n = 12/ group). (B) the protein levels of cytokines in colon tissues examined by Western blot and were normalized relative to the β-actin (n = 3/group). (C)Representative pictures for Western blot runs. According to the sizes of the target bands and comparisons with marker, the target bands were cut out from polyacrylamide.(D) Plasma concentration of cytokines examined by ELISA (n = 12/group). The results are expressed as means ± SD. *P < 0.05. The statistical significance of two groups was determined using Student’s t test
