Changes in body weight three sub-strains of C57BL/6 N mice during 7 days of DSS supplementation. a Absolute body weight comparisons between C57BL/6NKorl and other C57BL6/N mice without DSS treatment. b Relative body weight changes during DSS feeding. Male C57BL/6 N mice (8-weeks-old) were given DSS (1, 2%, or 3%) in drinking water for 7 days. Differences in the relative body weight changes between the sub-strains were not found. Each value represents the mean ± SE for six mice. Student’s t-test, ^&&&P < 0.001 vs. C57BL/6NA. ^###P < 0.001 vs. C57BL/6NB
