Note. Distal small intestinal tissues from sham and IO rats treated with vehicle (labeled 'sham+v' and 'IO+v') or a MLCK inhibitor, ML-7 (labeled 'sham+ML-7' and 'IO+ML-7') were processed for histological examination. n = 6-7 rats per group. Values were expressed as mean ± SEM. *p < 0.05 vs. respective sham groups. #p < 0.05 vs. IO+v rats.
