Administration of ML-7 reduced the histopathological score, and inhibited the epithelial permeability rise in IO rats. Intestinal tissues of sham and IO rats treated with vehicle (v) or ML-7 were graded for histological damage (A), or mounted on Ussing chambers for the measurement of electrical conductance (B) and mucosal-to-serosal HRP fluxes (C). n = 5-7/group. *p < 0.05 vs. sham rats. #p < 0.05 vs. IO+v rats.
