Change of intestinal permeability in mice after treatment with TiO2 and lipopolysaccharides (LPS). The levels of LPS (a), diamine oxidase (DAO) activity (b) and D-lactate (c) in mice serum after mice being fed with TiO2 NPs or TiO2 MPs-mixed feed for 1, 3, and 6 months and following gavage with LPS (mean ± SD, n =4). Significant differences between two groups (*p< 0.05, **p< 0.01)
