Figure 3: HE-Bu from E. uniflora inhibits iNOS (b) and COX-2 (c) expression in ileum of infected mice. Mice were treated with HE-Bu 75, 150, or 300 mg·kg−1, p.o. or dexamethasone. The levels of iNOS and COX-2 were determined by western blot analysis. Representative immunoblots (a). Results are shown as the means ± SEM of 2 to 3 different experiments. ###, CLP plus vehicle versus sham. ** and ***, HE-Bu versus vehicle.
