The number of animals for different experimental groups and various parameters at 8 h after the termination of LPS infusion.

Sham, sham group; Sch, sch alone group; LPS, LPS infusion for 90 min group; Sch 1.25 + LPS, Sch 2.5 + LPS, and Sch 5 + LPS represent Sch pretreatment at 1.25, 2.5, and 5 mg/kg/h followed by LPS infusion for 90 min group, respectively. The same rat was used for assessment of wet-to-dry weight ratio, histology and immunohistochemistry, MPO activity assay and Western blotting. Number in parentheses means the same rats were used as the upper row.
