Figure 2. Characterization of CLP-induced sepsis in rats. Serum and tissue samples from rats with untreated CLP-induced sepsis, rats with Tri A–treated CLP sepsis, or healthy control rats. (A) Lung tissue from the control group of rats; (B) lung tissue from rats with CLP-induced sepsis; (C) lung injury index; (D) ALT activity; (E) AST activity; (F) creatinine concentration; and (G) BUN levels in the plasma from healthy control rats and CLP-induced sepsis rats. Results are expressed as the mean ± SEM. *P < 0.05; **P < 0.01; ***P < 0.001.
