Figure 2. Effect of antrodan on lipopolysaccharide (LPS)-induced serum glutamine-oxaloacetic transaminase (GOT) (A), glutamic-pyruvic transaminase (GPT) (B), interleukin (IL)-6 (C) and nitric oxide (NO) (D) levels. Con, control; LPS, 5 mg/kg LPS; Antrodan, 40 mg/kg antrodan; Antrodan L+LPS, 40 mg/kg antrodan + LPS; Antrodan H+LPS: 80 mg/kg antrodan + LPS. Values are expressed as the mean ± S.D. (n = 6). One way ANOVA is followed by the post-hoc LSD test. Different letters indicate a significant difference (p<0.05).

(A) Superoxide dismutase, (B) catalase, (C) glutathione peroxidase (GSH-Px), and (D) thiobarbituric acid reactive substances (TBARS). Con, control; LPS, 5 mg/kg LPS; Antrodan, 40 mg/kg antrodan; Antrodan L+LPS, 40 mg/kg antrodan + LPS; Antrodan H+LPS, 80 mg/kg antrodan + LPS. Values are expressed as the mean ± S.D. (n = 6).

Figure 4. H&E staining of liver tissues. (A) Control; (B) tissue treated with 5 mg/kg (i.p.) lipopolysaccharide (LPS) showing severe inflammatory cell infiltration and markedly diffuse cellular infiltration, and vacuolar degeneration in some hepatocytes; (C) treated with 40 mg/kg antrodan; (D) pretreated with 40 mg/kg antrodan by gavage and then with LPS, showing focal areas of liver parenchyma with neutrophil infiltration and necrosis; (E) animal pretreated with 80 mg/kg antrodan by gavage and then with LPS, showing no pathological changes except for a few neutrophils in the sinusoids. Antrodan at 40 mg/kg was revealed to be hepatoprotective against the inflammatory abuse by LPS. (magnification, all 200×).

Figure 5. Effect of antrodan on the activation of cytoplasmic NF-κB (p65) protein and the expression of iNOS in lipopolysaccharide (LPS)-stimulated rat liver tissue by Western blot analysis. Con, control; LPS, 5 mg/kg LPS; Antrodan, 40 mg/kg antrodan; Antrodan L+LPS, 40 mg/kg antrodan + LPS; Antrodan H+LPS, 80 mg/kg antrodan + LPS. Values are expressed as the mean ± S.D. (n = 6). One way ANOVA is followed by the post-hoc LSD test. Different letters indicate a significant difference (p<0.05).
