Figure 2 Liver hydroxyproline (A); HA (B) and LN (C) content of the TAA rats treated with tetrandrine. T-5: treated with 5 mg/kg tetrandrine; T-10: treated with 10 mg/kg tetrandrine; T-20: treated with 20 mg/kg tetrandrin; IFN: treated with interferon-г 5 × 10⁴ U. Results represent the mean ± SD. ^aP < 0.05; ^bP < 0.01; ^dP < 0.001, vs control group.
