The HXF eased nano NiO-induced PF in the rats. (A1–A4) Collagen deposition in the control group, nano NiO group, nano NiO + 500 mg/kg HXF group, nano NiO + 1000 mg/kg HXF group by Masson staining, respectively (n = 3). (B) Semiquantitative analysis of collagen deposition. (C) Col-I protein bands. (D) Semiquantitative analysis of Col-I protein levels (n = 5). Values are expressed as mean ± SD. * The nano NiO group versus the control group, # nano NiO + HXF groups versus the nano NiO group (p < 0.05).
