HAI, rat liver histopathology; CTRL, normal control rats; PS, porcine serum-induced fibrotic rats treated with saline; PS + pcDNA3, porcine serum-induced fibrotic rats treated with pcDNA3; PS + pcDNA3-rIL-10, porcine serum-induced fibrotic rats treated with pcDNA3-rIL-10. Grading of inflammation:

^aP<0.01, compared to group CTRL;

^bP<0.01, compared to groups PS and PS + pcDNA3. Staging of fibrosis:

^cP<0.01, compared to group CTRL;

^dP<0.01, compared to groups PS and PS + pcDNA3.
