Liver immunohistochemistry: (A) Sirius Red, (B) CD3, (C) Ki67, and (D) Cytokeratin 7 (CK-7). Objective histology scoring was performed, and a Mann-Whitney U test was conducted to determine P-value. All tests were 2-sided using a significance level of 0.05. Note that there were no differences in hepatic fibrosis, Ki67, CD3, or CK-7 immunostaining (see arrows) between the groups.
