The hepatic lesion scores of different groups. The scoring criteria: 0 = normal hepatic tissue; 1 = mild lesions (including congestion, lymphocyte infiltration, hepatocyte regeneration); 2 = severe inflammatory lesions (including steatosis, amyloidosis, necrosis); and 3 = hepatic lymphosarcoma; data are presented as means ± SD; different letters on the bars of two groups mean statistically significant difference between them (P < 0.05) and same letters mean no significant difference (P > 0.05).
