GT and Q reduced the risk of liver damage in enhancing the therapeutic effect of Doc. The liver condition was evaluated with both blood level of liver enzymes and liver pathological examination. Eight blood and liver samples were randomly selected from each group for this analysis. The blood alanine transaminase (ALT) level was determined by measuring its colorimetric product pyruvate using assay kit (a). Data are presented as mean ± SD. For the liver pathological examination, a section of liver tissue was fixed in 10 % phosphate buffered formalin and paraffin-embedded. Slides were cut and stained with H&E. The liver condition was graded based on the degree of inflammation, piecemeal or bridging necrosis, and representative images from each group were presented (b)
