When the 12 g/kg, 24 g/kg, and 48 g/kg DCHD treatment could decrease ALT, AST, ALP, γ-GT, TC, TBA, TBIL, and DBIL levels in the BDL-induced extrahepatic cholestasis model, the depressed effect of DCHD on ALT and AST levels positively correlated with the administration dose (Figure 2C). Here, GPT is linked to extrahepatic cholestasis.
