ALT (U/mL)	19.22 ± 0.70^a	13.05 ± 0.62^b	14.53 ± 0.81^b	15.63 ± 0.63^b
AST (U/mL)	11.55 ± 0.76^a	10.42 ± 0.63^ab	8.47 ± 0.34^b	9.19 ± 0.24^b
ALP (U/mL)	25.2 ± 0.70^a	19.9 ± 0.65^b	16.7 ± 0.72^b	17.5 ± 0.63^b

Control or TG1 (untreated), TG2 (0.5% TGO), TG3 (1% TGO), and TG4 (2% TGO). ALT, alanine aminotransferase; AST, aspartate aminotransferase; and ALP, alkaline phosphatase. Different letters (a–b) in the same row indicate significant differences ().
