A Liver enzymes activity, alkaline phosphatase (ALP) and lactate dehydrogenase (LDH). B Lipid profile, cholesterol, TG, LDL, and HDL. Data were expressed as Mean ± SEM. Values with a different letter superscript are significantly different between groups. Asterisks indicate levels of significance (ANOVA with post hoc Tukey test, *P < 0.05; **P < 0.01; ***P < 0.001)
