The values are means±SD (n = 10) of triplicate groups.
Means in each group of parameters with the same superscript letter are not significantly different (p>0.05).
*
Indicates significant differences between the two groups at equivalent weeks (p<0.05).
ALT = Alanine aminotransferase; AST = Aspartate aminotransferase.
