Levels of serum alanine aminotransferase (ALT) after CCl
. Serum levels of ALT peak 2 days following CCl4 administration in mice of all genotypes. Thereafter, the values return to basal levels within 7 to 14 days in a similar manner in all experimental groups (n = 3–8 at each time point). * P = 0.023 when compared experimental controls.
