Each value represents the mean of three replicates ± SD.
Letters that differ horizontally signify a significant difference at the probability level (p ≤ 0.05), according to Duncan's test.
CV, coefficient of variation; ALP , alkaline phosphatase; ALT, alanine transaminase; AST, aspartate transaminase; IU, international unit ; LDH, lactate dehydrogenase.
