Figure 5: Effect of corn oil (C/oil), vitamin C (VC) and/or co-administration of chlorpyrifos (CPF) and lead (Pb) on some serum enzyme concentrations in Wistar rats. abP<0.05 versus C/oil and VC groups, respectively; cdP<0.01 versus C/oil and VC groups, respectively; eP<0.05 versus VC+CPF+Pb group; fP<0.01 versus VC+CPF+Pb group. Aspartate transferase (AST), alanine transferase (ALT), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT), lactate dehydrogenase (LDH).
