  1. Serum and liver PON1 enzyme activity was determined with paraoxon (Sigma–Aldrich Inc., St. Louis, MO) as the substrate essentially as described by us previously [23]. Results were expressed as IU. One unit of international enzyme activity was equal to 1 nmol of paraoxon hydrolyzed per minute per ml of serum or per g equivalent of liver microsomes
