1. The pattern of monoamine oxidase (MAO) activity is comparable in rat, turkey and chicken tissues, with the liver having the highest activity, followed by the kidney and then the heart. 2. Catechol-O-methyl transferase (COMT) has no definite pattern of activity in the organs of the two avian species studied, and is markedly lower as compared to that of the rat. 3. Cardiac and hepatic MAO levels increase, whereas COMT activities remain low with advancing age in the turkey. 4. MAO but not COMT inhibition potentiates the cardio-vascular responses to administered norepinephrine in the turkey.
