Abstract
The activity of monoamine oxidase (MO) was studied in the liver, heart and brain of rats. The specific activity of heart was found to be 1.5 [mu]moles tyramine consumed/mg.N/hr.; that of brain 0.9, as compared to about 6.0 for liver. After a daily injection of thyroxine, triiodothyronine and triiodothyroacetic acid, on the 11th day the MO activity of liver was found to be decreased by about 50%. O-Methylthyroxine and thyroxamine caused a decrease of 30 and 25%, respectively. No significant changes in MO activity were noted in heart and brain.Keywords
