Change of the nicotinamide methylpherase activity of a rat liver in the state of tumor growth was studied. In the liver of tumor-bearing rat, nicotinamide methylpherase activity increased with the growth of the tumor. This increase is caused by various factors, such as the nutritional state of the host, hypophyseal and adrenocortical hormone. Toxohormone also has some effect on the change of nicotinamide methylpherase activity.
