Addition of thiouracil to a high tyrosine diet alleviated signs of tyrosine toxicity in the rat, whereas, daily injections of thyroxine aggravated them. Plasma tyrosine concentration and liver tyrosine transaminase activity were high in rats fed a high tyrosine diet; thyroxine administration increased them further, but depressed slightly the activity of liver p-hydroxyphenylpyruvate hydroxylase.
