TY - JOUR AU - CHANG, HSI CHUN AB - Abstract The hypothesis that “tryptophan is the mother substance of the thyroid hormone” (Cramer, 1923,), were it true, would be very significant. Physiologically, it would settle the complex problem as to the origin, genesis, and the nature of the thyroid hormone; and clinically it would justify the trial use of tryptophan deficient diet in the treatment of exophthalmic goiter (Harries, 1923). During the last two years evidences pro or con have accumulated. This paper summarizes all facts available in order to point out where this important question stands today.
