The Protein-Bound Plasma Iodine in Patients with Thyroid Disease

Abstract

Studies on 32 patients with and without thyroid disease have disclosed that the basal heat production is directly proportional to the log of the protein-bound plasma I, according to the . expression basal heat production = 52.3 log (I)[long dash]0.8 calories/ square meter/hr. This relationship is valid after lugoliza-tion and after thyroidectomy. However, for about 24 hrs. immediately after surgery there is a temporary rise in plasma protein-bound I that is not reflected by a rise in the basal heat production.
