Changes of Serum Angiotensin-Converting Enzyme Activity During Treatment of Patients with Graves’ Disease *

摘要

Serum angiotensin-converting enzyme activity was measured spectrophotometrically, and serum thyrotropin-binding-inhibitory immunoglobulin (TBII) activity was measured by radioreceptor assay in normal subjects and in patients with Graves’ disease serially before and during treatment, and these activities were compared with each other and with thyroid hormone levels in various thyroid functional status. Correlation between serum angiotensin-converting enzyme activity and serum thyroid hormone level was pursued with relation to the changes of thyroid functional status in patients with Graves’ disease during treatment.
