Studies on human iodide peroxidase: its activity in various thyroid disorders.
Iodide peroxidase activities in the human thyroid gland were measured in various thyroid disorders. The peroxidase activities in the thyroid gland revealed high values in Graves' disease, normal levels in thyroid adenoma and low values in thyroid carcinoma as compared to those in normal thyroid glands. A high activity of this enzyme was observed in toxic adenoma. The same results were observed whether 10% (W/V) homogenate or mitochondrial and microsomal fractions of the thyroid gland were used.
