The serum levels of thyrotropin (TSH) increased two minutes after a quick single iv. injection of 800 μg of synthetic thyrotropin releasing hormone (TRH) into a normal male subject. The peak elevation of TSH occurred after 30 minutes, and was 370% higher than the level at 0 time; after 3 hours, the level decreased to normal. The levels of GH, LH, and FSH did not significantly change, but the plasma level of cortisol rose slightly. These studies show the hormonal activity and specificity of synthetic TRH to release TSH in man and indicate its future use for studying the pituitary-thyroid system of man in health and disease.
