This study was undertaken to determine the hormonal responses to disabling hypothermia as a result of cold water immersion. Thermally unprotected male divers trained by the U.S. Navy were subjected to total body immersion in water at 25.5 degrees C and 33 degrees C.

It has been suggested that prolactin is a regulator of aldosterone secretion. In order to test this hypothesis, we measured prolactin, thyrotrophin and aldosterone by radioimmunoassay and plasma renin activity by the radioimmunoassay of angiotensin I in eight normal women before and after the intravenous injection of 200 microgram of thyrotrophin releasing(More)
Six patients with subacute thyroditis were followed with serial measurements of T4, FT4, TSH and RAI uptake. Five of the six underwent TRH stimulation early in the course of their illness. All six patients had elevated or high normal values for T4 and FT4 at the time of their clinical presentation (mean = 13.8 microgram per 100 ml and 3.9 ng per 100 ml,(More)
