[THE EFFECT OF POSTURAL CHANGES ON THE PHYSIOLOGICAL FUNCTION IN MAN].

Abstract

same level. Urinary output of catecholamine, particularly of noradrenaline, increased markedly. The increased noradrenaline excretion may be attributed to the vasoconstriction, which was inferred from the reduction of amplitude in volume pulse in the big toe and from the fall in skin temperature. The rise of rectal temperature on tilting from recumbency to tilt position may be attributed to both the decrease of heat loss through vasoconstriction and the increase of heat production. On tilting urine volume and urinary output of sodium and chloride decreased, while little change was observed in potassium excretion.
