Correlation between serum osmolality and AVP concentration in 8 young and 8 older subjects during a 2-hour 3% saline infusion following mild dehydration. The older subjects had significantly higher plasma levels of AVP per unit increase in plasma osmolality, strongly suggesting an enhanced osmotically-stimulated secretion. (From Helderman JH. The response of arginine vasopressin to intravenous ethanol and hypertonic saline in man: The impact of aging. J Gerontol 1978;33(1):39-47)
