further studies are needed to define why only certain individuals respond to intravenous angiotensin ii infusions and to determine whether potentiation of angiotensin-induced thirst and vasopressin secretion by other stimuli ( e.g . hypovolaemia and hypertonicity ) might occur in man , in particular under pathological conditions when plasma angiotensin levels are above the physiological range .
