초록
The etiologic role of renin-angiotensin system and sodium-volume status in the pathophysiology of various forms of hypertension was investigated. Plasma renin activity (PRA) was measured by radioimmunoassay, while sodium-volume status was evaluated by the determination of total exchangeable sodium(NaE) using isotope dilution method. The subjects consisted of 25 controls, 24 patients with essential hypertension, with chronic renal failure (13 with hypertension, 9 without hypertension) and with malignant hypertension. The results were as follows: 1. An inverse correlation between NaE and PRA was noted in control subjects (r=-0.598, p<0.001) and normal renin essential hypertension(r=-0.551, p<0.05) and the chronic renal failure with hypertension. (r=-0.790, p<0.001) 2. NaE increased markedly the in chronic renal failure with hypertension (
$50.1{\pm}7.24mEq$) as well as in its renin subgroups.(p>0.1) 3. Absolute value of PRA was not deviated significantly from control group (
