title: Increased furosemide-sensitive sodium influx into erythrocytes in non-insulin-dependent diabetes mellitus associated with hypertension.
abstract: Our previous study demonstrated increased sodium (Na+) influx into ouabain-treated erythrocytes in diabetic patients with hypertension. The present study was designed to estimate the effect of furosemide on the Na+ influx in non-insulin-dependent diabetes mellitus (NIDDM) with hypertension. Both Na+ influx in the absence of furosemide (total Na+ influx; TNaI) and furosemide-sensitive Na+ influx (FSNaI) were increased in patients with essential hypertension (group 1, n = 22) than those in non-diabetic, normotensive control subjects without family history of hypertension (control group, n = 26, P less than 0.001 and P less than 0.001, respectively). TNaI and FSNaI in diabetic patients without hypertension (group 2, n = 28) were also higher than those in the control group (P less than 0.02 and P less than 0.001, respectively), but no significant differences were found in TNaI or FSNaI between groups 1 and 2. TNaI and FSNaI in diabetic patients with hypertension (group 3, n = 19) were elevated than those in control group (P less than 0.001 and P less than 0.001, respectively), in group 1 (P less than 0.05 and P less than 0.02, respectively) and in group 2 (P less than 0.001 and P less than 0.001, respectively).(ABSTRACT TRUNCATED AT 250 WORDS)
