Nitric oxide may prevent hypertension early in diabetes by counteracting renal actions of superoxide.


The dependence of blood pressure on a balance between superoxide and nitric oxide may be amplified in diabetes. We have shown that the first occurrence of sustained hyperglycemia in type I diabetes causes hypertension when induced in rats that have had nitric oxide synthesis blocked chronically (L-NAME, 10 microg/kg per minute IV). This study used tempol… (More)
