FIG. 3.
Microvascular blood perfusion (A) measured by CEU and fractional synthetic rate (B) in the basal state and during local insulin infusion with (SNP) or without (Control) concomitant infusion with the vasodilator, sodium nitroprusside. To provide normal reference values, previously published data (16) from a group of younger individuals (n = 7, age = 32 ± 2) undergoing the same insulin infusion protocol as the Control group are also shown. Data are the mean ± SE. *P < 0.05 versus baseline, †P < 0.05 versus Control.
