Table 3. Glucose kinetics during leucine flux measurementsa

GroupPlasma Glucose (mg/dl)Plasma Insulin (μU/ml)Glucose Disposal Rate (mg/kg/min)
a Glucose disposal, the amount of glucose infused to maintain plasma glucose at basal level. B-HD, HD, and N represent, respectively, predialysis, hemodialysis patients, and normal subjects. All P values listed were derived from one-way ANOVA comparing the three study groups within the same flux.
b P < 0.05 B-HD versus N.
c P < 0.5 HD versus N.
