    In four individuals, continuous glucagon during basal and hyperinsulinemic periods increased hepatic glucose production suppression versus basal-period glucagon alone: 63 versus 52%.

    In plain wordsIn four individuals, continuous glucagon increased suppression of liver glucose production compared with glucagon during the basal period only.

    Summary
    in four additional individuals HGP was suppressed to a greater extent during a tolbutamide infusion when glucagon was administered continuously throughout the basal and hyperinsulinemic periods than when glucagon was infused during the basal period only; HGP suppressed by 63 +/- 3 vs. 52 +/- 3%, res…

    Summary · context
    To further examine whether glucagon was enhancing the effect of portal insulin, in four additional individuals HGP was suppressed to a greater extent during a tolbutamide infusion when glucagon was administered continuously throughout the basal and hyperinsulinemic periods than when glucagon was inf…
