(A) Fasting plasma glucose. (B) Fasting plasma insulin. (C) Glucagon. (D) Ra glucose in control and STZ/HFF rats. (E) Rates of hepatic glucose production vs. plasma glucose concentration, including data from the very diabetic STZ/HFF rats. *, P < 0.05 vs. control; †, P < 0.01 vs. HFF; ‡, P < 0.001 vs. control, §, P < 0.01 vs. STZ.
