Fetal and maternal mannose concentrations following an eight wk maternal insulin infusion. A) The maternal-fetal arterial plasma mannose difference measured in control (n = 5), hypoglycemic (n = 5), and hypoglycemic + insulin (HG + I, n = 4).* indicates P < 0.05. Values are mean ± SEM. B) In both control (black squares, n = 5) and hypoglycemic fetal sheep (open circles, n = 5) fetal and maternal arterial plasma mannose concentrations are highly correlated in control (black squares) hypoglycemic animals (r² = 0.69, P < 0.01).
