Effects of i.v. infusion of d-glucose (A), mannitol (B), i.c.v. injection of d-glucose (3 μmol (3 μl)⁻¹) (C) and l-glucose (3 μmol (3 μl)⁻¹) (D) on gastric distension-induced pyloric relaxation. i.v. infusion of d-glucose and i.c.v. injection of d-glucose significantly reduced gastric distension-induced pyloric relaxation (E) (n = 5, ** P < 0.01 by paired t test). i.c.v. injection of d-glucose and l-glucose were applied 30 min before gastric distension. The bars beneath the traces indicate balloon distension (2 ml). BS, blood sugar.
