Viscosity of enteral nutrition mixed with artificial gastric juice and schema of experimental design. A. Effect of shear rate on viscosity measurements of EN with (filled circles) and without (unfilled circles) pectin mixed with equal amount of artificial gastric juice. B. Schema of experimental design. Mice fasted for 24 hrs were injected with 10 μL/g body weight of enteral nutrition (0 min; ▲) 2 h after withdrawing drinking water (■). Gastric imaging proceeded 5, 15, 30, 45, 60 minutes after injection under isoflurane anesthesia (●). Isolated stomachs were assessed thereafter (◇).
