Fluorescence emission in enteral nutrition residues from resected stomachs of mice at 60 min after ingestion. A. Representative images of fluorescence values derived from gastric contents of mice that were given liquid EN bolus containing fluorescent imaging agent without (a) or with (b) pectin. Fluorescence emission on Y-axis as indicates gastric residues of enteral nutrition. Values from mice (n = 8 per group) without (unfilled bars) and with (filled bars) pectin are shown as means ± SD. *p < 0.05 (Student’s t test). B. Regression analysis of fluorescence emitted by enteral nutrition residues with (filled circles) and without (unfilled circles) pectin in resected stomachs vs. stomachs imaged at 60 min after ingestion in vivo.
