Pterostilbene decreases diarrhea rates and improves colonic barrier function of the IUGR piglets. a The diarrhea rates of piglets; b Plasma LPS concentration; c Representative photomicrographs of hematoxylin and eosin-stained colonic sections from piglets; d Histologic scores were determined using the Chiu scoring system; e Representative photomicrographs of terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL)-stained colonic sections from piglets; f Quantitative analysis of TUNEL-positive cells in the colon; g The protein levels of colon tight junction proteins were determined by Western blot analysis. Data from at least three independent experiments were presented as mean ± SE (n = 6). ^*P < 0.05
