Effect of SeY on apoptosis rate in intestinal epithelial cells. (a) Evaluation of jejunal cell apoptosis by flow cytometry in weaned pigs exposed to SeY and diquat challenged. 30,000 cells were used in each acquisition reading. Frames were divided into 4 quadrants: Q1-UL represents necrotic cells; Q1-UR represents late apoptotic and early necrotic cells; Q1-LR represents early apoptotic cells; and Q1-LL represents normal cells; percentages of apoptotic cells of early apoptosis (b), late apoptosis (c), and total apoptosis (d) in the jejunum, respectively. ^a,b,cMean values with different letters on vertical bars indicate significant differences (P < 0.05). CON: pigs were fed with basal diet and challenged by sterile saline; SSY: pigs were fed with SeY-containing diet and challenged by sterile saline; DT: pigs were fed with basal diet and challenged by diquat; DSY: pigs were fed with SeY-containing diet and challenged by diquat.
