Astaxanthin protected the cells from apoptosis of intestinal tissues in NEC rats. (a and b) The apoptotic cells of intestinal tissues in rats are stained by the TUNEL kits, and the positive cell rates were calculated in each group (magnification ×200, 400), n = 6 in each group. (c and d) The positive expression of Caspase 3 of intestinal tissues in rats was examined by immunohistochemistry (magnification ×200, 400), and the average optical density (AOD) of the Caspase 3 was calculated in each group, n = 6 in each group. ^▲P < 0.05, ^▲▲P < 0.01 vs. control group. ^★★P < 0.01 vs. NEC group.
