Jejunum crypt cell number (A), apoptotic index (B), and mitotic index (C) in rats subjected to distal small bowel resection (60% jejunoileal resection + cecectomy) and maintained with TPN plus GLP-2 infusion. The apoptotic and mitotic indexes are defined as the total number of apoptotic or mitotic cells, determined by a pathologist based on morphological characteristics, expressed as a percentage of the total number of cells counted in 50 well-oriented crypts. The oral group includes nonsurgical reference animals fed ad libitum. Values are means + SE. ^a,b,c,d Means with different superscripts are significantly different (P < 0.05).
