A: Intestinal epithelium from normal mouse. HRP administered intralumenally (il). Label can be seen to penetrate a short distance (zonula occludens) between epithelial cells. B: Intestine from a mouse hemorrhaged and fed vehicle. HRP administered il. Large amounts of label penetrate between the epithelial cells. C: Intestine from a mouse hemorrhaged and fed IL-6. HRP administered il. Label is scant between cells.
