Ameliorating Iron Overload in Intestinal Tissue of Adult Male Rats: Quercetin vs Deferoxamine

Figure 3

Immunohistochemical staining micrographs of intestinal tissues (duodenum and ileum) of the studied groups for Caspase 3 reactivity (arrow). A, A1: Control group section shows few weak Caspase-positive cells. B, B1: iron overload group section shows numerous strongly positive cells. C, C1: Iron +DFO group section shows decrease of caspase-3 reactivity. D, D1: Iron+ Quercetin group section shows that marked reduction of the Caspase reactivity in most cells or few strong positive cells is detected (immunoperoxidase, haematoxylin counter-stain x200).
