Photomicrographs of liver sections from control and treated groups, stained with hematoxylin and eosin H&E (10X). Liver section of control group showing, the hepatic cords (HC), sinusoids (S) that radically arranged around central vein (C.V.) (a). Liver section of AlCl3-treated group showing, massive infiltration (M.F.), cell degeneration (arrow) and nuclear pyknosis (P) (b). Liver section of propolis- treated group showing, normal hepatic cords (HC), sinusoids (S), central vein (C.V.) and normal nuclei (N) (c). Liver section of AlCl3 + propolis treated group showing disappearance of inflammatory infiltration, recovered cell degeneration and little abundance of nuclear pyknosis (P) (d). Liver section of the AlCl3 treatment for one month followed by administration of AlCl3 combined with propolis for another month group showing improvement of cell degeneration with marked nuclear pyknosis (P) (e)
