Figure 3: Photomicrograph of the MT× / water treated group showing that the MT× caused mucosal damage in the jejunum. It causes loss or blunting and fusion of villi, heavy infiltration of inflammatory cells and lack of recognizable goblet cells along the crypt-villus a×is of the small intestine. Loss of surface epithelium and marked e×foliation of the villi and crypt necrosis (A1, H&E×100; A2, H&E×400). The MT× / water treated group showed negative immuno reactivity to ki-67 and Bcl-2 (A3, immunohistochemistry ×400; A4, immunohistochemistry ×400 resp ectively). The congestion of blood vessels were most severe in the MT× / water treated group (arrows).
