Ultrastructure of the duodenum epithelium covered a thick mucus layer in the HD group. A Note swollen mitochondria (arrows) and numerous vesicles in the cytoplasm of damaged cells. B A lack of epithelium continuity (asterisk). C Area with a complete loss of epithelial cells. Note that the lamina propria is separated from the mucous by the basement membrane (arrows, insert—a part of the image at higher magnification). Double arrows show a break in the basement membrane
