Ultrastructure of the duodenum epithelium in a C group (A), LD (B, C) and HD group (D, E, F). A Note numerous, long, regularly arranged microvilli on the apical surface and numerous mitochondria with a moderate electron density of the matrix in the upper part of absorptive cells. C, E Note shortage of microvilli (arrows), loss of microvilli (asterisks), protrusions on the apical surface of endothelial cells (arrow heads) and swollen mitochondria (double arrows). B, D. Epithelium covered by a thick layer of mucus. A lack of microvilli (asterisks) and damage of epithelial cells (arrows). F. Damaged cells in the area covered by a thick mucus layer
