Fig. 5.

Electron micrograph shows the status of the mucosal lining with signs of incomplete cellular recovery with signs of non-efficacious renewal in the group treated with NTZ. Some nuclei with euchromatin are seen in A (red arrows), still with an irregular basal distribution. Other nuclei, rich in heterochromatin (N.H), are still seen in A (blue arrows), C & D, as well as abnormal swollen mitochondria with areas of degenerated damaged microvilli in B. Cytoplasmic vacuolation is seen in C. C; Other areas with apparently healthy microvilli, yet with few abnormal cytoplasmic mitochondria and dense granules (Scale bar; 2 μm in A, 500 nm in C&D and 100 nm in B and).
