Figure 4.

Histological section through jejunum in the group R30. The NADPH-d positivity in the myenteric plexus of jejunum after ischemia and 30 d reperfusion is seen with no differences in NADPH-d positivity compared with K group; tunica mucosa (m), tela submucosa (sm), tunica muscularis (tm). NADPH-d activity is present mainly in numerous ganglion cells (n) and nerve fibres (thin arrows) in the tunica muscularis and is also visible in the Lieberkühn's crypts (LC), which are bordered by the NADPH-d-positive nerve fibres (thick arrows). Scale bar = 40 µm.
