Histological section through jejunum in group R24. Twenty-four hours reperfusion following ischemia makes the increase of NADPH-d positivity in the myenteric plexus of the jejunum compared with group R1; tunica mucosa (m), tela submucosa (sm), tunica muscularis (tm). The neurons (n) in myenteric plexus are clearly contoured and show more regular shape of their cell bodies, stained nerve fibres (thin arrows) are seen running throughout the muscular layer. The Lieberkühn's crypts (LC) are inside moderately NADPH-d stained, bordered by NADPH-d-positive nerve fibres (thick arrows). Scale bar = 40 µm.
