Abstract

Histochemical characterization of NADPH-d positive structures in the rabbit spinal cord during the normal and ischaemic conditions was performed. Strongly enhanced staining of NADPH-d positive neurons and their processes appeared in the superficial dorsal horn (laminae I-III), the pericentral region (lamina X) and mainly in neurons of the sacral parasympathetic nucleus at the end of 40 min of abdominal aorta ligation. These findings suggest that ischaemia causes increased production of NADPH-d/NOS enzyme in the lumbosacral spinal cord of the rabbit.

 

Key words: rabbit spinal cord, NADPH-d histochemistry, ischaemia.
