Abstract:
Objective To investigate the derivation and distribution of nitric oxide synthase (NOS) and its relation with the microvessels in the spinal cord. Methods The microscopic features and ultrastructure of NOS in the spinal cord tissue of rats were observed by immunohistochemistry and immunoelectronmicroscopy. Results NOS immunoreactive interneurons were identified mainly in the intermediolateral cell column, around the central canal and in the dorsal and ventral horn, and many of the NOS-containing neural processes and neurons were closely associated with the spinal cord microvessels. Conclusion The regional distribution of NOS may be indicative of the involvement of nitric oxide (NO) in different function related to movement, sensory processing and visceral regulation, and the ultrastructural features benefit the NO diffusion into the microvessels to regulate the blood flow in the spinal cord.
