Central Localization of the Neurons Projecting to the Kidney, UB23 and GB25 Using the Pseudorabies Virus

Objective : To investigate the relation to the organs, shu points and mu points. The labeled common locations of the spinal cord and brain were observed following injection of pseudorabies virus(PRV) into the the kidney, UB23 and GB25. Methods : After survival times of 96 hours following injection of PRV, The fifteen rats were perfused, and their spinal cord and brain were frozen sectioned($30{\mu}m$). These sections were stained by PRV immunohistochemical staining method, and observed with light microscope. Results : In spinal cord, PRV labeled neurons projecting to the kidney, BL23 and GB25 were founded in cervical, thoracic, lumbar and sacral spinal segments. Dense labeled areas of cervical segments were overlap in lateral cervical n. and lamina III-V area. Thoracic segments were overlap in lateral spinal n., intermediolateral n. and lamina V-X areas. Lumbar segments were overlap in lamina I-V areas. Sacral segments were overlap in lamina IV, V and X areas. In brain, PRV labeled areas projecting to the kidney, UB23 and GB25 were overlap in the A1 noradrenalin cells/C1 adrenalin cells/caudoventrolateral reticular n./rostroventrolaterai n., raphe obscurus n,, raphe pallidus n., raphe magnus n., gigantocellular reticular n., locus coeruleus, subcoeruleus n., A5 cell group and paraventricular hypothalamic n.. Conclusions : This results suggest that PRV labeled overlap areas of projecting to the kidney may be correlated to shu and mu points related to the kidney. These morphological results provide that organs-shu(transport) and mu(alarm) points interrelationship may be related to the central autonomic pathways.
