Abstract

Objectives : The purpose of this morphological studies was to investigate the relations between Sanyinjiao(Sp6), Yinlingquan(Sp9) and pancreas of rats using peudorabies virus(PRV). Methods : We observed labeled neurons following the injection of PRV, Bartha strain, into the Sanyinjiao(Sp6), Yinlingquan(Sp9) and pancreas of rats. After survival times of 4 days following the injection of PRV, the rats were perfused, and their spinal ganglia, spinal cord and brain stem were frozen sectioned($35{\mu}m$). These sections were strained by PRV immunohistchemical staining methods and observed with light microscope. Results : The results were as follows. 1. In the spinal ganglia, the overlap areas of PRV labeled neurons projecting to Sanyinjiao(Sp6), Yinlingquan(Sp9) and pancreas were observed in T10-13 dorsal root ganglia. 2. In the spinal cord, the overlap areas of PRV labeled neurons projecting to Sanyinjiao(Sp6), Yinlingquan(Sp9) and pancreas were lamina I, IV, V, VII, IX, X, intermediolateral nucleus(IML), intermediomedial nucleus(IMM) in thoracic segments. In lumbar segments, the overlap areas of PRV labeled neuron were lamina I, IV, V, VI, IX, X and IMM. In sacral segments, the overlap areas of PRV labeled neuron were lamina I, IV, V, VI, VII, IX, X. 3. In the brain, the overlap areas of PRV labeled neurons projecting to Sanyinjiao(Sp6), Yinlingquan(Sp9) and pancreas were area postrema, nucleus tractus solitarius, caudoventrolateral reticular nu., medullary reticular nu., lateral paragigantocellular nu., C3 adrenalin cells, gigantocellular nu., raphe pallidus nu., raphe obscurus nu., ambiguus nu., raphe magnus nu., pontine reticular formation, A5 cell group, subcoeruleus nu., locus coeruleus, Barringnton's nu., $K{\ddot{o}}lliker$-Fuse nu., dorsal raphe nu., Edinger-Westphal nu., central gray matter, perifornical nu., dorsomedial hypothalamic nu., arcuate nu., lateral hypothalamic nu., paraventricular hypothalamic nu., hindlimb area. Conclusions : In conclusion, these results suggest that the interrelationship of meridian(spleen meridian), acupoints(Sp6 and Sp9) and viscera(pancreas) may be related the central autonomic centers.
