THE CORRELATION OF CENTRAL AFFERENT OF ACUPOINTS QUANLIAO(SI 18) AND SHIBAI(ST 2): TRANSGANGLIONIC DEGENERATIVE METHOD STUDY

Using transganglionic degenerative methed, we investigated the primary afferentinformation of acupoints of Quanliao (SI 18) and Shibai(ST 2). The results showed that the largeamounts of degenerative fibers could be found bilaterally in trigeminal spinal nucleus and its tract,trigeminal principal sensory nucleus, trigeminal mesencephalic nucleus and some degenerations couldbe observed ipsilaterally in solitary tract and its nucleus, medullary lateral reticular nucleus, giganto-cellular reticular nucleus and nucleus raphe magnus following transection of infraorbital nerve. A verymoderate degenerative fibers could be identifed in ipsilateral accessory spinal nucleus and spinal reticu-lar nucleus. A few degenerative fibers were seen on the contralateral magnocellular part of caudatepart of trigeminal spinal nucleus by passing through the posterior commissure of canalis centralis.These results suggest that the primary information of acupoints of Quanliao and Shibai could be trans-mittered into the above struc

THE CORRELATION OF CENTRAL AFFERENT OF ACUPOINTS QUANLIAO(SI 18) AND SHIBAI(ST 2) : TRANSGANGLIONIC DEGENERATIVE METHOD STUDY

Using transganglionic degenerative method, we investigated the primary afferent information of acupoints of Quanliao (SI 18) and Shiba(ST 2). The results showed that the large amounts of degenerative fibers could be found bilaterally in trigeminal spinal nucleus and its tract, trigeminal principal sensory nucleus, trigeminal mesencephalic nucleus and some degenerations could be observed ipsilaterally in solitary tract and its nucleus, medullary lateral reticular nucleus, giganto-cellular reticular nucleus and nucleus raphe magnus following transection of infraorbital nerve. A very moderate degenerative fibers could be identified in ipsilateral accessory spinal nucleus and spinal reticular nucleus. A few degenerative fibers were seen on the contralateral magnocellular part of caudate part of trigeminal spinal nucleus by passing through the posterior commissure of canalis centralis. These results suggest that the primary information of acupoints of Quanliao and Shibai could be trans-mittered into the above structures to regulate pain information and to fulfill the effect acupuncture analgesia. Our research provided a morphological basis for understanding further the effect of facial acupuncture produced analgesia.
