치매와 관련된 뇌영역에 투사되는 경혈(외관(SJ5), 내관(Pe6), 삼음교(SP6) 및 현종(GB39))의 탐색에 관한 신경해부학적 연구

Neuroanatomical studies on acupoints(SJ5, Pe6, SP6 and GB39) projecting to the brain area related to dimentia using neural tracer, pseudorabies virus in mouse

Objective: The neuroanatomical studies on the acupoints(Waiguan(SJ5), Neiguan(Pe6), Sanyinjiao(SP6) and Xuanzhong(GB39)) projecting to the brain area related to dimentia using the pseudorabies virus (PRV-Ba strain) in the mouse was described. Methods: The common locations of the brain projecting to the Waiguan, Neiguan, Sanyinjiao and Xuanzhong following injection of PRV-Ba were histochemically observed. The results were as follows Results : 1. PRV-Ba labeled areas in medulla oblongata, pons and midbrain were similar to 4 acupoints, theses areas were related to autonomic center. 2. PRV-Ba labeled areas in diencephalon and cebrebrum were differently labeled according to the acupoints. 3. CNS labeled areas in Waiguan were dense labeled in CA1-3 area of hippocampus, amygdaloid nucleus, insular cortex, parietal cortex, entorhinal cortex, perirhinal cortex, dorsal endopiriform cortex, piriform cortex, amygdalopiriform transition and bed n. of stria terminalis. 4. CNS labeled areas in Neiguan were dense labeled in insular cortex, amygdaloid nucleus, parietal cortex, entorhinal cortex, perirhinal cortex, dorsal endopiriform cortex, piriform cortex, amygdalopiriform transition and bed n. of stria terminalis. 5. CNS labeled areas in Sanyinjiao were dense labeled in CA1-3 of hippocampus, suprachiasmatic n., dorsal endopiriform cortex, piriform cortex and bed n. of stria terminalis. 6. CNS labeled areas in Xuanzhong were dense labeled in suprachiasmatic n., dorsal endopiriform cortex and piriform cortex. Conclusions : Following these results, labeled acupoints in brain areas related to dimentia are Waiguan and Neiguan. Common labeled areas are amygdaloid n., entorhinal cortex, amygdaopiriform transition, bed n. stria terminalis and perirhinal cortex.
