RESUMO
The Research Committee for the Meridian Point held its third workshop at the 57th Annual Meeting of the Japan Society Acupuncture and Moxibustion in Kyoto. Evaluations and reports were presented on two topics.<BR><BR>The first topic:Study of PSC in Japan and China.<BR> 1) Literature search on PSC in China (Wang):A literature search on major studies on PSC in China since 1979 was conducted. The report introduces the definition, characteristics and the mechanism of PSC development together with meridian phenomena.<BR><BR> 2) PSC in reference to the ryodoraku (Morikawa):Development of the reactive ryodo point in patients under hemodialysis or those who have had a total gastrectomy and the cases in which reactive ryodo points or needle sensation developed when specific regions were stimulated were reported. The relationship between reactive ryodo points and PSC was examined. <BR><BR> 3) The mechanism by which PSC develops (Yamada):Neurotransmitter substances are released from sensory nerve endings during acupuncture stimulation. Absorbed by lymphatic vessels, these substances stimulate the smooth muscle of these vessels, thus causing the PSC. Based on factors such as transmission velocity and inhibitory factors, the mechanism by which PSC develops was investigated.<BR><BR>The second topic:Specific locations of meridian points and clinical effects of the meridian point.<BR> 1) Anatomical regions for GB 30 huantiao (Ozaki and Matsuoka):In establishing the international standard for the meridian points under the guidance of WHO, both Chinese and Japanese proposals were listed for GB 30. The clinical effects-presumably emanating from the subcutaneous structure when acupuncture stimuli are applied to these points in a direction perpendicular to the body surface-were comparatively evaluated. <BR><BR> 2) Transition in the regions and main effects of GB 30 (Sakaguchi):As stated above, both Japanese and Chinese definitions were cited in establishing the international standard for GB 30 under the guidance of WHO. By quoting the classic literature from China and Japan, changes in the regions and main effects of GB 30 were comparatively evaluated.
RESUMO
Six members of the Research Committee for the Meridian Point (former Committee for the Meridian Point) reported on three themes regarding meridian and acupuncture point at Workshop II of the 54th Science Rally of The Japan Society of Acupuncture and Moxibustion held in Fukuoka.<BR>1st theme : Anatomical examination of the meridian and meridian point.<BR>1) Anatomic structure showing path and meridian running. (Kenji Matsuoka) : Similarity of meridian pathway and course of nerve and blood vessels in cadaver.<BR>2) Gross anatomical study of meridian and acupuncture point in upper limbs (Kansho Yamada) : Doctoral study of Katsuyosi Toyoda, former Nagoya City University School of Medicine researcher and Yamada's study (Relation between running of meridian & acupuncture point and subdermal nerve & blood vessels) were reported.<BR>2nd theme : Study of acupuncture safety depth in Japan and China.<BR>1) Research and progress situation of acupuncture safety depth in China. (WANG Cai Yuan) : Data of Yan Zhenguo, professor of anatomy at Shanghai University of Traditional Chinese Medicine, an authority on the study of acupuncture safety depth and progress situation of recent study of acupuncture safety depth in China.<BR>2) Retrospective study of acupuncture safety depth (Tomofumi Ozaki) : Study of acupuncture safety depth published by Ozaki to date and comparative study alongside Prof. Yan Zhenguo data.<BR>3rd theme : Examination of clinical effect of a few meridian points.<BR>1) Acupuncture clinical effect using a few meridian points (Syunji Sakaguchi) : Paper research and analysis of acupuncture clinical effects using 1-4 meridian points of Japana Centra Revuo Medicina.<BR>2) Inflence on skin energizing current by various acupuncture stimulation of LI4 (Gokoku) (Kazuhiro Morikawa) : Influence on the amount of skin energizing current by acupuncture stimulation, direct current electricity stimulation and stimulation of electroacupuncture to LI4.
RESUMO
The Committee for the Meridian Point (Chairman, Kansho Yamada) focused on the significance of “the Meridian denial theory” which Hirohisa Yoneyama announced in 1952. Pros and cons emerged, and the so-called “Meridian controversy” raged for about two years. Documents relating to this controversy along with basic research on the meridian and the meridian point during the period were collected, arranged, examined, and presented at Workshop i of the 51st Annual Meeting of the Japan Society of Acupuncture and Moxibustion which was held in Tsukuba in June 2002. This is a condensed version of the reports.
RESUMO
Human skin sections of the Goukoku (LI·4)-corresponding area and its surroudings were collected and they were stained with H. E. dyes. Abundant nerve fibers and blood vessels were observed in the Goukoku (LI·4)-corresponding area, while their numbers were slightly decreased in the non-acupoint area on the meridian. Their numbers in the extra-meridian non-acupoint area were the lowest.<br>Substance P-containing nerve fibers were examined by histochemistry in the same areas, and many of them were observed in the Goukoku (LI·4)-corresponding area. And further more, they were closely associated with lymphatic vessels. These findings suggest the mechanism that Substance-P secreted by the stimulation of acupoint, is transported to the lymph node via lymphatic vessels, thus leading the stimulation of the lymphatic system.<br>Lymphatic vessels with abundant smooth muscles were predominantly noted in the Goukoku (LI·4)-corresponding area and scarcely in the non-acupoint area by fluorescent stain. This finding suggests that hypersensitive one may feel the contraction of lymphatic smooth muscle induced by the Substance-P as a phenomenon of propagated sensations along the meridians (PSM).
