Objective: To develop an effective and safe therapeutic strategy, we studied the effect of the clinical characteristics of patients with acute drug intoxication on the duration of hospitalization.
Subjects and Methods: The subjects were 89 patients hospitalized for acute drug intoxication. They were divided into two subgroups; the short hospitalization group (duration of hospitalization < 7 days) and the long hospitalization group (duration of hospitalization ≥ 7 days). We compared age, sex, vital signs, drugs, and therapy between the two groups.
Results: There were no significant differences in sex or severity of consciousness disturbance between the short- and long-hospitalization groups. Age in the latter group was higher than that in the former, and age was significantly and positively correlated with the duration of hospitalization. Prolongation of hospitalization in patients with Japan Coma Scale (JCS) I or II is associated with psychiatric disease, and in patients with JCSIII, with physical disease. We used direct hemoperfusion (DHP) to treat patients with severe acute drug intoxication. The duration of hospitalization in patients treated by DHP tended to be shorter than those not so treated.
Conclusions: The present results suggest that aging is associated with prolongation of hospitalization and the onset of physical disease among patients with acute drug intoxication. When elderly patients with acute drug intoxication are treated in a primary-care setting, the question of whether or not physical diseases are present as complications should be considered. The appropriate use of DHP for the treatment of patients with severe acute drug intoxication requires further study.

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.

The first topic:Study of PSC in Japan and China.
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.

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.

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.

The second topic:Specific locations of meridian points and clinical effects of the meridian point.
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.

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.

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.
1st theme : Anatomical examination of the meridian and meridian point.
1) Anatomic structure showing path and meridian running. (Kenji Matsuoka) : Similarity of meridian pathway and course of nerve and blood vessels in cadaver.
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.
2nd theme : Study of acupuncture safety depth in Japan and China.
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.
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.
3rd theme : Examination of clinical effect of a few meridian points.
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.
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.

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.

During the 23 years since this pain clinic was founded, 29, 458 patients have been treated here (about 385, 000 patient visits in total). In the earlier days, patients with whiplash injury (posttraumatic neck syndrome) were predominant. More males than females visited our clinic in those earlier days. Several years after this clinic opened, the percentage of female patients became higher (55% or more) than the percentage of male patients. Reflecting the social trend of an increase in the percentage of elderly people in the total population, the percentage of patients between 60 and 80 years of age has been increasing. Patients who visit this clinic live primarily in Osaka Prefecture. However, it is not uncommon that patients living in other prefectures of the Kinki district visit this clinic. Although patients visit our clinic because of various complaints, they often suffer from chronic, intractable complaints, such as low back pain, combined pain of the lower back and legs, and postherapuetic neuralgia. They often visit our clinic as a last resort for healing, after having consulted many other institutions. The duration of sickness among patients who visit our clinic is long (often over 5 years). Although the methods of treatment and the patients' responses vary, depending on their diseases, the combination of nerve block with acupuncture seems to be more effective on pain. We have utilized various techniques of acupuncture, including the in situ needle acupuncture, low-frequency therapy, SSP therapy, laser therapy and hyperthermia.

In the present paper, we examined differences in therapeutic effectivenesses of venous methods of acupuncture, ranging from filiform needle to EAP, LFEA, laser and SSP, in cases with shoulder stiffness. The immediate and delayed effect of each method, comfortableness during treatment session, changes in temperature, blood flow, and the oxygen density at the Jianjing and Hegu point were examined.
Significant improvement was seen in every therapeutic method. Electrical acupuncture using direct current was most effective. No difference were evident among SSP, low-frequencey electro-acupuncture and filiform needle. There was a correlation between confortableness and the improvement rate in electrical acupuncture using direct current and laser acupuncture. Deep temperature, blood flow and the degree of oxygen saturation of the stimulated part tended to increasd in each case.
