BACKGROUND: Neuropathic pain is a global clinical problem; nevertheless, nerve injury treatment methods remain limited. Olanzapine has antinociceptive and anti-nueropathic properties; however, its preventive effects have not been assessed in nerve injury models. METHODS: We prepared a partial sciatic nerve ligation (Seltzer model) or sham-operated model in male Sprague-Dawley rats under isoflurane anesthesia. In a pre-treatment study, we administered olanzapine (10 mg/kg) intraperitoneally 1 h before nerve ligation. In post-treatment and dose-dependent studies, we injected 3 different doses of olanzapine intraperitoneally 1 h after nerve ligation. Mechanical allodynia was measured before and 7 days after surgery. Immunohistochemical analysis using anti-Iba-1 antibody was used to assess the effect of olanzapine at the spinal level. RESULTS: In the pre-treatment study, median withdrawal thresholds of the normal saline groups were significantly lower than those of the sham-operated groups; however, those of the olanzapine (10 mg/kg) and sham-operated groups were not different. In the post-treatment and dose-dependent studies, the median withdrawal thresholds of the olanzapine (2.5 mg/kg) and normal saline groups were not different; however, those of the olanzapine (10 and 50 mg/kg) groups were significantly higher than those of the normal saline groups. Olanzapine did not have a significant effect on the density of Iba-1 staining. CONCLUSIONS: Olanzapine attenuated mechanical allodynia dose-dependently in the Seltzer model. This anti-allodynic effect of olanzapine was observed even when injected 1 h after nerve ligation. This effect of olanzapine appeared to be unrelated to microglia activation in the ipsilateral dorsal horn of the lumbar spinal cord.

The Korean Acupuncture and Moxibustion Medicine Society (KAMMS) celebrated its 50th anniversary with a commemoration ceremony and a Japan-Korea Symposium held in Seoul in November 2023. This report outlines the participation and highlights from the commemoration ceremony celebrating the 50th anniversary of KAMMS on November 11 (Saturday), along with insights shared during the Japan-Korea Symposium held as a special session within KAMMS' Fall Academic Conference 2023 on November 12 (Sunday). The summary includes presentations delivered by four speakers during the symposium. The Korean session focused on "Collaborative-Based Integrated Healthcare," discussing endeavors in integrated medicine involving Western medicine and Korean medicine. Meanwhile, the Japanese session titled "Introduction of Acupuncture Clinics in Japanese University Hospital" highlighted efforts in acupuncture and moxibustion education within the Tohoku University Hospital in Japan.

[Objective] To clarify the utilization of characteristics and reactions of acupuncture points, and the frequency of using acupuncture points in acupuncture and moxibustion treatment in Japan.[Methods] We conducted a questionnaire survey involving members of the Japan Society for Oriental Medicine and those of the Japan Society of Acupuncture Course in Universities. The contents of the questions included age, sex, profession, length of clinical experience of acupuncture/moxibustion, treatment method, utilization of characteristics and reactions of acupuncture points, and frequency of using acupuncture points in both acupuncture and moxibustion treatment.[Results] The number of valid questionnaires was 59 (59 for acupuncture treatment and 50 for moxibustion treatment). The respondents were as follows : average age of 52 ± 12 years, 45 males and 14 females, 13 medical doctors and 46 acupuncturists, clinical experience of 21.1 ± 11.5 years. Most practitioners utilized ill ness-specific features of acupuncture points, de qi, and reactions they feel with their needling and pressing hands. Ten acupuncture points were used in 50% of patients in acupuncture treatment, and ST 36 and SP 6 were the most frequently used. On the other hand, no single acupuncture point was used in more than 50% of patients in moxibustion treatment. Thirteen acupuncture points were used in 30% of patients in moxibustion treatment, and BL 23, SP 6, and ST 36 were the most frequently used.[Conclusion] Our survey clarified the usage of acupuncture points in acupuncture and moxibustion treatment in Japan.

The background and course of Kampo treatment in 39 patients with uncontrollable otolaryngeal symptoms treated between April 2013 and March 2016, in the Department of Kampo Medicine at Tohoku University Hospital, were analyzed retrospectively. An improvement in overall symptoms was noted with Kampo treatment in 28 of 39 cases (71%). The commonly reported subjective symptoms included glossodynia (7 cases), postnasal drip (4 cases), oral discomfort (4 cases), dizziness (3 cases), and taste disorder (3 cases). Analysis using the classification of qi, blood, and fluid revealed that cases with qi stagnation pattern (15 of 18 cases) were effectively treated with Kampo treatment. Prior reports support our finding that smoothing qi with Kampo medicine is effective in alleviating some chronic symptoms. The symptoms improved within 6 weeks after the treatment was initiated. Therefore, a 6-week period can be considered sufficient to determine the effectiveness of Kampo medicine. Many of the patients for whom Kampo treatment was not effective had depression and domestic stress. In conclusion, Kampo treatment may be effectively used to treat uncontrollable, chronic otolaryngeal symptoms in selected cases that are unresponsive to Western medicine.
