Acupuncture anesthesia has been practiced in China since about 1960. In Japan, Hyodo reported 30 cases of acupuncture anesthesia in 1972. However, from around 1980, the direction of acupuncture investigations turned from anesthesia to analgesia. Acupuncture analgesia is presently considered a way to activate the body's endogenous analgesic system. Recently, with the rise of acupuncture as one of the most well known CAM therapies, acupuncture or moxibustion treatment has been reported for both acute and chronic pain. Even so, few clinical reports and original articles have been reported in Japan. This review illustrates how acupuncture is being used in Japan for acute pain such as surgical operations, post- operative pain (POP), neuropathic pain, pain associated with teeth extractions and after the extraction of impacted wisdom teeth.

Objective Although electroacupuncture (EA) therapy is used to relieve various kinds of pain, the optimal frequency and duration of EA remain unclear. We investigated the effect of varying frequency and duration of EA during hyperalgesia elicited by carrageenan-induced inflammation. Methods Carrageenan was administered by subcutaneous intraplantar injection to induce inflammation. Nociceptive thresholds were measured using the paw pressure threshold (PPT) (Randall-Selitto Test). EA was applied at 3, 15, or 100Hz to the left anterior tibial muscles for 1, 15, or 60 minutes. Intensities used were chosen within the known tolerance of the animal, and increased up to 3mA for 3Hz, and up to 1.5mAfor 15 and 100Hz. EA was started three hours after carrageenan injection. Results Three hours after carrageenan injection, a marked ipsilateral inflammatory response appeared and PPT decreased significantly. This decrease persisted for at least 24 hours after carrageenan injection. EA at 3Hz (60 minutes) resulted in significant increases of PPT which persisted for 24 hours after injection. EA at 3Hz (15 minutes) also induced PPT elevations immediately and for one hour after EA compared to the control group. However, no other variety of EA significantly increased PPT. Conclusion These results show that EA produces electroacupuncture analgesia of carrageenan-induced hyperalgesia. These findings also suggest that, among the frequencies and durations tested, EA at 3Hz (60 minutes) is the most suitable frequency and duration for carrageenan-induced inflammation. It seems that EA has different analgesic effects and mechanisms according to the parameters of stimulation. For EA in the clinical induction of analgesia, it is especially important that an effective frequency and duration are selected.

Premenstrual dysphoric disorder (PMDD), a severe type of premenstrual syndrome (PMS), is characterized mainly by psychological symptoms confined to the premenstrual period, which reduce not only patients' quality of life, but also their working activities. Although various therapies have been employed for PMDD, some patients do not respond to them. We recently employed acupuncture treatment for a patient in PMDD. Symptoms ameliorated during the acupuncture (+) period, but deteriorated during the acupuncture (-) period. This review describes the clinical course of this case. The diagnosis and treatment of PMDD are briefly summarized and previous acupuncture treatment for PMS are reviewed. The difficulties in evaluating the effectiveness of acupuncture for PMS/PMDD are addressed. It is suggested that acupuncture may be a treatment option for PMDD.

Objectives: Needle and laser acupuncture are often used to improve the success rate of assisted reproductive technology (ART). This study examined whether needle or laser acupuncture ameliorated the emotional distress experienced by infertile women undergoing in vitro fertilization and embryo transfer (IVF-ET) or intracytoplasmic sperm injection (ICSI). Materials and Methods: Fifty-one infertile women who were undergoing IVF-ET or ICSI received needle acupuncture (needle-acupuncture group; n = 32) or laser acupuncture treatment (laser-acupuncture group; n = 19). The emotional distress experienced by the infertile women was evaluated using 2 questionnaires-the Profile of Mood States (POMS) and the State-Trait Anxiety Inventory (STAI)-both before and after 3 months of treatment. Results: In the needle-acupuncture group, the POMS detected significant post-treatment reductions in tension/ anxiety (P < 0.001), depression/dejection (P < 0.001), anger/hostility (P < 0.001), confusion (P < 0.05), and total mood disturbance (TMD; p < 0.001). However, the POMS scores for vigor/activity and fatigue were not altered significantly after the treatment. In the STAI, both State and Trait scores had significantly decreased after the acupuncture (P < 0.001 and P < 0.05, respectively). In the laser-acupuncture group, the POMS detected significantly lower tension/anxiety (P < 0.05) and vigor/activity (P < 0.05) scores after the treatment. However, the POMS did not detect significant changes in depression/dejection, anger/hostility, fatigue, confusion, or TMD after the treatment. Furthermore, neither the STAI-State nor the STAI-Trait score had significantly decreased after the laser acupuncture treatment. Conclusions: These results indicate that needle and laser acupuncture ameliorate the emotional distress experienced by women who are undergoing IVF-ET or ICSI.
