Acupuncture and Judo-Therapy Students' Attitude to Medical Aromatherapy-A Questionnaire Survey / 日本補完代替医療学会誌

<i>Objective</i>: In order to assess usefulness, applicability and problems of aromatherapy in the modern medical practice.<br> <i>Method</i>: We conducted a questionnaire survey on the recognition and utilization of complementary and alternative medicine (CAM) and medical aromatherapy in a professional school of acupuncture and Judo-therapy in Osaka City. The respondents were 866 students at the school.<br> <i>Results</i>: We found that 97.1% of the respondents had experienced at least one CAM therapy and 25.8% had aromatherapy. Compared to male students, more female students used aromatherapy. Perceived effectiveness of aromatherapy for purpose of the use ranged between 73.8% and 89.2%. Approximately 70.0% of the respondents were interested in medical aromatherapy, and 89.4% expected this therapy for psychosomatic/mental diseases. Main problems pointed out were collecting more scientific evidence and reducing the costs.<br> <i>Conclusion</i>: The results suggest that aromatherapy may become more widespread and one of the options to make the current clinical practice more satisfactory for patients.<br>

The Outcome of Our Smoking Cessation Interventions Project in the Past 6 Years: A Study of 1-Year Abstinence Rates / 日本農村医学会雑誌

Background/Objectives: Since April 2006, smoking cessation treatment has been included in public health insurance coverage, although conditionally. The tobacco control program usually takes 12 weeks or so. When it comes to the form of treatment, most medical care facilities adopt nicotine replacement therapy (NRT) at their outpatient ward. The cessation success rates are considered not so high as before. In stead of treating nicotine-addict outpatients individually, our hospital has been offering a stop-smoking program all its own since 1999. This study was designed to examine the results of our efforts in the last six years retrospectively.Subjects/Methods: Enrolled for this study were 232 patients who had participated in our six-month smoking cessation program between 1999 and 2005. A non-smokingsupport team made up of a physician, pharmacist(s), nurses, dietitian(s) and physical therapist(s) takes care of groups of participating patients, each group consisting of 10 or less. The patients undergo behavior therapy throughout the 6-month period and NRT in the first eight weeks. Under the program, nutrition guidance is offered regularly by dietitians for weight control and physical exercises by physical therapists for relief from the stress due to abstinence from smoking. We took a questionnaire survey of all the subjects and worked out the ratios of those persons who had remained abstinent up to one year after they stopped smoking to the total.Results: The rates of abstinence maintained eight weeks, six months and one year after the start of cessation were 78.4%, 70.3% and 64.7%, respectively. Of those who were still abstinent, 78.0% replied that they found it easy to resist the urge to smoke cigarette thanks to the smoking cessation program.Conclusion: Our six-month participatory tobacco control program was found effective as high cessation rates were maintained.

The situation of the assistance for the physically disabled people in Cambodia / 国際保健医療

Many people have been killed or physically disabled during twenty-year internal conflict in Cambodia. People still get injured due to remained land mines and unexplosive ordnances, even a decade after the cease-fire. This paper aims to examine the situation of the physically disabled and assistance programs in Cambodia by analyzing published documents and visiting activity sites, and to discuss future challenges. In this paper, the physically disabled mainly implies adults and children with orthopedic impairments.<br>The major causes of physical disability are: land mines; unexplosive ordnances; traffic accidents; occupational accidents such as falling down from palm trees; infectious diseases, etc. Casualties of land mines and unexplosive ordnances were 50,915 (13,686 were dead) between 1979 and 2000. Recently, the number of land mine accidents has been declining, while that of traffic accidents has been increasing. <br>Since 1980s, many international NGOs have assisted land mine victims through providing with artificial limbs, prostheses and rehabilitation services. However, the assistance for the disabled people of other categories has been neglected. The international NGOs provide services based on their own interests, therefore, the participation of the disabled people and their family in the assistance programs has been limited. The government plays only limited roles to endorse the activities of the international NGOs, and has not had any specific strategies to prepare for the future withdrawal of the NGOs.<br>Disabled people require assistance not only for health, but also for education, employment, etc. On the other hand, it is also very important to empower and build capacity of them, so that they can contribute to the development of the Cambodian society. Additionally, means of prevention should be considered as one of the key perspectives. Sustainable supporting systems should be established by the government and domestic NGOs through participation of the disabled themselves.

Lack of integrative control of body temperature after capsaicin administration

BACKGROUND: Body temperature is usually regulated by opposing controls of heat production and heat loss. However, systemic administration of capsaicin, the pungent ingredient of hot peppers, facilitated heat production and heat loss simultaneously in rats. We recently found that the capsaicin-induced heat loss and heat production occur simultaneously and that the biphasic change in body temperature is a sum of transient heat loss and long-lasting heat production. Moreover, suppression of the heat loss response did not affect capsaicin-induced heat production and suppression of heat production did not affect capsaicin-induced heat loss. These observations suggest the independent peripheral mechanisms of capsaicin-induced thermal responses. Thus, the capsaicin-induced thermal responses apparently lack an integrated control. METHODS: Male Wistar rats were maintained at an ambient temperature of 24 1 degrees C on a 12 h on-off lighting schedule at least for two weeks before the experiments. They were anesthetized with urethane (1.5 g/kg, i.p.) and placed on a heating pad, which was kept between 29 and 30 degrees C. Skin temperature(Ts) was measured with a small thermistor, which was taped to the dorsal surface of the rat's tail, to assess vasoactive changes indirectly. Colonic temperature(Tc) was measured with another thermistor inserted about 60 mm into the anus. O2 consumption was measured by the open-circuit method, and values were corrected for metabolic body size (kg0.75). Capsaicin (Sigma) was dissolved in a solution comprising 80+ACU- saline, 10+ACU- Tween 80, and 10+ACU- ethanol, and injected subcutaneously at a dose of 5 mg/kg. Each rat received a single injection of capsaicin because repeated administration of capsaicin renders an animal insensitive to the subsequent administration of capsaicin. Laminectomy was performed at the level of the first and second cervical vertebrae to expose the cervical spinal cord for sectioning. The brain was transected at 4-mm rostral from the interaural line with an L-shaped knife. RESULTS: After administration of capsaicin, O2 consumption increased from 13.5 0.4 mL/min/kg0.75 at 0 min to a peak of 15.9 0.4 mL/min/kg0.75 at 71 min and gradually declined but remained higher than the basal value until the end of the 4-h observation period. Ts also immediately increased from 27.7 0.2 degrees C to 31.9 0.3 degrees C at 39 min, and it returned to the baseline level within 90 min after the capsaicin administration. Tc initially decreased from 37.1 0.1 degrees C to 36.8 0.2 degrees C at 43 min and then gradually increased over the baseline level and remained at 37.6 0.2 degrees C until the end of the experiment. In spinalized rats, the capsaicin-induced increases in O2 consumption was largely attenuated, while the basal O2 consumption was similar to that of control rats. The basal Ts of spinalized rats was 32.4 0.3 degrees C, which was higher than that of control rats. Capsaicin increased Ts by less than 1 degree C, and Tc did not change after the capsaicin administration. O2 consumption of decerebrated rats was statistically higher than that of control rats after the injection of capsaicin. However, capsaicin did not increase Ts, showing a lack of a vasodilatory response. Decerebration between the hypothalamus and midbrain prevented the capsaicin-induced heat loss but not the heat production response. CONCLUSION: These results show that the capsaicin-induced heat production and heat loss are controlled separately by the brainstem and by the forebrain, respectively, and suggest that the body temperature regulation is performed without an integrative center.

The effects of Acupuncture Treatment on the improvement of Visual Acuity / 全日本鍼灸学会雑誌

The aim of this study was to investigate effects of acupuncture treatment on the improvement of visual acuity.<br>Six patients (male: 5, femal: 1, aged: 20-24) in the department of Ophtalmology were diagnosed with myopia grevis.<br>Used acupoints were EX-HN4, Jingming (B1), Hegu (Li4), Feugchi (G20), which were stimulated with the leaving needl techniqe for 10 minutes.<br>Acupuncture treatment was performed everyweek.<br>After 10 times treatment, the effect of acupuncture on visual acuity was evaluated.<br>As a result, three patients showed a remarkable improvement of the visual acuity and others not subsequently, the improved patients observed for 5 to 7 weeks without treatment in order to examine the durability of acupuncture effects.<br>While, the other three patients were treated with the electro-acupuncture instead of the leaving needl technique.<br>The visual acuity of the patients in whom acupuncture effective declined without treatment, but their visual acuity was kept at on higher level than before treatment.<br>On the other hand, the visual auity of the other patients improved by using electro-acupuncture.<br>These results suggest that acupuncture treatment is effective in improbvement of visual acuity and the effect remains for a certain period, and electro-acupuncture is effective when we do not get effect on vusual acuity with the leaving needle techniqe.
