Generally, sport players of boxing or football who contact roughly with other players use mouth guard during match or game to prevent the breaking of jow boneor bursting of soft oral cavity. Moreover, mouth-guard are used for the purpose to lighter the load to root of teeth and to improve the skill and power of sport's player.
The purpose of this study was to examine the charactaristic of unfitted by H shape-mouth guard compared to U shape mouth guard.
The following results were obtained.
1. The H shape-mouth guard of this study could reduce the impact to 1/7 level.
2. A relative decrease in ventilation level was shown when H shape mouth guard fitted.
3. With reference to respiratory function, reduction of the amount of oxygen up-take was not observed at heart rate lower than 170 beats/min, and in this case a player feells subjective symptom of stiffing.

We have developed a mouth guard which has revolutionized the shape and material of the conventional mouth piece. The H shape mouth guard has the unique shape like that of an H. Even with the new shape of the mouth piece it does not hinder the performance of the wearer. The following are the fundamental data collected by our group. In this study we examined its influences on leg power, the carry (the distance a golf ball is hit) and the motion of the club head during a tee off.
The results are as follows:
1) By wearing or setting the mouth guard, the variation of leg power, measured with a Sybex II, showed an increase at selected angular verocity. The rate of increase averaged aproximately 15%.
2) The amount of work in anaerodush, an intensive, but short exercise, increased significantly by 1.25 seconds.
3) As for golf, all four of the test subjects joint performance increased their carries by 5.2 to 11.6 yards, using a 1st wood.
4) Also the fluctuation of the head of the club decreased from 7.3 cm to 3.6 cm on average.
Our group have found that the new H shaped mouth guard can absorb shock as well as not hinder the performance of the individual who is wearing it. Thus, the H shape mouth guard can be worn during sports to enhance the participant's performance.

We evaluated the efficacy, usefulness and safety of acupuncture and moxibustion treatment in rheumatoid arthritis, by the randomized, parallel-group, multi-center study with the drug-treated outpatient group as the control. The endpoints, important in the clinical assessment of acupuncture treatment, included the improvement criteria in ACR core set variables and the Japanese version of the Arthritis Impact Measurement Scales Version 2 (AIMS-2), a system of evaluation of the QOL of patients with RA.
Regarding intervention (therapy), a therapy chart for each stage of disease was drawn up to give local and systemic treatment in consideration of the patient's activity and disability in each stage of rheumatoid arthritis, so that generally consistent therapy adapted to the patient's condition would be provided. Result 1. Patients eligible for analysis were 80 patients of A-group (drug therapy group) (80 females, 2 males, 2dropped) and 90 patients of B-group (drug plus acupuncture and moxibustion group), total 170 patients. 2. Patients who satisfied the improvement criteria in ACR core set variables (improved patients) were 8 of 80 patients in A-group and 20 of 90 patients in B-group. The improvement rate was significantly higher for B-group treated by drug plus acupuncture and moxibustion versus A-group, with P=0.04 in 2×2 table chi square test. 3. In QOL change investigated by AIMS-2 questionnaire, the improvement occurred significantly more frequently in the drug plus acupuncture and moxibustion group, with difference between groups at 12 months after the initiation of clinical study at P=0.001. 4. Changes in the subjects included in AIMS-2 questionnaire: Improvement was significantly more frequent in the drug plus acupuncture and moxibustion group versus drug therapy group in respect to the ability to walk, finger function, housework, sociableness, pain, mood, and the degree of subjective improvement. In the present randomized, parallel-group, multicenter study, a significant improvement was detected in the drug plus acupuncture and moxibustion group versus the drug therapy group in the aforesaid respect, which suggested that the use of acupuncture and moxibustion combined with the conventional therapy would prevent deterioration of physical functions, improve blood circulation, stabilize mental status, and thereby contribute to the improvement of QOL in patients with rheumatoid arthritis.

BACKGROUND/OBJECTIVES: This study aimed to examine the association of Japanese schoolchildren's involvement in at-home meal preparation with food intake and cooking skill. SUBJECTS/METHODS: We included 1,207 fifth-grade children aged 10-11 years and one parent of each child. A cross-sectional survey was used to collect data on involvement in at-home meal preparation. Correspondence analysis was used to classify involvement in at-home meal preparation into three groups: food-related activities (cooking only or with other activities such as shopping, table-setting, clean up, and dishwashing), non-food-related activities (table-setting and/or clean up), and no (helping) activities. Food intake was assessed using a food frequency questionnaire. Logistic regression models were used to examine involvement in at-home meal preparation associations. RESULTS: The sample consisted of 1,207 fifth-grade children. Vegetable intake was lower in the no (helping) activities group than the food-related activities group (95% CI; boys: 1.2, 5.1, girls: 2.0, 8.9). Fewer children in the non-food-related activities group reported they were able to make a portion of their meals compared with the food-related activities group (95% CI; boys: 1.6, 3.5; girls: 1.5, 3.2). CONCLUSIONS: Children in the food-related activities group showed more favorable food intake and cooking skills than children in the no (helping) activities or non-food-related activities group.

Background: In the end stage of malignant bone and soft tissue tumors with lung metastasis, it is often necessary to relieve symptoms of dyspnea due to tumor enlargement and carcinomatous lymphangitis. We report a case in which nasal continuous positive airway pressure (nasal CPAP) was effective as a palliative treatment. Case: A 66-year-old male underwent wide resection with a diagnosis soft tissue sarcoma of right femur. Four years after surgery, he was hospitalized for hilar lymph node metastasis, multiple bone metastases, and carcinomatous lymphangitis. He was treated with nasal CPAP for dyspnea, and communication was possible until the day before his death. Discussion: For end-stage respiratory symptoms, medication therapy such as morphine or steroids is often used for palliation, but often symptoms are not sufficiently improved. Nasal CPAP might be a useful treatment for palliation for rapidly progressing respiratory failure.
