近年,欧米では筋力の低下から来る日常生活への不適応を防ぐために,重量物等を使用した筋力強化運動が盛んに行われるようになってきた。中でも,ダンベル等の重量物を用いて行うアイソトニック・トレーニングは,トレーニングの目標を重さや回数を用いて具体的に決めやすく,手軽に実施できる利点がある。このような観点から,最近ダンベルを使った運動が手軽に出来る運動として,中高年を中心に盛んに行われ始めている。しかし,ダンベル運動実践者の中から重量,回数,頻度等の過負荷からくる関節及び筋肉等の運動器の障害が多く見られるようになった。この問題を解決するために,伸縮性の高いゴムバンドを使った運動が行われるようになってきた。そこで,本研究においてはダンベルを使った運動とゴムバンドを使った運動が生体にどのような影響を及ぼすかについて,力学的に解析することで両運動の特性を明らかにすることした。その結果,力学モデルによる比較においてダンベル運動には激力と呼ばれる筋及び関節を傷害する大きな力が作用することが明らかとなった。また,力学モデルに条件を指定して検討した結果からも同様の結果を得た。従って,筋及び関節への過負荷を防ぎ,運動効果を期待するためにはダンベル等の重量物を使用した運動よりゴムを使用した運動が初心者や中高年には有効であると思われる。

In the summer of 1960 a girl with cerebral paragonimiasis was admitted to the psychiatric service of Chikushi National Hospital from Kami-agata Country (Tsushima Island), Nagasaki Prefecture and she died shortly after hospitalization. Her parents also were suffering from paragonimiasis, and had no knowledge about the disease, Since this incident, we have carried out epidemiologic studies for four years, and some campaign of education regarding paragonimiasis in Tsushima, Namely, parasitologic studies on the crabs, or the skin test, and explanations concerning life cycle of paragonimus using many slides for the inhabitants at various places have been done. In addition to these, since 1961 in every year 2, 000 copies of the pamphlet for education have been distributed to the people in Tsushima. On the other hand through the newspapers, radio and television the importance of prophylactic measure has been emphasized to the inhabitants, According to our studies, parasitic rates of metacelcaria in the Nita River (especially 24.3% in Kurusu), 42.5% in the Mine River, 59.8% in the Kusu River, 58.1% in the Are River, and 80.0% in the Azamo River, which appeared to be high positive rates.High positive results of the skin test obtained from school boys and girls using the VBS antigen were 22.7% in Sago area, 37.6% in Hamagusu, 21.9% in Are, and 23.8% in Naiin. High positive skin test corresponds with high parasitic rate of metacelcaria in the crabs in these districts, In the skin test for 1816 individuals among the inhabitants in Sago, Nita, Mine and Are areas, where appeared to show high infectious rate, the positive rate was 22.6%. In 1962, the questionnaire was sent to every home in order to know the inhabitants' response to our campaign of education and some following interesting data were obtained.The spread rate of knowledge about the disease among the inhabitants are showing remarkable increase, namely 33%, 34% in 1960, 1961, and 1962, respectively.As to the processes obtained the knowledge, 35 per cent of the people owed to the activities of our group, 34% from the talk of folks with this matter, and 2096 from information by the newspapers, radio and television.In Tsushima, the most families (93 per cent) have tasted the crabs and in 1960 48.2% of the inhabitants ate the crabs. Year by year, however, the eating ratio of crabs was decreasing, i. e., it was 21.9% in 1961, and in 1962 it dropped to only 2.9%. As to the cooking ways of crabs, 66% of people took Miso soup containing grinded crabs, but no one showed such habit as eating the raw crabs.Since 1960 111 carriers of paragonimus eggs have been found, among them 74 instances by us, 35 cases by the Institute of Endemic Diseases, Nagasaki University, and 9 by doctors in Tsushima. In 1963, under cooperation with the National Tsushima Hospital, group treatment for paragonimiasis cases with Bitin was made and 50 volunteer cases have completed the treatment.

The purpose of this investigation is to evaluate the effects of muscle pump by pedaling exercise on blood circulation and define its properties. Lower body pressurization device equipped with bicycle ergometer was used to provide negative pressure on the lower body of subjects in recumbent position. Seven healthy male collage students volunteered for subjects.Whole experiment for each subjects was divided into control stage (0 mmHg), -20, -40, and -60 mmHg LBNP (lower body negative pressure) stage. Preceeded by resting period, 25, 75, and 125 W exercise in experiment 1, 50 and 100 W exercise in experiment 2 were loaded using bicycle ergometer with revolution of 60 rpm during each stage. Following parameters were determined: HR, SV, Q, and blood pressure.The results obtained were as follows;(1) In resting condition, LBNP caused significant decrease in SV and Q in spite of marked compensatory increase in HR.(2) These effects of LBNP were cancelled in -20 mmHg or mostly cancelled in -40 and -60 mmHg by pedaling exercise of 50 W or more.(3) Effect of muscle pump by pedaling exercise is apparent in light exercise such as 25 or 50 W arriving to a plateau with more intensive load.(4) Muscle pump action by the same exercise condition is more effective under more severe LBNP.(5) Light exercise in LBNP caused decrease in HR, probably because of pressure reflex initiated by restoration of blood pressure.These results leed us to a conclusion that light pedaling exercise produces a powerful pumping action nearly enough to compensate the circulatory disturbance by strong LBNP.

To investigate the genetic variation of Jomon dogs (Canis familiaris) in Japan, partial sequences of the mitochondrial DNA (mtDNA) control region were determined from dog bone remains, which were excavated from two Jomon-period archaeological sites, the Kamikuroiwa Rock Shelter site in Ehime Prefecture (Shikoku Island) and the Higashimyo site in Saga Prefecture (Kyushu Island), Japan. Of seven individuals from the Kamikuroiwa Rock Shelter site, the mtDNA sequences from two individuals were successfully determined. Comparison of the resultant 215 base pair sequences with previously reported sequences showed that one of these two individuals had a new haplotype, named KRA1, and that the other had the previously reported M1 haplotype. For the Higashimyo site, three of 11 individuals yielded successful sequences. Two of these three individuals shared M1 and the other one had M20, both of which are haplotypes previously reported in modern Japanese dogs, but had not been found in any Jomon dogs. The success rate in the present study was 27.8% (5/18 samples). It is noticed that the three mtDNA haplotypes (M1, M20 and KRA1) were found in Jomon dogs for the first time. In addition, sequence data were obtained from Jomon dogs in Shikoku for the first time. The results suggest that the genetic lineages in the Jomon dog populations were more polymorphic than previously reported, and that at least some maternal lineages shared in the Jomon period descended to modern dogs on the Japanese islands.

[Purpose] To determine the potential factors for difference in metabolic profiles between metabolically healthy obesity and metabolically unhealthy obesity, we investigated the difference in abdominal fat volume, metabolic characteristics, and physical activity levels between metabolically healthy obesity and metabolically unhealthy obesity identified with cardiovascular disease risk factors in Japanese males. [Participants and Methods] Of 305 volunteers recruited, 130 obese males (age: 46.9 ± 8.9 years; body mass index: 29.6 ± 3.5 kg/m2) met the criteria for the study. They were divided into two groups; metabolically healthy obesity and metabolically unhealthy obesity according to cardiovascular disease risk factors including low-density lipoprotein cholesterol. Abdominal fat volumes were measured using magnetic resonance imaging. Cardiovascular disease risk factors and metabolic characteristics were evaluated by blood pressure and blood parameters. Physical activity levels were measured using an accelerometer. [Results] Despite the fact that metabolically healthy obesity had a more favorable metabolic profile than the metabolically unhealthy obesity, no significant differences in visceral and subcutaneous fat volumes were found between the two groups. Moreover, the metabolically healthy obesity had a significantly greater physical activity expenditure and moderate-to-vigorous physical activity level than the metabolically unhealthy obesity. [Conclusion] A more favorable metabolic profile in metabolically healthy obesity may be associated with physical activity level rather than abdominal fat volumes in Japanese males.

Objective: We measured the formant frequency of vowels in retrusion patients and normal healthy control patients, and made a comparative study of the purpose in phonology. We wanted to know how orthognathic surgery has influenced the articulation of vowels in patients. We investigated how the relationships between the position of the maxilla and mandible and incisor occlusion affected vowel sounds. And because resonance space is believed to affect sound frequencies, we investigated the effect of the width of the airway preoperatively and postoperatively on vowel sounds.Methods: Five vowel sounds in 10 Japanese patients with mandibular retrusion requiring surgery for jaw deformity and malocclusion preoperatively and at 3 and 6 months postoperatively were recorded and compared with those in normal healthy control patients. Also, the effect of the positional relationship between the maxilla and the mandible and incisor occlusion on these vowel sounds was investigated by correlating skeletal and denture patterns of cephalometric measurements taken preoperatively and at 3 months postoperatively with these vowel sounds. The width of the airway was measured preoperatively and 3 months after the operation, and the correlation with the frequency of the vowels was examined.Results: In /e/ F1, /o/ F2-F1, significant differences were observed between the preoperative patients and the control patients. However, these differences disappeared at 3 and 6 months postoperatively.A significant difference was admitted with F1 of /a/ and F1 of /e/ in comparing the preoperative with the postoperative patients 6 months by a rank test with a sign of Wilcoxon.Both preoperatively and postoperatively, positive correlations were observed between F2-F1 the narrow, open vowels /i/ with SNA and SNB. In the preoperative patients, some correlations were observed between F1 the semi-narrow, open vowel /e/ and denture patterns.Significant increases were observed between the preoperative and 3 months postoperative patients in the width of the hypopharyngeal cavity. Many correlations were observed between the change of width of the airway and the vowel frequency, particularly in the posterior tongue vowel /u/. But other vowels had few correlations.Conclusion: A change of occlusion of the front teeth and a change of frame by the mandible correction operation greatly influenced close vowels and half close vowels that were a front tongue vowel, especially the influence of /i/ and /e/ in retrusion patients. It was an interior tongue vowel that the change in the airway influenced the vowel frequency of only /u/.

【要旨】2011年,大阪市あいりん地区にあるホームレスを支援する施設,シェルター,診療所,および,サンフランシスコ市の社会施設,病院,教会を視察した。その後,8年が経過し,結核やエイズに関する公衆衛生施策,栄養指導等の公衆衛生活動が行われた結果,両市で結核の患者数は減少していた。我が国では専門職が中心になってDOTSを行っているが,アメリカでは医療資格がない者が訓練を受けてDOTSを行っており,DOTSに関する国の経済的負担は少ない。しかし,サンフランシスコ市のような大都市では手頃な価格の住宅の欠如,精神疾患,暴力,エイズ,薬物等の問題がある。また,アメリカの企業は終身雇用ではないため,突然解雇されてホームレスになることがある。経済的な格差は健康格差を生むため,健康,労働,教育,福祉などさまざまな側面から公衆衛生活動について考える必要がある。蔑視せず,現実をしっかりと見て,彼らに寄り添い,今後どのようにしたらいいのかを共に考えなければならない。このような状況の中でアウトリーチ・ワーカーやボランティア等,専門家ではない一人の人として関わりや信頼関係の構築が,ホームレスにとって他のどのような支援よりも遙かに大きな力になっている。差別することなく共に考えることが一番の支援である。

Fuel injection pressure decreases in four-stroke diesel engines after extended operations. Poor combustion caused by the pressure drop is a serious problem that can lead to environmental pollution. Several factors have been considered to be behind mechanisms to decrease fuel injection pressure, but the details of such mechanisms are still unknown. Up until now, only limited numbers of studies have been conducted to define these mechanisms. In this study, we clarified that stress relaxation, buckling and metal fatigue of the pressure regulating spring in the fuel injection valve contribute to lowering injection pressure. We also found that the lowering of injection pressure causes early and prolonged injection in diesel engines.
