We investigated various measurement items, for example, local cold tolerance, measurement of physical fitness and questionnaire about a lifestyle in five cities of East Asia. The database was made based on these findings. By using the present database, we can investigate the actual situation of a lifestyle and developmental state of children living in urban area of East Asia. In this report, we describe and discuss the result that compared Japan with other cities in East Asia.

The purpose of this study was to investigate the effects of 12weeks of physical training on cardiovascular responses to postural change at 27℃ and 35℃. 16 sedentary subjects were assigned to either a training group (n=8:30-min ergometer at 60% V^^・O_2peak, 3 days a week) or a control group (n=8 : no exercise). Measurements were made of heart rate (HR), stroke volume (SV), cardiac index (CI), mean blood pressure (MBP), total peripheral resistance (TPR), rectal temperature (Tr), mean skin temperature (Tsk) and heart rate variability (HRV), before and after a chronic physical training. After training, training group significantly increased their V^^・O_2 peak (+10.3%, p<0.01). As for the cardiovascular responses to head-up tilt, in both group there were significant interaction effects between postural condition and ambient temperature in HR, CI and TPR. In training group, HR was significantly decreased after training during head-up tilt at 27℃. These results suggest that the physical training may effect on cardiovascular responses to postural change.

Objective: The purpose of this study is to determine whether the statistics from three published reports on Parkinson's disease (PD) are mutually interrelated and to clarify the relationship between the prevalence statistics and mortality statistics of PD. These statistics included data on “number of patients with PD (PD Patients)”, “number of patients with PD receiving financial aid for treatment (PD Recipients)” as an indicator showing the prevalence of PD, and “number of deaths from PD (PD Deaths, i.e., mortality)”. Methods: The data on PD Patients, PD Recipients and PD Deaths were cited from “Patient Survey” by Ministry of Health, Labour and Welfare, a report by the Research Committee on Epidemiology of Intractable Diseases and “Vital Statistics of Japan” by Ministry of Health, Labour and Welfare, respectively. The expected PD Patients, PD Recipients and PD Deaths were calculated as products of their respective rates for the entire country and prefecture population, adjusting for a difference in population composition. Observed/expected number ratios (O/E ratio) of PD Patients, PD Recipients and PD Patients were calculated by prefecture. The correlation between the O/E ratios was examined. In addition, the relationships of the O/E ratios with the number of hospitals or physicians per person were examined. Results: There were no significant correlations between the O/E ratios of PD Patients, PD Recipients or PD Deaths. The O/E ratio of PD Recipients significantly correlated with the numbers of hospitals and physicians per person. Conclusion: PD Patients and PD Recipients were included in number of people with PD and PD Deaths was derived from people with PD. However, these statistics do not necessarily reflect the prevalence of PD in each prefecture. When using these published statistics as an indicator of the prevalence of PD, it is necessary to clarify the purpose of their use and to comprehend their characteristics.

The purpose of present study was to observe the differences of thermoregulatory responses between atugari (=susceptible to the heat) and samugari (=susceptible to the cold). The subjects were 12 healthy young Japanese adult women (age: 21.8±1.7yrs, stature: 160.5±7.8cm, weight: 49.6±7.5kg, BMI: 19.2±2.4). They put on shorts, T-shirts and short pants. Exposure periods were evening (E) and morning (M) during follicular phase (F) and luteal phase (L). The climatic chamber was controlled at 24℃ RH50%, the temperature increased to 29℃ over 60 minutes gradually. The subjects kept the sitting position. Measurement items were rectal temperature (Tr), skin temperature and subjective sensations. We determined atugari and samugari according to the subjective sensations during exposure. The main results were as follows. 1) The order of values of Tr and mean skin temperature was L・E>F・E>L・M>F・M. 2) The theromoregulatry responses were more influenced by circadian rhythm than menstrual cycle. 3) The order of skin temperature of hand and foot was E<M. 4) Atugari had a tendency to feel warm in the peripheral area and to feel cool in the body stem area than samugari.

The purposes of the present study were to observe the thermoregulatory responses from view points of sex difference, seasonal difference between winter and summer, and susceptibility to the heat (atugari) and the cold (samugari). The subjects were 13 females (20.5±0.5yrs, 159.2±6.4cm, 52.1±6.9kg) and 16 males (20.8±1.6yrs, 172.8±4.5cm, 61.6±6.3kg). They put on shorts or underpants, T-shirts and short pants. In the evening, the climatic chamber was controlled at 24℃ RH50%, the temperature increased to 29℃ over 60 minutes gradually. The subjects kept the sitting position. Measurement items were oral temperature, skin temperature, body weight, heart rate, blood pressure and subjective sensations. We determined atugari and samugari according to the subjective sensations of whole body during exposure. The main results were as follows. (1) The classification of atugari and samugari by self judgment did not always agree with the results of exposure experiments, (2) The skin temperatures were winter > summer in the body stem area and winter < summer in the peripheral area in male and female. (3) The skin temperatures were male < female in the body stem area and male > female in the limbs area. (4) Males felt warm in winter than in summer, and they felt warm than females in winter. (5) The values of subjective sensation were atugari > samugari generally. We guessed that the evening exposure produced these phenomena.

Language：English Publishing type：Research paper (scientific journal)

Objective: The aims of this study were to determine the effects of heavy metals such as manganese on nicotinamideN-methyltransferase (EC 2.1.1.1) (NNMT) activity and to consider the possibility of involvement of NNMT activation in the pathogenesis of heavy metal induced Parkinson’s disease. Methods: NNMT activity in supernatants separated from brain, liver and kidney homogenates of 5 elderly male Wistar rats by centrifugation were measured by high performance liquid chromatography system with fluorescence. NNMT activity under the conditon of 0.5 or 5.0 mM Mn2+, Fe2+, Cu2+ or Cd2+ was compared with control (no metal ion existence). Results: NNMT activities in rat brain, liver and kidneys were significantly decreased by Cu2+, and those in the liver and kidneys were significantly decreased by Cd2+. Mn2+ reduced NNMT activity only in the liver. Fe2+ had no effect on NNMT activity. Conclusions: No metal increased NNMT activity in this study, contrary to our hypothesis. Further study is needed to clarify the reason why the effects of Mn2+ and Fe2+ which have a high relevance to Parkinson’s disease on NNMT activity differ from those of Cu2+ and Cd2+

文部科学省の通達を受け,解剖学実習室におけるホルムアルデヒド対策について学生に周知させ,実習最終日に学生の防護具着用等に対するアンケート調査を行い,ホルムアルデヒド測定結果と合わせて今後の効果的な指導のあり方を検討した.遺体のビニールカバーを除去する前は0.02ppm以下と厚生労働省のガイドラインを下回っていたが,カバーと布を除去すると0.5ppmまで急上昇し,経時的には0.01～0.62ppmの範囲で変動した.ホルムアルデヒドの有害性について事前指導された学生の半数以上はマスクと手袋を常時併用していた.約60%の学生は実習中に眼の刺激感等の異常を自覚し,特にコンタクトレンズ使用者に多く認められ,眼鏡を使用している学生では眼の異常は認められなかった.ホルムアルデヒドの濃度低減には換気が第一であるが濃度モニタリングは必須である.又,学生にもその有害性を周知徹底させる必要がある
