    The sociometric status of children with attention deficit disorder (ADD) was surveyed in order to determine peer popularity among school children. Sociometric tests were conducted in 28 classrooms which included ADD-children, and sociometric indicators of ADD-children were compared with those of controls who had been randomly selected after being matched to ADD-children by age, sex and classroom.
    The results were as follows:
    1. ADD-children received significantly more Social Rejection votes and significantly fewer Social Choice votes than controls. They had a small Mutual Choice number than controls.
    2. The index of sociometric status score (ISSS) of ADD-children was significantly lower than that of controls.
    3. The low sociometric status of ADD-children correlated with i) higher grade in school, ii) later first counseling, iii) hyperactive type, iv) lower IQ levels, and v) no history of pharmacotherapy with methylphenidate.
    4. There was no relation between the sociometric status of ADD-children and the group cohensiveness of the classroom.
    5. Seventy-one percent of ADD-children were assessed by their parents as having problems in human relations. But those assessments had no relation to the sociometric status of ADD-children.

    Nitrogen dioxide is one of the most important indoor air pollutants which can be generated from sources inside the private home and is one of the criteria pollutants for which ambient air quality standards have been promulgated. Investigation of the relationship between indoor and outdoor levels of these pollutants is important for epidemiological studies on the adverse health effects of air pollutants.
    Simultaneous measurements were made of the concentrations of nitrogen dioxide (NO2) and nitrogen monoxide (NO) for a year at a home in Tokyo. It was seen that indoor NO levels roughly corresponded to those of outdoors over the long-term. In regard to diurnal variations, two peaks were observed, i. e., in the mornings and in the evenings, for indoor and outdoor levels of NO. The long-term and the diurnal variations of indoor NO2 levels were different from those of outdoor NO2 levels. It was shown that the relationships between indoor and outdoor NO2 concentrations varied seasonally. There was not a close correlation between the daily average of indoor NO2 concentrations and the daily maximum of hourly indoor NO2 concentrations. Thus it appears to be difficult to estimate the peak levels of indoor NO2 from daily average concentrations.

    The effects of Cadmium (Cd) on the contraction of vascular smooth muscle induced by high potassium (K+) solution and norepinephrine (NE) were investigated in this study. In particular, the effects of low doses of Cd at environmental exposure levels (0.1-10μM) were studied. We used the metheod of tissue culture for exposure of Cd to renal arteries of rabbits for 3 days. Before studying of the effects of 3-day Cd exposure, the contractions of nonincubated arteries and of arteries incubated without Cd were also investigated.
    The results are as follows:
    1) The resting tension of non-incubated renal arteries was not affected by 0.1-200μM Cd. However, the contraction induced by K+ or NE was reduced by 100-200μM Cd.
    2) The contraction sensitivity of renal arteries to NE gradually increased during the incubation period (‘supersensitivity’). These effects were maximal after 3 days of incubation. However, incubation was not affected by contraction induced by K+. Two hundred μM Cd reduced the contractions of incubated arteries induced by K+ or NE.
    3) The addition of Cd (1-10μM) to the medium inhibited the development of supersensitivity of renal arteries to NE. However, Cd did not affect the contraction of incubated arteries induced by K+.

    The concentration change of suspended particulate matter (SPM) in indoor and outdoor air environments was studied. Since the respiratory absorption of particles is markedly different according to their size, a new personal sampler (SPMP-sampler) was made. The sampler could collect particles above 10μm, 2 to 10μm, and below 2μm in aerodynamic diameter separately. SPM concentration using the SPMP-sampler was almost linear to the results of using a Marple Personal Cascade Impactor. The linear equation was
    y=0.976x+3.88(μg/m3)(r=0.95)
    where x and y are the SPM concentration measured using the SPMP-sampler and the Marple Personal Cascade Impactor, respectively.
    The SPM concentration in a main crossroad air environment changed rapidly. The SPM concentration in the outdoor air environment of the residential areas near the crossroad was greatly reduced compared with the crossroad, but still much higher than in rural areas. The relationship between the particle concentration in indoor and outdoor air environments varied with the diameter of the particles. The SPM concentration in the indoor air environment linearly increased according to the increase of that in the outdoor environment.
    The polycyclic aromatic hydrocarbons (PAH) concentration in particles also changed sharply depending on their diameter. Fine particles below 2μm in diameter had a high PAH concentration.

    The selenium (Se) concentrations in adult whole blood were determined for 331 healthy subjects living in Nagano Prefecture. Then the Se concentration, the distribution, the physiological value, the relationships to increasing age and coexistent elements (K, Na, Mg, Ca, Fe, Zn) were studied. The mean±standard deviation of Se levels obtained was 157±37 (ng-Se/g-blood) for males, and 156±32 (ng-Se/g-blood) for females. The data showed logarithmic normal distributions in both sexes. The normal range of Se concentration was 100-240 (ng-Se/g-blood). No sex difference in concentration was noticed for any subjects. The concentration for males in their twenties, however, was higher than that for females.
    Se concentrations in whole blood decreased with increasing age in the ratio of 0.8 (ng-Se/g-blood) to one age. Significant correlations between Se and K, Fe, Ca, Mg, and Zn were noticed.

    To clarify the health and nutritional status of inhabitants of rural Thailand, a medical survey study was carried out in a farm village with a population of about 1000 in northeast Thailand (near Kohn Kaen: Don Daeng village) in 1984 and 1985. In this report, the physical growth status and biochemical blood status of school children are presented.
    All physical parameters, i. e., body height, body weight, girth of chest, and skin fold thickness, were poor as compared with recent Japanese children (those of school children in the village are almost the same as those of Japanese from 1950-1955).
    From plasma and blood examination, the spread of infectious diseases including chronic hepatitis was presumed, and the nutritional status of protein, fat, vitamins and minerals was insufficient as compared to Japanese children. Therefore, it is postulated that there were many marginal nutritional deficiencies, i. e., thiamine, calcium, iron, etc. and that many diseases will be induced by these nutritional deficiencies.

    Urine samples were collected from 3178 inhabitants of the Kakehashi River basin, an area exposed to Cd, and 294 nonexposed inhabitants of Ishikawa Prefecture. All subjects were over 50 years old. The samples were analyzed for protein, glucose, amino acid, β2-microglobulin and Cd.
    The mean urinary concentrations of these parameters were higher in the Cd-exposed subjects than in the nonexposed subjects.
    The concurrent prevalences of proteinuria and glucosuria, as well as those of aminoaciduria and β2-microglobulinuria were higher in the Cd-exposed subjects than in the nonexposed subjects. β2-microglobulin was considered to be the most useful indicator of the renal effects of Cd exposure.
    In the Cd-exposed subjects, the prevalence of, β2-microgloburinuria was higher in those who ate Cd-polluted rice than in those who ate unpolluted rice.
    Among them, the prevalence of β2-microgloburinuria increased in men living in the polluted area for over 60 years and in women living there for over 40 years.

    In order to examine the actual conditions of air pollution by suspended particulate matter (SPM) due to diesel exhaust, traffic characteristics, weather conditions and SPM concentrations were measured in the vicinity of Kusatsu Parking Area (Kusatsu P. A.) which is located between Ritto Interchange (Ritto I. C.) and W. Seta I. C. on the Meishin expressway. Concentrations of gaseous pollutants, were also measured in this 24 hours survey which was performed three times at 7 points simultaneously. The results obtained were as follows;
    1) The total-traffic volume in this section was about 60000/day and the constitution ratios of large vehicles which had diesel engines were higher at night (6 p.m. to 4 a.m.) than in the day, the former ratio was 80 to 90% and the latter was 45 to 50%.
    2) In the first survey, the concentration of SPM was about 250μg/m3, a figure derived by the sum of the values in the fractional collection at the roadside. The size distribution curve of SPM showed two peaks; the first was in the fraction below 0.7μm and the second was at about 10μm. From the roardside to about 300m the SPM concentrations decreased with distance from the source of pollution, and the fraction below 0.5μm, which has a directly influence on human health, was above 70% in the particle size distribution at every point.
    3) Daily average values of carbon monoxide (CO) and hydrocarbons (HC as methane) were in the range from 2.0 to 2.2ppm for CO and 5 to 6ppm for HC at the roadside.
    4) Daily average values of nitrogen oxides (NOx) were in the range from 16 to 77ppb for nitrogen monoxide (NO), 19 to 37ppb for nitrogen dioxide (NO2) and 39 to 120ppb for NOx at the roadside, while, the hourly values of NO2 rose rapidly with the increase of traffic volume, 90 to 120ppb of NO2 being measured from 10 to 12 a.m. when the traffic volume was at its maximum.

    To investigate the mechanism of the occurrence of peripheral circulatory disturbances in the Hand-Arm Vibration Syndrome, serum Ca and Mg in workers using vibrating tools were measured. Serum Mg levels in workers with Raynaud's phenomenon were significantly lower than those in workers with no symptoms. Serum Ca/Mg in workers with Raynaud's phenomenon was slightly higher than that in workers with no symptoms. Fingertip skin temperature, which is the index of peripheral circulatory disturbances, in workers with Raynaud's phenomenon was slightly lower than that in workers with no symptoms. These results suggest that there are some relationships between the decrease of serum Mg and the increase of serum Ca/Mg, and the occurrence of peripheral circulatory disturbances in the Hand-Arm Vibration Syndrome.

    The nutritional availability of selenium (Se) contained in rice was estimated by measuring the tissue Se levels and glutathione peroxidase (GSH-Px) activities of rats fed a diet consisting of 90% brown rice. Male weanling rats were fed a casein-based diet (diet A) or, the casein-based diet supplemented with 0.05 or 0.10μg Se/g of selenite (diets B and C, respectively), a low-Se rice-based diet (diet D), or a high-Se rice-based diet (diet E) for 4 weeks. Dietary Se levels measured by fluorometrical analysis were as follows (ng Se/g): A, 18; B, 65; C, 118; D, 24; E, 62. The selenite added to the casein-based diets dose-dependently increased the Se levels and GSH-Px activities in the blood and liver of the rats. The tissue Se levels and GSH-Px activities in the rats fed the rice-based diets (diet D or E) were comparable to those in the rats fed diet A or diet B, respectively. The nutritional availability of rice-selenium, estimated by using the general equation: GSH-Px activity or tissue selenium level=m×log (dietary selenium level)+k, was 65-107% compared to selenite.

    The surveillance of infectious diseases is currently carried out in Japan by a monitoring system, in which there are week reports from selected clinics. The effectiveness and reliability of this system is dependent largely on the number of clinics.
    The data on eight common pediatric infectious diseases such as chicken pox, mumps and infantile diarrhea collected during a four-year period by clinics was analyzed to evaluate the surveillance system in the city of Kyoto.
    1. Reported cases of the eight diseases showed high variations among clinics. The correlation between two of the eight diseases was high in the case of chicken pox and mumps, but low in others, for example chicken pox and summer cold.
    2. The characteristics of a clinic could not be grouped according to the number of cases, areas or branches of clinics by multivariate statistical analysis. Therefore, each clinic had individual significance for the surveillance program.
    3. In each disease, the average and the standard deviation of the weekly reports over a period of four years covering Japan were used as indices which were thought to indicate the degree of accuracy. Consequently, the number of clinics necessary for surveillance was considered to be 30 in Kyoto (population of 1, 479, 000), with the population of residents per clinic being 49, 000, which was nearly equal to the standard number proposed by the Ministry of Public Welfare.
    4. In order to ensure both accuracy and effectiveness of surveillance, a larger number of clinics is needed for monitoring a total of 21 diseases.
