    Lead, coproporphyrin and delta ALA concentrations in the urine of children who were exposed to different concentrations of lead in the atmosphere were measured every two months over a period of 12 months, from November 1970 to October 1971, and the results were satistically, examined.
    The subjects were 40 boys from a primary school in a rural area in Kanagawa prefecture and 40 boys from a primary school in downtown Yokohama. The atmospheric lead concentrations during the same period were also measured. Lead, coproporphyrin and delta ALA levels in the urine of school children exposed to different concentrations of lead in the air did not show any statististically significant variations through out the year of the study.

    (1) The effect of S-methylcysteine sulfoxide (Methiin) on anemia and splenic hypertrophy was compared with that of other sulfur containing amino acids. Male Wistar rats were separated into five groups of six each. Group A was fed a basal diet; group B, a 1% Methiin supplemented diet; group C, a 1% methionine-supplemented diet; group D, a 1% cysteine-supplemented diet and group E, a 1% S-methylcysteine (SMC)-supplemented diet. Diet were given ad libitum for 67 days. Spleen weight increased and significant anemia developed in rats fed Methiin, methionine and SMC-supplemented diet. No significant changes were observed in the cysteine-fed rats.
    (2) Similar experiments were repeated with a restricted diet and 4% levels of sulfur-containing amino acids. Addition of excessive doses of sulfur-containing amino acids resulted in a decrease of body weight in the early stages of the dietary regimens, after which growth gradually increased. Splenic hypertrophy as well as anemia were observed in the Methiin, methionine and SMC-supplemented groups; however the cysteine-supplemented group was normal.
    (3) To compare the effect of S-allylcysteine sulfoxide (Alliin) and Methiin, rats were separated into four groups of five animals each and the following synthetic diets were given as restricted diets for 21 days. Group A, a basal diet; group B, a 2% Methiin-supplemented diet; group C, a 2% Alliin-supplemented diet; group D, a 2% methionine-supplemented diet. In the Methiin- and methionine-supplemented rats, the spleen weight increased markedly, while rats on the Alliin-supplemented diet showed no such effect. A decrease of red blood cells, hemoglobin and hematocrit was also observed in the Methiin and methionine groups, while no anemia developed in the rats fed Alliin.

    Mercury pollution in the Minamata Bay and the Agano River area has been investigated mainly in respect to methyl mercury. In 1967, however, Kitamura et al. reported that the concentration of total mercury, methyl, and ethyl mercury in carp in the Jinzu River, Toyama, was 10.15, 0.53, and 3.00ppm, respectively. This was probably the first time that pollution by ethyl mercury was detected.
    The present report deals with a detailed survey of the mercury content (total, methyl, and ethyl Hg) of the adjacent soil, bottom sediment, and fish in the Jinzu River area, including several of its branches, conducted by the authors in 1969.
    The total and ethyl Hg concentration in fish was very high in the Kumano River (5.4 and 1.54ppm), a branch of the Jinzu River, and in the Jinzu-Ohashi area (2.8 and 0.69ppm), approximately 2km below the point where the Kumano River flows into the main stream. This led us to examine the drainage of “F” pharmaceutical factory into the Kumano River. Our first hypothesis that the pollution might be of geochemical nature was proved wrong by the finding that the total and ethyl Hg concentration in the sediment in this drainage was extremely high, 9, 300 and 31.90ppm, respectively.
    These results clearly indicate that the pollution originated from “F” pharmeceutical factory, where thimerosal was being produced.

    The accuracy of the Lawther & Apthorp method with a non-dispersive infrared analyser was investigated for use in the determination of carbon monoxide in the blood.
    The Horvath & Roughton method and the Commins & Lawther method were selected for manometric and spectrophotometric determinations respectively.
    The accuracy of the manometric method was found to be lower than that of the other two methods, while that of the spectrophotometric and infrared methods was about equal. Infrared method was excellent in respect to both its accuracy, especially at low CO concentrations, and its simplicity.
    The Lawther & Apthorp method can therefore be recommended for the determination of blood CO in studies of airpollution.

    Rice samples were collected from 77 farm-houses in and around the district where“Itai-itai”disease is endemic.
    The Cd concentration of rice samples collected from the endemic district was higher than that in those from non-endemic district, moreover, within the endemic district the Cd concentration in rice from the most highly endemic areas was higher than in that from other parts of the district.
    High correlation coefficients were observed between Cd concentration in rice field soil and that in rice, and also between Cd levels in the rice and the urinary abnormalities of the inhabitants.
    In the endemic district, the Cd content of rice collected from the farm-houses where family members had a high incidence of proteinuria was higher than that from farm-houses where the family members had no proteinuria.
    It was concluded that Cd in rice is one of the health hazards in this district.

    The purpose of this paper is to make clear a comprehensive relationship between two groups of measurements of blood pressure and physical constitution. The first group of measurements include pulse rate, systolic blood pressure and diastolic blood pressure, and the second group of measurements include height, weight, chest circumference, circumference of the upper arm and sitting height.
    These figures are taken from the Nutrition Survey of Japanese, including 6617 males and 8909 females, investigated in May, 1961.
    Appling the canonical correlation analysis, we found the following results.
    1) Only two canonical correlations were statistically significant.
    2) The value of the first canonical correlation was 0.262 for males and 0.381 for females. The corresponding canonical variables were considered as a blood pressure factor and a physical type factor, respectively.
    3) It seemed that, as the physical type factor changed with age, the blood pressure factor also changed proportionately.
    4) The value of the second canonical correlation was rather small but significant, 0.094 for males and 0.108 for females. The corresponding canonical variables seemed to be a pulse-pressure factor and a second physical type factor related to weight (positive) and chest circumference (negative).
    5) In addition, it was also found that the pulse rate has little to do with the physical type.

    The levels of street noise in 132 places in Karatsu City were measured in order to determine the actual state of city noise.
    1) The mean noise levels in dB (A) of each area in the daytime and at night, classified according to the type of neighborhood were: Commercial (69 and 59dB)>industrial (60 and 53dB)>and residential (53 and 43dB).
    2) The mean noise levels in dB (A) of each area in the daytime and at night, classified according to width of road were: Over 10m wide (69 and 64dB)>5-10m wide (63 and 56dB)>3-5m wide (54 and 44dB)>and under 3m wide (46 and 42dB).
    3) There is a positive correlation between the street noise levels (LM) in dB (A) and the logarithm of the number of cars (N per hour). The correlation coefficient was r=0.89 and the regression of LM on log N was LM=17.7 log N+15.1.

    The community reaction to city noise was investigated by questionaires in Karatsu City.
    1) The intensity of the community's reaction to street noise, classified according to type of district and width of road was: Commercial>industrial>residential district: and Two-lane road (over 10m)>one-lane road (5 to 10m)>alley (under 3m in width).
    2) The intensity of annoyance reaction to street noise increased markedly when the noise level reached 60dB (A) or more during the daytime and 45dB (A) or more at night.
    3) In order to sleep, one often tries to move one's bed to a room as far from a road as possible. This study shows, however, that this kind of easy defensive measure is not effective when the street noise level is raised to 60dB (A) or more by heavy traffic at night, given the present architecture of Japanese houses.
