    Polluted brown rice containing 0.6ppm of cadmium which is under the limit of the safety standard (1.0ppm for brown rice and 0.9ppm for polished rice), was investigated for the effects on animal organs. The above standards have been set by the Ministry of Health and Welfare, Japan.
    87 mice were divided into four groups with diets as follows:
    Group 1. unpolluted brown rice (0.1ppm cadmium) and low calcium content.
    Group 2. unpolluted brown rice with high calcium content.
    Group 3. polluted brown rice (0.6ppm) and low calcium content.
    Group 4. polluted brown rice with high calcium content.
    After 75 weeks on these dietary regimens the animals were sacrificed and livers and kidneys were determined for cadmium content. The atomic absorption method was employed.
    Results: Average content of cadmium in kidneys of the respective groups was: 3.46, 1.14, 10.40, 6.90ppm (dry matter). In the livers 0.72, 0.17, 2.27, 1.50ppm.
    It was thus demonstrated that cadmium content in animal organs increased remarkably on a polluted rice diet especially in the food with low calcium content. Cadmium accumulated considerably in mice that lived throughout the entire experimental period.

    25 geriatric persons and 20 control subjects (young adults) were divided into 5 groups respectively and maintained on experimental diets about 12 weeks. The total caloric intake was 2, 500Cal/day for young adults and 2, 100Cal/day for the aged. Protein intake was 70g/day for all subjects. Fat intake for young adults and the aged was respectively as follows:
    Group I (Similar to daily Japanese diet), 45g/day, 35g/day; Group II, 65g/day, 55g/day; Group III, 85g/day, 75g/day; Group IV, 105g/day, 95g/day; Group V, 125g/day, 115g/day.
    Butter was utilized at the dietary fat.
    No remarkable effects were seen in Group I, II and III in young adults and Group I and II in the aged.
    Some persons of Group IV and V in young adults and Group III, IV and V in the aged showed hyperlipidemias and changes in the fatty acids compositions of serum lipids. Some persons dropped out of the experiment for reasons, such as pyrosis, nausea, anorexia and fatty diarrhea.
    It is suggested that the Japanese diet should include 25 to 30 fat as a source of energy, but less than 25% for aged persons for the present.

    The amount of uranium in the daily diet and human urine was measured by means of solid fluorimetry and the accuracy of this test was established.
    Recovery of the dietary uranium was 52.61±4.34% at the 95% confidence level. As the coefficient of variation was small, it was concluded that this method can be used for the measurement of dietary uranium.
    Recovery of human urinary uranium was 87.72±1.88% at the 95% confidence level.

    Daily dietary intake of uranium was measured in persons living in the vicinity of a uranium mine and refinery.
    No seasonal variations were seen in uranium intake, however a significant difference (P=0.01) in uranium intake was seen between the test and control villages and significant differences were seen among three test villages.

    Uranium excreted in urine from non-occupationally exposed persons was measured by means of solid fluorimetry. Subjects were residents of three villages in the vicinity of auranium mine and refinery in Okayama, Japan, and one village in Okayama served as the control village.
    Significant differences in the urinary excretion of uranium were noted among all the test villages as well as a comparison to the control.

    The mean of the dietary intake of uranium in the region of a uranium mine was 3.190-9.150μg/day/person, while that in the region of the control was 1.771μg/day/person.
    The mean of the urinary excretion of uranium was 0.027-0.147μg/day/person in the test areas and 0.006μg/day/person in the control area.
    When the dietary intake (xμg) was within a range of 1.771-9.150μg/day/person, x was related to the urinary excretion (yμg) as follows;
    y=(0.00274)x1.71

    The experiment was carried out in order to evaluate the drunkenness due to objective alcohol consumption.
    Twenty three healthy Japanese male adults were provided with 540ml of Japanese Rice Wine, which was consumed in 30min. before the evening meal. The TAF test, electroencephalography (EEG) and microvibration recording (MV) administered to the examinees at 10a.m. (control value), before drinking (pre-value), and 10 and 50min, after drinking (post-value). The EEG lead from the occipital area to the right ear, and MV lead from the left thenar, were analyzed in δ (2-4c/s), θ (4-8c/s), α (8-13c/s), β1 (13-20c/s) and β2 (20-30c/s) waves.
    Results are as follows:
    1. TAF-L at 10 and 50min. after alcohol drinking lowered significantly.
    2. In EEG at rest, the β1 wave showed a significant increase 10min. after alcohol intake. In EEG during TAF-test, the δ, β1 and β2 waves decreased significantly 10min. after alcohol intake, and the δ, θ, β1 and β2 waves also decreased 50min. after alcohol intake.
    3. Fifty minutes after alcohol intake a significant correlation between lowering of TAF-L and decrease of α wave in EEG was recognized, and an increase of θ wave in EEG was seen in each of 14 of the 18 examinees with a lowering of the TAF-L.
    4. Due to alcohol the β1 and β2 waves of MV at rest increased significantly, and the α wave of MV during TAF test decreased significnatly 50min. after alcohol intake. Comparing MVs at rest and during TAF-test, all waves of control and before alcohol intake of the latter showed significant increases, while the δ, θ, β1 and β2 waves during TAF test at 10 and 50min. after alcohol intake increased significantly, but the α wave showed no significant change.
    These results prove that cerebral activities are lowered as a result of alcohol intake and showed that drunkenness can be diagnosed according to function of the concentration maintenance (TAF) as a performance test.
