    This paper is concerned with studying the developmental changes which occur in sensitivity to the 4 primary taste qualities viz. sweet (sucrose), sour (citric acid), bitter (quinine sulfate) and salty (sodium chloride).
    Results are as follows:
    1. Taste threshold values and difference threshold values for the 4 taste qualities increased with age and showed a peak at the age of 60. These values slightly decreased at the age of 70.
    2. An increase of salty taste threshold values with aging were more marked than other taste threshold values.
    3. Either sex failed to reveal significant differences for taste sensitivity.
    4. Significant differences in taste threshold, especially bitter taste, were observed between smokers and non-smokers.
    5. False dentures (complete) appeared to influence slightly taste threshold values.

  • (I) Effect of Increased Dietary S-Methylcysteine Sulfoxide on Growth and Tissues in Rats

    S-Methylcysteine Sulfoxide (Methiin) is distributed abundantly in Liliaceae (garlic, onions etc.) and Cruciferae plants (cabbage, radish etc.) and is one of the greater sources of sulphur containing amino acids in Japan. The effect of increased doses of dietary Methiin in rats is described herein.
    A 2% Methiin supplemented diet was administered at libitum to Wistar rats for a 74 day period. This resulted in a slow down of growth although decrease in food intake also played a role. Extra intake of Methiin resulted in an increase in splenic iron as well as a decrease in the erythrocyte counts.

    The following is part of a series of studies on nutritional values of S-Methylcysteine Sulfoxide (Methiin), a sulphur containing amino acid extracted from cabbage. The present paper describes rat response to large doses of Methiin as follows:
    (1) Addition of excessive doses of Methiin (4%) to the diet resulted in splenic hypertrophy and anemia. When the Methiin containing diet was reversed to that of basal, splenic hypertrophy and anemia disappeared within a few weeks.
    (2) Excessive dietary administration of Methiin to a group of splenoectomized rats resulted in a decrease of erythrocyte counts, haematocrit and haemoglobin.

    Health examinations were undertaken to determine health hazards of lead and cadmium on painters in the ceramic field. 283 persons were examined regarding lead and cadmium concentration in urine, protein and glucose levels in urine as well as hemoglobin and hematcrit levels.
    Results are as follows:
    (1) Concentration of lead in the urine from painters was higher than that of non-painters and 6% were above 150μg/L.
    (2) It was found that the lead decreased blood hemoglobin and hematcrit levels even when the greater part of lead concentration in urine was under 150μg/L.
    (3) In the group where both lead and cadmium concentration in the urine was high, hemoglobin and hematcrit levels decreased considerably making recognizable the fact that lead and cadmium result in considerable co-operative injury on the blood.
