    The effect of short-term feeding of various chlorophyll derivatives and its constituents was examined in rats maintained on diets containing 1% cholesterol and 0.25% bile salts. Cholesterol levels were determined in the serum and liver after 4 or 10 days feeding of each test substances at the 2% level.
    As for the results, the cholesterol content in the serum and liver was greatly reduced in rats given Na-Cu-chlorophyllin, K-Mg-chlorophyllin and Na-phytochlorin without delay of growth. In Na-Fe-chlorophyllin, cholesterol depressing effect was observed only in the liver, not in the serum. Inhibition of growth was also found to be specific to Na-Fe-chlorophyllin fed animals. Pyrrole showed no hypocholesterolemic activity.

    In the nicotinic acid supplemented rats, the uptake of 14C-tyrosine into brain was lower than that of the nicotinic acid deficient rats at 2 hours after the administration of 14C-tyrosine. The causes of decrease in the uptake of 14C-tyrosine into the brain by the administration of nicotinic acid to the nicotinic acid deficient rats was described in this paper.
    (1) The nicotinic acid deficient rats converted 14C-tyrosine more slowly to 14CO2 than the nicotinic acid supplemented rats. And the disappearance of 14C-tyrosine from serum was rapid by the administration of nicotinic acid to the nicotinic acid deficient rats.
    (2) Nicotinic acid caused no change in tyrosine concentrations in the liver. Therefore, increased production of labeled CO2 by the administration of nicotinic acid did not affect the dilution of the labeled tyrosine by cold tyrosine.
    (3) Tyrosine transaminase activity observed in the nicotinic acid deficient rats was lower than that of the nicotinic acid supplemented rats.
    Therefore, the increased activity of tyrosine transaminase in liver and the increased turnover of 14C-tyrosine in the body after the administration of nicotinic acid to the nicotinic acid deficient rats decreased the uptake of 14C-tyrosine into the brain.

    The high rate of children suffering from dental caries has become a social problem in Japan because of the bad effects which it brings about to their growth and health. In considering this, nutrition appears to have much importance in preventing dental caries.
    The present authors tried to investigate the relationships among the acceptance of vegetables, dental caries and the subjective symptoms of the digestive organs.
    The rate of the acceptance of vegetables was shown by the FACT scale (Food Action Rating scale) and the status of children suffering from dental caries by the def tooth rate.
    The results are summarized as follows:
    1) Those who suffered more from dental caries disliked vegetables (12 items out of 16 which were tested)in comparison with those who suffered less.
    2) A negative correlation was found between the FACT scale value of vegetables (6 items out of 16 which were tested) and the def tooth rate.
    3) Those who consumed sweets in between ordinary meals disliked vegetables and showed a high rate of dental caries.
    4) Those who often complained of subjective symptoms of digestive organs disliked vegetables.

    The balances of calcium, phosphorus and magnesium were studied in young rats, using a combination of magnesium and phosphorus at each level.
    The effects of changes in dietary magnesium on calcium and phosphorus balance was dependent on the dietary magnesium concentration. Increases in dietary magnesium reduced the apparent absorption of calcium and phosphorus and in respect of the fecal excretion rate a certain tendency was observed, namely high intake of magnesium seemed to induce an increase in phosphorus excretion as compared with calcium excretion. High intake of phosphorus lowered the apparent absorption of magnesium but did not affect the calcium balance.
