The authors investigated the effect of Trp level with or without niacin (NiA) in a diet on growth of young rats and amounts of excretion into urine and contents of liver of Trp metabolites (quinolinic acid, NiA, N^1-methylnicotinamide and NAD) . The additional effect of NiA (0.003%) was observed only at Trp level 0.043% but not at 0.085, 0.17, 0.25 and 0.34% in the diets, from the result of gain in body weight and protein efficiency ratio. However, from the results of excretion and amounts of liver of Trp metabolites, the additional effect of NiA was observed not only at Trp level 0.043% but also at 0.085%. Therefore we presume that 0.085% of Trp in diet may be the point whether the additional effect of NiA is observed in young rats or not. Since Trp metabolites in liver increased depending on Trp content in the diet at the first-order reaction, the biosynthetic ability of NAD by rat liver from Trp would be fairly active. If Trp intake is higher than from that of the body protein requirement, NAD needed to all other tissues of rat would be furnished by the liver from excess amounts of Trp.

A survey on nutritional status of vitamin B_1 in adults of two villages with insufficient medical care in Shimane Prefecture was carried out in 1978, 1979 and 1980. The results of the survey were as follows: (1) Thiamin level and transketolase activity in blood were very low and the thiamin pyrophosphate effect was high. (2) Urinary thiamin excretion (24 hours urine and urine of a single excretion) was also very low. Urinary thiamin contents were good correlation with γ=0.84 between 24 hours urine and urine of a single excretion. (3) The thiamin intake analyzed with their foods was, on the average, 0.53 mg/day and that calculated from hearing nutritional survey was 0.69 mg/day. In these areas, thiamin intake seems to be insufficient. (4) In a consequence of intake of thiamin fortified rice (1.5 mg/day), blood thiamin level, transketolase activity and the urinary thiamin excretion were increased, and pyrophosphate effect was decreased. An improvement of vitamin B_1 nutritional status was observed.
