    The nutritive Status and intake of nutrients of farmers residing in Narita and Oyama Villages in the vicinity of Nihonmatsu City, Fukushima Prefecture was successively investigated twice, on September 1959 and February 1960, a number of 114 farmers serving as subjects. The subjects were instructed to take nutrients and drugs for a period of half a year between Sep. '59 and Feb., 60 and effectiveness of the above nutrients and drugs was investigated.

    It is reported that in Japan there are presumably 11.5 million households of widows with children who are living on the very low-income or live on government subsidy.
    To survey about their nutritional status is of an important significance for welfare as well as for their better nutrition.
    This report is about the results of a nutrition survey on mothers and children of such low-income in a certain institution in Tokyo.
    1) The nutrient intake: On an average, their nutrient intakes are poor, especially protein is inferior to that of all-Japan average both in quantity and in quality. The ratio of animal protein to total protein is low, and protein score is 72.
    Of all the nutrients calculated, calcium and vitamins are less than one half of the allowances.
    Since most of mothers are working out, they have little time for cooking, in their daily recipes cooked-foods sold at the shop are very often seen. Consequently the animal foods, especially meat, egg and milk are seldom used, and vegetables and legumes are also not enough ingested.
    2) Body measurements: Generally speaking, the mothers belong to the “lean type”, and the growth of school children is rather inferior. Especially their body circumferences (upper arm and chest) are of low values.
    3) Biochemical observations: Blood gravity and hemoglobin values are averagely low, and about 60% of the mother and 50% of the middle school pupils are under the normal range. The concentration of vitamins in blood and in urine (A, C, B1, B2, and N′-methyl-nicotinamide) are also remarkably low, and more than half of the mothers and about 30% of the boys and girls are in vitamin low level and deficiency.
    4) Clinical observations: Beriberi-like symptoms are remarkable, more than half of the mothers having such symptom, and about 73% are of malnutritional disease.
    5) As to their economical status, it was very difficult to obtain the exact information, but evaluating their expenditure on foods from the market price, it was 103.9 yen per adult per day. It is lower than all-Japan average. So-called Engel's coefficient was as-high as 88%, though it was evaluated from the presumed incomes.

    前報に示したとおり, 魚鯨肝油ビタミンAの生物効力は試料によつて種々の値を示し, 効力の大なものは全トランス型ビタミンAに匹敵するが, なかには相対生物効力にして70%を示すものもみられた。このような異同はマレイン価から推定しえたように, 種々の条件によって生ずる異性化によると考えられ, このような異性化は合成ビタミンAについても観察された。それらの結果はしろねずみの成長試験においても認められたが, その投与量によつて差異を生ずるような傾向がみられたこと, 既往の実験値は合成Aと天然Aとの効力が投与量の高い所で比較され, 且つ差異を生じていないことから, マレイン価と生物効力の関係をたしかめ, 飼料レベルに近い投与量でのビタミンA効力の比較を行つた。又相対生物効力によつてビタミンAの効力を示す場合これは全トランス型ビタミンAの効力に対する%で表わされるので, 種々得られた値を用いて, 一般測定に用いられる吸光法による測定値との比較検討を行つた。
    以上の結果より, 限界投与量においても, 非欠乏動物では合成ビタミンA油, 天然ビタミンA油のビタミンAの生長効力に差を生じないこと, 充分量の投与ではむしろ, 天然A油がまさること, マレイン価から推定した効力は, Ames らの値より10%程度大きいこと, 相対生物効力78%以上の魚肝油のビタミンA値は吸光分析値と一致することをみた。

    蛋白質, 肪肪の良好な給源である魚肉ソーセージに, ビタミンAを添加し, その製造工程中ならびに保存中における, ビタミンA値の変化を測定した。その結果, 添加したビタミンAは, 魚肉ソーセージ製造の, 蒸煮工程前に1部損失が起るものと思われるが, 蒸煮工程中に損失は起らなかつた。製品を7~9月に渉る72日間, 室温に放置したところ, 魚肉ソーセージ中のビタミンA値は, 約1カ月後においても, 製造直後と変化なかつた。しかし, 72日後においては, 製造直後の約70%に減少し, 味, 嗅等も相当変化していた。1方, 0~+2℃の冷蔵庫中に保存した場合におけるビタミンA値は, 72日保存後においても, 製造直後と変りなかつた。

    1. 食塩, 砂糖及び食酢の10%溶液に冷凍赤鯨肉 (10cm2, 厚さ1cm) をそれぞれ1時間浸漬し, 浸漬後21入鉄鍋中に11の大豆油を入れ, 170℃で4分間揚げ, 面積収縮率を求めてみると, 無処理油揚げ鯨肉で32.0%, 食塩浸漬で24.5%, 砂糖浸漬で32.1%, 食酢で30.1%となり, 食塩浸漬が最も防縮性効果があつた。
    2, 1, 5, 10%の食塩溶液にそれぞれ鯨肉を1時間浸潰し, 油揚げ鯨肉の収縮率及び消化性を調べた結果, 5%溶液以上では防縮効果は大きく, 消化性は10%溶液浸漬のものが最もすぐれていた。
    3. 10%食塩溶液に鯨肉を20分, 60分, 180分間ずつ浸漬し, 油揚げ後の収縮率及び消化性をみると, 浸漬時間の長い程, 防縮性にとみ, 消化性は浸漬時間とは関係なく凡そ一定であつた。
    4. 10%醤油溶液 (食塩濃度として1.8%) に鯨肉を1時間及び12時間浸漬し, 同様油揚げ鯨肉の収縮率及び消化性を調べると, 浸漬時間の長い程, 防縮性がよくなり, 消化性は1時間浸漬が最もわるかつた。

    Some kinds of water soluble fractions of soy bean oil meal were given as protein sources for the growth experiment of rats, and the results were compared with the data of soy bean oil meal fed rats.
    In experiment I, the results showed that both water soluble fraction of soy bean oil meal and the water soluble substance of the heated meal had less effect on the growth of the rats.
    In experiment II, it was demonstrated that weak heating of the extracted gels of soy bean oil meal gave a better growth in comparison of the growth of the unheated fraction fortified with DL-tryptphan.
    The residual fraction of the water extracted meal was most effective on the growth of rats, whereas the mixture of unheated water soluble fraction and the residual substances gave less effect on the growth of rats.
    The growth was markedly improved by enriching methionin to the unheated water soluble fraction of the meal.

    Dietary protein quality and quantity are characteristically reflected in the ratio of allantoin to urea. If the value of allantoin (A)/urea (U) ratio multiplied by the protein intake (Ip), (A/U)×Ip, is adopted considering the protein consumption at that time, this value falls into a certain constant point corresponding to the quality of protein used as a dietary ingredient, independently of varying the protein level or protein intake.
    In order to obtain more detailed knowledge on these phenomena, the present studies were carried out.
    When male adult rats of Wistar strain (370g) were fed on the diets incorporated egg albumin, casein, or wheat gluten at the levels of 10 and 25 per cent, (A/U)×Ip values were pursued.
    It was again found, as the results, that the values of the ratio of allantoin to urea multiplied by protein intake were not affected by dietary protein level or protein level or protein intake.
    Moreover, even immediately after the level of dietary protein was reduced from 25 to 10 per cent, these regularities were maintained.

    In this report, total riboflavin content and three different types of riboflavin contained in fresh eggs were measured. Riboflavin determination was carried out by the microriboflavin assay method of K. Yagi.
    Fish eggs, as fresh and mature as possible were collected from the fish market as Tsukiji in Tokyo.
    The results are shown in Table 1-3. The total riboflavin content of fresh eggs ranged from approximately 600γ% to 700γ% in the average.
    It was found that the percentages of three different types of riboflavin contained in fish eggs show the wide variations, but the great parts of riboflavin in fish eggs exist in the form of nucleotides, namely flavin adenine dinucleotide and flavin mononucleotide.
