ジャーナル フリーPCBを投与した動物の成長および脂質代謝が飼料中のV. Dの有無によってどのような影響をうけるかについて検討した結果を要約すると次の如くである。
1. 飼料中にV. D2が不足しても, またある一定量以上添加してもPCBによる成長抑制が一層著しく, 毒性の強まることを認めた。
2. V. AはPCBによる成長抑制を改善する効果を有することを再確認した。
3. PCBを含む飼料にV. D2 1,000 IUとV. A 3,000IUを同時に添加した場合, V. AはPCBによる成長抑制を改善する効果を示さなかった。
4. PCBを含む飼料にV. D2 1,000IU添加した場合は血清の中性脂肪と燐脂質を著しく増加させた。抄録全体を表示PDF形式でダウンロード (6266K) -

ジャーナル フリーPhe 過剰投与による肝Phe H活性低下の原因を検討し, 次の結果を得た。
1. 数種の Phe 中間代謝物が Freedland 法によるPhe H活性測定におよぼす阻害の影響を調べ, PPAが強い阻害を起すことを認めた。またシロネズミにPPAを投与しても Freedland 法によるPhe H活性の低下を見た。
2. Freedland 法 medium にPhe Hの補酵素であるH4Ptを添加することにより, PPAのPhe Hに対する阻害はPhe H活性の絶対値の上昇とともに減少した。また, Phe過剰投与シロネズミの肝上清のPhe H活性測定の場合でも似たような現象を示した。
3. 5% L-Phe飼料投与シロネズミは尿中に多量のPPAを排泄したが, この場合の肝Phe H活性は Freedland 法では低下した。medium にH4Ptを添加すると対照との差は相対的に少なくなった。5%D-Phe 投与の場合もPPAの排泄が異状に増加し, Phe H活性が低下したが, これもH4Ptし添加により対照と似た値になったので, 測定時にPPAが阻害していたものと考えた。抄録全体を表示PDF形式でダウンロード (10313K) -

ジャーナル フリーSince the relationship between food preference and regional difference seen in middle school girls has not yet been known enough, this study was made for the purpose of making it clear the difference between food preference, father's occupation, and food intake of middle school girls.
The subjects were 856 girls in the middle school in two districts, Yamagata (Northern Japan) and Saga (Southern Japan) for this study. The age of the girls were 14.
The results obtained were as fallows.
1. Significant difference was not observed in obesity rate (Yamagata 14.6%, Saga 10.9%)
We adopted Dr. Hibi's Method (1972) in judging obesity. Girls weighing over 120% of their standard weight were judged as obese.
2. The rate of taking breakfast (Yamagata 84.3%, Saga 78.9%) was not related with obesity rate and regional difference was not seen in the breakfast taking rate.
3. There was no relation between obesity and midnight meals.
4. Preference of some food (egg, pork, cow's milk, sausage, salted fish gut, pickled plum, chocolate, ice-cream, bean-jam bun) had no relation with obesity, but regional difference was observed.抄録全体を表示PDF形式でダウンロード (7914K) -

ジャーナル フリーIn Japan, districts of longevity have become the object of academic study since 1950. However, owing to the recent economic developement, the population and habits in these areas have been drastically changed. Moreover, in 1975, average life expectancy of Japanese people reached 71.76 (male) and 76.95 (female) years old. Thus, it became necessary to survey these districts in mountains, rice fields, isolated islands and seasides. The age of all centenarians in the areas was confirmed by the official birth record (Koseki). Population of old men and women in each area in Feburuary 1976 was listed. Most of the islands and seasides were visited during June, 1976. The results were as follows:
1. In every area except Nishinoshima (Shimane), Ishii and Aizumi (both are close to Tokushima city), the percent of inhabitants over seventy years of age has been increased since 1950 (Table 1). The highest figures (male 12.1%, female 19.6%) were observed in Ohgimison (Okinawa) as contrasted with 3.9% (male) and 5.3% (female) of the average Japanese (Table 2). The emigration of young population (maximum 30% per 5 years) was observed in every area except Ishii and Aizumi (Table 3).
2. The percent of inhabitants over ninety years of age was 0.19 (male) and 0.23 (female) in the mountains, 0.06 and 0.20 in the rice fields, 0.24 and 0.72 in the islands and 0.25 and 0.61 in the seasides. Ohgimison had the highest figures (male 0.4%, female, 1.3%) with population of 4, 126 including four centenarians. The eldest person in Japan was 112 years old. Most of these old people in the areas were hypertensive and their diet habits in their youth were characteristic to each area (Table 4). Otherwise, their case histories were similar to the reports on average Japanese centenarians (1975, male 157, female 651), and they had long-lived parents or close relatives.
3. The diet and life style of these old people (Table 4) and all inhabitants (Table 3) in these areas have changed completely. Instead of barley (most of the area) or sweet potatoes (Okinawa) taken in the past, rice became the major diet in every area. Characteristic diet in each area was lost except Okinawa. Of all working population in these areas, percentage of fishermen and foresters decreased (20 to 60%). Ten out of sixteen areas became resorts.抄録全体を表示PDF形式でダウンロード (12456K) -

ジャーナル フリーThe subjects, whose daily nutrient intake is under the Dietary Allowances, have been indicated as being undesirable nutritures on the basis of the data concerning food intake investigations. But, these indications are merely based on the comparisons between the food intake and the Dietary Allowances.
Hereupon, in order to confirm whether the nutritures of young women (college students) who are in these situations are inadequate or not, each caloric intake and fluctuation of body weight were examined every day through a week in three seasons (April, June, and August).
It was found that though their caloric intakes were lower than the Dietary Allowances, their body weight were constant and they could engage in full activities.
The authors assumed that these situations need no apprehensions.抄録全体を表示PDF形式でダウンロード (5871K) -

ジャーナル フリー生後10週齢の雄成熟白ネズミに牛乳力ゼイン15%を含む半合成飼料を与え7週間飼育した。飼育後4, 5, 6, 7週毎に殺して盲腸内容物をとり出し, 内容物中の総窒素濃度, 揮発性塩基性窒素濃度, 尿素分解活性を測定した。
その結果, 盲腸内容物の (1) 総窒素濃度は動物の飼育期間が長くなるにつれて上昇した。(2) 揮発性塩基性窒素濃度は飼育期間中ほとんど変化しなかった。(3) 一方, 腸内微生物由来であることが知られている尿素分解活性は, 飼育期間が長くなるにつれて上昇する傾向を示した。
これらの結果から, 盲腸内容物の揮発性塩基性窒素濃度は, 総窒素濃度と必ずしも直接的な関連がないことを認めたが, 尿素分解活性との間にも必ずしも関連のないことが認められた。抄録全体を表示PDF形式でダウンロード (4765K)
