In Japan, the decline in the age at menarche after the Second World War has been repeatedly reported, but the observed period in the reports has not been long enough to evaluate the secular trend of it. More than a hundred reports of age at menarche of Japanese have been published from the year of 1886. More than half of these populations in the reports consisted of students or young workers, some of whom had not attained menarche at the survey, and the menarcheal ages were represented by the arithmetric mean for the menarche attained girls. Thus, ages at menarche of these reports have biases toward younger menarcheal ages which depend on the proportion of non-menstruating girls. The authors aimed to correct these biased menarcheal ages on the assumption that (1) menarcheal ages of a population distributes normally when all of the girls are menstruating; (2) when some girls are not menstruating, the distribution is censored sample of normal distribution. After eliminating these biases of historical sources, the trend of the menarcheal age in Japan (from the late 19th century to the present) was analysed.

初経発来への年齢,身長,体重の寄与を,1960-64年に出生の女子生徒275名で調査した。初経時の年齢,身長,体重の平均値はそれぞれ12.5 SD 0.89年,151.1 SD 5.7cm,42.3 SD5.8kg であった。初経時年齢と身長は有意な正の相関(r=0.406)を示し,「初経時年齢群別の平均身長は一定値をとる」とした松林(1932)の報告は支持されなかった。初経時年齢と体重の間には関連がないが (r=0.104),初経時の体重は身長よりもはるかに大きな変動を示し,「特定の体重,体構成への到達が引き金となって初経が起こる」とした Frisch と Revelle(1971)の仮説も支持されなかった。さらに,各暦年齢時での初経の有無(1/0)を被説明変数,身長•体重を説明変数として重回帰分析を行なったところ,体重のみが有意な寄与を示した。この結果より,初経発来にかかわる体格の閾値の存在が示唆された。

マウスの飼育環境が,個体数増加や行動にどのような影響を及ぼすかを調べるため,実験室内でマウスを自由に繁殖させながら長期間飼育することのできる「populationcage」を製作した。「populationcage」は,openfield(1m×1.5m)とそれに接続した多数の小ケージとから成る。4週齢のICR系マウスの雌雄各4匹ずつを導入し,以後約20週間にわたって自由に繁殖させ,総個体数,性・年齢別個体数構成,出生・死亡数,及び種々の行動について観察を行なった。本研究においては,餌の供給量や居住空間を変化させ,個体群の大きさを制御する要因の解析や,密度増加に伴うマウスの行動変化等について検討した。餌を十分に摂取させた場合,総個体数の増加はほぼ直線的であった。その際,哺育仔総数の増加に伴い,他の哺育仔に押しのけられて授乳されずにいる新生仔の死亡率が著しく増加した。餌の供給量を制限した場合,マウスの総個体数は180匹に達して以降全く増加せず安定した。居住空間を様々な広さに変化させた場合,openfieldに出て来て授乳を行なったり,あたかも壁を越えようとするようにマウスが跳び上がったり等の特徴的な行動が観察されたが,それらの行動が初めて観察された日の個体数密度は,いずれの広さの場合においてもほぼ同じ値であった。

食材料 (生鮮67種, 加工・調理済70種) を一般市場より購入し, 某女子大生の食事記録に基づき83種の料理を作成した。これらの食材料と料理のセレン含量をWatkinsonの方法によって測定し, その値を文献値と比較した。これらの値に基づき, 食品群別セレン含量を定め, 国民栄養調査の結果 (昭和60年) を用い, 日本人1人1日あたりセレン摂取量を推定した。<BR>1) 生鮮食材料のうち高値を示したものは, 魚介類, 肉類, 卵類であった。文献値と比較すると, 生鮮, 加工両食材料ともにかなり食い違うものがみられた。<BR>2) 1人1回分の料理のセレン含量の大きかったものは, めん類, 卵料理, 肉料理, 魚介類の料理であったが, 料理のエネルギー含量100kcalあたりでみると, もっとも大きいものは魚料理であった。なお, 調理によるセレンの損失の可能性が一部の料理に認められた。<BR>3) 日本人1人1日あたりの推定摂取量は, 調理損失を考慮しないと, 104.2μgであった。

The gap between the accerelated physical growth and the stayed or relatively delayed mental development has become common in many countries. In this sense, the study on sexual maturation has to cover not only the physical but also the mental aspects. Age at menarche, the knowledge of sexual phenomena, and the behavioural pattern at counselling of sexual problems were the content of questionnaire. The subjects were girl students at Eiwa Junior and Senior High School in Yamanashi Prefecture. The results are summarized as follows: (1) Age at menarche has become younger annually. (2) Psychological reaction toward menarche differed dependent upon the age at it. (3) After menarche, students became more conscious to sexual phenomena, and tended to select persons other than parent as the counseller. (4) The amount of knowledge on sexual phenomena increased with the chronological age, but the understanding of underlying mechanism did not show a simply increasing pattern. (5) The age at menarche and the feeling invited by the menarche seemed to influence the increase of knowledge and the deepening of understanding. (6) By the content analysis of the answer to questionnaire, the development in intelligence was supposed to relate closely to the advancement of knowledge on sexual matters.

The record of family registration of 776 couples who were legally registered(HONSEKI) in Sendai city were analyzed. The couples whose grooms were born in 1926 and later who had got married between 1945 to 1974 in first marriage and who had at least two children were randomly selected from a regional frame in Sendai city. The period between the date of registration of wedding and that of notification of birth of first child is determined by the duration of de facto but not de jure marriage (NAIEN). In Japan the period of temporary informal marriage tended to be prolonged in many couples, keeping under the juridical and customary restraint, before the new civil law enacted 1948. The period between the date of registration of wedding and that of notification of birth of first child is determined by the duration of de facto but not de jure marriage (NAIEN). In Japan the period of temporary informal marriage tended to be prolonged in many couples, keeping under the juridical and customary restraint, before the new civil law enacted 1948. Though the majority of our samples had got married after the establishment of the law, some of them might do all that were required by the conventionalities. Under these social circumstances, our results of survey are as follows: 1) The intervals between date of registration of wedding and occurence of birth of first child of two age groups were compared with cumulative percentage of duration. The interval from registration of marriage to birth of the first child was shorter for the couples whose grooms were under age 25 at the time of wedding than those whosegrooms were age 25 and over throughout the observation periods. 2) When the couples were classified by the periods, 1945-54, 1955-64, 1965-74 of their date of registration of wedding, the said intervals had been prolonged through the descent periods successively. 3) In the form of notification of birth, it is requested to fill up the date of start of cohabitation. With the view of comparing the length of informal marriage, 352 notifications of first birth in 1974 were examined. Parents of these children were dwellers in Sendai city, and their fathers were born in 1926 and later. It was shown that the intervals from the beginning of cohabitation to birth in these 352 couples were longer than the intervals derived from the couples of legal registration(HONSEKI)
