    体位血圧反射の体質検査法としての価値を検討するために,健康男女日本人各10名につき,本反射の逐日的観察を行い,次の諸点を明らかにした.
    (1)月経中及びその前後を除けば休位血圧反射には男女開に特異を認めない.
    (2)疲労,睡眠不足等のない場合には,体位血圧反射の血圧回復曲線ば指数函数的或はこれに動揺反復を加えた型式をとり,多くは回復時問は1分以内であり,これに逐日的な著しい変異を認めない.
    最小血圧は一般に変化少く,且つ逐日的変化も少い.脈圧は坐位転換後1分以後で初めの95%以上に回復し,逐円的変化は少い.最大血圧の一過性拍1圧降下度は10mmHg以下であり,逐日的に特異な変化は認められない.
    (3)疲労,睡眠不足等のある場合には,反射性血圧回復の不全性があらわれ,回復時開の延長が見られ,且つ一過性血圧降下度の増大,血圧動揺の増加が認められる.
    休位転換の際ひき起される体位血圧反射により,転換後の血圧が再びもとの水準に調整される自律紳経系の働きは,ここに逐日的観察を行つた男,女各10名の被検者に於ては健康な個休に保持されている性質であることを示した。その調整能は睡眠不足,疲労その他の違和に伴つて一過性に多少おかされることはあつても,まもなく回復する.したがつてこれを一般的に健康体の体質の標徴とすることができる。何等の訴えのない一見正常な健康者でつねに調整不全を有する個体が果してあるか否かは今後の調査にまたなければならない.

    1. The author calculated the ratio of enlargement applicable to conversion of the short distance roentgenogram, shch as taken from the fluoroscopic image, into a picture that practically corresponds to an orthodiagram or tele-roentgenogram.
    If a cone of rays originating from a point source on the z-axis of the three-dimensional rectangular Cartesian coodinate system cast a shadow of a sphere with the center on the z-axis upon the x-y plane, the distance from the z-axis of any point (x, y) on the optical edge on the sphere is expressed by. √x2+y2. Let the “focal” distance onto the fluoroscope be F; the angle between the z-axis and the ray touching the sphere at the point (x, y) be. θ, and the fluoroscopic image corresponding to thelength. √x2+y2 cast on the x-y plane (represented by the fluoroscope) will be F tan. θ. Thus the ratio of magnification, M, is
    M=F tanθ√x2+y2
    The author theoretically showed applicability of this formula.
    2. A model of the heart was cut out from diatomaceous earth (Kieselguhr), and the applicability of the above formula was tested with satisfactory result.
    The actual site of the optical edge was also determined on a cadaveric normal human heart, and it was confirmed that the calculation with the above formula would not be affected by the displacement of the optical edge due to the change of focal distance.
    3. Measures representing twelve principal points on the cardiac silhouette and the transverse diameter of the chest, as obtained by the orthoscopic technique in ventro-dorsal and right lateral positions were compared with those calculated from the data on the fluoroscopic image by means of the above formula. The result confirmed the validity of the author's procedure, even in the case of large hearts of athletes.
    4. The author considered various condition, such as the position of the chest, the phase and depth of respiration, the phase of the cardiac cycle, the half shadoW, and the geometric sharpness of the fluorecent screen. The effect of the displacement of the chest to the right or the left on the breadth of the aorta was very distinct.
    5. The data obtained by the present method of conversion from the short distance roentgenogram can be compared with those of teleroentgenography with discrepancies not larger than 2%.
    6. Various convenient procedures on the above principle were also tried and suggested.

    1.食物の好き嫌い,偏食等の概念を吟味し,嫌食児という概念を規定した.多数例の調査によつて嫌食児を概観し,次の諸点を確認した.
    2.嫌食の対象については:(a)年長者の食べないもの.年長者が不平をいうものに多い.(b)植物性食品,殊に根菜類,就中ニンジンが多い.(c)調理法によつては同じ材料でも食べられるという者が比較的多い.(d)鶏卵,獣肉は圧倒的に好まれ,野菜はほとんどの者に嫌われている.特にネギ,ミツバ,セリの様に匂いのあるもの,苦味,辛味のあるものは,それが嫌いの理由となつている.
    3.当入の個性的要因について注意をひくのは1(a)嫌食学童中の75%は自らの努力にも拘らす,それを食べ得ない者である.(b)各食品種別による嫌食の男女差はほとんど認められない.(c)体質異常と娠食との関係は認め難いようである.(d)嫌食開始期については,初期からの嫌食例が2λ5%,弟妹出生に基くfrustrationに由来すると思われる者が56.7%あつた.
    4.環境的条件については:(a)若い母親の男児よりも,年取つアこ母親の男児の方に植物性食品を嫌う者が多いようである.(b)嫌食児は無職家庭に多く,労働者の家庭に少い.(c)食物教育は一入子の男児の牛数以上に欠如している.(d)娠食幼児に対する母親の矯正努力は一般に強力,適切でなもの.(e)刺身,果物を食べない小児は多く給料生活者の家庭に分布している.
    5.幼児と女子大学生とを対照し,人参を例にとり,成長に作う嫌食の推移を検した結果によると,人参を娠う者は幼児の64.9%であるが,青年期には4.1%に減る.刺激性食品は幼児期には嫌われるが,長すれば嫌う者より,もむしろ好む者の方が明かに多くなる.6.以上の観察に立脚して娠食の矯正のための対策の指針を列挙した.

    1. Village Miwa, Nagano Prefecture, where the Sekiguchis live, is a typical rural community in a highland district of Central Japan. A survey showed 20.5% of the whole couples in this village were of consanguineous marriage, including that between second cousins and of nearer relations.
    2. Further detailed survey involving 149 consanguineous couples and as many nonconsaguineous couples revealed various features of marriage customs concerning matrimonial selection.
    3. Selection is done by other persons in 60-70% of marriages on the male side, in more than 80% on the female side. In most of the cases the father or the parents are responsible for the selection.
    4. Comparison between consanguineous and non-consanguineous marriages as to various criteria considered in the matrimonial selection disclosed a most probable primary reason for the appalling frequency of the consanguineous marriage. It is the sentiment of unity, involving various units of community formation. This is actually sentiment lying on the bottom of morals and customs of the Japanese race. As characteristics of community structure in Japan, stratification by traditional social ranking and segmentation by personal familiarity or relationship are very conspicuous; and these are conditioned by sentiment of unity of the group as against the remaining part of the public.
    5. Much is not expected, therefore, from eugenic attempts in the form of mere intellectual dissuation toavoid consanguineous marriage, sofar as the custom in rural Japan is concerned.
