生体のタンパク質を構成するアミノ酸の立体配置はL体であることはよく知られているが, そうなった理由はまだはっきりしていない。ただ, L体のアミノ酸から成るタンパク質系は物質の進化で形成されたと考えられている。ここでは, アミノ酸, ペプチド, タンパク質の片手構造について説明し, L体のタンパク質系の生成した過程を化学進化の点から概説する。

Molecular-level understanding of ice crystal surfaces holds the key to unlocking the secrets of various fields. To observe ice crystal surfaces at the molecular level, we developed an advanced optical microscope, and succeeded in visualizing individual elementary steps of 0.37nm in height on ice basal faces. Utilizing this microscope, we also attempted to visualize the surface melting processes of ice crystals. We found the presence of two types of surface liquid phases (quasi-liquid layer phases) that exhibit different morphologies and dynamics on ice basal faces.

For the rice powder breads added to pectin or guargum were made, the particulate distributions of rice powders, composition of rice powder breads, sensory evaluation and textures of the rice powder breads were examined. (1)The particulate distribution of rice powders was 10-200 μm. (2)The productive methods of rice powder breads were put 300 g at water and 300 g at rice powders in a pan cakes. The methods were put 4 g at salt, 9 g at guargum, 18 g at sucrose, 30 g at trehalose, 9 g at skin milk, 30 g at margarine and 3 g at dry yeast in pan case. (3)The rice powder bread at this productive method was good optimum ratio of material composition. (4)The hardness stress of texture of rice powder breads decreased that the ratios of material composition of sugar and trehalose increased. (5)The cohesiveness stress almost did not change that the ratio powder compositions of sugar and trehalose increased.

An experimental study is made to know the effect of working axial compression on the reductionof load carrying capacity of interior beam-to-column connection in steel reinforced concrete frames.Experimental variable is the ratio of applied axial compression to the ultimate compressive strength.Main discussion is concentrated on the shear strength, failure mechanism, strain history of webpanel and flange portion and hysteretic characteristics involved in the large deformation range undermonotonic and repeated loading. It is concluded that the load carrying capacity of beam-to-columnconnection that is supposed to fail in shear is hardly affected by magnitude of axial compressionon column

The middle part of Ishikari Plane (or Sapporo Lowland) is situated in Lat. 40&deg;00'-43&deg;25' N. and Long. 141&deg;12'-141&deg;53' E. In this plane, there are the Neogene Tertiary formations which are overlaid with the Quaternary formations of about 100m in thick.<br> 1. The Neogene Tertiary formations cropping out in the surrounding mountains district are overlaid with unconformity on the Paleogene coal-bearing formations, the Cretaceous System, and so-called &ldquo;Pale-ozoic&rdquo; formations.<br> 2. In the Neogene formations of this plane, according to the stage of depositon, there are marked variations in the density of deposits and distribution of fossils. There is no remarkable unconformity, however, in the Neogene Tertiary formations and each formation distributes in all the area, but the thickness of formations is changeable and most thick between the Nopporo Hill and Umaoi Hill.<br> 3. On the land surface or near the surface of this plane, igneous rocks have not been discovered and will not be discovered in future.<br> 4. The Neogene formations have folded structures with axes of approximately north-south direction and they are thought to have been resulted from upheavals of the Hokkaido Backbone Mountain Lands or Hidaka Mts.<br> 5. While the synclinal parts of folding structures are large and broad, their anticlinal parts make steep dip wings and narrow forms. Anticlinal parts are assymmetrical forms and thir axial planes are inclined to west ; that is, they show the nature of &ldquo;west steep-east slow.&rdquo;<br> 6. The axial planes of anticlinal structures in the eastern area are extreamly dipping. The angle of dip is smaller in the western area and it takes almost the similar shape of symmetrical anticline structure in the Ishikari coastal region. On the contrary, in the northern mountainous districts of the plane, the axial planes are inclined to east and the anticlinal structures show &ldquo;east steep-west slow&rdquo; character. In these mountain regions where crops out of basement complex as Kobato Paleozoic sediments, folding waves are pushed back for eastern side against the lateral forces caused by the upheaval of backbone mountains. Consequently, these folding waves advanced towards the Neogene basin axis <sup>(10)</sup> (Tomakomai-Takikawa Line) from both sides of east and west mountains (Fig. 12).<br> 7. In the plane, each anticline structure is continuous without faults or echelon arrangement, and there are some upheavals making dome-like structures. On the contaary, however, there are some sinking areas making structural depressions along the synclinal axes. These depressons are distributed at regular intervals, and the distribution of the recent rivers are related to these depressions.<br> 8. The meander zones of rivers distribute centering around Masarikappu near Ishikari Coast elliptically and radially. This distribution shows that the southern mountains slow upheave contrary to the northern mountains (Kobato Mts.).<br> 9. Accordingly, it is revealed that each basement complex (pre-Neogene) of mountains in the northern, southern, and eastern parts of the plane belongs to different geologic structural unit. It is thought that these three blocks made different block movements and these geological movements produced effects on the Neogene Tertiary structure in this plane.<br> The above are interpreted as follow.<br> (1) Southern mountains to which the Ezo-Fuji Volcanics belong are a range from the Central Mountains in North-East Japan where is the Nasu Volcanic Zone.<br> (2) The eastern mountain range is not connected with the land of North-East Japan.<br> (3) The Abukuma and Kitagami ranges in North-East Japan belong to tne same mountain series with Kobato range in the north of Sapporo Lowland.<br> (4) There are geological structure lines between Sapporo Lowland and mountainous districts.

誘発によらない自然発症時の過換気症候群 (HVS) の病態を解析する目的で, 過去11年間に当院を受診したHVS患者508名の病歴を検討し, さらに, 質問票を郵送して緩解期の症状と予後の調査を行った. 急性HVSは10歳代女性に多かったが, 5~85歳と幅広く分布していた. 主症状は呼吸困難やしびれが多く, 誘発試験の症状 (胸痛, 動悸等) と異なっていた. 誘因の多くは不安や悩み, 発熱, 嘔気・嘔吐で, 約20%の患者が不安神経症を併発していた. 約半数の症例は, 疾患の説明のみで症状の軽快を得ていた. 以上の結果は血液ガスを確認した群と臨床所見のみで診断した群で大きな差はなかった. 慢性HVSの頻度は約2%で, 中年女性に多かった. 急性・慢性のHVSの約半数で発作を反復しており, 約10%で反復期間は3年以上であった. 長期間急性発作を反復する症例では, 緩解期に空気飢餓感やため息を認めた. 以上より, HVSの診断における臨床所見の重要性を強調したい.
