Clinical heart failure may be divided into two categories, i. e., disturbance in energy generation system and that in energy utilization system. For instance, Basedowian heart or beriberi heart belongs to the former, and congestive heart failure belongs to the latter. Author
made

series
of animal experiments, using various preparations affecting one or another of the above-mentioned systems, and pursued the correlation between function and metabolism of heart muscle employing ATP, HMP, ATPase, etc., as indices.

The Research Vessel/Cape St. Mary of the Fisheries Research Station, Hong Kong, has
made

series
of deep-water Agassiz trawls over the northern part of the South China Sea during the past years. As a result, an adequate collection of deepwater forms of the Brotulidae is now available for a review of the family in the area. The present paper is the first of a series of studies on this collection of brotulids. It involves the proposal of a new genus and species, which was tentatively identified by the author (CHAN, 1965) as a Barathronus species in a list of fishes associated with the occurance of an anacanthobatid skate.

In order to study how the difference of the area at the opening of a cod end affects on the resistance of the net, the author deduced a theoretical relation between R/(KSn) and x²/S for various pyramid type cod ends of which the area at the opening is changed when another resistance-factores are maintained constant (Eq. II-3). Where R denotes the total resistance of the cod end, K the resistance of the unit area of plane net fixed at right angle to the stream, S_n the total area of webbing, S the area at the opening and x the total length of the cod end.
Further, the author
made

series
of experiments on the model net of cod ends of which the area of the opening are 162cm²., 200, 224, 392 and 578, and compared experimental results with the results calculated by the Eq. II-3 and is plotted in Fig. 11, from which the author make sure of the following fact:
In regard to the cod ends which are very short as compared with the area at the opening (e.i. 0<x²/S<5), the resistance is affected by the change of the area at the opening (e.i. the resistance decrease to about half of the resistance of the cod end which is zero in x²/S), but in regard to the cod ends which are moderately slender as are used in fractical trawl net (e.i. 5<x²/S<30), the resistance is hardly affected by the change of the area at the opening.

In recent years high strength steels for low temperature use have been developed for application and increased importance has come to be attached to their welding In this report special attention was paid to evaluation of weld cracking sensitivities of the 9 percent nickel steel electrodes (Table 1). Four kinds of electrode (10N, 20N, 40N, 70N, see Table 2) with different nickel contents were selected for the test. The RRC-test¹⁾ was adopted for the cracking test. Two series of experiment were
made
;
series
I was to evaluate weld cracking sensitivity except for crater cracks and series II was to evaluate crater cracking sensitivity.
In the test series I, weld cracks as shown in Fig. 4 were observed on the bead surface and inner weld metal of the ION, 20N and 70N electrodes under high restraint. The critical gauge length of restraint (l_cr) over which no weld cracks were observed was about 200 mm. Weld cracks as shown in Fig.4 were not observed in the 40N electrode weld metal even for 100 mm gauge length of restraint. Therefore l_cr for the 40N electrode will be less than 100 mm. Crack formation temperature was estimated higher than about 900°C and may be near the solidus temperature of weld metal.
In the test series II, crater cracks were observed even in specimens almost free from restraint or with l>3000 mm. Crater cracking seems to be almost independent of the magnitude of restraint It will be important, therefore, to take away the crater for avoiding weld cracking of the 9% Ni steel weldments.

Using a steel material for forging, development of new discs for the next Shinkansen had been started. However, a fracture in a forged disc occurred in a durability test. Subsequently, from the viewpoint of higher fracture toughness, material improvement to an extent sufficient to withstand such a fracture due to tensile residual stress accumulation became the goal of further development. Among the candidate materials, modified AISI 4330 was selected and evaluated in laboratory and field tests. Following the subsequent durability test in the field, modification for bolt sticking and forging formability was conducted. This new brake disc, which proved to be satisfactory for Shinkansen vehicles, is capable of running at high speeds of more than 270km/h and therefore suitable for current vehicles such as the Nozomi and Tsubasa.

Sets of time domain reflectometry waveforms analyzed with appropriate chemometric methods, instead of typical single waveform analysis, enable one to detect and quantify differences between waveforms, even if they appear at the level of several orders of magnitude below the scale of the measurements. Typical applications of such an approach to samples of healthy and damaged grain showed that differences contributing five orders of magnitude below the scale are still detectable. Under more rigorous experimental conditions, the level of detectable differences can be expected to be even lower.

The author
made

series
of study on the mode of living of students in certain evening senior high school in Tokyo. The results obtained are reported in the following two chapters.
Chapter I.
In this chapter the author made an investigation on the daily life of evening school students in order to make the status quo of their life clear, and understand the nature of problems resulting from the status. The author also tried to find solutions of the problems so as to improve the system of education in evening school.
1) The daily life of evening school student presents a marked difference from that of day school students. The difference may mainly be resulted from the fact that the most of evening school students engage in their day-time jobs.
Time available for rest, recreation, reading and other extra-curricular activities must be quite limited in case of evening school students compared to that of day school ones.
2) It was estimated that only 54% of freshmen were able to finish the four-year full course, namely the rest of freshmen left school on a half way of the course. This may be said as a special phenomenon in evening school and this matter may cast one of the serious social problems.
3) Not a few students are absent or late in class because of their day-time jobs. As many as 47% of the students are listed on the record of disease and injury.
4) About 90% of the students have jobs in the daytime. Twenty-one per cent are engaged in heavy work according to their subjective description. This fact must seriously be considered for the sake of successful evening school education.
5) The monthly income is 5, 000 yen on average and about 40% of the amount supports their tuition and other school-expenses.
6) An examination on the degree of their fatigue clearly indicates that the type of fatigue is not physical but rather volitional or emotional one.
7) An examination of menstruation of evening school girl-students indicates that amenorrhea is prevalent compared to day-school girl-students.
8) As regards their family life, the number of inmates per family is 6.8 persons and this means a greater rate than in case of day-school students.
9) In regard to their sleeping-hours, many of them go to bed later than 11 o'clock in the evening and their sleep is naturally unadequate compared to that of day-school students.

Induction of a delayed type hypersensitivity to carrageenin in mice was investigated with successful results. Male ddY/s mice were immunized with 1 mg of carrageenin in 100μl of Freund's complete adjuvant-saline (1 : 1) emulsion and challenged 10d after the immunization on their footpads with either 10 or 40μg of the antigen in 2.5μl of Freund's incomplete adjuvant-saline (1 : 1) emulsion. The mice exhibited a strong allergic footpad reaction at 24-48h after the challenge injection. The footpad reaction was successfully transferred with spleen cells. Non-steroidal antiinflammatory drug, indomethacin, and steroidal antiinflammatory drug, dexamethasone, suppressed the delayed type hypersensitivity reaction.

マオウ属植物の花粉は減数分裂ののち,小胞子,胚的細胞,造精器細胞,生殖細胞,中心細胞による5回の細胞分裂を経て完成する.分裂はすべて不均等分裂であり,前4個の細胞では,楕円形をなす細胞の長軸の一端へ紡錘体が偏在することがその一因となる,さらに,分裂の不均等性をより増幅するフラグモプラスト(隔膜形成体)の特異な発達様式が明らかとなり,その特徴は,造精器細胞分裂において顕著であった.造精器細胞分裂終期の早期,フラグモプラストは,微小管が集合した2群のリング状構造として2娘核間に出現する.2リングは同じ径をもち,各微小管は分裂軸に平行に配向し,遠心的に成長するという通常の様式を示す.しかし,終期の中頃,リングを構成する各微小管は分裂軸に対し垂直へと配向を変え,それに伴い2群のリングの径に差が生じ,互いに同心円状へと配列を変える.さらに発達方向を分裂軸に対して平行に,2娘核のうちの生殖細胞核を包み囲む方向へと転じる.終期の晩期には,微小管のリングは再び早期のそれと同様の配列にもどりつつその径を減じ,細胞長軸の一端の細胞膜に達し,不均等分裂を完了する.また,中心細胞の分裂では,フラグモプラストは2娘核間で通常の発達を開始するが,やがて発達を停止し,細胞板を形成することなく退化・消失する.その結果,2娘核を含む1個の精細胞が形成されるが,2娘核には大きさの差が生じる.

腸管感染症の感染および感染防禦機構を研究する一環として, in vitroやinvivoの感染モデル試験により, 赤痢菌等の病原性について検討してきた.本報では, 動物腸管結紮ループ起炎性試験 (Detest) を
家兎・モルモット・マウスの3種で行い, 炎症発現の有無を観察し, 本試験の有用性について調べた.家兎・モルモットの腸管を用いた結紮ループ試験では, 侵襲性病原菌と毒素性病原菌ともに炎症を呈し陽性であった.マウス腸管では元来毒素性病原菌の検査法として用いられてきたが, 侵襲性病原菌の場合にも反応時間を延長すると約1/3に陽性が観察された.
マウス腸管を滅菌PBS-で洗浄した場合や手術3日前に, マクロファージ機能抑制剤であるcarageenan (100mg/kg) を投与したマウスでは, 陽性率は約1/3であり, 無処理マウスの結果とほぼ同様であった.これに対して, 腸管内細菌叢抑制のため3日間lmg/mlのChlomamphenicolを飲水投与または3日前に好中球機能抑制剤であるcyclophosphamide (100mg/kg) を投与されたマウス群では陽性率は約2/3に上昇した.
その結果, マウス腸管内細菌叢の除去または好中球機能低下せしめたマウスにおいて, 腸管結紮ループ起炎性試験が陽性になりやすいことを明らかにした.これらの処理により, マウス腸管結紮ループ試験は, 毒素原性菌とともに侵襲性病原菌の検出方法としても利用できることを示した.

エアロゾルと雲の放射がアジアモンスーンに及ぼす影響を気象庁全球モデルを用いて調べた。エアロゾルによる直接及び間接の放射効果をパラメータ化した。また、陸上での雲量が標準モデルより増加するようにパラメタリゼーションを変更した。これは陸上では地表面の非均一性などが雲の形成を容易にし雲粒サイズが小さいため雲の滞留時間を長くしていると考えたためである。
アジアモンスーンの予報はエアロゾル及び陸上での雲の増加のパラメータ化に大変敏感であった。標準モデルは陸上で太陽放射吸収量を過大評価する。雲の診断パラメータを海陸で区別しエアロゾルを考慮することにより、標準モデルに現われた太陽放射吸収量の海陸コントラストに関する系統的な誤差を減少させることができる。ユーラシア大陸では太陽放射が減少し大気陸面相互作用を通じて下層気温が低下する。その結果、東南アジアのモンスーン循環を弱め、東アジアの典型的な前線帯、メイユ、チャンマ、梅雨などの北上を遅らせる。
陸上における雲の増加の影響とエアロゾルの影響はよく似ている。太陽放射吸収量の系統的誤差の減少は両パラメタリゼーションの妥当性を示唆しているが、その相対的な大きさはまだ評価できない。エアロゾルの分布や光学特性および雲の形成について、エアロゾルと雲の相互作用も含めて、とくに海陸の相違に配慮した研究を進める必要がある。
