Abstract A pot experiment was conducted to study the relative performance of IR 6,KS 282 and IR 10198-66-2 rice varieties cultivated under salt-affected conditions at EC of 6.0,9.0 12.0 dS m(-1) in a sandy clay loam soil havig ECe of 1.6 dS m(-1) treated as control. Six seedlings of 39-day old transplaned to each pot having 12 kg soil. The fertilizer as nitrophos and potassium sulphate at the rate of 57.0, 25.0 and 50.0 mg N,P and K kg(-1) soil respectively was applied at the time of transplanting while zinc sulphate at the rate of 5 mg Zn kg(-1) soil and 43.0 mg N kg(-1) of soil as additional dose were applied 19 and 30 days after transplanting respectively. Normal plant protection measures like number of tillers, panicles, paddy grains, filled and unifilled grains, yield per plant and sterility were recorded and shoot and straw samples were analysed for sodium, potassium, calcium and chloride contents. It was observed that growth and yield of all the varieties were reduced significantly with increasing soil salinity. Na/K and Na/Ca rations in shoot and straw increased significantly with increasing soil salinity. It was also observed that higher values of Na/K and Na/Ca rations in shoots affected growth parameters while higher values of these rations in straw affected yield components and grain yield. However, IR 6 having relatively lower values of Na/K and Na/Ca rations proved to be the most salt-tolerant rice among the three varieties studied.

Abstract 気管支喘息に対する温泉療法の効果が,これまでどのような評価方法により判定されてきているのかについて,若干の文献的考察を加えた。効果に対する評価方法は,臨床的評価と作用機序と関連した評価方法とに分けて考えることができる。臨床的評価方法としては,自,他覚症状の改善,同時に使用された薬剤の減量の程度,あるいは,肺機能検査の各パラメーターの変動の比較などの方法により行なわれている。一方作用機序と関連した評価では,喘息の発症機序とある程度関連した温泉療法の作用を中心に検討が加えられている。例えば,喘息の発症機序として重要な位置を占める免疫アレルギー反応,自立神経系,内分泌系などと関連した指標を用いて,その変動を観察することによって,効果を明らかにしようとする試みがなされている。これらの検討は極めて意義深いが,なお今後IgE系反応や気道の過敏性との関連 などについての追求が必要であるように考えられる。

Abstract Theoretical drainage equations are intensively tested in many parts of humid and arid regions and are commonly used in drainage design. However, this is still a great concern in Japan as the drainage design is exclusively based on local experiences and empirical basis. There is a need therefore to evaluate the theoretical drainage equations under Japanese field conditions to recommend equations for design of subsurface drainage systems. This was the main motivation for this study. While drainage requirements of different crops are difficult to define quantiatively, adequate drainage can probably be provided by designing for a given water table recession rate. The method used was to measure the rate of water table recession and drain outflow after cessation of a considerable amount of rainfall. Based on these measurements, soil parameters were determined and nine drainage equations were tested in simulating water table recession against actual field data of two drained experimental sites, located in Soja city west of Okayama prefecture, Japan, having drain spacing of 10 and 8.5 m for a period of two years. An experimental drainage equation was also derived and theoretical equations were recommended for design of subsurface drainage systems.

Abstract 気管支喘息に対する温泉療法,特に温泉所在地(保養地)の環境,すなわち気候条件の喘息に対する影響について,文献的考察を加えた。気候療法としては,主として山岳気候,海洋性気候,洞窟気候などが,喘息の治療に応用されている。これらの気候は,いずれも喘息に対して有効的に作用することが示されているが,それぞれの特徴を持っている。例えば,山岳気候は酸素分圧が低いこと,水蒸気圧が低いことなどが特徴であり,そのため生体がそれに適合するためにはある程度の時間が必要となる。一方海洋性気候は,海塩粒子を含んでおり,海水エロゾル中のカルシウムやマグネシウムなどが良い影響を与えると考えられている。また洞窟気候は,水分含量が均一であり,電解質,特に陰イオンが多く,これが粘膜活性や浄化活性を亢進させると言われている。またいずれの気候療法も,副腎皮質機能の活性化をもたらすと考えられている。

Abstract Major failure of structures usually occurs during flood flows due to scourin, sinking and sliding. These types of failure are considered to be in close relation to the dynamic behavior of bed material around the structures. Failure of bridges due to the phenomenon of scouring around piers is a common, natural problem of river hydraulics. Experiments were carried out to investigate the characteristics of pore water pressure and effective stresses in the bed material around a circular bridge pier under abrupt change of water pressure. A laboratory model was used to clarify the effect of the variation of water pressure to determine the mechanism of the collapse of circular bridge pier during flood or storm waves. The experimental results showed that the bed material under suddeen change in drop of water pressure near the pier was weakenend by an increase in excess pore pressure, followed by a considerable quick removal of bed material.

Abstract For reducing or bridging gap between small scale laboratory investigations and large scale field investigations, a simple and portable model which is based on real situation and has a compatibility to laboratory core sampling, the pressure infiltrometer technique is introduced for determination of field-saturated hydraulic conductivity. The field -saturated hydraulic conductivity, K(FS), is obtained from measurements of steady flow rates applying constant head as well as falling head principle. The device is also used for field core sampling on which laboratory constant head as well as falling head tests is carried out. The field device is validated through comparison to laboratory core sample experiment and other existing methods. This paper describes first time a versatile field device representing good performance for in situ determination of hydraulic parameters in a short time.

Abstract An analytic approach that provides explicit estimates of risk on cataract and epilation data is evaluated by reasonableness of conceivable relative risk models regarding a simple, odds, logistic or Gompertz regression method, assuming a binomial distribution. In these analyses, we apply relative risk models with two thresholds between epilators and nonepilators from a highly characteristic lesion of which radiation cataract does not occur around 2 gray for a single acute exposure. The risk models are fitted to the data assuming 10 as a constant relative biological effectiveness of neutron. The likelihood of observing the entire data set in these models fitted is evaluated by an individual binary-response array. Estimation of a threshold with or without severe epilation and the 100(1-α )% confidence limits are derived from the maximum likelihood approach. The relative risk model with two thresholds can be expressed as a formula with structure of Backgroun × RR, where RR includes threshold models with or without epilation. The radiosensitivity of ionizing radiation to cataracts has been examined for the relationship between epilators and nonepilators.

Abstract One of major problems in spatial analysis is to estimate the value z(s(0)) at an unknown location s(0) using the information about observations z(s(α)), α = 1,…,n. In this article, we will perform a numerical study about some methods for this problem. That is, we examine both the tranditional statistical method which does not take into account spatial correlation and the spatial statistical method which takes into account spatial correlation by applying them to a set of non-stationary spatial data. We compare the predictive powers of these methods. More precisely, we choose Universal Kriging(UK) and Median-Polish Kriging(MPK) as spatial statistical methods, and locally weighted regression or LOESS as a traditional method. As the major criterion for comparison, we use the so-called PRESS statistic, and also draw the prediction surface plot and the prediction standard error surface plot as minor criteria. A real numerical example of non-stantionary spatial data is analyzed for the comparison among the above three methods.

Abstract 選択的H(1)受容体拮抗薬であるTerfenadineの抗アレルギー作用,特にIgE系反応によるヒスタミン,およびCa ionophore A23187による好中球からのleukotrienes遊離に対する抑制作用を,ヒト末梢血白血球を用いて検討した。1.Terfenadineは,抗ヒトIgE刺激による健康人好塩基球および特異抗原刺激による気管支喘息患者好塩基球からのヒスタミン遊離に対して,全血法でのin vitro添加実験では有意の抑制作用を示さなかった。 2.洗浄白血球法によるin vitro添加実験では,Terfenadineは特異抗原および抗ヒトIgE刺激時の気管支喘息患者好塩基球からのヒスタミン,Ca ionophore A23187刺激時のleukotriene B(4)遊離に対して有意の抑制効果を示した。3.Terfenadineの内服によるin vivoの抑制実験では,IgE系反応による健康人および気管支喘息患者好塩基球からのヒスタミン遊離に対して有意の抑制効果は見られなかったが,特異抗原による皮膚反応に対しては明らかな抑制作用が観察された。以上より,Terfenadineは,組織肥満細胞および組織へと遊走してきた好塩基球に対してはある程度の抑制作用を有しているものと考えられた。

Abstract 臓器反射スペクトル法と内視鏡を併用して胃粘膜血流を測定し,当院温泉水飲用の消化機能に対する基礎的検討を胃粘膜血流を指標に行なった。温泉水の対照として空気と白湯を選び3群に分け検討した。その結果,温泉水は空気に比し胃粘膜血流を増加させる作用を有していることが示唆された。また温泉水は部分的ではあるが白湯にくらべても胃粘膜血流を増加させる作用があることが示唆された。よって飲泉療法の消化器疾患に対する臨床的有用性が胃粘膜血流の面からもうかがわれた。

Abstract 我々は,既設の消化管診断用X線TV装置(東芝BV型)を使用した立体拡大撮影システムを検討した。1.消化管診断用X線TV装置の透視天板の高さが一定であるため,従来のフィルムチェンジャー(AOT)では不可能であったが,上下動可能なフィルムチェンジャー(福放FC-10L特)を改良試作したことで最大2倍までの立体拡大撮影が可能となった。2.透視観察から撮影へ,コンタクト撮影から拡大連続撮影,立体撮影から立体拡大連続撮影へと併用して行うことが非常に簡単にできて被検者の負担軽減と多目的使用が可能となった。3.観察条件と立体感については,拡大率を変化させて,その立体感について検討した結果は、観察距離については,各拡大率における立体視しやすい距離は存在し,拡大率が2倍の場合には,観察距離を大きくするほど立体感も増加し,立体視し易い傾向が示された。

Abstract According ot previous studies, we may expect that slow oscillations can occur in dynamics of a parameterized family of systems in which a biochemical oscillator is coupled to a stationary systems. We introduce some numerical results that confirm our expectation. The results suggest that it is possible for slow oscillations to occur in dynamics of a system in which an active oscillatory unit is coupled to a passive medium, and that it is possible for circadian oscillations to arise from fast glycolytic oscillations in such a coupled system.
