Title Alternative Measurement of Serum Lipid Peroxides used Thiobarbituric Acid Method: Colorimetric and Fluorometric Assays and Effect of Ferrous Ion
FullText URL 002_051_061.pdf
Author Yamamoto, Goki|
Abstract Serum lipid peroxides were measured by a thiobarbituric acid (TBA) method. TBA color reactions carried out under the conditions with acetic acid (TBA-AA) or hydrochloric acid (TBA-HCl) systems, and then TBA value was detected by colorimetric ([OD]) and fluorometric ([FR]) measurements. Effects of ferrous ion, ferric ion and EDTA on the both systems were examined. Equal TBA value dependent upon concentrations of MDA (tetraethoxypropane) were obtained on both systems detected by [OD], but the relative fluorescence of TBA-AA system was higher than that of TBA-HCl system. Fluorometric determination was suitable for low TBA value, and colorimetric one was for high TBA value. Good correlation between TBA[OD] values and TBA[FR] values of serum from patients was estimated, but it was suggested that effects of serum substance were differ on the both systems. Effects of iron on TBA-AA and TBA-HCl systems were different significantly, particularly high Fe-TBA values obtained from TBA-AA system in the presence of ferrous ion. The fact suggests that serum lipid peroxidation is induced by ferrous ion during a heating of TBA color reaction. Same effect of ferric ion in TBA-AA system was observed. The increment of TBA values by ferrous and ferric ions was inhibited by a addition of EDTA. It was considered that the difference effect of iron on the both systems was due to pH and acetic acid concentration. The relationship of TBA values and Fe-TBA values of serum from patients was no correlated, and the various inhibition ratios of EDTA for the TBA value was calculated. It is suggested that Fe-TBA value is possible to detemine the qualitative difference of serum lipid peroxides.

Title Alternative Enzyme Immunoassay for Rabbit C-reactive Protein
FullText URL 002_023_028.pdf
Author Mori, Shuji|
Abstract Sensitive enzyme Immunoassay method specific for rabbit C-reactive protein was established. This was based upon specific Ca(2+)-dependent binding profile of C-reactive protein for some compounds containing phosphorylcholine moiety intramolecularly. By this method, more than 0.001μg of rabbit C-reactive protein was detectable. Specific binding of C-reactive protein for p-aminophenylphosphorylcholine immobilized on solid phase was inhibited by either addition of EDTA or phophorylcholine analogues, effectively. It may be useful to study possible roles of C-reactive protein in inflammatory regions.

Abstract 耐熱性ホスファターゼを含んだBacillus stearothermophilus 粗酵素試料を、リソースIsoによる疎水性クロマトグラフィにかけ分離を行った。1.5M→0M 硫酸アンモニウムの直線逆濃度勾配によって溶出を行ったところ、ホスファターゼは不活性な形で溶出され、これは硫酸アンモニウムによる濃度依存的阻害に起因することが判明した。ホスタファーゼの反応混合液に種々の濃度の硫酸アンモニウムを添加したところ、0.15Mの硫酸アンモニウム存在下で約80%の阻害が認められた。加えて、この阻害作用は単に硫酸アンモニウムの添加によってpHが酸性側に傾くことによるものではないことも明らかとなった。

Abstract 胸部専用の新しい増感紙/フィルムシステムについて物理的画質特性を測定し、従来のシステムと比較を行った。測定した新システムは、日本コダックのインサイトシステムからHC/IT-1、富士メディカルシステムのADシステムからHG-M/UR-1、コニカのEXシステムからXG-S/ES-C である。従来のシステムとして富士メディカルシステムのHR-4/Super HR-S を使用した。その結果、新システムは22~73%感度は高く、特性曲線においては低濃度部を持ち上げ、最大コントラストは高濃度側にシフトしていた。空間周波数2cycles/mmで相対鮮鋭度を比較すると、新システムが10~30%程度の低下となっていた。ノイズは、濃度1.0で新システムが35~46%の減少となった。以上より、新システムは、縦隔部の濃度を上げ、粒状性の改善を重視した設計となっていることが分かった。

Abstract マンモグラフィ専用装置を使用して,距離法で低エネルギー領域のX線におけるマンモグラフィ用増感紙/フィルムシステムの特性曲線を得るためには,空気滅弱の影響を考慮する必要がある。その影響について,実効エネルギーから空気減弱分を補正,照射線量測定による補正,Bednarek法を応用した新距離法の3種類の方法を使って検討した。さらに,一般撮影装置でも,マンモ用システムに対して距離法で特性曲線を作成し,エネルギ ーの変化による影響についても検討した。その結果,3方法の特性曲線およびグラディエント曲線は,新距離法が高濃度域でわずかにずれるもののほぼ一致した。新距離法に対する平均階調度,最大階調度の最大誤差は,2.7%,0.2%であり,一般撮影用装置の距離法と3方法との間では,一般撮影用装置の距離法に対して最大誤差は2.7%,1.5%であった。以上のことから,エネルギーの変化による特性曲線への影響はほとんどなく,低エネルギー領域での特性曲線は空気特配の補正を行うことのみで得られると考えられる。

Abstract 自動現像機の濃度管理に用いられるフィルムの保存については,種々の報告がなされており,最良の方法が確立されているとは言い難い。さらに,レギュラフィルムとオルソフィルムの保存方法の違いによる濃度管理への影響,あるいはこれらの比較については,これまでほとんど報告されていない。本論文では,われわれは,レギュラフィルム,フジnew-RXとオルソフィルム,コニカSR-G,SR-VおよびSR-Hを用い,開封後,室温,冷蔵,冷凍の3種類の保存方法を採用した。われわれは,35週間3種類の保存方法で4種類 のフィルムのgross fog,speed indexとaverage gradientへの影響を調査した。その結果レギュラフィルムは,3種類の保存方法による差が認められなかった。オルソフィルムでは,冷蔵・冷凍保存に大きな特性変動が認められた。その原因として,オルソフィルムは増感色素が結露に対して敏感に影響を受けたと考えられた。

Abstract This paper describes the prediction of seepage in the impervious zones of six embankment dams by seepage analysis. In addition, by making use of the available monitored pore water pressure data of the first filling of reservoir, back analysis was carried out to estimate the best fit seepage parameters. The estimated parameters were used for further prediction of pore water pressures in subsequent monitored durations with reasonable accuracy. The accuracy of prediction was evaluated quantitatively by the prediction difference and error index. The results show that the error indices in the upstream sides of the impervious zones are smaller than those in the downstream sides.

Abstract Monodispersed porous polymer microspheres having diameter of ca. 50 μm were successfully prepared by suspension polymerization of styrene, polyoxyethylene methacrylate and ethylenegycol dimethacrylate. Monodispersed O/W emulsion was firstly made by SPG membrane emulsification technique, following droplets-swelling method of monodispersed seed emulsion by the addition of secondary emulsion. The effect of solvent used in suspension polymerization on porous structure of prepared polymer microspheres was investigated in this paper by identification with scanning electron microscopy, porosimeter and the performance in gel permeation chromatography. It was found that benzene, 1-butanol and butyl acetate worked as poor solvent for polymer prepared in this study and that polymer microspheres prepared with these solvents had larger pores. Gel permeation chromatography measurements indicates that polystyrene having molecular weight smaller than 50,000-100,000 can be clearly separated by using gel columns packed with polymer microspheres prepared with poor solvents.

Abstract This research was conducted to clarify the membrane formation mechanism of crosslinked polyurea microcapsules by phase separation method, specially the role of polymeric surfactant of poly(ethylene-alt-maleic anhydride),(poly(E-MA))at the interface of O/W emulsion. Because of its toxicity, alternative chemicals should be chosen. This understanding may make possible to find the alternative chemicals. It was found that poly(E-MA)was necessary for the formation of crosslinked polyurea membrane. The addition of sodium dodecyl sulfate (SDS) prohibited the membrane formation reaction at the interface, even in the care of poly(E-MA) concentration enough for polymeric microcapsule formation. From the results in this study, poly(E-MA) as polymeric surfactant was found to be adsorbed on the interface of O/W emulsion and provide the reaction site for the membrane formation of polymeric microcapsules.

Abstract Inclusion of aggregates leads to a reduction in drying shrinkage of cement paste. This is due to the elastic deformation of the aggregates that partly restrains the shrinkage deformation of cement paste. Hence, concrete with higher aggregate content exhibits smaller shrinkage. In addition, concrete with aggregates of higher modulus of elasticity or of rougher surfaces is more resistant to shrinkage process. In this paper the effects of the type of coarse aggregate on the shrinkage of normal and high-strength concretes are investigated. Two different types of crushed stone were used as coarse aggregates to produce the concrete mixtures used in this study. For each coarse aggregate type, two normal-strength concrete (NSC) mixtures and two high-strength concrete (HSC) mixtures were prepared. The 28-day compressive strength values of NSC mixtures were about 35 and 50 MPa, while those of HSC mixtures were 70 and 100 MPa, respectively. All shrinkage specimens were cured in water for 14 days after casting, then exposed to drying under the conditions of constant temperature (20℃) and relative humidity (60%). It has been shown that the type of the coarse aggregate influences shrinkage behaviour of both normal and high-strength concretes.

Abstract In many epidemiological and medical studies, a number of cancer motralities in catagorical classification may be considered as having Poisson distribution with person-years at risk depending upon time. The cancer mortalities have been evaluated by additive or multiplicative models with regard to background and excess risks based on several covariances such as sex, age at the time of bombings, time at exposure, or ionizing radiation, cigarette smoking habits, duration of smoking habits, etc. An interest herein to examine an additive, synergistic,or antagonistic relationship between radiation exposures and cigarette smoking habits for cancer mortalities. The results revealed a highly significant antagonistic influence for cancer mortalities from all nonhematologic findings, lung and respiratory system with negative interaction between radiation exposures and cigarette smoking amounts.

Abstract In our study, we have investigated the influence of the intermediate host population density on the prevalence of Echinococcus multilocularis in the definitive host using a mathematical model of transmission. For the vole population (intermediate host) in Hokkaido, a model of population dynamics has been constructed in this paper which follows the seasonal and annual fluctuations. In the northeastern area, the vole density appears to fluctuate periodically with a 4 year cycle. The prevalence of Echinococcus multilocularis in the fox population (definitive host) can be affected by the density of vole through the fox ingesting infectious voles. Therefore we have prepared a food habit function of foxes and the logistic distribution has been proposed. The simulations which have been carried out using the mathematical model for transmission of Echinococcus multilocularis together with the vole dynamics have indicated that the prevalence in foxes is correlated and synchronized with the population dynamics of vole. In addition they have also made us recognize that it is necessary to introduce a suitable food habit function into the transmission model.

Abstract Fluorine-containing poly(ether ketone)s was synthesized by the nucleophilic aromatic substitution reaction of 2,2-bis(4-hydroxyphenyl)-1,1,1,3,3,3-hexafluoropropane and 4,4'-bis(2,3,4,5,6-pentafluorobenzoyl) diphenyl ether in super-critical CO(2). Polymerizations were carried out at 80℃ for 6 hours under 5000 psi of CO(2) pressure, which was super-critical phase. Polymerization concentration was 0.5 g of polymer in 10 - 12 mL of CO(2). The polymer was not obtained in CO(2) due to the insolubility of both the potassium bisphenoxide and the polymer into CO(2). However, the polymer was formed by an addition of DMAc and NMP in CO(2), even though molecular weight was not so high. Very small amount of co-solvents which were immiscible with CO(2) was effective, and it was 1/20 - 1/25 amount of the solvent used in the conventional poly(ether ketone) synthesis. The polymerization mechanism was also discussed.

Title Alternative Acceleration of Formation of Shish under Flow by Addition of Irregular Shaped Particles
FullText URL 012_157_160.pdf
Author Yamazaki, Shinichi| Wakabayashi, Kanji| Mizuma, Kenta| Kimura, Kunio|
Abstract We have shown that the shish was formed from the oriented melt composed of the elongated chains caused by dust particles within the melt via bundle typed nucleation under flow with low shear rate (γ=5s(-1)). This implies that dust particles effectively cause the elongation of chains within the melt. In this work, we observed the crystallization of polypropylene added with irregular shaped particles under shear flow by means of polarizing optical microscope. We prepared various shaped particles such as confetti-like, spherical and rock-like. We found that the size and asymmetric shape of additive particles play an important role for the acceleration of formation of shish.

Abstract The study addresses the influence of bumpers as reduction measures at the bridge decks. The considered devices are steel spring, steel spring with additional viscous damper or steel spring with additional friction element. Gap between bridge decks remains. The reduction measure is placed at one end of the neighbouring girders. The considered earthquakes are the 1994 Northridge earthquake and the 1995 Kobe earthquake. For the nonlinear analysis a finite element method is used. The investigation shows that compared to the other measures the best reduction of the pounding force can be achieved with a friction device.

Title Alternative Measurement of root system with growth of oriental pickling melon.
FullText URL 012_119_123.pdf
Author Hirano, Emi| Morimoto, Yuji| Miura, Takeshi|
Abstract It is important to clarify how the soil moisture changes by irrigation and how moisture is consumed by absorption of root, to plan irrigation appropriately in upland field. And, it is thought that clarifying the growth of the root can be important information in the water management, because the amount and the pattern of root water uptake change depending on the growth stage. However, there are not too much a lot of researches that measure the root, in addition, the example intended for crops of 'Gourd family (scientific name:Cucurbitaceae)' is not found. Therefore, for oriental pickling melon, it measured how for the root system to grow up as crop grew every three weeks. The results of this study may be summarized as: 1) Root amount increased with the growth of crops, and the majority of the root existed to 20cm in depth. A lot of rootlets with the role of water uptake existed outside of from 10 to 20cm. 2) Root length has grown up in horizontal and vertical direction at a dash at the stage of growing initial. 3) It was able to be confirmed to the growth of the ground part and the root that the length and amount either also had implications. Moreover, root amount and plant caver ratio drew similar curve.

Abstract 芸術歌曲には、洋の東西を問わず生活の中で古くから歌われてきた旋律に基づく曲が多い。学校音楽教育においてそのような曲を学習する際には、芸術的視点からの表現や鑑賞だけでなく、そのもとになった旋律(以下、元歌)との関係で捉える学習も重要であると考える。そこで本研究では、山田耕筰編作曲「中国地方の子守歌」とその元歌を事例として、芸術歌曲の「こもりうた」と生活の中で歌われてきた「こもりうた」の関係について考察した。その結果、旋律に関しては元歌と山田の編作曲では大きな違いは見られないものの、音楽構造上の大きな相違点が、歌に関する音楽表現の工夫(音域、音質、強弱法、リズム操作、音高操作、テンポ操作)とピアノ伴奏の付加の2点で存在することが明らかになった。

Title Alternative Diallel Analysis of 1,000-grain Weight in Two-rowed Barley Varieties
FullText URL 003_001_063_070.pdf
Author Wu, Jiri| Takeda, Kazuyoshi|
Abstract The inheritance of 1,000-grain weight of two-rowed barley varieties was examined using a reciprocal F1 cross and a half F2 diallel cross among eight parents. The F1 generation was examined in five different ripening conditions i.e., (Ⅰ) control, (Ⅱ) leaf cut, in which all leaves were cut at the heading time, (Ⅲ) Spikelet thinned, in which a quarter of the spikelets were thinned at the heading time, (Ⅳ) dry, in which the plants were grown in a vinyl-film house without irrigation, and (Ⅴ) wet, in which the plants were mist-irrigated every two house in the daytime after the heading to the harvest. The experiment was repeated twice. The F2 populations were grown in the ordinary condition. The average 1,000-grain weight was largest in the dry plot followed by spikelet thinned, control, leaf cut, and wet plots. The 1,000-grain weight was predominantly controlled by the additive genes. The dominance effect was also significant. The large grain weight was controlled by the overdominant genes. Epistasis among the genes controlling the 1,000-grain weight was significant, but the maternal effect was absent. In the F1 diallel, heritability was 0.3~0.6 and 0.2~0.5 in a broad and a narrow sense, respectively. In the F2 diallel, it was 0.9 and 0.6 in a broad and a narrow sense, respectively. In each of the 28 F2 populations, the broad sense heritability was estimated as 0.3~0.8.
