Abstract We have proposed a mathematical model for the micro-dynamics for cultured cells measured with ECIS system for the detection of nanometer-order dynamics of cells cultured on a small gold electrode and could separately evaluate cell-to-cell distance (A) and cell-to-substrate distance (h). For wide applications of this method, we constructed mathematical models which express cell-to-electrode impedances for some kinds of confluent conditions. Based on this mathematical model, we defined new parameters S(A) and S(h) in order to evaluate cell-to-cell distance and cell-to-substrate distance. As the application, we investigated the effect of X-irradiation to bovine aortic endothelial cell (BAEC). We analyzed the micro-dynamics of cells from the impedance of BAEC before and after X-irradiation. It was proved that the stimulation of 100 Gy X-irradiation to the BAEC resulted in the large scale of increase in the cell-to-cell distances (A), and the slight increase in the cell-to-substrate distances (h) accompany with continuous fluctuations.
Abstract Alternative [背景] Electrical Cell-substrate Impedance Sensing (ECIS)は培養細胞の電気的計測により,その微細挙動を評価する工学的手法である。我々はECISを用いてこの微細挙動を細胞-細胞間隙と細胞-電極間隙に分離して推定することが可能な数学的モデルを提案してきた。本研究ではこの数学的モデルを使用して,Ⅹ線を照射した牛大動脈内皮細胞(bovine aortic endothelial cell : BAEC)の微細挙動の経時変化を評価した。 [方法と結果] ECISシステム(Model 1600R Applied BioPhysics)を用いてBAECのコンフルエント到達前後で計測を行い,数学的モデルを構築した。このモデルは細胞の微細挙動を検出するために重要な周波数レンジである1-10kHzにおいて測定結果とよく一致し,Cole-Cole円弧則に従う。さらに細胞-細胞間距離Aの増減に対応する校正定数S(A)と細胞-電極間距離hの増減に対応する校正定数S(h)を導入し,ベクトルインピーダンスの変化に対応した値を算出することで細胞の微細挙動を評価することとした。次に本法によりX線(150kV, 100Gy)を照射したBAECの微細挙動を評価した。Ⅹ線照射細胞では時間経過と共に抵抗成分の変化が支配的なインピーダンスの減少が確認された。この現象はS(A)の大きな増加とS(h)の微小な減少をもたらした。このパラメータの変化は細胞間隙が拡大したことを示しており,Ⅹ線照射による細胞内損傷により細胞密度が低下したと考えられた。 [結論] 本法は培養細胞の微細動態の変化を細胞-細胞間隙と細胞-電極間隙に分けてリアルタイムに定量評価することが可能であり,各臓器の細胞レベルでの薬物の治療効果や Ⅹ線に対する耐性の評価に適応できるものと考える。

Abstract 癌の有力な治療法の1つである放射線治療はシステム全体の許容誤差が±5%と、正確な治療が要求されている。正確な線量を正確な場所に照射されなければならない。そのためには日頃から照射装置のQuality Control が重要である。Beam平坦度の測定はその中でも、重要な項目で1/6月の測定頻度が勧告されている。今回、市販のBeam Flatness Analyzer (7000型 THEBES) を使用する機会を得たので、その基礎的性能であるChamber 相互の感度のちがい、測定値の再現性、識別可能な最小線量について実験を行った。各項目とも誤差が非常に少なく、日常の使用に際してそのデータは十分信頼できるものであることがわかった。
Abstract Alternative Lrradiation, which is one of the effective therapies to Cancer, is required to be accurate within ±5% of the tolerable error of the total system. An accurate dose has to be irradiated accurately at a target volume. For that Quality Control of the irradiation equipment is cotinually important. As the measurement of Beam Flatness is an important item, it is obligated to be measured once a week. In this paper as we have an opportunity to use a Beam Flatness Analyzer sold on a corporation of medical instrument, we experiment about the difference of sensitivity of mutual Chamber which is its basic property, the reproducibility of the measured score, and the minimum value of measuralbe dose. We find that the difference in every item is so small that its data is very reliable in a daily use.

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 Alternative The new three screen-film systems, Kodack INSIGHT system HC/IT-1, Fuji AD system HG-M/UR-1, and Konica EX system XG-S/ES-C for chest radiography were evaluated. In addition, the conventional system Fuji HR-4/Super HR-S was measured for comparison with new systems. The evaluation method is as follows. The image quality characteristics, speed, contrast, resolution and granularity were measured. The sensitivity and contrast were determined by measuring the MTF (modulation transfer function) and NCTF (normalized contrast transfer function). The granularity was estimated by measuring the Wiener spectrum. The speed of the new systems were improved by 22% to 73%. The dinsities at the maximum gradient value were shifted to high density (2.0-2.7). However, they had 10% to 30% less resolution. The other hand, the granularities were improved by 21% to 37% at 1.0 density. These results suggested that the emphasis of new systems was put on improving the image quality of mediastinum region, maintaining performance of the conventional system.

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 Alternative It is necessary to take air attenuation into account when we use inverse square sensitometry to obtain characteristic curve for the mammographic screen-film system at low x-ray energies as used with the dedicated unit. Three kinds of the inverse square sensitometry approach of correcting by air attenuation obtained from effective energy, of correcting by exposure dosimetry and of using modified the technique of Bednarek were employed to investigated the influence of x-ray energy in the characteristic curves for the mammographic screen-film system. In addition, the inverse square sensitometry with the general radiographic unit was employed and the influence of x-ray high energy in the characteristic curves was also investigated for the same screeri-film system. Though characteristic curves and gradient curves of the new inverse square sensitometry were a little lower than the others in high-density region, the curves with three kinds of methods almost coincided. Maximum relative errors of average gradient and maximum gradient for modified the technique of Bednarek were found to be 2.7% and 0.2% among the others respectively. Moreover, maximum relative errors of gradient and maximum gradient for the inverse square sensitometry with the general radiographic unit were 2.7% and 1.5% among three kinds of methods with the dedicated unit respectively. It was considered that the characteristic curves for the mammographic screen-film system were little influenced by x-ray energy and could be obtained only by correcting air attenuation from above results.

Abstract The average glandular dose to glandular tissue m mammography is generally assumed to be a function of beam quality (HVL), x-ray tube target material, tube voltage, breast thickness, breast composition and, to a lesser extent, x-ray tube voltage waveform. The average glandular dose is generally determined from published tables with knowledge of the above function. Tables for a high frequency x-ray generator are not yet published. In our study, the lookup tables for the average glandular dose were made at 28 kV (high frequency x-ray generator), employing a breast simulating tissue (0-100% adipose tissue, 0-100% glandular tissue) phantom for an Mo target - Mo filter source assembly. We tried to estimate breast composition from x-ray mammograms by digital image processing techniques, also using the simulating tissue phantom. Then the system that automatically calculates the average glandular dose from digitized clinical x-ray mammograms was built. It is considered that this system can contribute to objective evaluation of the average glandular dose.
Abstract Alternative 乳房X線撮影法において乳腺組織に対する平均放射線吸収線量,すなわち平均乳腺線量は放射線のリスクの最も有用な測定法であり,現在,乳房に対する線量の評価に用いられている指標である。一般に,平均乳腺線量は線質(HVL),X線管球ターゲット材料,管電圧,圧迫乳房厚さ,乳房構成および(ある程度)X線管電圧波形の関数であるとされている。平均乳腺線量は,上記の関数についての情報を備えた表が公表されており,一般にその表を使って決定されている。近年,インバータ式といわれる高周波X線発生装置が普及してきた。しかし,その装置用の表は,まだ公表されていない。我々の研究では,乳房組織をシュミレートするファントム(0~100%乳腺組織,0~100%脂肪組織)を使用して,28kVでMoターゲット―Moフィルタソースアセンブリーを備えた高周波X線発生装置のために,平均乳腺線量用のルックアップテーブルを作成した。同様に,乳房組織をシュミレートするファントムを使用して,乳房X線写真から,ディジタル・イメージプロセシング技術によって,乳房構成の評価を試みた。そして,ディジタイズされた臨床乳房X線写真から,平均乳腺線量を自動的に計算するシステムを構築した。サンプル数が少ないため断定はできないが,日本女性は,基準構成(50%の脂肪および50%の乳腺組織)と比較すると,脂肪が少ない傾向を分析結果は示唆していた。また,平均乳腺吸収線量の限度は,明確に規定されていないが,American College of Radiology(ACR)は4 mGyなどを推奨している。また日本では,3 mGyが推奨されているが,我々の撮影システムはこれらを十分満足していた。このように本システムは,平均乳腺線量の客観的な評価に寄与するとともに,DR(digital radiography)などに応用すると,すなわちルックアップテーブルをDRのコンピュータに保存しておけば,撮影後すぐに乳房構成および平均乳腺線量を算出できる可能性をもつ。

Abstract 幼小児を含めた若年者の股関節X線撮影検査においては鉛板などで生殖腺を防護して行うのが通常である。男性の場合は生殖腺は体外に露出しているので,それを鉛板で包むようにすればある程度目的は達成される。しかし,女性の場合,生殖腺は骨盤腔内に存在するため,卵巣及び子宮を防護でき診断目的領域にかからないように鉛板を成形し,腹壁上に置いて撮影する。X斬写真上ではグリッドで散乱線を除去しているため,鉛板の陰影がくっきりと撮影され,生殖腺は完全に防護されているように見える。しかし,体内では散乱線によるかなりの被曝があるものと考えられる。そこで今回,鉛板下の散乱線量を鉛板幅及び電圧を変化させ,ファントム内各深さの散乱線量を測定した。その結果,鉛板下の散乱線量が相当量認められ,その量は深さ3~4cmでピークを形成した。鉛板幅による変化は幅が狭いほど線量は大きくなり,電圧による変化は60kVと80kVを比べると80kVの方が多くなった。これを鉛板なしの場合と比較すると,ファントム内意さが増すにしたがい増大した。したがって,臨床において鉛板がずれて再撮影をすることのないよう細心の注意が必要であると考えられた。
Abstract Alternative Usually in a hip-joint radiographic examination for the youth including children, the gonads should be well protected with an appropriate lead shield etc. Since the male gonads are in the outside of the body, if covered with a lead shield, the shield can protect them. However, in the case of the female, since the gonads of exist in a pelvic cavity, the lead shield is cut to a specific pattern so that it can protect the ovaries and the womb, and it is set on the abdomen during the radiographic exposure. Since the scattered radiation on an X-ray film can be removed with the grid, the image of a lead shield is obtained clearly, and the gonads seem to be protected completely. The shield can not protect the gonads of the female from the scattered radiation, though it protects them almost completely from the primary X-rays beam. Therefore, the gonads have radioactive contamination from scattered radiation. Then, in order to estimate the amount of scattered radiation under the lead shield, the dose under the shield was measured by using a phantom in this research, changing lead shield width, the tube-voltage, and the monitoring depth of a phantom. As a results, the dose under the lead shield was observed considerably and showed the peak at the depth of 3 or 4cm. Therefore, it was thought that a careful caution was required for obviating lead shield in clinical.

Author Yamashita, Yuhiko| Kimura, Kunio| Tsugita, Hiroshi| Yokoyama, Fumiyoshi|
Abstract Morphology and formation mechanism of poly (4'-oxy-4-biphenylcarbonyl) (POBP) crystals obtained by solution polymerization were firstly treated. It was concluded that the formation mechanism of the bundlelike aggregates of fibrillar crystals in POBP was fundamentally simillar to that in POB whiskers. Secondly the copolymerization effects of m-acetoxybenzoic acid and 4-(4-acetoxyphenyl) benzoic acid on the morphology of POB whiskers were studied. The experimental results strongly supported our proposal for the formation mechanism of whiskers which was consisted of crystallization of oligomers with a critical length as lamellae from solution and solid state polymerizationof oligomers between lamellae. Finally, the formation mechanism of poly (p-oxycinnamoyl) spherical products during solution polymerization was treated. The formation of these spherical products could be understood by overlapped phase diagram of melting depression curve and consolute curve of oligomers-solvent system.

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 Efficient Chain Extension Reaction of Poly (butylene terephthalate) by using Crystallization
FullText URL 012_167_171.pdf
Author Ihara, Seiji| Shiroma, Hisashi| Yamazaki, Shinichi| Kimura, Kunio|
Abstract Plastics are quite important materials for not only industrial usages but also our daily life. Many plastics are difficult to reuse because they are susceptible to UV, hydrolysis and so on leading to the reduction of molecular weight. Among them, poly (butylenes terephthalate) (PBT) is a valuable materials prepared by polycondensation reaction, and PBT has the same limitation to reuse. Hence, efficient chain extension reaction for recovered PBT has been needed to improve the properties damaged by chain scission. In this study, new chain extension reaction had been examined by using crystallization as pre-treatment. Isothermal crystallization at 161℃ concentrated the chain end-groups on the surface of the crystals, and chain extension reaction at 210℃, which was lower than the melting temperature of PBT, enhanced the molecular weight significantly compared with the reaction over the melting temperature. It concluded that the pre-treatment of crystallization was favorable for the efficient chain extension reaction and this result provided the new technology for the effective reuse of the plastics.

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.
