    　View Summary

    Four kinds of surfactants, sodium laurate, sodium myristate, sodium palmitate and sodium oleate were used to study the effects of surfactant coatings on the lifetime and attenuation of microbubbles. The changes in the size distribution of microbubbles prepared with these surfactants in saline were measured with a Coulter Multisizer (Coulter Electronics Ltd., Luton, UK). Frequency characteristics of ultrasonic attenuation of the microbubble suspensions were measured between 400 kHz and 6 MHz. From the changes in attenuation in the microbubble suspensions over time, it was found that the lifetime of microbubbles in a suspension also depends on the frequency of the irradiating ultrasound. The effect of surfactants on the frequency characteristics of attenuation was also studied, and characteristics of the surfactant coating, including shell elasticity and shell friction parameters were calculated from the measurement results. Microbubbles produced with sodium palmitate had the longest lifetime and the smallest average size. The shell had very little effect on the ultrasonic properties of microbubbles produced with sodium palmitate, suggesting that the sodium palmitate microbubbles behaved ultrasonically as free microbubbles.

    　View Summary

    The departure of speckle magnitude from Rayleigh statistics was applied to examine insonated phantoms with both low and high concentrations of scatters. A mathematical model, the K distribution of Jakeman, was used to characterize non-Rayleigh statistics. This model contains a parameter, alpha, which characterizes the clustering of the scattering sites in a medium. It is shown from phantom experiments that alpha is linearly proportional to the log-scaled scatterer concentration in a range from about 1 to 30 scatterers per sample volume.

    　View Summary

    It has been about thirty years since China started the open-door policy, when the number of students coming to study in Japan started to increase. Along with the Japanese Government's policy of accepting 100,000 foreign students, students from China have become the largest group of the foreign students' body. On the other hand, Japanese students have become the second largest group among foreign students in China, as Japan and China have developed closer cooperative ties. This study aimed at painting a precise picture of intercultural adjustment of both Chinese students in Japan and Japanese students in China in the time when environment around them have changed drastically.
    There were three major characteristics in this study.
    First, it employed an interactive research method. Students' experiences in both Japan and China were examined from a comparative perspective, thus more objective evaluation became possible. Second, longitudinal research of three years made us possible to grasp the day-by-day variation of the process of intercultural adjustment. Third, participatory approach enhanced the effectiveness of this research. All members of the research team were involved in education and counseling for foreign students. Furthermore, students who became the target of the research also actively participated in the research by recommending improvements for policies on foreign students and intercultural programs. The credibility of the survey result was strengthened, while trustful relations had been built between those who researched and those who were researched.
    There are three points in the major accomplishment of the research. First, it could accumulate huge quantities of questionnaire result, students' diaries, interview notes, and minutes of workshops. Second, it made a comparison of the first generation and the second generation of students from China and Japan, thereby revealed problems and adjustment strategies of respective generations. Third, the effectiveness of a new approach for studying abroad, double-degree program, was tested. The accomplishment of this research is expected to be widely utilized in research on foreign students in the future.

    　View Summary

    Two method of (a) and (b) were basically investigated to design site-targeted ultrasonic contrast agent. In method (a), a microbubble tagged with biotin is used to localize and characterize an avidin-coated surface of tumor. In method (b), a magnetite incorporated microbubble can be localized to tumor with the aid of an extracorporeal magnet. We confirmed that site-targeted microbubble in all of both methods had the potential to localize the particular target under the condition where the flow is stopping. We also confirmed that these site-targeted microbubbles had the potential to localize the target under slow flowrate by using the blood vessel model that was made to imitate the flow of actual blood. But, it became clear that the targeting ability decreased remarkably with increasing the flowrate in the blood vessel model. Therefore, while we were continuing to study to overcome the problems mentioned above, the study of the new method applying the acoustic cavitation was started. Inside the space of acoustic cavitation where high temperature and high pressure are generated, a water molecule splits into radicals H2O → H^+ + OH^- producing hydroxyl radical OH^-. Microbubbles produced by the acoustic cavitation had also excellent characteristic of scattering, because acoustic impedance of microbubbles were quite difference from Surrounding organization. As the result, improvement of quality of ultrasonic image is expected. Namely, if the acoustic cavitation is generated near tumor selectively, We will be able to observe the process of the ruin of cancer cell by active oxygen with ultrasonic diagnostic equipment. Prior to our substantial evaluation, we used an ESR (electron spin resonance device) to make a qualitative evaluation of OH radicals produced by the acoustic cavitation generator. Next, suppression of proliferation of cancer cells with ultrasound exposure was studied in our laboratory. An ultrasound exposure experiment was performed on a culture of cancer cells of mouse T lymphoma (EL-4) in a flask. We confirmed that the number of cancer cells did not change remarkably immediately after exposure and increase the number of cells was suppressed remakably with the lapse of time during 24 hours after exposure

  • 微小気泡超音波造影剤を利用した超音波血管造影システムの研究

    　View Summary

    超音波造影剤として使用する微小気泡の非線形的挙動と高調波発生に関するメカニズムについて検討を行った。超音波照射によっても破壊されにくく、高調波の発生しやすい駆動周波数の検討を行い、駆動周波数を気泡の共振周波数の半分にすることが有効であることを示した。また、照射音圧と気泡寿命の関係について実験を重ねた結果、当研究室で開発した界面活性剤コーティング膜を有する微小気泡の場合、約30kPa〜100kPaの照射音圧の時に最も第2高調波の発生が効率的であった。100kPaを越えると気泡が破壊され、30kPa以下では十分な非線形的挙動を生じないので、第2高調波の発生も不安定になることがわかった。これらの検討の過程において、従来のRPNNPモデルを修正して、コーティング膜の影響や気泡周囲の液体の圧縮性を考慮できる新しい非線形微分方程式を提案した。これによって、高い駆動周波数でも実験と数値計算の結果が良く一致するようにできた。また、取扱いが容易で高調波の励起、検出に最適なPVDF高分子圧電フィルム、音響整合層およびPZT圧電セラミック振動子を積層にしたハイブリッド超音波プローブを提案し、その試作と機能確認も行った。さらに、受信回路(第2高調波抽出回路)の開発および試作を行った。当研究室製の界面活性剤コーティング膜を有する微小気泡超音波造影剤を用いて、これらのシステムの機能確認実験を行った。実験においては、比較対象として第2高調波を発生しにくいカーボンマイクロビーズを採用した。超音波プローブをスキャニングして、これらのサンプルを満たした容器内の映像化実験を行った結果、非線形的挙動の強い当研究室製の界面活性剤系微小気泡超音波造影剤の存在する領域と第2高調波を発生しにくいカーボンマイクロビーズしか存在しない領域との違いを明確に表現でき、本研究で提案した超音波血管造影システムの有効性を確認することができた
