帯状疱疹に対するRo-8181の有効性, 安全性および有用性を検討するため, ヒト血清アルブミンを対照薬として, 二重盲検比較試験を行つた。皮膚症状の観察項目別の改善率では, 水疱·膿疱において投与開始後5日目でRo-8181群70%, placebo群50%で, 両群間に差(p<0.05)が認められた。皮膚症状改善度の推移を著明改善以上の症例についてみると, 投与開始後4日目の著明改善率はRo-8181群8%, placebo群0%であり, Fisherの直接計算法で両群間に差(p<0.05)が認められた。また, 投与開始後5日目の著明改善率はRo-8181群15%, placebo群3%であり, κ² 検定で両群間に差(p<0.05)が認められた。主治医による有効性の判定ではU検定でRo-8181群が優れている傾向が認められた。主治医による安全性の判定では副作用発現率がRo-8181群83%, placebo群14%であり, U検定で両群間に差(p<0.001)が認められた。主治医による有用性の判定ではU検定で両群間に差は認められなかつた。以上の結果より, 帯状疱疹に対し, Ro-8181は皮疹のうち水疱·膿疱に対して有効であり, 主治医判定でも有効性が認められたが, 安全性については本薬剤の耐薬性が示されたものの副作用の発現率が高かつたため, 有用性は高くないと考えられた。

Intracerebral injection of vegetative myxamoebae of strains of Polysphondylium pallidum caused 80 to 100% mortality in mice, whereas a 30 to 50% mortality occurred with strains of Dictyostelium giganteum and D. mucoroides. Death is attributable to an unidentified toxic factor. Histopathologically a giant cell formation was seen in the spleen of mice. This cell was different from Langerhan's or foreign body giant cell. Rats injected intracerebrally behaved similarly. Intranasal instillation of myxamoebae in guinea pigs caused transient pneumonia. Myxamoebae do not multiply in the brain tissues of mice or rats, or in the lungs of guinea pigs.
Intranasal instillation of vegetative myxamoebae is less pathogenic than free living amoebae like Hartmanella culbertsoni, H. rhysodes, Naegleria sp. (Culbertson strain HB-1), or Naegleria aerobia.

The Japan Society for Occupational Health (JSOH) recommends the Occupational Exposure Limits (OELs) as reference values for preventing adverse health effects on workers caused by occupational exposure to chemical substances, continuous or intermittent noise, impulsive or impact noise, heat stress, cold stress, whole-body vibration, hand-arm vibration and time-varying electric, magnetic and electromagnetic fields and ultraviolet and ionizing radiation.

The nd Annual Meeting of Japan Society for Science Education (JSSE) was held on July 29-31, 1998 at Tokyo Gakugei University in western suburb of Tokyo with about 290 registrants under the main theme of "Towards Implementation of Science Curriculum for Construction of Creation and Symbiosis." Number of papers over 210 were presented in both main sessions and general presentations. There were two symposiums, one lecture, one forum, one international forum, one workshop, three sessions of themes set by the steering committee and ten sessions of themes set independently by members of JSSE in main sessions. Also, there were many other general presentations. Many papers were presented coping with the main theme. They were a lecture related to learning and creativity based on advance of brain, and many presentations related to symbiosis such as relation between in-door and out-door school activities, school based research activities such as curriculum development, and way of finding new methodology of research on classroom, consistency of curriculum through elementary to high school, pre-service teacher education, and so on. Contents of claims and discussions in every presentation in main sessions are summarized in this paper.

The resultative construction in the fifth sentence pattern is a special language structure in Germanic languages such as English, German and Dutch. This construction has been in common use since the late Middle English period. The previous study by Visser (1967: An Historical Syntax of the English Language I-IIIb) indicates there were only three examples of the resultative constructions in Old English and there were several examples in Middle English. In this paper, I reexamine the previous study conducted by Visser (1967) and Kamiya (2007). I attempt to examine the usage and frequency with which small clauses appeared in Old English using the York-Toronto-Helsinki Parsed Corpus of Old English Prose (YCOE). I then confirm whether the resultative construction exists in the small clauses appearing in the YCOE manually.

A financial market is a diversified dynamical system with many constraints, and price movements are modeled in terms of the micro properties of each transactions and the macro properties of dynamical systems. These two properties must be bridged by the multiplicity. The model forcuses on the size of tick and the number of transactions with the price movement compared with the previous transctions and explains stochastic nature of short-term volatilities and persistently stable long-term volatilities as a results of unique behaviour of heterogeneous market participants.

SAKATA Shōichi, known as a physicist who contributed significantly to the development of the theory of elementary particles, held a sincere belief in the Marxist philosophical view of nature. He acquired the basic core of this worldview by reading the classics of Marxism as a youth and later added original insights via correspondence with others or development of his own inquiry into the microscopic world. Several visits to the Soviet Union and the People's Republic of China also deeply impressed Sakata. This article examines the features of his understanding of Marxist natural philosophy and the factors that helped him establishing it. By focusing on Sakata's experience of the international/domestic exchange with Marxists, this study will also reveal how the orthodox and unique part of his understanding of dialectical materialism divided and conjoined.

DiGeorge syndrome (DGA), velocardiofacial syndrome (VCFS), and conotruncal anomaly face syndrome (CTAF) are frequently associated with q11.2 deletion syndrome. We report two cases of q11.2 deletion syndrome. Two patients had cleft palate, and facial dysmorphism. Fluorescence in situ hybridization (FISH) was used to show deletion of chromosome q11.2. Palatoplasty was performed at about two years of age with the patients under general anesthesia. The postoperative course was uneventful in both patients.

The purpose of this study is to investigate the changes in cold/warm thresholds of women with advancing age. Tamura et al. have developed a new device for measuring the cold/warm thresholds as a method of evaluating sensitivity of the human skin. By using the device, changes in the cold/warm thresholds in adult women were investigated. Sixty-eight healthy female subjects aged 20 to 88 years old wearing only under pants and brassiere lay in a supine position on a saran bed and their cold/warm thresholds were measured over 26 body regions under the condition of 28°C ambient temperature and 50%RH. The results showed that the cold/warm thresholds of the leg, foot and sole were large and those of the forehead, cheek, chin and palm were small for each generation. The cold/warm thresholds for the elderly women were larger than those for young women. In particular, the threshold of the leg was significantly larger for the elderly women than it was for the young women, and it increased with advancing age. The cold/warm thresholds of the leg, foot, and sole were found to be obviously age-dependent. The cold/warm threshold values of the trunk were between those of the face and lower extremities, with the exception of the anterior shoulder. As a result of principal component analysis, the first component was interpreted as a size factor which explained the intensity of the cold/warm threshold sensitivity of the whole body. The value of the first component of each subject increased with age in the 60's to the 80's. The second component obtained from the cold/warm thresholds analysis was interpreted as a factor which explained the contrast between the sensitivity of the anterior shoulder and chest, and buttock and foot for the cold sensation and the contrast between the sensitivity of the posterior leg and sole, and buttock and anterior neck for the warm sensation.
