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。

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.

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 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.

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.

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.

Background: IL-

is an IL-10-family cytokine that regulates chronic inflammation. We investigated the role of IL- and its receptor, IL-R1, in the pathophysiology of chronic rhinosinusitis with nasal polyps (CRSwNP).

Methods: IL-

and IL-R1 protein and mRNA expression in NP and in tissues (UT) from CRS and non-CRS patients was examined using immunohistochemistry and real-time PCR, respectively. Dispersed NP and UT cells were cultured with the Staphylococcus aureus exotoxins, staphylococcal enterotoxin B and alpha-toxin, following which exotoxin-induced IL- levels and their association with clinicopathological factors were analyzed. Effects of IL- on MUC1 expression and cytokine release in NP cells were also determined.

Results: IL-

and IL-R1 in NP were mainly expressed in infiltrating inflammatory cells and in epithelial cells, respectively. IL- mRNA levels in NP were significantly higher than those in UTs from non-CRS patients whereas IL-R1 levels were conversely lower in NPs. NP cells produced substantial amounts of IL- in response to exotoxins. Exotoxin-induced IL- production by NP cells significantly and negatively correlated with the degree of local eosinophilia and postoperative computed tomography (CT) score, whereas conversely it positively correlated with the forced expiratory volume in 1s (FEV1)/forced vital capacity (FVC) ratio. IL- significantly enhanced MUC1 mRNA expression in NP cells. IL--induced MUC1 mRNA levels were significantly and positively correlated with IL-R1 mRNA levels in NPs. Conclusions: These data suggest that imbalance of IL-/IL-R1 signaling regulates the pathogenesis of CRSwNP, including local eosinophilia, via alteration of MUC1 expression.

We report three cases of q11.2 deletion syndrome (CATCH; cardiac defects, abnormal faces, thymic hypoplasia, cleft palate and hypocalcemia with chromosome q11.2 deletion) with various complications including hearing loss and nasopharyngeal problems. All three cases we report here had congenital cardiac defects. Two of the three cases had cleft palate, one overt and the other submucoals. Although one of the three cases had a normal hearing level, the other two were almost deaf, one with and the other without inner ear anomalies. The former case was prescribed a hearing aid, and for the latter case, cochlear implantation operation was conducted at the age of three years and seven months. Both of these patients have successfully developed communication skills.
CATCH shows a variety of phenotypes, including hearing loss and nasopharyngeal malformations, either of which may disturb speech ability and thus, furthermore, mental development of the child. However, this condition may be improved by early and adequate intervention. Thus, otolaryngologists should be familiarized with the typical facial abnormality and most frequent manifestations of this syndrome, and be ready to treat patients with q11 deletion, providing them with intensive and individualized prescription at their early stages.

目的:現在尿路上皮腫瘍のスクリーニング法としては尿細胞診が広く用いられているが細胞異型の弱い腫瘍の場合には検出感度が低く偽陰性が問題となる. 近年開発された尿中腫瘍マーカーのNMPは, 迅速に結果が得られ早期の尿路上皮癌を確認できるとされスクリーニングに広く用いられつつある. 今回われわれは, 尿中NMP値と尿細胞診結果を組織診断および膀胱鏡検査と比較し, 今後の尿路上皮スクリーニング法について検討したので報告する.
材料および方法:2000年7月から2002年4月までに当院泌尿器科より提出された外来自然尿675例について尿細胞診およびNMP (コニカMatritech UNMPテストキットELISA法) を比較検討した.
結果:臨床的および組織学的に31例の癌 (G1: 8例G2: 19例G3: 4例) が確認された. このうちNMPでは陽性が17例, 細胞診では14例, 陰性はNMPでは14例, 細胞診では17例であった. 細胞診では明らかな偽陽性症例 (+) はみられず, 疑陽性症例 (±) 17例に対しNMPでの偽陽性数は96例であった. これらの要因として細胞診で炎症や結石などにより細胞異型を示していたものがあり, NMPでは白血球成分の多い検体で高値を示していた.
考察:今回の検討で尿細胞診では検出感度は低いが特異度が高く診断には欠かせない検査である. 一方, NMPはG1の癌検出が細胞診に比べ優れているが, 膿尿などの白血球成分の多い検体では偽陽性結果が多く細胞診結果と乖離するためNMPと尿細胞診との併用が望ましいと思われる.
