In the first part of the present work the interaction of glycophorin with dimyristoylphosphatidylcholine (DMPC) is studied by freeze fracture electron microscopy, densitometry, calorimetry, and 90° static light scattering. An exothermic lipid/protein interaction energy of W_P=190 kJ•mol^-1 was found by application of the well known Van Laar relation for the displacement of the freezing point and the Gibbs-Duhem relationship. Secondly, the effects of Ca²⁺ on the lipid/protein interaction were studied. Following Ca²⁺ addition a remarkable decoupling of the interaction of the glycophorin head group with the bilayer surface was revealed by densitometry and gold-labeling electron microscopy. It is estimated that about 80% of lipid once disturbed by the adsorption of glycophorin head groups is decoupled after addition of Ca²⁺. Thirdly, the selective interaction of glycophorin with binary lipid mixtures was studied, including the mixtures of DMPC with dimyristoylphosphatidylserine (DMPS) and dilauroylphosphatidylcholine (DLPC), and the mixture of dipalmitoylphosphatidylcholine (DPPC) with DLPC.

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.

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.

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.

Chemical synthesis of (, 24R)- and (, 24S)-1, 24-dihydroxy--vitamin D₃ has been achieved starting with the commercially available dinorcholenic acid acetate. Synthesis involved introduction of the 1-hydroxy group by a reduction of the 1, 2-epoxide generated by epoxidation of the 1, 4, 6-trien-3-one. The side chain on the steroid was then constructed by means of a Wittig reaction followed by introduction of the Δ⁷ bond by standard methods and its protection with 1-phenyl-1, 2, 4-triazoline-3, 5-dione. Subsequent reduction of the hydroxy groups in the steroid side chain followed by reduction of the Diels-Alder addition products yielded the both 24-isomers. The 5, 7-dienes were irradiated and the corresponding vitamin D compounds isolated. Nuclear magnetic resonance was used to identify individual isomers. The (, 24S)-1, 24-hydroxyvitamin D₃ compound bound equally well to the chick intestinal cytosol receptor as 1, 25-dihydroxyvitamin D₃, while the 24R-isomer was approximately ten times less active. In vivo, both isomers were less active than 1, 25-dihydroxyvitamin D₃ ; however, the 24S-isomer was considerably more active than the 24R-isomer approaching the activity of 1, 25-dihydroxyvitamin D₃.

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.

This paper proposes a methodological framework for developing a real-time intelligent decision support system for urban traffic congestion emergency response. To support real-time decision making, the system is required to have the capability to provide an efficient organization of input data and inferred knowledge from all kinds of data sources so as to guarantee the adaptability to changes and the reusability for different congestion situations. For this requirement, we attempt to combine data warehouse with data mining methods in building the framework. Data warehouse provides a well-organized information source for traffic congestion dispersion by means of data collection, analysis, disposal and storage. Furthermore, data mining techniques deal with the set of mixed numeric and non-numeric congestion data and information. In this way, knowledge that represents cause-and-effect dependencies among the congestion attributes are extracted.
