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.

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.

The anterior cruciate ligament (ACL) plays the primary role in resisting anterior tibial translation. ACL rupture inevitably causes alterations in knee kinematics and long-term functional impairment. The purpose of this study was to evaluate a new surgical technique, subosseous screw-suture anchor surgery (SSSAS), for ACL repair of the knee from a biomechanical point of view. Twelve porcine knees were tested with the ACL intact, cut, and repaired (using traditional Pull-Out method or the SSSAS method) on a mechanical testing apparatus. Tibial translation at four knee flexion angles (0°, 30°, 60°, 90°) under three tibial rotation loads (5 N-m, 0, -5 N-m) was measured to determine knee stability. A laxity recovery ratio was defined to account for individual variations and estimate the repair level. Our findings indicate both Pull-Out and SSSAS techniques significantly decreased AP laxity of the knee joint. In addition, the differences between the intact and repaired knees in the Pull-Out group were significant in all three tibial rotation positions. In the SSSAS group, they were significant at 0° and 90° knee flexion for both neutral and internal rotation positions and at 0°, 30°, and 90° knee flexion in the external rotation position. Concerning the laxity recovery ratio, the SSSAS group had higher laxity recovery ratio than the Pull-Out group. In other words, the fixation by directly fixating the ACL on the femoral interchodylar area instead of the fixation through femoral tunnel could give better outcome in terms of knee stability.

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.

Aim: Macrophage-derived chemokine (CCL) is a member of the CC-family of chemokines synthesized by monocyte-derived macrophages. Previous studies have reported a relationship between CCL and atherosclerosis and the role of histamine in this pathway. Histamine ncreases the CCL expression in human monocytes via the H2 receptor. In this study, we investigated the effects of CCL and the role of histamine in mouse monocytes with respect to atherosclerosis.
Methods and Results: The expression of CCL was investigated in apolipoprotein E (apoE)-deficient mice. The mice had high serum concentrations of CCL and their atherosclerotic lesions contained abundant levels of CCL. In addition, when the mouse monocyte cell line (J774A.1 cells) differentiated into macrophage-like cells, the cells showed a similar expression of CCL and reduced expression of H2 receptors. Histamine is synthesized from l-histidine by histidine decarboxylase (HDC) in a single enzymatic step. HDC knockout mice were compared with apoE/HDC double knockout mice. The findings indicated that the expression of CCL in atherosclerosis models is under the influence of histamine. In addition, in vitro studies using J774A.1 cells and an in vivo study using histamine receptor knockout mice showed that histamine stimulates the CCL expression via the histamine H2 receptor.
Conclusions: The current results support our previous CCL studies in the setting of human atherosclerosis and suggest that this molecule is involved in the atherogenic processes in a mouse model of atherosclerosis.
