Thalassomyiaは雌雄ともに有翅の海棲ユスリカで, 1866年以来, ヨーロッパ, アフリカ, 南米のほか, ハワイ, ガラパゴス, マーケサス, サモア等の太平洋各地及び香港等から報告されたが, 本邦では1955年トカラ列島の中之島からThalassomyia japonicaが記載されるまで全く知られていなかつたものである.本属は歴史的に古いだけでなく, 近縁のTelmatogetonやParaclunioとともに海棲ユスリカとして重要な一群をなすが, 従来の研究は充分とは云いがたく, 日本産のものに関しても詳細な知見に欠けるところが多かつた.筆者は今回, 琉球列島の海棲昆虫調査にあたり, 八重山群島の石垣島でThalassomyia japonicaを多数採集し, 本種に関する多くの疑問点を明らかにすることができた.本論文では, 本種の形態的特質について多くの点を補足し, 細部にわたつて外国産の既知種との比較検討を行ない, 種の類縁関係を明らかにすることにつとめた.なお, 従来Thalassomyiaの習性に関しては末知な点が多かつたが, 筆者は本種について, 成虫の出現時間, 運動習性, 静止姿勢, 交尾, 産卵等を観察し, 多くの特性を明らかにした.特に本種での所見では, 少なくとも日本産のTelmatogeton2種と比較した場合, 習性の点でも大きな相異の認められたことは興味深い.

A case of a 69 year old female with primary gastric choriocarcinoma was presented with spesial reference to histogenesis by using the immunohistochemical tequnique (PAP method). The gastric tumor in this case was histologically diagnosed as choriocarcinoma coexistent with adenocarcinoma. From hormonal standpoint, the diagnosis was confirmed by recognition of high HCG titers in both the serum and tumor. The primary focus of the choriocarcinoma was detected neither in the genitourinary tract nor in the mediastinum in spite of a thorough autopsy. By PAP method tumor cells of choriocarcinoma showed high positive reaction only to anti-HCG antiserum and less positive to anti-HPL and SP1 antisera in contrast to those of uterine choriocarcinoma with high positive reaction to anti-HCG, HPL and SP1 antisera. Tumor cells of adenocarcinoma showed positivity to anti-CEA and anti-AFP antisera by the same method. These results indicate that gastric choriocarcinoma might be functionally defferent from gestational choriocarcinoma. Moreover, tumor cells of adenocarcinomatous lesion have some resemblance to embrynal carcinoma morphologically and immunohistochemically. Therefore, the origin of gastric choriocarcinoma seemed to be morphological retrodifferentiation of tumor cells to embryonal ectoderm such as trophoblastic cells.

The genetic diversity of the mangrove tree species Kandelia candel and Bruguiera gymnorrhiza in the Southwest Islands of Japan was investigated. These islands are located at the periphery of the distribution area of the two species, and their populations are relatively small. Allozyme analyses of 17 loci in K. candel and 13 loci in B. gymnorrhiza revealed very little genetic variation in both species. At the species level, the proportion of polymorphic loci wad 4.2%, the average effective number of alleles per locus was 1.02, and the average expected heterozygosity was 0.012 in K. candel. The corresponding figures for B. gymnorrhiza were 9.0%, 1.06 and 0.035, respectively. However, the coefficients of genetic differentiation among the populations were high (G_<ST>=0.165 for K. candel and 0.253 for B. gymnorrhiza). The genetic variation and habitat area of K. candel on Amami Island is greater than on the islands Okinawa and Iriomote. The genetic variation and habitat area of B. gymnorrhiza is greater on Iriomoter Island than on the islands Okinawa and Amami. The level of genetic variation in both of the species might be related to their population sizes.

We evaluated the allergen inactivating effect of colloidal silica by performing enzyme-liked immunosorbent assay (ELISA) whose wells were coated with 150 ng/mL of Japanese cedar pollen allergen (Cry j 1) or mite allergen (Der f 2). The allergens were almost 100% inactivated by 100 μg/mL of colloidal silica having a particle size 5 nm, and the inactivating effect was increased by aluminum binding to the surface of the colloidal silica. The results show that colloidal silica is a promising material for allergen inactivation. Since colloidal silica forms an insoluble nondispersive solid when dried, it is expected that airborne allergens can be reduced by binding them to colloidal silica.

Zearalenone (ZEA) is an estrogenic mycotoxin produced by Fusarium sp., and its production on corn and small grains during storage has been of considerable concern. For sensitive ZEA detection, we applied an open sandwich (OS) immunoassay that can noncompetitively detect monovalent antigens utilizing an antigen-induced enhancement of the VH/VL interaction. We cloned the VH and VL cDNAs of anti-ZEA mAb to a split-Fv phagemid pKST2, and firstly both VH and VL fragments were displayed on M13 phage p9 and p7, respectively, using an amber suppressor, TG-1, as a host. The split-Fv phage showed specific binding to immobilized ZEA, which was well inhibited by free ZEA. Then, the VH/VL interaction and its antigen-dependency were analyzed using a non-suppressor HB2151 as a host to produce VH-displaying phage and his/myc-tagged soluble VL in the culture supernatant. By capturing VL with an anti-myc or -his antibody and probing bound VH-phage, ZEA was successfully detected with a superior detection limit as well as a wider working range than those of a competitive assay. Also, essentially the same results were reproduced with purified VH-alkaline phosphatase and MBP-VL fusion proteins.

シロウリガイ類は深海から採集すると通常2, 3日しか生存せず, 飼育を試みた報告は皆無であった。本研究では, シロウリガイ類の飼育の試みとして, 良好な健康状態で採集し, かつシロウリガイ類の共生細菌のエネルギー源(泥中の硫化水素)を確保するために, 圧力以外の現場環境をできる限り維持した状態で採集する装置のMTコアを開発した。また, シロウリガイ類は高酸素濃度に弱いため, 溶存酸素濃度制御装置により低酸素濃度環境を維持する飼育システムを製作した。シロウリガイとエンセイシロウリガイをそれぞれ相模湾初島沖水深1,150m~1,160mの地点, 石垣島沖の黒島海丘の643mの地点で採集した。採集したシロウリガイは約1週間で死亡したが, 黒島海丘のエンセイシロウリガイは17日間生存した。また, エンセイシロウリガイでは2回放卵が確認された。以上のことから, エンセイシロウリガイは飼育が容易な種と考えられた。

BACKGROUND: Few studies have examined the association of perceived health with socio-economic status, especially income, and social isolation and support in Japan. The purpose of this study is to clarify the associations among perceived health, lifestyle, and socio-economic status, as well as social isolation and support factors, in middle-aged and elderly Japanese.METHODS: Subjects were 9,650 participants aged 47-77 years who completed a self-administered questionnaire in 2000 in the second survey of a population-based cohort (the Komo-Ise study). The questionnaire included items on sociodemographic and socio-economic factors, social isolation and support, lifestyle, past history of chronic disease and perceived health. Perceived health was dichotomized into excellent or good health and fair or poor health. A logistic regression analysis was used to determine the odds ratios of socio-economic status, social characteristics and lifestyle in relation to self-reported fair or poor health.RESULTS: We found that household income, physical activity, sleeping, smoking habit, and BMI had a strong association with self-reported fair or poor health in middle-aged and elderly Japanese men and women. Male subjects tended to report fair or poor health as household income decreased. The results for women differed in that social isolation and low social support had a stronger association for selfreported fair or poor health than low household income.CONCLUSIONS: The results indicated that perceived health was associated with socio-economic and social characteristics among middle-aged and elderly residents in Japan.

Learning from tree-structured data has received increasing interest with the rapid growth of tree-encodable data in the World Wide Web, in biology, and in other areas. Our kernel function measures the similarity between two trees by counting the number of shared sub-patterns called tree q-grams, and runs, in effect, in linear time with respect to the number of tree nodes. We apply our kernel function with a support vector machine (SVM) to classify biological data, the glycans of several blood components. The experimental results show that our kernel function performs as well as one exclusively tailored to glycan properties.

This paper proposes that the definition of the situation should be a central concept to the sociological investigation of teachers' behaviours and that the theory of the teachers' working process should be built to locate the teachers' educational behaviours in the public educational system within the capitalistic socio-economic structure. The role and role-conflict is negatively examined in terms of its conceptual ambiguity and its human and social model. The definition of the situation proceeds from the classification and categorizing of the immediate events (1st phase) to the evaluation of the 1st phase, and to the planning of the actions and its legitimation (2nd phase). It varies with the actor's orientation of actions (goal, intention, interests at hand), the actor's environment (material conditions, social and cultural structures) and his or her predisposition (identity, commitment, ideology). Sociological studies of teachers' behaviours have focused upon the teachers' perception of the pupils (1st phase), and their planning of actions and legitimation (2nd phase). Teachers' perception of pupils has been considered to be a problem of the teachers' typification of the pupils by H.S. Becker, D. Hargreaves, R.C. Rist, N. Keddie, G. McPherson, P. Woods, and other symbolic interactionists. The teachers' planning of actions has been approached in terms of the strategies by A. Hargreaves, P. Woods, A. Pollard and other new sociologists of education. The teachers' legitimation of their educational behaviours has been approached in terms of the frame, structure and structuring (H. Mehan, A. Edwards, V. Furlong, G.C.F. Payne) and in terms of the front performance or impression management (E. Goffman). In this paper, each aspect of the above described teachers' behaviours is examined and it is suggested that the exploration of the dialectical relationship between the teachers' orientation of action, their environment and their predispositions is needed to approach the process of the teachers' definition of the situation. Finally, it is contended that a macro-approach is needed to place the teachers' educational behaviours in the public educational system, because the teachers' educational behaviours are supposed to lie in the dilemma between the teachers' working process and the process of the man-power production loaded upon teachers by the public educational system.

This paper proposes a method for creating the viewers' side annotations that reflect viewers' attentions on TV dramas. Internet bulletin boards are filled with large amount of viewers' dialogues concerning TV programs. Our approach is to extract the viewers' attention embedded in these dialogues and express them in the form of the graphical structures called attention graphs. The attention graphs act as viewers' side annotations. Viewers' side annotations assist in providing viewers with hints to locate their favorite scenes in full-length TV programs. In general, Internet bulletin boards are described without any particular order and are expressed in a poor grammatical manner. Our approach is to statistically recognize the notable frequencies of the words which represent viewers' attentions out from such unstructured documents. Attention graphs are the outcome of this approach. Attention graphs are evaluated by three types of tests. The test results demonstrate that attention graphs sufficiently act as viewers' side annotations, in terms of pointing out which scene the viewers pay attention to and clarifying how deeply viewers are impressed by the scenes.

This paper reports the ecotoxicological study of “tetradecanoic acid, 2-sulfo-, 1-methylester, sodium salt (C14MES)”. This salt was synthesized by sulfonating 1-methyl tetradecanoic acid derived from palm oil and coconut oil with sulfur trioxide. The tests were attempted in accordance with the OECD (Organization for Economic Cooperation and Development) Guidelines for the Testing of Chemicals. The 72 h ErC50 exceeded 100 mg/L in the alga growth inhibition test. In the daphnia acute immobilization and reproduction tests, 17.2 mg/L of 48 h EC50 and 4.10 mg/L of NOEC were derived, respectively. These ecotoxicities of C14MES were equivalent to or lower than that of other similar anionic surfactants, such as LAS (linear alkylbenzene sulfonate) or AOS (alpha olefin sulfonate).
