  • Analysis of an Inactivated Lg-FLO1 Gene Present in Bottom-Fermenting Yeast

    SATO Masahide , MAEBA Hideo , WATARI Junji , TAKASHIO Masachika

    During the course of investigating a flocculation-related gene of a bottom-fermenting yeast, we identified a new Lg-FLO1 homologue which contains the N-terminal domain of the Lg-FLO1 gene. The results of the partial DNA sequence analysis of the amplified product obtained by inverse-PCR suggested that the homologue contains a sequence present in the YIL169c (chr. IX of Saccharomyces cerevisiae). Southern blot analyses using the VTH1, HXT12, SDL1 and UBP7 genes as probes for chr. IX strongly indicated that an approximately 20-kb region from the YIL169c ORF to the left telomere in chr. IX translocated to the Lg-FLO1 ORF region in chr. VIII of bottom-fermenting yeast. This translocation might convert a flocculent cell to a non-flocculent one.

  • Penetration of Infrared Radiation Energy into Model Foods  [in Japanese]


    The effect of the penetration of infrared radiation energy into food on the temperature was studied. Model foods of 1.2% agar gel, 1.2% agar+5% cornstarch gel and fish paste were each irradiated by a halogen heater and two types of ceramic heater. The transient temperature and the temperature profile near the surface of each food model were measured. The experimental results and the thermal diffusivity of a sample were used to estimate the radiation energy applied to the food. The halogen heater affected the heat transfer in the range of 1-3 mm below the surface, while the ceramic heater had no effect deeper than 1mm. It was found that the penetration of near-infrared radiation energy was deeper than that of far-infrared energy, and that increasing penetration accelerated the temperature rise within the food sample.

    The antidiabetic agent troglitazone was given to groups of 4 cynomolgus monkeys per sex at 300, 600, or 1200 mg/kg daily by gavage for 52 weeks. A group of 4 monkeys per sex received vehicle alone and served as controls. Emesis and soft stool or diarrhea occurred sporadically in all troglitazone-treated groups, but did not compromise animal health. There were no effects on body weight or food consumption, or ophthalmologic, electrocardiographic, or echocardiographic parameters. Erythrocyte count, hemoglobin, and hematocrit decreased 8% to 16% in males at all doses and serum cholesterol decreased 30% to 46% in both sexes at all doses. Urinary ketones were increased in several animals at 600 and 1200 mg/kg. Absolute and relative liver weights increased at all doses in both sexes by 40% to 71%. The only microscopic change attributable to troglitazone treatment was minimal to mild bile duct hyperplasia in males at all doses and in females at 600 and 1200 mg/kg. No differences in systemic exposure were apparent between sexes. Over the dose range tested, AUC<sub>(0-24)</sub> values were 27 to 102 μg·hr/ml of troglitazone, 401 to 2060 μg·hr/ml of its sulfate conjugate, and 34 to 312 μg·hr/ml of its quinone metabolite. Therefore, oral administration of troglitazone to monkeys at 300, 600, and 1200 mg/kg for 52 weeks resulted in significant systemic exposure, with only minimal gastrointestinal, hematologic, and hepatic effects.<br>

  • A cytogeographical study in Hydrangea paniculata Sieb. (Saxifragaceae s. l.) in Japan

    FUNAMOTO Tsuneo , OGAWA Makoto

    Five hundreds and forty-one samples of Hydrangea paniculata were collected in 362 sites in the Japanese Archipelago. They showed the chromosome numbers of 2n=36, 54, 72 and 108, that were diploid, triploid, tetraploid and hexaploid, respectively. The chromosome number of 2n=54 was reported here for the first time, and the other chromosome numbers verified the previous reports. The plants with the chromosome number of 2n=36 studied were distributed in the central part of Chugoku District and Ishizuchi and Tsurigi Mountains in Shikoku District. The plants with the chromosome number of 2n=72 studied were distributed in the central parts of Tokai, Kinki, Chugoku, Shikoku and Kyushu Districts. The plants with the chromosome number of 2n=108 were distributed in the parts other than the central parts of Kinki, Tokai, Hokuriku, Eastern Honshu and Hokkaido District. The plants with the chromosome number of 2n=54 were distributed in Mt. Tebako, Kochi Prefecture, Shikoku District and Mt. Imizu, Okayama Prefecture, Chugoku District. Near the habitat border among the cytotypes at higher altitude showed more diploid plants (2n=36) than tetraploid plants (2n=72) and more tetraploid plants than hexaploid plants (2n= 108).

    The Japanese language Education Project in local areas has been developed over 7 years since 1994 to 2000 by the Agency for Cultural Affairs (Bunka-cho), in 8 local areas in Japan Nishihara-town in Okinawa was one of them, and the last one of this nationwide project The purpose of the project was to support the lives of foreign residents and the like in local areas, and to assist the town in creating a multicultural society where all kinds of people co-exist comfortably, in a manner which fits the characteristics of the area Two years had been allocated to the project in Nishihara-town, and the project included offering Japanese language classes, cultural exchange salons and other activities One of them was to develop Japanese Language Teaching Materials. Goals for the project were to develop resource materials suitable to Japanese language learners in the area, material which will easily deepen the understanding of Okmawan culture with pleasure, and material which is ready to use and easy to apply, to help learners to interact with local people. In this paper, we discuss the results of a needs survey, the analysis of materials developed in other areas, the process and discussion of making the material including syllabuses, the results of the evaluation of the material, and so forth.

  • Terateleotris, a New Gobioid Fish Genus from the Laos (Teleostei, Perciformes), with Comments on its Relationships

    SHIBUKAWA K , Iwata Akihisa , Sinthavong Viravong

    A new gobioid genus, Terateleotris, is described for the sleeper species, previously known as Odontobutis aspro Kottelat, 1998,from the Xe Banghai basin. Laos. This is the third known gobioid genus bearing a lateral-line canal extending onto body, and the only genus with typical sleeper-like appearance within those three.T. aspro is redescribed, based on six newly obtained specimens, including soft anatomy and osteology. Terateleotris is clearly nested within the basal gobioid assemblage that includes the rhyacichthyids and odontbutids, owing to the lack of several modifications in scales, cephalic sensory canals, axial skeleton and shoulder girdle, all of which are found in the more specialized gobioids (e.g., Gobiidae). We, however, failed to adequately classify it into any known supra-generic taxon, because such taxa have vaguely defined limits, particularly the Odontobutidae.

    解離性脳動脈瘤は, 画像診断の進歩に伴って, 近年注目を集めている疾患の一つである.今回われわれは水泳中に虚血症状で発症し, 経過中にクモ膜下出血をきたした椎骨動脈解離性脳動脈瘤を経験したので報告する.症例は57歳女性で, クロールで水泳中に右後頚部痛で発症した.保存的加療を行っていたが, 発症翌日にはWallenberg症候群を呈し, 脳血管撮影にて右後下小脳動脈(PICA)より末梢の椎骨動脈解離性脳動脈瘤と診断した.虚血発症であったため, 保存的に加療を行ったが, 経過中にクモ膜下出血を起こし, 最終的に開頭してPICA分岐部の遠位側でクリップによる閉塞を行った.術後の脳血管撮影では, 稚骨動脈頭蓋外部分(V3)から閉塞が認められた.後方視的な検討では, 発症時の脳血管撮影で頭蓋外での解離の起始が疑われた.本症例では, 発症機転をより重視して推骨動脈頭蓋外部分の病変を早期に発見するように努力すべきであったと反省させられた.
