The effect of experimental hyperlipemia on insulin sensitivity was evaluated in seven healthy cats. Serum triglyceride and free fatty acid concentrations were significantly (P<0.05) higher when lipid-heparin was administered (2,894 ± 1,526 mg/dl and 4.54 ± 0.70 mEq/l, respectively) than when saline was administered (70 ± 42 mg/dl and 0.22 ± 0.08 mEq/l, respectively). A glucose clamp test revealed that the mean glucose infusion rate when lipid-heparin was administered (5.80 ± 0.67 mg/kg/min) was significantly (P<0.05) lower than when saline was administered (8.52 ± 1.83 mg/kg/min). These results suggest that experimental hyperlipemia induced insulin resistance in the healthy cats.

Porphyromonas gulae, a gram-negative black-pigmented anaerobe, is a pathogen for periodontitis in dogs. An approximately 41-kDa fimbrial subunit protein (FimA) encoded by fimA is regarded as associated with periodontitis. In the present study, the fimA genes of 17 P. gulae strains were sequenced, and classified into two major types. The generation of phylogenetic trees based on the deduced amino acid sequence of FimA of P. gulae strains along with sequences from several strains of Porphyromonas gingivalis, a major cause of human periodontitis, revealed that the two types of FimA (types A and B) of P. gulae were similar to type I FimA and types II and III FimA of P. gingivalis, respectively. A PCR system for classification was established based on differences in the nucleotide sequences of the fimA genes. Analysis of 115 P. gulae-positive oral swab specimens from dogs revealed that 42.6, 22.6, and 26.1% of them contained type A, type B, and both type A and B fimA genes, respectively. Experiments with a mouse abscess model demonstrated that the strains with type B fimA caused significantly greater systemic inflammation than those with type A. These results suggest that the FimA proteins of P. gulae are diverse with two major types and that strains with type B fimA could be more virulent.

To evaluate the relationship among immune status and increased morbidity and mortality, peripheral blood lymphocytes (CD3+, CD4+, CD8+, CD21+ cells) from 32 healthy dogs aged over 8 years were analyzed. Twenty-five dogs out of 32 were followed-up for 3 years after the analysis, and 14 dogs were found to be diseased and nine dogs died. There was no notable difference between the age of dogs that died compared with the ones that survived. The relative percentage of CD4+ and CD4+:CD8+ ratio decreased notably in dogs falling ill compared with healthy dogs. The relative percentage of CD3+ lymphocytes showed a notable decrease in dogs that died within 3 years in comparison with dogs that survived. In a discriminant analysis of morbidity and mortality, most patients were correctly classified as diseased or not and surving or dead, respectively. These results indicate that the immunophenotypes of peripheral blood lymphocytes in older dogs offer promise as parameters for evaluating mortality and morbidity.

テレビ会議システムなどの普及により,場所や時間的な制約に関係なく意思決定の場を設けることが可能となってきている.その一方で,意思決定を活発化,円滑化するための場の設計方法については見落としがちである.本稿では,意思決定の場におけるコミュニケーション支援のためのメカニズムデザインを経済学的,心理学的観点を踏まえて行い,その場の設計が意思決定の場におけるコミュニケーションに与える影響について考察する.

琵琶湖産アユとワカサギをカワウの胃内容物から種判別できるようにする目的で尾鰭骨格の観察を行った。両種は尾部棒状骨に下尾骨が癒合せず,2-5個の尾鰭椎前椎体に神経棘が関節することから他の琵琶湖に生息する魚類と区別できた。またアユは尾鰭椎前第3および第4椎体の神経棘が筒状の構造を持ち,先端に軟骨を有すること,そして上尾骨が2本で後方の下端が2叉するか,もしくは3本であることにより,ワカサギと明瞭に識別することが出来た。また両種の尾鰭骨格と体長の関係式も求めた。

国内・国外に所蔵される銃砲に関する文献史料(炮術秘伝書)および実物資料(銃砲)の調査を行い、16世紀なかば鉄炮伝来から19世紀末の明治初年までの日本銃砲史が5期に区分できることを示し、またその技術的変遷を明らかにした。鉄炮銃身に使用されている素材である軟鉄を作るための精錬方法である大鍛冶はすでに技術伝承が途絶えていたが、文献記録にある各工程の意味を明らかにし、その再現に成功した。

The heteropterous fauna of the Izu Peninsula protruding onto the Pacific from central Honshu, Japan, has been rather poorly known up to the present. In this paper, 132 heteropterous species, including 49 previously recorded, belonging to 31 families are listed. Though the faunal research is not sufficient yet, a brief zoogeographic discussion is made on the basis of these data. These 132 species, except for two undetermined ones, are classified into the following five groups according to the difference in their distributional patterns. Group 1 in cludes 27 species, whose ranges are limited within the Oriental Region and Japan, such as Macroscytus subaeneus, Eysarcoris ventralis, Eucorysses grandis, Scotinophara lurida, Cletus punctiger, Physopelta cincticollis, Schidium marcidum, Sirthenea flavipes, Microvelia douglasi and so on. Of these, Eucorysses grandis is the only species whose habitat seems to be closely associated with laurel forests. Most of the other species, excepting predacious ones, are very common in Japan and are more or less injurious to such cultivated crops as rice, beans and citrus. They appear to have secured their superior position in the heteropterous fauna of Japan according to the expansion of acreage under cultivation by continuous human activities. Group 2 contains 52 species distributed within the southern area of the Palaearctic Region extending from China to Japan, such as Megacopta punctatissima, Megymenum gracilicorne, Gonopsis affinis, Halyomorpha mista, Poecilocoris lewisi, Anaxandra gigantea, Urostylis westwoodi, Colpura lativentris, Anacanthocoris striicornis, Plinachtus bicoloripes, Piocoris varius, Acanthaspis cincticrus, Rhinocoris ornatus, Velinus nodipes, Hydrometra albolineata, Metrocoris histrio, Notonecta triguttata, Laccotrephes japonensis, Diplonychus japonicus and so on. Though they occur in various vegetation growing on every altitude from lowlands to the beech zone, none of them seem closely connected with laurel forests. Group 3 consists of 25 species, whose distribution is bounded within the northern part of the Palaearctic Region covering Northern Europe, Siberia, Amurland, Sakhalin and Japan, e. g., Arma custos, Carbula humerigera, Lelia decempunctata, Graphosoma rubrolineatum, Acanthosoma forficula, A. denticauda, Elasmucha putoni, Homoeocerus dilatatus, Galeatus spinifrons, Gorpis brevilineatus, Phytocoris nowickyi, Apolygus hilaris, Saldula soctica, Sigara substriata and so on. Many of them, for example Lelia decempunctata, Acanthosoma spp. and Elasmucha spp., mainly inhabit beech forests. This group seems predominant in the heteropterous fauna of the cold-temperate deciduous broadleaved forests of Japan. Group 4 comprises 23 species endemic to Japan, such as Pylorgus colon, Dimorphopterus japonicus, Geocoris proteus, Metochus abbreviatus, Aradus orientalis, Acalypta miyamnotoi, A. tsurugisana, Anthocoris miyamotoi, Onomaus lautus, Speovelia maritima, Aphelocheirus vittatus and so on. Group 5 includes 3 species, Piezodorus hybneri, Liorhyssus hyalinus and Cimex lectularis, which are either cosmopolitan or widespread. Some faunal characteristics of the Izu Peninsula are pointed out mainly based upon the pentatomoid species belonging to the first three groups in comparison with those of such areas as the Tsushima Islands (MIYAMOTO, 1970), the Kii Peninsula (TOMOKUNI, 1979), Saitama Prefecture (NOZAWA, 1978) and Niigata Prefecture (HASEGAWA, 1960) (Table 1) : A. Species of Group 1,probably the Oriental elements, are not more abundant in the Izu Peninsula than in the other areas, though they are much fewer in Niigata Prefecture. B. Species of Group 2,probably the southern Palaearctic elements, show higher percentage in the Tsushima Islands and the Izu Peninsula than in Saitama and Niigata Prefectures. On the contrary, the percentage of Group 3 species, probably the northern Palaeractic elements, is lower in the Tsushima Islands and the Izu Peninsula than in Saitama and Niigata

1. クエン酸リアーゼを用いた酵素法による測定で正常健康人109例,及びカルシウム結石患者231例の尿中クエン酸排泄量について検討し以下のような結果が得られた. 1)健康人男子72例,および女子37例の尿中クエン酸排泄量は383.9±156.5mg/day,および452.6±171.4mg/dayであり,女子の方が5%の危険率で有意に高値を示した.また,カルシウム結石群では男子326.2±203.6mg/day,女子374.2±219.7mg/dayであり,男子は5%の危険率で低値を示し,女子は結石再発群のみが有意な低値を示した. 2)健康人の男女の排泄量の統計学的検討により,クエン酸排泄量の正常下限値を男子200mg/day,女子250mg/dayとして低クエン酸尿症を定義したところ,結石群では男女とも約30%の低クエン酸尿症が認められた. 3)過カルシウム尿症あるいは過蓚酸尿症と低クエン酸尿症の合併は,いずれも結石群の10%前後に過ぎなかった. 4)尿中クエン酸排泄量と尿量,尿中マグネシウム,尿酸,リンおよび蓚酸排泄量の間には弱い正の相関を示す傾向が認められた. 2. カルシウム結石患者に対し,クエン酸剤を1日3gを経口投与し,尿中パラメーターの追跡検討を行ったところ尿pHと尿中クエン酸排泄量の有意な上昇の持続が観察された.また6ヵ月以上の投与症例での検討では結石再発防止効果が予想される結果が得られた.
