The amphidromous sleeper Eleotris oxycephala (Perciformes: Eleotridae) is mainly distributed along the Kuroshio Current in East Asia, and this current is thought to be the main driver of the species' dispersal. Due to anthropogenic environmental changes in rivers, E. oxycephala is ranked as a threatened or near-threatened species in the red lists of 12 prefectures in Japan. Moreover, there is concern that the species' dispersal pattern could be changed due to fluctuations in the Kuroshio Current caused by global warming. In this study, 40 microsatellite markers were developed for E. oxycephala, and their suitability was tested on 43 individuals from two populations of E. oxycephala from Kanagawa and Miyazaki Prefectures. The number of alleles, expected heterozygosity and fixation index at each locus were 2–10 (mean = 5.350), 0.034–0.860 (mean = 0.650) and -0.261–0.448 (mean = 0.065), respectively. Furthermore, there was a lack of genetic difference between the two populations (FST = 0.008, F'ST = 0.024), indicating widespread gene flow via the Kuroshio Current. These markers will be useful to evaluate the genetic structure and infer population demographic history of E. oxycephala populations, which may assist in the conservation of this species.

A 52-year-old man who had been taking omeprazole, a proton pump inhibitor (PPI), for 25 years developed iron deficiency anemia. An evaluation of the entire gastrointestinal tract did not reveal any possible causes of gastrointestinal blood loss. The cause of the iron deficiency was considered to be a reduction in gastrointestinal iron absorption in association with the reduced secretion of gastric acid due to PPI use. This case demonstrates that long-term PPI use for as long as 25 years may cause iron deficiency anemia and should be considered in the differential diagnosis of iron deficiency anemia in long-term PPI users.

「神の国」をはじめ一連の発言で首相としての資質を問われた森首相に対する評価は2000年総選挙での有権者の投票行動に影響していたのか。本稿の目的は,2000年総選挙を題材に,従来あまり注目されることのなかった党首評価と投票行動の関連を明らかにし,日本の投票行動研究に新たな理論的貢献を試みることにあった。分析の結果明らかになったことは,次の3点である。第1に,投票行動に党首評価は影響を与えており,しかもその影響は小選挙区よりも比例区に顕著に見られた。第2に,党首評価は小選挙区•比例区の2票の使い方,いわゆる分割投票にも影響を与えていた。そして第3に,森首相に対する評価には内閣業績評価,「神の国」「国体」など一連の発言に対する評価,自公保という連立の枠組に対する評価が影響を与えており,中でも発言に対する評価の影響が最も大きかった。
