Background Acetabular dysplasia (AD) is a well-known cause of osteoarthritis (OA) of the hip, with its prevalence previously determined on plain radiography. The prevalence of preexisting AD was reported as 7.3% in a patient-based Asian population. Although computed tomography (CT) could evaluate AD in multiple planes, its prevalence using multiplanar CT images has not been reported. We investigated its prevalence with CT on coronal, axial, and sagittal planes and then determined if adding the axial and sagittal planes enhanced the investigation. Methods We retrospectively examined 52 consecutive Japanese individuals (mean age 59.4 years) who had undergone CT for conditions unrelated to hip disorders. The inclusion criteria of CT images were (1) reconstructed axial slice thickness of ≤1 mm and (2) normal pelvic rotations and tilt. Exclusion criteria were (1) age

This article reports the results of a study of knowledge creation systems in Japanese and American firms in Japan and the United States. The research was performed inside automotive and information appliance firms with primarily managerial employees from functional areas outside production. Through field interviews, a model was constructed of factors that drive successful knowledge creation, and a subsequent survey compared the use of these factors and their perceived utility among Japan-based and US-based respondents in these two knowledge-intensive industries. Our results show there is broad agreement regarding which practices help create knowledge, but they also suggest that Japan-based firms excel at implementing a distinctive, integrated system of organisational practices that promote organisational learning and stimulate knowledge creation.

ヒトのアトピー性皮膚炎（AD）では，経皮水分蒸散量（TEWL）の増加と共に，角質水分量の低下を認めることが知られている。セラミドは角質細胞間に分布する代表的な角質細胞間脂質であり，過剰なTEWLの増加を防ぐと共に，角質水分量を保持するはたらきをもつ。今回，慢性経過をたどるADの犬に対し，経口グリコシルセラミドを併用したところ皮膚症状の改善を認めた。以上より，経口グリコシルセラミドは犬ADの症例に対する補助食品として，選択肢の一つとなる可能性が示唆された。

犬毛包虫症（犬ニキビダニ症）の発症あるいは増悪において，宿主自身における先天性あるいは後天性の免疫機能の低下の関与が示唆されている。今回，難治性，再発性の全身性毛包虫症を呈した若例犬に対し，人で免疫賦活効果があると報告されているニゲロオリゴ糖を併用したところ皮膚症状の改善が認められた。以上の結果より，ニゲロオリゴ糖が犬毛包虫症の少なくとも一部の症例に対し，補助的な治療法として利用しうる可能性が示唆された。

As ferrets can suffer from a wide variety of cardiac disorders, indicators for detecting cardiac abnormalities on plain chest radiography are necessary. A total of 64 ferrets without heart disease underwent radiography in the right lateral (RL) and ventrodorsal positions (VD), and the lengths of the RL-sixth dorsal vertebra (6th DV), RL- and VD-long axis (LA) and RL- and VD-short axis (SA), RL- and VD- vertebral heart size, VD-length of the eighth costa (LEC) and VD-thoracic width at the eighth thoracic vertebra (8th TV) were measured to establish standard values of normal cardiac appearance. We evaluated statistical differences between genders and ferrets weighing < 1 kg and ≥ 1 kg for a total of 38 items. As a result, significant differences (P
