However, there is a question whether the flame cell formula of 2〔(3+3+3+3+3)+(3+3+3+3+3)〕=60 is justified. Therefore, I question the possibility of the cercaria of P. mexicanus reported by Ito et al. in 1985. If it has a pseudo-sucker, it belongs to another species of Paragonimus cercaria. The cercaria reported by Tongu et al. in 1990 from Venezuela was eliminated the possibility of a new species. It is probable that this cercaria belongs to P. mexicanus. Ibanez revived the name of P. peruvianus in 1990 by the differences in the cercaria and adults. However, I disagree with his opinion.No potential conflict of interest relevant to this article was reported.岡山大学医学部保健学科Acta Medica Okayama1345-09481022000身体機能障害者の公共交通機関利用を妨げる要因8590ENMichiyoHigakiYoshikoAkazawaYasuyoOhtaToyokoAkazawaHisaeOhtaNobukoOhnoHiromiMiyakeHiroeIshiharaNorieMatsuuraKeikoAbeMikaAkagiTakeoOhtaHatsueOkano10.18926/11729機能訓練事業として実施している「生活リハビリ教室」の教室生208名を対象に，公共交通機関を利用して外出するために障害になっている要因を明らかにする目的で，郵送法による自記式アンケート調査を行った。回答は125名（60.1％）からあった。外出経験がある者は67名（53.6％）で外出経験がない者が58名であった。外出時に付添いが必要と思っている者は，外出経験のない者に多かった。公共交通機関を利用しての外出を阻害している要因には，乗り物の昇降口に段差があることや早く発車して危険である，また周囲の人に介助を依頼しにくいことなどが挙げられている。身体機能障害者が外出できない理由は個人によって異なってはいるが，地域社会に身体機能障害者を受け入れる環境を整えていく必要がある。No potential conflict of interest relevant to this article was reported.岡山大学医学部保健学科Acta Medica Okayama1345-09481022000Modelling of interface construction relating to power-line interference phenomenon in biopotential signal measurement system107115ENYoshitakeYamamotoTakaoNakamura10.18926/11726A modelling of interface construction relating to power-line interference phenomenon was described. Source of interference was displacement currents which flowed from AC power-line configuration (APC) to a model. The interference depends on some factors: distance between the APC and a model ; length of unshielded leads ; position of the APC in vertical or horizontal direction ; and skin-electrode impedances which were balance or unbalanced. The position of APC and skin-electrode impedances were important in contributing of the interference. The interference was still large even though skin-electrode impedances were balance. This was caused by the disagreement in two displacement currents. It was overcame by adjustment of APC in vertical direction. As a result, total interference would be very small or zero. The result shows that interference in ECG signal recording can be eliminated to about 10 μV. Although interference of power-lines is a complicated phenomenon, the problem is easier to understand by using this modelling.No potential conflict of interest relevant to this article was reported.岡山大学医学部保健学科Acta Medica Okayama1345-09481022000マンモグラフィ用増感紙／フィルムシステムの特性曲線における空気減弱の影響9198ENToshinoriMaruyamaSachikoGotoYoshiharuAzumaYoshitadaNakagiriKoichiShibuyaKatsuhikoSugita10.18926/11721マンモグラフィ専用装置を使用して，距離法で低エネルギー領域のX線におけるマンモグラフィ用増感紙／フィルムシステムの特性曲線を得るためには，空気滅弱の影響を考慮する必要がある。その影響について，実効エネルギーから空気減弱分を補正，照射線量測定による補正，Bednarek法を応用した新距離法の3種類の方法を使って検討した。さらに，一般撮影装置でも，マンモ用システムに対して距離法で特性曲線を作成し，エネルギ
ーの変化による影響についても検討した。その結果，3方法の特性曲線およびグラディエント曲線は，新距離法が高濃度域でわずかにずれるもののほぼ一致した。新距離法に対する平均階調度，最大階調度の最大誤差は，2.7％，0.2％であり，一般撮影用装置の距離法と3方法との間では，一般撮影用装置の距離法に対して最大誤差は2.7％，1.5％であった。以上のことから，エネルギーの変化による特性曲線への影響はほとんどなく，低エネルギー領域での特性曲線は空気特配の補正を行うことのみで得られると考えられる。No potential conflict of interest relevant to this article was reported.岡山大学医学部保健学科Acta Medica Okayama1345-09481022000An analysis of structural relationship among the components of quality of life of kidney transplant recipients by using a causal model7784ENYukoHayashiNaomiKanaoYoshikoNakanishiKumiWatanabeEikoHoshina10.18926/11717The purpose of this study is to analyze the structural relationship among the components of quality of life of kidney transplant recipients by using a causal model. The subjects were 329 recipients who had regular checks-up following transplantation in seven general hospitals in Tokyo, Gunma, Aichi, Okayama, and Hiroshima, and agreed to participate in this study. Ferrans and Powers's Quality of Life - Index Kidney Transplant version was used to measure perceived quality of life. The self-administered questionnaires were handed over to the subjects, who completed the instrument on the spot. After that, the answers were collected immediately. The factor analysis and the covariance structure analysis were used to make clear the structural relationship among the components of quality of life. The results of data analysis were as follows : (1) Five components of quality of life were extracted ; socio-economic functioning, family ties, emotional support, physical health, and peace & happiness. (2) The scores in the family ties dimension and the physical health dimension were higher than in the others, and the score in the socio-economic functioning
dimension was the lowest. (3) The physical health showed the starting point in a causal model. (4) The physical health influenced the family ties and the socio-economic
functioning. (5) The socio-economic functioning strongly influenced the peace & happiness and the emotional support. (6) The family ties influenced the socio-economic functioning, the emotional support, and the peace & happiness. Therefore, it was conceivable that it was particularly important to make approaches for the physical health, the family ties, and the socio-economic functioning dimensions to improve quality of life.No potential conflict of interest relevant to this article was reported.岡山大学医学部保健学科Acta Medica Okayama1345-09481022000ラットにおけるカイニン酸けいれん発作重積後のMRI所見と病理所見の関係6976ENJunkoSakiyamaMotoiOkamotoYoshihiroKitamuraNorihitoYamada10.18926/11715側頭葉てんかんでは，てんかん焦点に一致してMRI T2高信号領域が見られ，FLAIR法でこれがより明瞭になるが，このMRI所見と病理組織学的変化との関係は必ずしもはっきりしていない。そこで，Sprague－Dawleyラットにカイニン酸（KA）でけいれん発作重積状態を起こし，経時的にMRIを記録するとともに，ニッスル染色，GFAP免疫染色での病理組織学的変化を調べて両者の関係について検討した。KA群では，MRIで1～8週間後のいずれにおいてもpiriform cortexからentorhinal cortexにかけて不整形のT2高信号領域がみられたが，stage3のけいれん発作しか出現しなかったラットではstage4，5が出現したラットに比べて程度が弱かった。組織学的には，CA1，subiculum，piriform cortex，entorhinal cortexで神経細胞の消失，濃染細胞の増加と萎縮，GFAP免疫反応の増強が見られたが，piriform cortex，entorhinal cortexでの神経細胞消失の程度はT2信
号の程度と相関せず，GFAP免疫反応が増強した領域に一致して高信号がみられた。しかし，海馬のGFAP免疫反応増強はMRI所見に反映されず，これはMRIの解像度の限界にもよると考えられた。No potential conflict of interest relevant to this article was reported.岡山大学医学部保健学科Acta Medica Okayama1345-09481022000Breast dosimetry system in screen/film mammography99106ENSachikoGotoYoshiharuAzumaToshinoriMaruyamaYoshitadaNakagiriYoshihiroTakedaKatsuhikoSugitaShigefumiKadohisa10.18926/11714The average glandular dose to glandular tissue m mammography is generally assumed to be a function of beam quality (HVL), x-ray tube target material, tube voltage, breast thickness, breast composition and, to a lesser extent, x-ray tube voltage waveform. The average glandular dose is generally determined from published tables with knowledge of the above function. Tables for a high frequency x-ray generator are not yet published. In our study, the lookup tables for the average glandular dose were made at 28 kV (high frequency x-ray generator), employing a breast simulating tissue (0-100% adipose tissue, 0-100% glandular tissue) phantom for an Mo target - Mo filter source assembly. We tried to estimate breast composition from x-ray mammograms by digital image processing techniques, also using the simulating tissue phantom. Then the system that automatically calculates the average glandular dose from digitized clinical x-ray mammograms was built. It is considered that this system can contribute to objective evaluation of the average
glandular dose.No potential conflict of interest relevant to this article was reported.岡山大学医学部保健学科Acta Medica Okayama1345-09481022000岡山大学医学部保健学科看護学専攻設置に向けての看護学教育への取り組みとその経緯123133ENYukoHayashiToshikoIkedaKumikoKatoNiwaOta10.18926/11712No potential conflict of interest relevant to this article was reported.岡山大学医学部保健学科Acta Medica Okayama1345-09481022000看護学生が体験から得た食習慣の改善に関する理解117122ENNiwaOhtaYukoHayashiTakeoOhtaEikoHoshinaMiwakoNarusaka10.18926/11710看護学生が自己の体験を通じて得た食習慣の改善や患者教育に関する考えを明らかにした。短大看護学科2年生84人を対象に自記式アンケート調査を行い，19歳～21歳の学生73名について分析を行った。栄養学の学習を終えた学生に通常の1日分の栄養摂取量を計算させ，それをもとにそれぞれの食習慣改善計画を立てさせ実行させた。1ヵ月後，再度摂取量の計算をさせて，前回の結果との比較の上で，自分の体験の評価をさせた。その結果，学生が主に考えたことは以下の3点に集約された。①食品の求めやすさや調理の方法の簡単さが食習慣の改善には重要である。②食習慣の改善が困難となるのは，知識の不足や意志の持続性と関連することである。③食習慣の改善の動機づけになるのは，そのことの意義を知ったり，自分の栄養摂取量を点検することである。学生は，食習慣の改善の困難さや容易さおよび患者の栄養指導における留意点について理解していた。No potential conflict of interest relevant to this article was reported.岡山大学医学部保健学科Acta Medica Okayama1345-09481022000教育研究業績目録 1998.4～1998.12134ENNo potential conflict of interest relevant to this article was reported.
