「国立大学附属学校における安全管理の在り方に関する調査研究会」は,学校の安全管理に関する状況や管理職・教員の危機意識などを探るために調査を実施した。その調査(平成14年)および今回の調査(平成16年)のうち,大阪府下の公立小学校を対象とした部分を分析した。附属池田小学校児童殺傷事件直後と今回の調査との比較,今回の調査から,管理職と教員との比較および学校規模による意識の違いについて検討した。その結果,多数の学校が不審者対応訓練を実践するようになったことと,名札の着用が定着したことが認められた。教員の校内巡視と心のケアのスキルアップが困難であること,大規模校では,校門の管理が困難であることなどが,未だ問題として有することが明らかになった。The group of researching of what should be prepared for improving the safety in Attached Schools to National Universities had tried to take a survey on the present situations of consciousness about safety in school and the management in the case of crisis in the relation to the staffs of the managerial post and other staffs of each schools. In this and last time the data which was obtained from above research is made use of further, mainly the data for the questionnaires from the municipal elementary schools is analyzed. In this time the data, the points of the analysis are the change of consciousness after the incident in Ikeda Elementary School attached to Osaka Kyoiku University, the comparison between two generation cohorts of staffs, the differences about with the sizes of schools. The results are following below. Many schools were practiced the training against the trespasser and/or the staffs and visitor were fixed put on the name card. The practice patrol inspect in school, parents and community in the case of emergent crisis and the improvement of skills of caring for mental health are not enough. The larger scale schools seems to have the more hardship about the limitation of the school gate.

昭和20年から現在に至るまでの性教育に関する書物を調査し,教育のなかで性教育はどのようにとりあげられ,位置づけされてきたかを検討した。その結果,性教育は,1)道徳面を重視した純潔教育の時代 2)純潔教育批判から生じた性の生理的側面が強調された教育の時代 3)生理的,心理的,社会的側面を含む人間としての総合的な教育の時代の三つの歴史的段階が認められた。また,学校教育のなかでの位置づけが不明瞭であることが教育現場での性教育の定着を妨げていることが示唆された。We investigated the literature on the sex education from 1945 to the present.And we studied that how the sex education was treated and where it was situated in the school education.In result we recognized the three historical phases in the sex education.1)The period of the education in sexual morality that the moral sense was attached importance to 2)The period of the physiological education that was emphasized against the education in sexual morality 3)The period of the comprehensive education that included physiological,psychological and social phases in human being Further,it was suggested that the sex education has not been situated in the school education clearly,which has prevented the sex education fixing int the spot of the education.

Male rats of Wister-strain,at 4 weeks of age were used at the start of this study.They were divided into two groups;namely,control and carbon tetrachloride(CCl_4).Rats of CCl_4 group were administered 50% CCl_4 from 5 to 13 weeks of age.The liver sampled and its ratio of lipids to liver weight and collagen content were examined by Forch's and Woessner's methods,respectively.Moreover,concentration of serum lipid and prolyl hydroxylase were examined.The ratio of lipids to liver weight in CCl_4 group reached 2.6 times against that of control group.Concentration of serum lipids,triglyceride and free fatty acid,showed significant difference between two groups.Collagen content of liver(μg/mg dry defatted liver±SD)was 2.28±0.47 and 3.27±0.48 in control and CCl_4 groups,respectively.Concentration of prolyl hydroxylase in serum(μg/ml±SD)was 0.61±0.13 and 2.11±0.23 in control and CCl_4 groups.The liver of CCl_4 group was falling into fatty liver and fibrosis.From these results,it was suggested that synthesis and secretion of collagen may be affected by the accumuration of neutral fat in liver cell.And we presumed that the increase of prolyl hydroxylase in serum is demonstrated the liver damage.Wister系雄ラットを4週齢からこの実験に用いた。それらは,対照群と四塩化炭素投与群(CCl_4群)との2群に分けた。CCl_4は,5から13週齢まで週2回四塩化炭素を投与した。CCl_4群は肝臓の脂質の割合とコラーゲン量および血清プロリルヒドロキシラーゼ量(PH量)が,対照群に比べ著しく増加することが示唆された。肝障害は,血清PH量を測定することで把握されることが示唆された。

dd系雄マウスを用い,運動が肝中および血中の脂質に及ぼす影響を継時的に検討した。運動群の肝中総Cho.量と遊離Cho.量は,15週齢で非運動群に比べ有意に増加した。血清中総Cho.濃度とHDL-Cho.濃度については,差は認められなかったが,リン脂濃度は,運動群が,加齢に伴い減少する傾向を示した。遊離脂肪酸濃度は,11週齢以降,運動群が有意に低値を示し,TG濃度は,9週齢以降,有意に低値を示し,約160mg/dlに抑制された。運動により,貯蔵脂肪の分解が亢進し,脂肪細胞の増加が抑制され,血中から肝への脂質の取り込みが亢進するとともに,肝から血中へのリポ蛋白の放出が抑制されることが示唆された。Male mice of dd-stain were used at this study.The trained group was exercise on a treadmill,and the untrained group used as control under normal laboratory condition.The liver and serum of the two groups were sampled from 4 to 15 weeks of age and their lipids were examined.The total-and free-cholesterol content in liver of the trained group increased more than that of untrained one at 15 weeks of age.No significant difference were observed in concentration of total-and HDL-cholesterol between two groups.Concentration of phospholipid showed a tendency to decrease with age in serum of trained group.Concentration of free fatty acid and triglyceride in serum of trained group decreased more than that of untrained one on and after 11 and 9 weeks of age,respectively.In trained group,concentration of triglyceride was controlled at 160 mg dl.This result suggested that exercise training controlled increase of adipose cell and release of lipoprotein from liver to serum.

Malgre son extreme importance,la biologie de l'eau chez les etres vivant ne semble pas attirer beaucoup l'attention des chercheurs.Cependant,certaines,recherches ont ete faites sur la teneur en eau des tissus animaux ou humain(2,4,5),en utilisant la methode qui consiste en un sechage et une pesee.Cette methode conventionnelle est longue et necessite de l'experience et de l'habilete pour etre suffisamment precise.Une methode pour mesurer la teneur en eau des globules rouges(3)et du cerveau(6)par chromatographie en phase gazeuse-liquide a ete mise au poiut.A partir de cette technique,nous avons propose une nouvelle methode qui permet de mesurer la teneur en eau du foie avec une plus grande precsion,une meilleure reproductibilite et un temps plus court que dans la methode conventionnelle.Notre methode a ete utilisee pour etudier les modifications de la teneur en eau du foie de la souris,selon l'age des animaux.ガスクロマトグラフによる肝臓の微量組織の水分含有量の迅速測定法を新しく開発し,成長期にあるマウスの肝臓の水分含自量の加齢による変動を観察した。

Male mice of dd-strain,at 3 weeks of age were used at the start of this experiment.They were divided into three groups;namely,standard solid food(SSF),choline deficient food Iand II(CDFIand CDFII),which were due to composition of food.Foods of CDF Iand II groups contained 12.5% and 8% vitamin free casein,respectively.The liver was sampled and its ratio of lipids to liver weights and collagen content were examined by Forch's and Woesnner's methods,respectively.The ratio of lipids to liver weights indicates that the liver of CDF I and II groups are falling into fatty liver.Hydroxyproline content of liver(mug mg get weights±SD)was 0.19±0.02,0.18±0.03 and 0.69±0.05 in SSF,CDF I and II groups,respectively.This result indicates that the liver of CDF II group are falling into fibrosis.It suggests that hepatic fibrosis is affected by the ratio of lipids.dd系雄マウスは,3週齢時からこの実験の初めに用いられた。それらは,3群,すなわち,餌の組成によって標準固型食群(SSF群),コリン欠乏食I群(CDFI群)とII群(CDFII群)に分けた。コリン欠乏食I群とII群の餌は,各々12.5%と8%のビタミンフリーカゼインを含んでいる。肝臓は,サンプルとされ,それらの肝重量に対する脂質の割合とコラーゲン量は,各々ForchとWoesnner法によって測定された。肝重量に対する脂質の割合は,CDF I群とII群との肝臓で脂肪肝になっていることを示す。肝臓のヒドロキシプロリン量(mug/mg wet weights±SD)は,SSF群,CDF I群とII群では,各々,0.19±0.02,0.18±0.03と0.69±0.05であった。この結果は,CDF II群の肝臓は,線維症になっていることを示す。肝線維症は,脂質の割合に影響されることを示唆する。

Male mice of dd-strain,at 3 weeks of age were used at the start of this work.They were divided into two groups;namely,standard solid food(SSF)and choline deficient food(CDF),which were due to composition of food.The liver in CDF group was falling into fatty liver.Total-and ester-cholesterol content of liver in CDF group showed the high value compared with those in SSF one.Free-cholesterol content did not show difference between two groups.Concentration of serum lipids in CDF group remarkable decreased compared with that in SSF one.This result suggests that the appearance of fatty liver is due to control the transfer of lipids from liver to blood.dd系雄マウスは,3週齢からこの実験に用いられた。それらは,標準固型食群(SSF群)とコリン欠乏食群(CDF群)との2群に分けられた。CDF群の肝臓は,脂肪肝になっていた。CDF群の肝臓では,総コレステロールとエステル型コレステロールは,SSF群に比べ高い値を示した。遊離のコレステロールは,両群に変化はなかった。CDF群の血清脂質濃度は,SSF群に比べ著しく減少した。この結果は,脂肪肝の出現は,肝から血液への脂質の移送の抑制によることを示唆している。
