| 抄録 | The delivery assistance laboratory is one of the most important part of the professional curriculum in the training program for midwives. The educational significance of 10 cases of delivery assistance was reviewed. The technical standards of the students improved with accumulation of experience in the assistance of deliveries. Evaluation of the methods in which the students were assessed with regard to technical improvement in delivery assistance was performed. Of the total number of 136 students of midwifery registered at our school in the past 7years, 50 who were able to assist successively in 3-10 cases of normal childbirth were evaluated in this study with regard to their acquisition of skills needed to assist in deliveries. Fourteen technical items related to the assistance of delivery in its second and third stages were assessed. An evaluation standard consisting of 3 grades, namely "able to perform", "somehow able to perform", and "not able to perform" regarding the above mentioned 14 technical items were used to assess the mastery of delivery assistance techniques by the students. Our results showed that as the students accumulated experience in delivery assistance, self-assessment ratings of "able to perform" increased on the average. The accumulation of skill concerning the management of the neonate immediately after birth, the instruction of patients regarding the application of abdominal pressure, and the assistance during crowning was specially evident. In contrast, although self-assessment ratings of "able to perform" with regard to "assistance of the mother immediately after giving birth" and "assistance immediately after the delivery of the fetal head" did increase, its rate of increase was small. |

| タイトル（別表記） | Ferrous Iron-induced Lipid Peroxidation in Cell Culture: preliminary experiments |

| 著者 | 山本 剛禧| |
| 抄録 | To study the effect of Fe(2+) on the cell culture, preliminary experiments related to the lipid peroxidations of 3T3 cells and calf serum were carried out. Amonuts of lipid peroxides, as thiobarbituric acid (TBA)-reactive substances, were measured by means of the TBA color reaction under the acidic conditions by acetic acid, and were expressed as TBA value. The TBA value of calf serum in the phosphate buffered saline (PBS) with ethyrendiaminetetraacetate (EDTA) was lower than that of the control. The value in the presence of Fe(2+) showed significantly high level, but it was almost prevented by the addition of EDTA. Besides, Fe(2+)-induced lipid peroxides of serum in the PBS during the incubation at 37℃ were capable to measure by the application of EDTA. The TBA values of trichloroacetic acid (TCA) precipitates isolated from serum in the PBS and the culture medium were lower than that of control serum, but no difference was observed between the both TCA precipitates. The results suggested that the impurities in the culture medium were removed by TCA precipitation. Effects of Fe(2+) and EDTA on the TBA value of TCA precipitates were observed similarly to the case of control serum. Fe(2+)-induced lipid peroxidation of the cells in the PBS, which the peroxidation was stopped by the addition of EDTA, was observed, and it was accompanied with the lag time of induction period. The TBA value of the cells was more prevented by EDTA. The method in this paper may not be capable for the quantitative measurements of lipid peroxides in cells or serum, but is applicapable to measure the changes of relative amounts of lipid peroxides. |

| 抄録 | Relationship between ethanol drinking and organs injury was reviewed and special emphasis was put on alcoholic liver disease. Consumption of alcoholic beverage expressed as ethanol per capita of adult in Japan increased 2.1 times in these 25 years and it is still increasing. Although the incidence of alcoholic liver disease in Japan also increased greatly during the above period, it seems likely that plateau level is coming because of genetically defined, unique type of alcohol metabolism in Japanese. Sex differences in susceptibility to alcohol were discussed. Among the six types of alcoholic liver disease, alcoholic liver fibrosis is relatively frequent in Japan. Mechanism of liver injury has been studied extensively. Alcohol itself is toxic but other factors such as dietary fat are also important. Biochemical and immunological markers of drinking were presented. As for the treatment, most patients especially in early stages of the disease well respond to alcohol withdrawal, but therapy of alcohol dependence in the background of the disease is very difficult requiring cooperative works of different kinds of specialists. |

| 抄録 | アイデンティティの確立していない子供をもつ壮年期女性の乳癌発病後の役割意識の変化を、病者役割の受け入れと母親役割意識に焦点を当てて、質的帰納的に分析した。役割意識の変化は、母親役割意識と病者役割意識の関係から6群に分類され、母親役割意識内容に特徴があり、群によって乳癌のもたらす意味が異なった。乳癌のもたらす意味は、母親役割葛藤群では母親としての自己を脅かすもの、母親役割拡大群では母親役割維持のために克服するもの、母親役割目覚め群では母親役割の中に取り込み共存するもの、母親役割成長群では母親としての成長を促すチャンスとなるもの、自己改革群では自己自身の生き方を問うもの、変化なし群では簡単に乗り越えられるものであった。また病者役割の受け入れに葛藤を有する母親役割意識は、葛藤の特徴から、母親役割の強要による葛藤、代替不可能な母親役割の脅かしによる葛藤、乳房喪失による葛藤、子供への悪影響による葛藤、死を自覚した母親役割の葛藤の5つの葛藤を有する母親役割意識に分類された。以上から、子供を持つ乳癌患者に対する看護のあり方は、1）病状を正しく認識するための援助、2）患者の役割意識を考慮した援助、3）外来通院時の積極的働きかけの3点を重視する必要がある。 |

| 抄録 | With the 17-th century an essentially new period in the development of mathematics began. The circle of quantitative relations and spatial forms of mathematics studied now was no longer exhausted by numbers, quantities and geometric figures. On this basis there resulted the explicit introduction into mathematics of the ideas of motions and change. Being inseparably connected with the needs of natural science, the accumulation of quantitaive relations and spacial forms studied in mathematics was continuously expanding. However, in addition to this quantitative grouth, at the end of the 18-th and the beginning of the 19-th centuries a number of essentially new features were observed in the development of mathematics. The enormous amount of factual material which had been accumulated in the 17-th and 18-th centuries led to the demand for a deep logical analysis and unification of it from a new point of view. In essence, the relationship between mathematics and natural science was no loss close but was now increased in complexity. The majority of new theories arose from internal requirements of mathematics itself. However, the circle of applications to problems of science and technology was greately expanding at this time. In this way, as a result of both the internal requirements of mathematics and the new needs of science and technology, the circle of quantitative relations and spatial forms studied in mathematics was greately expanded: relations between elements of arbitrary groups, operations in function spaces, etc. are now parts of mathematics. In this paper, we are concerned with mathematical thought. Several ideas of great scientists are introduced, and we know the essence of mathematical thought. The power of mathematical thought can be brought up by means of a deep thought. The relationship between mathematical thought and creativity is also studied. |

| 抄録 | Role playing of patient-nurse relationship done by nursing student in order to practise communication skills. All the lines spoken by students playing as nurses in seventy-three scenes were analysed and classified by Snyder's categories. The results obtaind were as follows; 1) Average time required to for one scene was 6 minutes 35 seconds, and the speechs by the students average 21.5 time for this time. 2) Lead taking categorise occupied 51.9% of total linse spoken, directive counseling categorise 19.5% and non directive responce to feeling categories 17.4%. Seventy-nine% of lead taking categories were specific type question. 3) When speechs between a patient and nurse progressed well, technique of restatement of content or problem was frequently used, compared to poorly progressed spech. 4) It was concluded that the role playing method is effective for students' learning communication skills. |

| 抄録 | The shortage of nurses is one of the very important social problems in Japan. This study by questionaire survey was done to reveal the factors affecting the decision making of senior highschool students to enter nursing course. Two handred thirty-four 3-year college students studying in nursing course their 168 parents and 109 highschool teachers responded, and those data were statistically analysed. The results were as follows; 1. Students' choice to the nursing course were done basically by themselves, but were influenced by their parents and highschool teachers. 2. They, highschool students, parents and teachers have little knowledge about nursing job and nursing education on that time. 3. The incease in number of bachelor course to nursing in Japan may have impact on students, their parents and teachers, and it may link with the increase of students aiming to be nurses. |

| 抄録 | The Video-tape recorder was introduced to tape the scene of a preliminary test of students' practice to aseptically handle syringes. These video-tapes taken were released to students to watch and to refer back to for their self-study. Students were consequently divided into four groups on how to utilize the video-tapes. The scores of the preliminary and final test and their differences were statistically compared by the groups. The results suggested that the use of video-tapes is effective for the achievement of skills in delicate techniques of nursing care and especially the utilization upon their own initiative leads to a more successful result. |

| 抄録 | The purpose of this study was to obtain the basic data for the study of "Death education on nursing education". We investigated 235 students aged 18-21 in the school of allied health science O University (return rate 100%). The questionnare was composed of the questions about experience to be presented at the familiar person's last moment, experince to be attended at the funeral, intention to take their child to the funeral in the future, and knowledge of ritual behaviors for the dead. The results are as follows: 1) About 20% of students had experienced the dying hour familiar persons who were almost grandfather, grandmother, great-grandfather and great-grandmother. 2) Almost all students had attended at the funeral as the survivors. 3) About 2/3 students had intention to take their child to the funeral in the future to let them learn death. About 1/3 students had no intention to take their child to the funeral, or did not decide their intention yet. 4) Among ritual behaviors for the dead, students well recognized "Kiyome no sio" and "Kita makura" that were well known in the daily life, and "Hidarimae" and "Tatemusubi" that had learned in the lecture of nursing for the dead. Conversely, despite of learning "Yukan", few students knew it because they didn't conscious of it as the ritual behavior. The ritual behavior is important to alleviate the survivors' grief. Death education on nursing education must introduce Thanatology (interdisciplinary curriculum on death including ethnology, sociology etc.). |

| 抄録 | Dry-bulb and wet-bulb temperature in classrooms at the School were measured from April through July in 1990, by means of an Assmann ventilated psychrometer. The thermal sensation of the female students was surveyed by a questinnaire at the same time. Correlation coefficients between the rates of thermal sensation and thermal indicators such as natural temperature, relative humidity, effective temperature and discomfort index were computed. And multiple regressions equations of these indications and partial corelation coefficients were also computed from the temperature and humidity. These data showed that the students' thermal sensation in this season is primarily influenced by temperature and not so much by humidity. The relation between temperature and the rate of students who feel the heat was discussed. |

| 抄録 | The measurement of Rheumatoid Factor (RF) has been a valuable tool in diagnosing Rheumatoid Arthritis (RA) for many years. Since Waaler's discovery of the RF, many studies have been carried out. In the recent years studies have been shown that there is no such correlation between the level of the RF titers and disease activity. In this report we have measured the IgM-RF, IgA-RF and IgG-RF by an Enzyme linked immunosorbent assay (ELISA) for 144 normal human sera and 50 patients sera. At the same time we have measured the titers of gelatin particle agglutination (RAPA) and the Latex agglutination (RA-test). The value of IgG-RF have been most correlated to the titers of RAPA (r=0.9037). Using this ELISA technic to detect IgM-, IgA- and IgG-RF, have been aviable more clearly the activity and the stage of Rheumatoid disease. |

| 抄録 | Sensitive enzyme Immunoassay method specific for rabbit C-reactive protein was established. This was based upon specific Ca(2+)-dependent binding profile of C-reactive protein for some compounds containing phosphorylcholine moiety intramolecularly. By this method, more than 0.001μg of rabbit C-reactive protein was detectable. Specific binding of C-reactive protein for p-aminophenylphosphorylcholine immobilized on solid phase was inhibited by either addition of EDTA or phophorylcholine analogues, effectively. It may be useful to study possible roles of C-reactive protein in inflammatory regions. |

| タイトル（別表記） | The Neurophysiological Implications of an Atypical Slow Negative Potential in Short Interval CNV Paradigm |
| フルテキストURL | 001_091_097.pdf |
| 著者 | 岡本 基| 手蓑 正人| 中川 尚久| 森 宏和| |
| 抄録 | We recorded a slow negative potential from Cz (10/20 method) in 49 healthy students (12 male, 37 female, mean age 19.1) by a short interstumulus interval CNV paradigm. The interstimulus interval was 2 or 3 seconds, the warning stimulus presented at random or regular interval at 0.2 Hz. An atypical negative variation with two separated negative peaks was recorded in 26.0-30.6% trials regardless of interstimulus interval or modality of warning stimulus presentation, while a typical CNV was recorded in 32.0-59.2% of trials. No apparent negative variation was recorded in 14.3-18.4% in 2 seconds interstimulus interval, and 28-38% in 3 seconds interstimulus interval, showing that 2 seconds interval is better to get stable CNV recording than 3 seconds interval. The first negative wave of the atypical negative variation was 692-799msec in duration, but frequently prolonged to 1000msec or more in 3 seconds interval. It usually had negative peak around 900-1100msec, but sometimes around 1500msec. This features are different from any reported negative components of CNV. The second negative wave began 800-1200msec before second stimulus, and had its peak just before second stimulus, showing common features with readiness potential. The appearance of CNV was unsatble in the students in which the atypical negative variation was recorded in regular, 2 seconds intersitimulus interval, and the amplitude of slow vertex response and pattern reversal visual evoked potential was lower in thses students than in the students in which a typical CNV was recorded more than 3 times in total 4 times of trials. These findings indicate that the atypical variation observed in this study is due to a lowered arousal level or cortical neuronal activity, rather than a separated appearance of different components of CNV. |
