In this study, we aimed to evaluate the longitudinal changes in the cranial shape of healthy Japanese infants using a three-dimensional scanner and construct a normal values database for the growth process. Preterm infants (gestational age < 37 weeks), infants with neonatal asphyxia (5-minute Apgar score of <7), and patients who started helmet therapy for deformational plagiocephaly were excluded from this study. The first scan was performed at approximately 1 month of age, followed by two scans conducted at 3 and 6 months of age. The parameters considered were as follows: cranial length, width, height, circumference, volume, cranial vault asymmetry index, and cephalic index. A cranial vault asymmetry index >5% was defined as deformational plagiocephaly. Changes in each parameter were examined using repeated-measures analysis of variance classified by sex and deformational plagiocephaly status. The rate of increase in each parameter was also examined. In total, 88 infants (45 boys and 43 girls) were included in this study. All growth-related parameters were noted to increase linearly with time. Sex differences were observed in all parameters except cranial length. Deformational plagiocephaly was found to have no effect on growth-related parameters. Cranial volume increased by 60% from 1 to 6 months of age. The growth almost uniformly influenced the rate of increase in volume in each coordinate axis direction. Overall, the mean trends in three-dimensional parameters in infants up to 6 months of age were obtained using a three-dimensional scanner. These trends could be used as a guide by medical professionals involved in cranioplasty.

「冬眠」現象を研究する魅力は、5℃以下まで体温を低下させることができる低体温耐性と、そのような極限の体温低下にも関わらず、細胞や組織レベルで異常をきたさず、生体が正常に機能を果たしている点にある。チョウセンシマリスから発見された新規の冬眠特異的タンパク質(Hibernation-specific proteins: HP)に関する研究は、現象の把握に終始してきた冬眠研究を、統合的な生理的調節システムとして理解する道筋を提供した。その結果、チョウセンシマリスでは冬眠を制御する年周リズムが体内で自律的に働き、それが血中のHP量を調節することで、冬眠可能な生理状態を自ら作り出していることが明らかとなった。また、HPの生体内調節の知見に基づき、冬眠期における脳内HPの機能をHP抗体の脳室内投与により阻害したところ、冬眠状態から覚醒状態への速やかな移行が見られ、冬眠の人工的制御が可能であることを証明した。本総説では、これまでに明らかとなっている冬眠調節に関わる生理機構の全貌に加え、冬眠調節の一端を担うことが明らかとなったHPを分子指標として用い、冬眠の進化あるいは地球規模の環境変化による冬眠動物への影響評価といった生態学的・進化学的視点に立った課題の解決に向けた最近の取り組みを紹介する。

Soybean-derived phosphatidylserine (Soy-PS) is a phosphatidylserine made from soybean lecithin by enzymatic reaction with L-serine. A double-blind, randomized controlled study was conducted to investigate the effects of Soy-PS on the cognitive functions of the elderly Japanese subjects with memory complaints. Seventy-eight elderly people with mild cognitive impairment (50–69 years old) were randomly allocated to take Soy-PS (100 mg, 300 mg/day) or placebo for 6 months. As a result, there was no difference in blood markers and vital signs during Soy-PS treatment and any side effect caused by Soy-PS treatment was not observed. Neuropsychological test scores were similarly increased in all groups including placebo group. However, in the subjects with relatively low score at baseline, the memory scores in PS treated groups were significantly increased against the baseline, while those of placebo group remained unchanged. And the memory improvements in Soy-PS-treated groups were mostly attributed to the increase in delayed verbal recall, a memory ability attenuated in the earliest stage of dementia. In conclusion, Soy-PS used in this study is considered as safety food ingredient and 6 months of Soy-PS supplementation could improve the memory functions of the elderly with memory complaints.

This article investigates the organization of the leading division of the board of education and the personnel and the duties of educational administrative staff members of the bureau of the board of education. This paper focuses on the case of Kyoto city which arranges experts on educational administration. My intention was to acquire new knowledge about the administrative staff members who have expertise in educational administration. The findings of this paper are follows. First, I confirmed the number of the general administrative staff members and educational administrative staff members, post arrangement, field of the duties from a point of view of making the arrangement of administrative staff members in the leading division of educational administration clear. I compared Kyoto city with an ordinance-designated city of the same scale as Kyoto city and three prefectures. Educational administrative staff members are appointed to the leading division in the cities other than Kyoto city and general administrative staff members are appointed to a limited division as general affairs manager. However, in Kyoto city personnel arrangement keeps trade with educational administrative members and general administrative staff members. This investigation revealed that general administrative staff members are in charge of various kinds of duties such as projects and administration of educational reform.Second, I carried out an investigation by interviewing general administrative staff members of the board of education in Kyoto city who are appointed to the leading division. I found that establishing a relationship between general administrative staff members and educational administrative staff members is the key to confirming how the duties are actually accomplished. I proposed “expert on educational administration” as a new concept of the field of the duties. The advantage of having experts on educational administration is that they are enrolled in the bureau of the board of education for a long time and acquire expertise in educational administration whereas educational supervisors return to school. The difference between these positions has an enormous influence on the way of accomplishing the duties. I pointed out that experts on educational administration in Kyoto city coordinate the conflict between the sort of jobs of experts on educational administration and educational administrative staff members and come up with an idea of politics and a role of expert on educational administration to show that the innovative leadership is the driving force of educational reform in Kyoto city.Last, I focus on general administrative staff members who are assigned to the board of education from the department of the head of the local government and the post and the field of the duties of experts on educational administration. An aim for further research is to acquire knowledge of the future personnel policy of educational administrative staff members.

Effect of nicotinic acid on the formation of catecholamine has been studied. Norepinephrine and dopamine concentrations in brain were 30 per cent higher and brain catecholamine formation was 50 per cent higher in the nicotinic acid-supplemented rats than the nicotinic acid-deficient rats. However, these catecholamine levels of the nicotinic acid-deficient rats were recovered by the administration of nicotinic acid. The concentration of brain tyrosine was unaltered after administration of nicotinic acid to the nicotinic acid-deficient rats. Therefore, the changes catecholamine formation by the nicotinic acid supplementation were not due to the difference of tyrosine concentration in the brain which is the precursor for catecholamine biosynthesis. As the difference of catecholamine concentration between the nicotinic acid deficient and the nicotinic acid supplemented group was smaller than that of catecholamine formation of these groups, the turnover of catecholamine was supposed to be decreased in nicotinic acid deficiency.

This paper investigates how discourse as an analytical framework can be constructed in the development of Michel Foucault's analyses. By doing so, the paper argues that multiple frameworks exist in analysis using the discourse. Moreover, the paper shows that the analytical method used and the character of the discourse in question rely on the researcher's understanding of the mechanism of society, as well as on his attempt to strategize discourse as an analysis framework to better understand social phenomenon.Given these points, a discourse should be understood in relation to the object of analysis. Therefore, the methodological concern should shift from explaining the nature of discourse analysis to assessing the analytical feasibility of the discourse.

本年度の研究実施計画に基づき、ハナカマキリの体色を形成する色素分子の生化学的解析を行った。昨年度の研究により、ハナカマキリ体色の赤色色素としてキサントマチンを同定したが、色素の抽出条件およびHPLCによる分離条件を検討した結果、ハナカマキリの色素抽出物には通常型のキサントマチンのほかに、分子上のカルボキシル基を1つ欠失した脱炭酸型のキサントマチンが含まれることを見出した。赤と黒を基調とした体色を持ち、カメムシ幼虫に擬態しているとされるハナカマキリの1齢幼虫では、相対的に多量の脱炭酸型が含まれていた。一方、花に擬態する2齢幼虫以降のステージでは、脱炭酸型キサントマチンの含有比率が次第に低下すると判明した。1齢幼虫の赤色部位はやや黄色味がかった赤色であるのに対し、後期幼虫の赤色部位は紫がかった赤色をしており、この色調の違いはキサントマチンの通常型と脱炭酸型の含有比率の違いによって生み出されている可能性が考えられた。また、ハナカマキリ後期幼虫の脚部にある花弁様構造の反射スペクトルを測定した結果、534nm付近に吸収ピークをもつスペクトル形状を示した。これは中性バッファー中における酸化型および還元型キサントマチンの吸収スペクトル(吸収極大波長はそれぞれ440nmと495nm)とは大きく異なる一方、還元型キサントマチンの凝集体の懸濁液の吸収スペクトルとは良く似た形状を示した。以上の結果から、ハナカマキリの花擬態に特有の赤紫色は、還元型キサントマチンが組織内に凝集体として存在することによって形成されていると推測された。
