| 抄録 | Lipoprotein(a), or Lp(a), is a low-density lipoprotein-like particle largely independent of known risk factors for, and predictive of, cardiovascular disease (CVD). We investigated the association between baseline Lp(a) levels and the progression of coronary artery calcification (CAC) in patients with hypercholesterolemia undergoing statin therapy. This study was a sub-analysis of a multicenter prospective study that evaluated the annual progression of CAC under intensive and standard pitavastatin treatment with or without eicosapentaenoic acid in patients with an Agatston score of 1 to 999, and hypercholesterolemia treated with statins. We classified the patients into 3 groups according to CAC progression. A total of 147 patients (mean age, 67 years; men, 54%) were analyzed. The proportion of patients with Lp(a) > 30 mg/dL significantly increased as CAC progressed (non-progression; 5.4%, 0 |

| 抄録 | Neurodegenerative diseases in which tau accumulation plays a cardinal role in the pathogenic process are called tauopathies, and when tau isoforms having four repeats of the microtubule binding sites, four-repeat tau, are selectively accumulated as pathological hallmarks, the term four-repeat tauopathy is used. The major four-repeat tauopathies are progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), and argyrophilic grain disease (AGD). Historically, neuronal cytopathologies, e.g., neurofibrillary tangles and ballooned neurons, were emphasized as characteristic lesions in PSP and CBD. Now, however, astrocytic tau pathologies, i.e., tufted astrocytes (TAs) and astrocytic plaques (APs), are considered to be highly disease-specific lesions. Although granular/fuzzy astrocytes (GFAs) frequently develop in the limbic system in AGD cases, the specificity is not conclusive yet. Some AGD cases have a few TAs, and to a lesser frequency, a few APs in the frontal cortex and subcortical nuclei. The number of astrocytic tau pathologies including TAs and GFAs increases with the progression of AGD. In this paper, histopathological features of astrocytic tau pathologies in PSP, CBD, and AGD are first reviewed. Then, recent findings regarding the coexistence of these tauopathies are summarized from a viewpoint of astrocytic tau pathologies. Further biochemical and pathological studies focusing tau-positive astrocytic lesions may be useful to increase understanding of the pathological process in four-repeat tauopathies and to develop novel therapeutic strategies for patients with these diseases. |

| 抄録 | We treated two patients with a rare metaplastic carcinoma of the breast. Patient 1：A 32-year-old woman presented with a rapidly growing mass（ 7cm） in her right breast. We diagnosed cT3N0M0 Stage IIB breast cancer and performed a radical resection. The pathological diagnosis was triple-negative metaplastic carcinoma with a Ki-67 value ＞30%. Postoperative adjuvant chemotherapy and radiotherapy were performed. Patient 2：A 66-year-old postmenopausal woman presented with a left breast mass. We diagnosed cT1N0M0 Stage I breast cancer and performed a radical resection. The pathological diagnosis was triple-negative metaplastic carcinoma with a Ki-67 value ＞30%. Postoperative adjuvant chemotherapy was performed. Patients 1 and 2 have achieved relapse-free survivals of 1 year＋2 months and 10 months, respectively. Metaplastic carcinoma of the breast is a rare tumor, and its prognosis is not favorable. The only available treatment is that used for invasive ductal carcinoma；a more specific treatment has not been established. The accumulation of further similar cases and the development of a novel effective treatment are desired. |

| 抄録 | A 73-year-old woman was admitted for closer investigation into an abdominal tumor. Abdominal ultra-sonography, CT, and magnetic resonance imaging showed a discrete abdominal tumor. Especially on MRI, the tumor appeared as a relatively ill-defined whorled soft-tissue thickening within the mesenteric fat, causing angulation or speculation of adjacent bowel mesentery. Surgery was performed under a presumptive diagnosis of a mesojejunum desmoid. The tumor was invading the transverse mesocolon and mesojejunum as well as the third portion of the duodenum and the middle colic artery, and it was close to but apart from the superior mesenteric artery. The tumor was resected, including removal of part of the duodenum and transverse colon. The specimen contained a white solid tumor measuring 14×12×8cm. Pathologic examination showed differentiated fibroblasts and copious collagen fibers. The tumor was negative for CD34, c-kit, S-100, and α-SMA, but positive for β-catenin. On the basis of these findings, we established a diagnosis of mesenteric desmoid tumor of the small intestine. The patient has been followed postoperatively for 2 years, no sign of recurrence, to date. |

| 抄録 | 本研究はソーシャルスキル、進路選択能力および進路選択自己効力感（CDMSE）の関係性について定量調査に基づき分析している。先行研究では、進路決定および進路不決断を規定する要因について議論されてきたが、ソーシャルスキル、進路選択能力、CDMSE の3 要因を取り上げて分析した研究は非常にまれであった。対人関係能力を進路決定の現場では重視しているにもかかわらず、ソーシャルスキルと進路選択との関係性は未解明であった。本研究では、国立大学の大学生44 名を対象にサーベイ調査を実施した。調査結果をBandura による自己効力感理論をベースに定量分析したところ、ソーシャルスキルは進路選択能力およびCDMSE にポジティブな影響を及ぼすことが明らかになった。また、ソーシャルスキルは進路選択能力を媒介して、CDMSE を向上させることも確認された。分析結果からキャリア教育において、対人関係能力を高めるプログラムを導入することが大学生の進路選択行動を促進する効果があるという実践的示唆が得られた。 |

| 抄録 | The Okayama Association for Laboratory Science, established on December 7, 1982, celebrates its 35th anniversary on December 7, 2017. The association was established to provide opportunities for researchers interested in laboratory animals and animal experiments to assemble beyond the borders of universities, faculties, and institutions to exchange their knowledge and information, as well as help promote their research activities and advancement of community science. The executives, auditors, and other members of the association have organized and held workshops and issued newsletters under the leadership of former presidents. The association has been able to implement research activities for a long period of time thanks to the advice of regular members and the support of supporting members. The workshops have been held twice a year since 1990. A total of 74 workshops(regular conferences), as well as symposiums, have been held and 33 research bulletins (proceedings) have been issued over the last 35 years. We have summarized the workshops and symposiums etc. that have been held. |

| 抄録 | The deodorizing effect of weak acid hypochlorous solution against ammonia was investigated. When atomized particles of weak acid hypochlorous solution contacted ammonia, the ammonia concentration decreased in a concentration-dependent manner. The deodorizing effect was also observed against ammonia generated from the used floor cover for mice. When the floor mat was present, the ammonia concentration gently decreased but then rapidly decreased when the floor mat was removed. In the future, we will examine effective spraying conditions for weak acid hypochlorous solution in laboratory animal facilities, and we will also proceed with the validation of effects other than spraying. |

| 抄録 | Acoel flatworms can move in a variety of ways such as muscular and ciliary movements via cytoskeletal elements and their neural regulations. However, those locomotive mechanisms have not yet been fully elucidated. In this study, we examined the distribution of cytoskeletal elements including filamentous actin (F-actin) and tubulin, and the neuroanatomical organization in an acoelomorph worm, Praesagittifera naikaiensis (P. naikaiensis). Video microscopy revealed the elongation/contraction and the bending/rotation processes, and the ciliary gliding movement of P. naikaiensis. Histochemical and morphological analysis demonstrated that F-actin networks of inner longitudinal and outer circular muscle fibers were positioned along the entire surface of the body, and that the average distance between the circular muscle fibers in the contracted organism was decreased in the anterior region compared with that in the elongated organism. Electron microscopy showed dense bodies on the muscle cells of P. naikaiensis, which indicates that those muscle cells have the appearance of vertebrate smooth muscle cells. Immunohistochemical analysis revealed that -tubulin-positive signals on the ciliary microtubules had close contact with the F-actin network, and that neurite bundles labelled with anti dSap47 antibody as a neuronal marker run along the anterior-posterior body axis. These results indicate that the well-organized cytoskeletal elements and their neural control systems are preserved in P. naikaiensis, and that their mechanisms involved in those regulation systems are similar to those vertebrate systems. Further studies are needed to clarify the physiological mechanisms underlying the muscular and ciliary movements in P. naikaiensis. |

| 著者 | 山口 良文| |
| 抄録 | Hibernation is an adaptive strategy for surviving during periods with little or no food availability, by profoundly reducing the metabolic rate and the core body temperature (Tb). Mammalian hibernators store fat extensively in white adipose tissues (WATs) during pre-hibernation period to prepare for hibernation. Thus, they undergo adaptive body remodelling in autumn, the pre-hibernation period, prior to hibernation, whereas little is known about the physiological and molecular mechanisms of the pre-hibernation remodelling. Syrian hamsters (Mesocricetus auratus) are facultative hibernators that can hibernate irrespective of seasons when exposed to prolonged short photoperiod and cold ambient temperature (SD-Cold) conditions. We found that before the initiation of hibernation, the body mass of Syrian hamsters decreased below a threshold, indicating that hibernation in this species depends on body condition. Global profiling of gene expression in various tissues of animals during the pre-hibernation period and hibernation period identified adaptive changes for hibernation at molecular level. Thus, Syrian hamsters as a model animal to study hibernation provide us a unique and convenient opportunity to analyse molecular and physiological mechanisms of adaptive pre-hibernation remodelling under a laboratory condition. |

| 抄録 | Extracorporeal excretion of mercury by two molybdenum complexes was investigated using mice after injection of metallic mercury or mercuric ion. After injection of metallic mercury into mice, the mice that received the incomplete cubane-type sulfur-bridged nitrilotriacetato molybdenum (IV) complex ([Mo3S4(Hnta)3]2-, referred to as the NTA complex) had the highest mercury content in their urine on the first day, followed by L-cysteine solution and then water. On the other hand, after injection of mercuric ion, the urinary mercury excretion from the mice that received various concentrations of the incomplete cubane-type sulfur-bridged cysteinato molybdenum (V) complex ([Mo2O2S2(cys)2]2-, referred to as the CYS complex) showed a higher level than that of mice that received water (control group). The mercury content in the heart and lungs of the group that received the CYS complex solution decreased in comparison with that of the group that received the water. At the same time, the mercury level in the kidneys for the CYS complex solution group showed the tendency to increase relative to the group that received water. |

| 抄録 | Runx3 is a transcription factor that belongs to the Runx family. Female Runx3 knockout (Runx3−⁄−) mouse was anovulatory and infertile. Ovarian transplantation experiment suggested that lack of ovulation in Runx3−⁄− mice was caused by alteration of gonadotropin secretion in Runx3−⁄− mice. Cyp11a1 mRNA expression was less in Runx3−⁄− mouse ovaries than in wt ones. Hypothalamic Gnrh1 mRNA was increased, and Kiss1 mRNA expression in the anteroventral periventricular nucleus was decreased, but Kisspeptin mRNA in the arcuate nucleus was increased in Runx3-/- mice. Pituitary Fshb mRNA levels were increased in Runx3−⁄− mice. Cholesterol side-chain cleavage enzyme gene (Cyp11a1) expression was decreased in ovaries of Runx3−⁄− mice. These findings suggest that anovulation in Runx3−⁄− mice was partly due to the alterations in hypothalamus-pituitary-ovary system. Runx3 plays a key role in female reproduction through alteration of gonadotropin secretion. |

| 抄録 | In this paper, we prove that the etale fundamental group of a hyperbolic curve over an arithmetic field [e.g., a finite extension field of Q or Qp] or an algebraically closed field is indecomposable [i.e., cannot be decomposed into the direct product of nontrivial profinite groups]. Moreover, in the case of characteristic zero, we also prove that the etale fundamental group of the configuration space of a curve of the above type is indecomposable. Finally, we consider the topic of indecomposability in the context of the comparison of the absolute Galois group of Q with the Grothendieck-Teichmuller group GT and pose the question: Is GT indecomposable? We give an affirmative answer to a pro-l version of this question |
