CT and MRI are indispensable for routine medical examination of neurovascular disorders. This article describes the imaging findings in acute infarction and carotid plaques, knowledge of which is essential for clinics of equilibrium disorders. Diffusion-weighted images are indispensable for detecting acute infarction, and perfusion MRI also yields important information about the ischemic status. Carotid bifurcation is one of the frequent sites of involvement in atheromatous diseases. A variety of imaging modalities are available for the evaluation of carotid plaques, including conventional contrast angiography, CT, ultrasound, and MRI. MRI is a non-invasive imaging method that reflects the chemical composition, concentration, water content or physical status of the tissues examined.

A diagnosis based on the presumed mechanism of stroke onset is useful for management strategies in acute ischemic stroke. Ninety-two patients with embolic (cardiac or artery-to-artery) and 107 with non-embolic (thrombotic or hemodynamic)stroke were diagnosed on strict cerebral angiographic criteria alone. To clearly discriminate between these two groups, the neurological and computed tomographic (CT) findings were then compared. Rapidity of onset, vomiting, urinary incontinence, level of consciousness, cervical bruit, anisocoria, tongue deviation, sensory disturbance, and CT findings (location of hypodense area, findings of brain edema and hemorrhagic transformation) were discriminatory factors between the two groups (p<0.01). According to these 11 items, we prepared a numerical table for quantitative differential diagnosis. A diagnostic accuracy of 98.9% for embolic and 87.9% for non-embolic stroke in internal verification, and 90.0% and 82.9%, respectively, in external verification was observed. The differences in clinical features and CT findings between embolic and non-embolic stroke may reflect the pathophysiological mechanisms of the occlusive process of cerebral artery as well as the extent and severity of ischemia.(Internal Medicine 37: 141-148, 1998)

戦前期の皇室財産(御料地)は、憲法制定・議会開設を前にした明治22年前後に編入された。この概要は『帝室林野局五十年史』などでも知れるが、編入にあたっての巡回(現地調査)、復命の内容など、その具体的実態は未解明のままであった。そこで、本稿では、宮内庁が利用制限を解いた『地籍録』に基づいて、群馬県の場合の解明に取り組むこととした。群馬県へは大木真備が派遣された。巡回に当たっては、県側に資料の提出を求め、27の対象箇所を決めて出発した。しかし、「巡回日誌」などは不明なので、これを埋める資料として、肥田長官宛の書簡2通を活用して行程やそこでの問題点を把握した。そして、大木の「復命書」によって、これまで「将来有益なる土地と然らざる土地とを区分し」たと『明治天皇紀』に書かれていた内容の具体的把握をおこない、これに基づいて選定基準をまとめ、最後に、この根拠には楫取素彦の「意見書」があったことを述べてまとめとした。

釣りをする場合、針に餌をつけそのまま水に垂らしても、針は浮いてしまう。そのため、錘を着用するが、その錘は、コストの面と加工性の優位性によりそのほとんど鉛から作られている。一本釣りだけでなく、他の漁法である底引き網や定置網等の網の部分やそれを支えるロープの部分も、錘がなければ浮いてしまうので、鉛製の錘を装着することが当然のこととしてある。よって、現在の鉛の錘の代替品が見当たらない状況においては、漁業と鉛の関係は切り離すことができない状況である。本研究では、寒ブリで有名な富山県の定置網における漁網を取り挙げ、その適正処理とリサイクルへの課題を検討した。

Background Canine mammary gland tumors can be used as predictive models for human breast cancer. There are several types of microRNAs common in human breast cancer and canine mammary gland tumors. The functions of microRNAs in canine mammary gland tumors are not well understood.Methods We compared the characterization of microRNA expression in two-dimensional and three-dimensional canine mammary gland tumor cell models. We evaluated the differences between two- and three-dimensional cultured canine mammary gland tumor SNP cells by assessing microRNA expression levels, morphology, drug sensitivity, and hypoxia.Results The expression of microRNA-210 in the three-dimensional-SNP cells was 10.19 times higher than that in the two-dimensional-SNP cells. The intracellular concentrations of doxorubicin in the two- and three-dimensional-SNP cells were 0.330 ± 0.013 and 0.290 ± 0.048 nM/mg protein, respectively. The IC50 values of doxorubicin for the two- and three-dimensional-SNP cells were 5.2 and 1.6 μM, respectively. Fluorescence of the hypoxia probe, LOX-1, was observed inside the sphere of three-dimensional-SNP cells without echinomycin but not in two-dimensional-SNP cells. The three-dimensional-SNP cells treated with echinomycin showed weak LOX-1 fluorescence.Conclusion The present study showed a clear difference in microRNA expression levels in cells cultured in a two-dimensional adherent versus a three-dimensional spheroid model.

A 2-month-old female mixed cat was emaciated due to dysphagia, and inspection of the mouth revealed a 2 cm pedunculated mass elongated from the palate, which occupied the oral cavity. The mass was surgically removed, and histopathological examination revealed that the tumor was composed of three germ cell layers: ectodermal (skin and skin appendages), mesodermal (cartilaginous and osseous structures), and endodermal (glandular and respiratory mucosa) tissues. An immature teratoma was diagnosed because of the presence of immature neuroectodermal tissues, and the presence of nephroblastic components was a characteristic finding in this case. This is the first report of an oropharyngeal teratoma in cats and the first case of an immature teratoma with nephroblastic components in a domestic species.
