After the severe accident in the Fukushima-1 nuclear power plant, a large amount of contaminated stagnant water has been produced in turbine buildings and surrounding areas. This rapid communication reports the calculation of the radionuclide inventory in the core, the collection of the measured inventory in the stagnant water, and the estimation of the radionuclide release ratios from the core to the stagnant water. The present evaluation is based on data obtained before June 3, 2011. It was revealed that the release ratios of tritium, iodine and cesium were several tens of percent, while those of strontium and barium were smaller by one or two orders of magnitude. These release ratios of the Fukushima accident were equivalent to those of the TMI-2 accident.

The side effects of peroral bisphosphonate may cause mucous membrane disorders and oral exulceration if individuals dissolve the drug inside the oral cavity on oral administration. We experienced two cases in which we strongly suspected mucous ulcurs due to this drug. Finally, the oral exulceration disappeared after providing instructions on correct administration. An 83-year-old woman was referred because of exulceration of the right mandible. She suffered from osteoporosis, thoracic vertebra compression fracture, and dementia, while taking alendronate weekly. The exulceration appeared from the right lower lip to the right mandibular molar gingiva when we absorbed pooled saliva in the right oral cavity when the patient was lying down. We instructed the patient to confirm that the tablet was completely swallowed. The ulcers in the oral cavity completely disappeared 17 days after presentation. A 74-year-old woman with osteoporosis presented because of bleeding and pain in the gingiva of the right mandible. She was taking monthly minodronate while wearing incompatible dentures. Exulceration occurred with peripheral redness ranging from the right buccal mucosa to the right molar gingiva of the mandible and the tongue/floor of her mouth, along with a ventrolateral tongue. We taught her how to swallow minodoronate correctly without dentures, and the ulcers healed 4 weeks later.

Leigh症候群を発症後に, mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS) を合併し, ミトコンドリア遺伝子の10191 T>C変異が同定された1例を経験した. 症例は26歳女性. 11歳時に外斜視で発症し, juvenile Leigh症候群と診断された. 26歳時に頭部MRIで血管領域に合致しない梗塞像が多発し, MELASを合併したと診断された. 文献考察からMELAS/Leigh overlap症候群の臨床像は発症年齢, 症状, 予後の点でLeigh症候群とは明確に異なる点が推測された. Overlap症候群の表現型の多様性はヘテロプラスミーを含めた多面的な遺伝要因の関与が推定された.

症例は30歳女性.25歳頃から数回にわたり皮質盲症状を呈し近医を受診した.脳梗塞様の画像所見と糖尿病の病歴からミトコンドリア病が疑われたが,血清および髄液乳酸値が正常,筋病理に異常を認めないことから確定診断には至らなかった.30歳時に意識障害と皮質盲症状,頸部および右上肢の不随意運動を呈して当院を受診.頭部MRIで両側大脳基底核の異常信号とMRスペクトロスコピーで乳酸ピークの増大を認め,髄液乳酸値の高値,ミトコンドリア遺伝子解析でm.4296G>A遺伝子変異を認めたことからミトコンドリア脳症と診断した.成人発症のm.4296G>A遺伝子変異の報告は非常に稀であると考え文献的考察を行い報告する.

Original KIVA code cannot take account for the spray and combustion processes of multicomponent fuels. Therefore, it is necessary to produce the sub-models for multicomponent fuel using KIVA code. In this study, the modeling of detailed physical properties and evaporation process for multicomponent fuel was conducted. In addition, the effects of fuel composition in multicomponent fuel on vapor distribution, spray tip penetration, vapor mass and evaporation rate, and sauter mean diameter were numerically investigated by using KIVA 3 V code with this multicomponent fuel spray model. From the numerical results, the spray characteristics of multicomponent fuel varied with a change in mixing fraction in multicomponent fuel. Especially, the evaporation of multicomponent fuel was not necessarily improved, even if much amount of high volatility fuel was mixed in the multicomponent fuel.
