1-phenyl-1-hydroxy-n-pentane (PHP) をラット十二指腸内へ注入し, 血中セクレチン濃度, 膵液, 膵アミラーゼ分泌量を同時に測定した. さらにPHPの作用に対するソマトスタチン (GIF) の影響もあわせて検討した.PHP 200mg/kg/min の注入により血中セクレチン濃度は, 5分後には前値の4~5倍にまで増大したが, PHP 50mg/kg/h 注入では血中セクレチン濃度は変動しなかつた. しかし両注入量に対する膵外分泌反応には差がなかつた.PHP 200mg/kg/min に対するセクレチン反応はGIFで完全に抑制されたが, 膵外分泌反応は認められた. 以上より PHP のセクレチン分泌作用は比較的弱く, セクレチン以外の膵外分泌刺激因子 (例えばCCK•PZ) に対し, 強い分泌刺激作用を示した.

In the echo cancellation, the double-talk situation when both the near-end signal and far-end signal are presented degrades the performance of echo cancellation with the LMS or the NLMS algorithms. In order to obtain an acceptable performance even in the presence of the double-talk, the authors proposed the expanded correlation least mean squares (ECLMS) algorithm but this algorithm does not give a fast conver-gence characteristics still. The purpose of this paper is to derive an orthogonal ECLMS algorithm with the lattice strucure in order to speed up the convergence characteristics and to reduce the computational load for the adaptation. The validity of this algorithm is evaluated by computer simulations in the echo cancelling problem.

This paper examines campaign strategies of parties in elections, and investigates a role of a negative campaign. It shows that a negative campaign can be an optimal strategy in some cases. One interesting case is that one party chooses a positive campaign that accommodates its pledge to that of opponent and the other party chooses a negative campaign that discriminates opponent's pledge from its own in a Nash equilibrium. Although positive campaigns only reveal positive effects of policies, the negative campaign works to reveal negative effects of the opponent's policy. Thus negative campaigns contribute to show the true effects of policies to voters.

Aims: Several guidelines propose target levels (TLs) of atherosclerotic risk factors (ARFs) to reduce atherosclerotic cardiovascular diseases; however, few data are available regarding the attainment statuses of TLs in Japan. In this study, utilizing the data obtained from the annual “Specific Health Check and Guidance in Japan” conducted from 2008 to 2011 (approximately 280,000 subjects each year), we determined TL attainments of ARFs in cardiovascular high-risk subjects.Methods: Those who had suffered from cerebrovascular disease (pCVD) or coronary heart disease (pCHD) or were receiving diabetes mellitus treatment (DM) were selected, and the rates of subjects that attained TLs of blood pressure (BP), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TGs) and glycated hemoglobin (HbA1c) were analyzed.Results: Approximately 70% of pCVD or pCHD and 35% of subjects with DM attained TLs of BP. With regard to HbA1c, >90% of pCVD or pCHD and approximately 50% of subjects with DM attained TLs. With regard to LDL-C, <25% of pCHD females and approximately 35% of pCHD males and 50%–55% of subjects with pCVD or DM attained TLs. The TL-attainment rates of HDL-C and TGs were approximately 90% and 75%, respectively, for the three diseases. Analyses of time course changes in their attainment statuses revealed that the attainment rates of BP and LDL-C significantly improved in all the diseases.Conclusions: TL-attainment rates of BP and LDL-C were not as high as those for HDL-C, TGs, and HbA1c; however, they both showed highly significant improvements during the study period.

The output of the seismic devices commonly employed for the monitoring of debris flows, such as geophones and seismometers, is a voltage that is directly proportional to the ground vibration velocity. The output signal in analogical form is usually digitalized at a fixed sampling frequency to be opportunely processed. The processing is performed to both reduce the amount of data to be stored in a data-logger and to reveal the main features of the phenomenon that are not immediately detectable in the raw signal, such as its main front, eventual subsequent surges, the wave form and so on. The processing also allows a better and sounder development of algorithms, when seismic devices are employed for warning purposes. However, the processing of the raw signal alters in different ways the original raw data, depending on the processing method adopted. This may consequently limit or reduce the efficacy of the warning. Different methods of data processing can be found in literature, each with its own advantages and shortcomings. In this paper we will explore and discuss the effects of some of these latter on the efficacy of the algorithms employed for warning, applying them to the seismic recordings obtained in the instrumented basins of Gadria (Italy), Rebaixader (Spain) and Illgraben (Switzerland).

下肢の幻肢痛患者に対して健常者の下肢の運動の動画をタブレット型端末装置(iPad®)に取り込み,患者の患側肢の上に保持して動画を再生し,その動きをイメージすることで除痛を得ている症例を報告する.症例は33歳の女性.X-14年1月交通事故が原因で左大腿部切断.幻肢痛に対してX-3年10月実際の鏡を用いての鏡療法を開始,X-2年7月iPad®を用いた鏡療法を開始した.従来の鏡療法導入後痛みは軽減したが,施行にあたっては大きな鏡を必要とする.一方,iPad®を用いた鏡療法は時と場所を選ばず簡便に実施可能である.また,非断端肢に運動障害があっても施行可能であり有用であった.

At the Nagasu fishing port of Oita Prefecture, the field survey on environmental-impact-assessment was carried out before and after dumping dredged sand into the shallow sea area. As comparing both field survey results, influence on fishing ground environment by dumping dredged sand into the shallow area was examined and evaluated. As a result of measuring the number of species and individuals and the amount of wet-weight of macro benthos in both bottom material, it showed that the condition of macro benthos of bottom material after dumping was almost similar to that before dumping. Therefore, it is considered that the influence of dumping dredged sand into shallow sea area around Nagasu Fishing Port would be temporary and little impact. In addition, planning the time of dumping dredged sand in this area, the consideration of avoiding the time of larva and juvenile of Marbled sole (Pleuronectes yokohamae) and the time of cultivate laver would be required.

Schwann cell tumor occurring in the intestines is rare . A 68-year-old female came to our hospital because of hematemesis. Barium enema and colonoscopic examination revealed submucosal tumor in the sigmoid colon. Laboratory data showed mild anemia . No other abnormal finding was found in the blood chemistry. Tumor marker levels of carcinoembryonic antigen (CEA), CA19-9, alpha feto protein (AFP) and neuron specific enolase (NSE) were within normal limits. The exploratory laparotomy confirmed a large sigmoid colon tumor. She received sigmoid colectomy. The resected specimen was a submucosal tumor with central depression, measuring 4.7×3.5×3.0cm in size. The cut surface of the tumor was yellowish hue with necrosis. Histological examination showed spindle-shaped tumor cells with palisading comma-shaped nuclei and the nuclear pleomorphism. Immunohistochemical examination revealed that the tumor was positive for S-100 protein staining, and negative for Actin and for H.H.F. staining. These findings showed that this tumor was of Schwann cell origin. We report here the case in detail of a schwannoma in the sigmoid colon.

本稿では,水・油・界面活性剤から成る系における自発的な界面運動について記述している。化学種の濃度が水相と油相間で非平衡である時,界面で様々な自励振動が見られる。今回は,その自励振動のうち,特に界面張力の周期的な増加に注目し,界面張力変化と界面運動との相関について説明した。界面張力が急激に増加すると接触角も急激に変化し,その結果界面張力間のバランスが崩れて運動が起こることを明らかにした。また,油水系では界面運動の駆動力は水相と油相間での界面活性剤の濃度勾配である。すなわち,等温条件下で化学的なエネルギーから機械的な運動を直接取り出している系であると言える。これは,例えば筋肉におけるエネルギー変換の機構と比較すると1)非平衡状態で起こり,2)熱エネルギーを介さない化学→機械エネルギーの直接変換系であり,3)空間的に非対称性を取り入れることによって運動方向の制御が可能である,といった点などにおいて共通性があり,生物の運動のメカニズムを探索する上で有効であると考えている。
