症例は41歳男性.B型WPW症候群に伴うwide QRS頻拍に対し,電気生理学的検査を施行した.心室連続刺激中の心房最早期興奮部位はHis束電位記録部位であったが,心室早期刺激で左側後壁副伝導路の存在が示唆された.心室早期刺激でclinical wide QRS頻拍(SVT1)が誘発され,右側側壁副伝導路を順行,房室結節を逆行する逆行性房室回帰性頻拍と診断した.SVT1は室房伝導時間が短縮し,His束電位が心室(V)波に重なるSVT2へと変化した.その間,His –心房(A)波間隔は一定であったことからSVT1の室房伝導は機能的右脚ブロックであったのに対し,SVT2ではそれが解除されたと考えられた.さらにその後の心室早期刺激でwide QRS頻拍SVT3が出現し,これは室房伝導の順序は変化しないまま,narrow QRS頻拍SVT4に変化した.これらは房室結節を順行,左房後壁副伝導路を逆行する順行性房室回帰性頻拍と診断した.wideからnarrowへの変化はCoumel現象による左脚ブロックが解除されたためと考えられた.さらに副伝導路間を旋回するSVT5と,通常型slow-fast房室結節回帰性頻拍(SVT6)も誘発された.以上より,順伝導のみの右側副伝導路,潜在性左側副伝導路,房室結節遅伝導路を焼灼し終了した.

Micro-strucure, micro-hardness and micro-absorbed impact energy in the Japanese sword have been investigated to clarify excellent mechanical properties of the Japanese sword. The Japanese sword specimen used in the present research has been made by using TSUKURIKOMI process which combines four kinds of steels; HAGANE (edge), SHINGANE (core), MUNEGANE (back) and KAWAGANE (side) steels, with different carbon contents. By this process, HASAKI (edge) side becomes high carbon steel and MUNE (back) side possesses low carbon steel. The cooling velocity in quenching of the Japanese sword is controlled by TSUCHIOKI treatment which coats the clay thinner in the HASAKI side and thicker in the MUNE side. The HASAKI side is quickly cooled and the MUNE side is slowly cooled. The micro-structure in the HASAKI side shows martensite while the MUNE side shows the coexist structure of ferrite and pearlite. The HASAKI side has a lower value while the MUNE side shows a higher value in the micro absorbed impact energies obtained with the 1.0 and 0.7 mm square miniaturized specimens. It has been shown clearly that the TSUKURIKOMI and the TSUCHIOKI processes give the excellent gradated balance of strength-toughness to the Japanese sword.The ORIKAESHI (folding) forging has an effect both on the carbon content and as quenched hardness in HAGANE steel. The most suitable times of ORIKAESHI cycles which adjust to the carbon content of 0.55-0.60 mass% and hardness of 800HV1 have been determined to be thirteen times. These times of ORIKAESHI cycles correspond to the optimum traditional cycles lying between twelve and fifteen times. The present research from the viewpoint of the metallurgy sheds light on the empirical rule in the traditional Japanese sword processing.

The Japanese sword has excellent strength-toughness balance given by two traditional processes. One process is compounding of inner tough iron and outer strong steel. And the other process is cooling-rate control quenching by using thickness of clay-coating before quenching. However, it is a precondition for acquiring high strength-toughness that carbon content of sword parts are regulated in proper quantities. Carbon content of sword parts is very important and controlled under forging process which contains TSUMI-WAKASHI (forge-welding piled steel chips) work and fold-forging.Therefore, changes in carbon content of TAMA-HAGANE steels and carbon steels under traditional forging process were investigated in this study. Changes in carbon content depended on enclosing decarburized or carburized surface in steel as forge-weld interface. Total changes in carbon content were proportional to total layers of included surface in steel. Changes in carbon content per one forge-welded layer. “d (mass%/layer)” was ruled by carbon content of raw materials “C0 (mass%)”. When C0 is over 0.2 mass%, carbon content of forged steel is decreasing and the more C0, the more |d |. C0 is under 0.2 mass%, carbon content is increasing. The mass of forged steels is 4% increasing per one fold-forging cycle, but d is not affected by changes in mass of them.

Prospective epidemiological studies of blood pressure in a high-salt population in northeastern Japan were investigated along with dietary habits such as miso soup, rice, apple, fish, milk and sake consumption as well as smoking habits.<br>Blood pressures of the populations in 3 villages were determined once or twice a year by mass surveys from 1954, 1957 or 1958 through 1975. The means and transitions of the personal blood pressure were calculated by regression analysis of the data obtained during each entire period.<br>The number of persons was 1127 males and 1369 females and the response rate was 98.7 percent. The average number of times of determination of blood pressure for a person was 12.9.<br>Stepwise multiple regression analyses were run with the means and transitions of systolic and diastolic blood pressure as the dependent variables and the life styles of the population in 1958 as an independent variable based on data of persons whose blood pressures were determined 5 or more times during the entire period. According to the backward stepwise method this study confirmed the positive relationship of age and sake drinking and the negative relationship of apple eating habits to blood pressure.

The Japanese government is promoting use of wood in recent years, because of the environmental provision of carbon dioxide fixation. The authors developed “FR wood”. “FR wood” is the only technique with simply use one tree species in Japan. When considering actual application, it is necessary to verify the fire-safety of joint parts in addition to the development of member. In particular, verification of the joint with the steel frame member is important. So, the specimens of the join part were constructed and fire resistance test was conducted. The resistance performance of steel members and wood members was confirmed.

We report two cases in which drooling was reduced by percutaneous use of scopolamine ointment. Case 1: A 75-year-old female patient with amyotrophic lateral sclerosis (ALS). In addition to low-pressure continuous suction of the mouth, she was started on scopolamine ointment applied over the postauricular region. Before the ointment was prescribed, the volume of continuous suction was 400 ml/day, whereas it decreased to 150 ml on day 1 and to 200 ml on day 2 after the start of ointment application. Case 2: A 17-year-old female patient with cerebral palsy. If the score on Numeric rating scale (NRS) for the caregiver’s burden before the start of ointment application was 10, the score decreased to 2–4 after 4 hours and 1–3 after 24 hours of ointment application. Two and a half days after the ointment application, there was an objective increase in the amount of saliva, so that the application interval was shortened from every 3 days to every other day. Thereafter, there was a consistent decrease in the amount of saliva. Scopolamine is known to have side effects such as dryness of the mouth, drowsiness, blurred vision and mydriasis, constipation, and urinary retention. However, even after several months of use, no side effects have been observed in either case. We present some review of the literature, including on instructions for preparing and using scopolamine ointment.

症例1 : 74歳男性. 繰り返す上室頻拍のため, 心臓電気生理学的検査 (EPS) を行い, slow-intermediate型の房室結節回帰性頻拍 (AVNRT) が誘発された. 解剖学的遅伝導路 (SP) 部位に対して焼灼を行ったが, その後もAVNRTが誘発されるため, 冠状静脈洞 (CS) 内およびSPの左房側より通電したところ誘発不能となった. 症例2 : 77歳女性. 動悸のため来院. 動悸時の心電図ではRR間隔が交互に変化する上室頻拍を認めた. EPS上, 室房伝導はなく, 洞調律1拍に対してAH間隔の異なる心室応答が2拍出現したことにより, 房室二重伝導路によるdouble ventricular response (DVR) と診断した. 右房側より解剖学的SP部位を焼灼したが無効であり, CS内, 左房側より通電しDVRは消失した. 後日再発したため, 再度EPSを行った. 解剖学的SP, CS内, 左房側より通電したが, DVRの消失には至らなかった. 通電により, 一時的にWenckebach型房室ブロックとなったため, それ以上の通電を行わず終了した. 通電は不十分であったが, 現在は頻拍の再発なく経過している.
