Health examination was carried out on subjects (2 males and 5 females) who used arsenic containing hot water from the geothermal power station in Kyushu, Japan. They used the hot water only to take a bath over 4 years. The arsenic concentration measured by the atomic absorption method after generating AsH3 was 3.53μg/ml in the hot water. Waste water from the bath drained into a brook at the backyard and arsenic concentration in the brook were 0.54, 0.03 and 0.01μg/ml at the points of 0, 200 and 600m from the outlet, respectively.A special health examination was carried out on the following items: 1) Physical examination by doctors (dermatologist and general physician) 2) blood examination 3) urine analysis 4) biochemical and enzymological serum examination by SMA-12 5) determination of arsenic in urine and hair.Arsenic concentration in urine measured 3 times per day for each subject ranged from 58 to 178μg/l and it was within normal range, Arsenic concentration in hair was higher than normal range: the highest was 5.2μg/g, and for 5 of 7 subjects it was over 1μg/g. The result was suspected to be responsible for exogenous contamination such as washing of hair by hot water containing arsenic. There were no particular findings related to the arsenic poisoning.It must be emphasized that special attention should be paid to prevent the environmental popllution and health hazard caused by the hot water from geothermal power stations.

歯科外来における抜歯に関連した経口抗菌薬について,歯科ICTによる抗菌薬適正使用支援プロブラム(ASP)の前後で調査した.2015年1月~2018年12月において,電子カルテを用いた後ろ向き調査から抜歯当日の経口抗菌薬処方(術後投与)を抽出し,経口抗菌薬投与の有無,種類,期間を検討した.対象期間の後半(2017年1月)から,ASPとして抗菌薬適正使用に関する設問を含むe-learningを実施し,同時に関連情報を歯科系全医療スタッフで共有した.対象期間の普通抜歯は12,225件で,前半68.1%(4110/6036),後半50.4%(3120/6189)で経口抗菌薬が処方されていた.下顎埋伏智歯抜歯は4,740件で,前半90.5%(2130/2354),後半60.3%(1419/2354)で経口抗菌薬が処方されていた.ガイドラインによると普通抜歯では抗菌薬投与不要,下顎埋伏智歯抜歯では術前投与が推奨されており,適正使用化傾向が確認された.また,経口抗菌薬の種類は,第三世代セフェム系が激減し,普通抜歯では2015年上半期86.9%であったのが2018年下半期には28.3%に,下顎埋伏智歯抜歯では2015年上半期87.4%であったのが2018年下半期には8.5%となった.歯科ICTが主導するASPが歯科外来での抜歯における経口抗菌薬の適正使用に寄与したと推察された.

We report a case of long-term (about 10 years) limited mouth opening following a bilateral transtemporal approach for multiple cerebral aneurysms. A 41-year-old man with limited mouth opening was referred to our clinic for treatment. At the first visit, his maximum mouth opening distance was 13 mm between the upper and lower incisors and there were palpable indurations at the bilateral temporal muscles. We diagnosed this situation as a contracture of muscles, and performed bilateral coronoidectomy under general anesthesia. Mouth-opening exercises were started from one day postoperatively, and continued for 7 months. His maximum range of mouth opening is now maintained at 30 mm.

Studies of mental fatigue caused by exposure to the aircraft noise was carried out experimentally on 9 female students engaged in some intellectual performance. The tape-recorded noise of the flying Jet engine was controlled from 85dB(A) to 95dB(A) in the peak level. The subjects were exposed continuously to the noise during 50 minutes and 100 minutes, respectively, in an insulated room protected from general outer noise.Through the noise exposure period, the subjects performed intellectual tasks, that is, the Kraepelin- Uchida's test and card-sorting test. At the same time, pulse rates and pulse waves of their fingertips were measured. Before and after each exposure, the mental fatigue was measured by the critical fusion frequency (C.F.F.), the color naming test (C.N.) and the discriminative reaction of the multiple performance test (M.P.). And the information of subjective sensations of human fatigue were collected by the questionnaire, Cornal Medical Index (C.M.I.) were used for psychophysiological complaints. The control data of each subject were obtained by the same experiment except noise.The following conculusions were derived from observations. The grade of mental fatigue increased in the case of the noise exposure rather than in the case of the noiseless situation. In C.F.F., fatigue increased 13% under noise exposure of 50 minutes, 37% under that of 100 minutes. In C.N. and M.P. as wel as C.F.F. the same gradiance between the noise exposure and fatigue were found. Furthermore, fatigue revealed itself more clearly in C.N. than in C.F.F., namely, the rate of prolongation of the time required for color identifying exceeded the critical level of mental fatigue, while the rate of mental fatigue in C.F.F. was within the normal or allowable range.The results of the questionnaire of subjective sensations of fatigue and of the C.M.I. in the case of the noise exposure showed no remarkable differences compared with those of the noiseless situation. But, it was found that some complaints of sensations of fatigue increased slightly during noise exposure compared with those in the noiseless situation. These complaints were the symptoms probably caused by the sympagotonic hypertension. Moreover, from the observation of the pulse rates and pulse waves, it was recognized that a biological lags of the relaxation of the sympathetic nerves system might occur when they were released from the intellectual tasks.From the observation mentioned above, it is considered that there is a posibility of the inhibition of the learning effectiveness in school children when they are exposed to the aircraft noise such as the subjects were exposed to in this experiment. The exposed aircraft noise level used in this study, calculated from the peak levels and flying numbers, corresponds to 80 W.E.C.P.N.L.. It can be said that mental fatigue is induced markedly by the noise of 80 W.E.C.P.N.L.. It is suggested that the noise level of 80 W.E.C.P.N.L. is not harmless to human being in the case of intellectual performance, especially during school hours.

This study evaluated the exercise profile (heart rate, cycling speed and pedal cadence) during 25-30 km cycling and fitness and health level for adults (11 males: 69.6 ± 4.7 yrs; 6 females: 66.3 ± 4.9 yrs) with a recreational cycling habit (27.6 ± 14.8 km/week). Exercise intensity at a constant speed on a flat road during male and female cycling was 71.2 ± 11.5 and 66.8 ± 11.4% heart rate reserved (HRR), respectively. Exercise intensity over 60% HRR occupied 72% of cycling time. Peak intensity during male and female cycling was 89.2 ± 8.9 and 93.1 ± 6.1% HRR, respectively. VO2max and CS (chair stand)-30 test for male and female were 40.3 ± 4.3 and 37.7 ± 2.4 ml/kg/min, and 30.8 ± 3.1 and 30.1 ± 3.2 times, respectively. The muscle cross-sectional area of thigh extensor and flexor measured by MRI were 55.4 ± 6.5 and 58.3 ± 13.3 cm2 for male, and 45.5 ± 6.4 and 50.2 ± 5.7 cm2 for female, respectively. Blood profile for HDL-C (cholesterol), LDL-C and HbA1c (JDS) for male and female were 65.9 ± 8.2 and 67.9 ± 10.6 mg/dl, 112.3 ± 32.0 and 130.6 ± 12.3 mg/dl, and 4.8 ± 0.4 and 4.7 ± 0.1%, respectively. Fitness level and blood profile results were superior to those of the same aged adults. We concluded that the exercise intensity of cycling by middle and older adults with a recreational cycling habit is high and their fitness and health level are higher than average adults.

急性タリウム中毒患者及び正常人の生体試料中タリウムのスクリーニング法について検討した.尿及び血液は0.1N硝酸による単純希釈液,頭髪は毛根部より5mmずつ切断したものを測定試料として,黒鉛炉原子吸光法により直接定量を行った.加熱プログラム特に灰化段階の温度のコントトール及び測定値の回収率での補正により,生体試料中タリウムを簡便かつ短時間に測定できた.従って,本法は中毒症状が発現する程度の暴露を受けた被験者のスクリーニング法として極めて有用な方法と考えられた.

我が国においては, 産業医学卒後教育に関する系統的なシステムは今日まで何等確立されていない. しかし, 産業医科大学設立の時点で, 特色ある産業医学の教育・研究は卒後教育において充実させるよう示されており, したがって本学卒業生や産業医に対して産業医学教育を行うことは本学の重要な使命の1つであると言える. 昭和59年春第1回の卒業生を世に送り出すに当り, 本学の産業医学卒後教育基本講座のカリキュラムや生涯教育を含めた我が国の産業医学教育のあり方を, 日本の現状を踏まえて考えることが必要であろう. その参考資料として, 産業医学に関する歴史的背景と経験を有する英米両国の現状を紹介する.(1983年8月15日 受付)
