    In the previous report, the author demonstrated that the electric construction workers were exposed to the high risk of low back pain, and discussed on the ways to prevent and to treat their occupational disorders. He concluded that the improvement of their working conditions, especially lessening of the working load, was necessary to prevent occupational low back pain, and that it was the most helpful effect on their low back pain to take a rest on and after the attack of the disorder, while most of the medical treatment without a rest were almost helpless.
    In this report, the author studied and discussed on the workers' opinions on the ways to prevent and to treat their low back pain, by means of questionnaire-method. The workers examined were classified by whether they had the disorder or not and also by the grades of their working load.
    The results are as follows :
    1. As for preventive measures, it is the most popular opinion that they should take care not to hurt their low back; nevertheless, as a matter of fact, their low back pain has been mainly resulted from overwork.
    2. As for necessary means on the attack of low back pain, many workers believe that medical treatment is the most helpful to the disorder. Fewer workers recognize the low back pain as an occupational disorder and have opinion that they should take a rest on the attack of the disorder.
    3. There is much discrepancy between the workers' opinions mentioned above and the occupational health doctors' recommendations that it is most desirable to improve the working conditions and to let the workers take a rest.
    4. The more seriously they suffer from the disorder, the more practical and reasonable are the contents of their opinions.
    5. In order to let these workers take a rest from labour more easily, the employers should recognize their low back pain as an occupational disorder, including offjob-payment.

    現在振動病診断に利用されている冷水浸漬試験は多くの場合5℃の冷水に片手を手関節まで10分間浸漬し, 手指の皮膚温反応をみるという方法が採用されている.しかし, この方法では, 被検者に与える苦痛も大きく, 時として, 試験を中止せざるをえない場合も生ずる.そこで, 被検者の苦痛を軽減し, しかも検査精度を大きく落すことのない方法として, 10℃冷水10分間浸漬法の有効性と苦痛の程度について検討を加えた.
    学生16名および振動病患者29名について, 水温5℃と10℃の二種の浸漬試験を行ない, 手指皮膚温反応を検討するとともに試験中の苦痛について五段階自己評価法によりその経過を調べた.その結果次のことが明らかとなった.
    1) 10℃法における浸漬中止後の皮膚温の回復傾向は5℃法における回復傾向と有意の相関を示した.
    2) 検査精度からみれば, 浸漬中止直後の3分間の回復傾向で評価すれば, 10℃法も有効である.とくにrecovery activity (回復能) とrewarming rate (3分間皮膚温平均上昇率) とには, 学生と患者との間に有意差がみとめられて, 指標として利用できる.
    3) 苦痛についての自己評価では, 学生も患者も10℃法のほうが5℃法よりも苦痛が軽かった.苦痛のうち, 胸のしめつけ感は学生よりも患者のほうがより強く訴えた.
    以上の結果から, 10℃法でrecovery activityないしrewarming rateを指標とするならば, 検査精度を大きく落すことなく, 被検者の苦痛は軽減できることが明らかとなった.

    Structures of Cornell Medical Index and Medical Data Index were examined by factor analysis. Both of the translated questionnaires were self-administered by six hundred male employees. Questions of low response rate less than 5 and 6% were excluded, and 117 and 70 questions were analysed finally by the method of varimax rotation for CMI and MDI respectively.
    Ten factors were extracted. Cumulated contribution ratio of them amounted to 72.0 and 84.1% for CMI and MDI respectively. The first two factors were common for the both questionnaires and had pronounced contribution ratio amounting to 36.7 and 29.3% for CMI and MDI respectively. The first factors was composed of questions related to autonomic inbalance, gastrointestinal symptom and fatigue, so it was named a tendency of many physical complaints. This factor was considered to be characteristic and representative one in such general health questionnaires, which was closely related to response set of the respondent. The second factor of the questionnaires was named mental instability.
    The two major factors would correspond to the first and the second component of the Subjective Fatigue Complaint Test (1970) by Japan Association of Industrial Health. Not also CMI but MDI were found to have a poor scalability except for the two major factors.

    It is well known that the small intestine of mammals can transport calcium actively from the mucosa surface to the serosal surface. Wasserman and Taylor have purified a protein from chick intestinal mucosa which binds calcium and is thought to be related to calcium transport. It was proven by the technique of the fluorescent antibody that this calcium-binding protein (CaBP) was localized in the brush border and Gobblet cells of the intestinal mucosa. Sugawara demonstrated that the binding activity of the CaBP obtained from the rats administered cadmium was lower than that of the rats unadministered cadmium. In an attempt to approach the effect of cadmium on the intestinal brush border, the calcium binding activity of mucosa protein and the activity of Mg2+-stimulated and Mg2++Ca2+-stimulated ATPase (ATP phosphohydrolase, EC 3.6.1.3.) and alkaline phosphatase (orthophosphoric monoester phosphohydrolase, EC 3.1.3.1.) in the brush border were determined.

    作業現場における有機溶剤気中濃度は, 時間的, 場所的に著しく変動する. したがって作業者の健康管理を適切に行なうためには, 暴露量を作業者個々の作業時間, 形態に応じて測定する必要がある. このためには, 個人サンプラーは有効な方法の一つであり, 簡便かつ正確なサンプラーの開発が期待されている. 今回は, Feldsteinらが示した, silica gel 吸着-dimethylsulfoxide (DMSO) 抽出脱着法に基づき, 関らの silica gel 部分冷却方式を応用した小型サンプラーを試作した. この装置について, 通気速度と連続使用可能時間, 水蒸気除去剤の検討, 溶剤蒸気の回収率についての検討を行ない, 良好な成績を得たので報告する.

    It was previously reported that rejoining of radiation-induced chromosome breaks was inhibited by benzene in vitro. Benzene is known to be metabolized quickly in the tissue into some of phenols, among which phenol is the most predominant metabolite. In the present study, therefore, phenol was tested on its inhibitory effect on rejoining of radiation-induced chromosome breaks in cultured human leukocytes by the use of dosage fractionation method.
