ジャーナル フリーAccording to the result of totally 10 time mass-screening examinations of pulmonary tuberculosis carried out annualy twice spring and fall during five years, the following conclusions were obtained.
1) Both the roentogenographically positive finding rate and prevalence rate of actual case had been decreased over a period of five years.
2) Cases of mixed form with exsudative and fibroid lesions, according the Oka roentonographic classification, was most apparently decreased in five years. In the forms of the hardnodular and calcified-scar lesions the rates did not any significant changes, and the form with the deformation by surgical operations increased by the spring 1957 and no change was observed after that. Occurrence of exsudative pleurisy was very seldom.
3) In the classification of guide standard, number of the patients with the A calss (off work required) and the class B (limitted working hour) remarkably decreased, and those of the class C (under supervision) relatively increased.
4) According to the classification by the Japan Society of Tuberculosis, no case with extensively advanced cavity form was found through the observation, and cases with not-advanced cavity form disappeard by the end of the observation. Also cases with the varied non-cavity form was obviously decreased. No apparent changes were shown in the unmber of cases with the stable non-cavity form and the recovered form.
5) The decrease of the number of cases with exsudative form seemed to be more apparent in the group of workers with medium physical work, compared with that group of desk workers. The increase of both the roentogenographically positive finding rate and prevalence of actual case was observed by the older years of age, and the trend was not so much varied through the five year observation.抄録全体を表示PDF形式でダウンロード (1051K) -

ジャーナル フリーAudiometric examination was carried out on 178 workers working in noisy shops of our paper mill, and occupational hearing loss was found out among those workers as briefly mentioned below.
1) The number of workers with abnormal audiometric level (decrease more than 30db) was 31, 17.4% out of the subjects.
2) The abnormality rate increased by aging, and it reached 50% among those of 50 years or older of age.
3) When classified by the lenght of employment, those workers within 4 years and more than ten years were found to include more workers with hearing loss in comparison to those between 5 to 9 years. It was rather dificult to explain this result.
4) When the audiometric level at 4000 cycles per second among the abnormals was analysed, the average loss of decibel increased by aging. By the length of engagement, those of more than 15 years showed the higher loss of decibel抄録全体を表示PDF形式でダウンロード (267K) -

ジャーナル フリーA free travelling clinic for the rurae population was performed over a fairly long period of time in an area of Tochigi Prefecture by the staff of a hospital as a part of its social activities.
The following results were obtained by the examinations of tatally 4, 224 patients in 36 local places during the period of 5 years 1953∼1957.
1. The rate of those examined to the total population in each area varied considerably by the nature of social and geographical locality, being higher in mountain villages and in textiee industry districts than in farm villages and urban districts. It was also higher in the villages of small population, especially in doctorless ones.
2. Among those examined, females were more than males in number and persons over 40 years of age more than those of other age groups.
3. Prevalences of chronic discases such as rheumatism, hypertension and cardiac diseases occupied higher ranks among the diseases found by the examinations.
4. In mountain villages rheumatism, cardiac diseases and hypertension were most frequently observed; in farm villages peptic ulcer and bronchial asthma; and in urban districts hypertension and chronic gastritis.
From the standpoint of treatment and prevention of diseases, such epidemiological study as mentioned above is of worth to continue.抄録全体を表示PDF形式でダウンロード (886K) -

ジャーナル フリー1. Blood pressure measurement of inhabitants of Koiwa Health Center district in Tokyo, was made and hypertension was studied on various professional groups.
2. Lower percentages of persons with hypertension were found among the people engaging in professions concerning public health such as barbers, beauty shop workers, restaurant and the provision shop workers. The reason is considered that they have more chances to receive health education from the health center.
3. A higher percentage of those with hypertension was found among farmers. The dietary unbalance and the excess of labor is considered to be the cause, and further health center activities are desirable.抄録全体を表示PDF形式でダウンロード (741K) -

ジャーナル フリーThe efficiency of man-machine system is influenced by the atmospheric conditions within which the human activities are carried out. One of the important aspect of the environments is that of temperature. Impairment of finger dexterity in various thermal conditions was observed by FD test and tapping rate. A marked drop of finger dexterity was showed at about below 23°C of dorsal hand skin temperature in spite of various outer environmental conditions. This level of the skin temperature was interpreted as additional evidence to the observations that seasonal variations of regional skin temperature, vascular reflex, and insensible perspiration of dorsal hand showed remarkable quantitative and also qualitative changes at about 23°C of skin temperature.
The decrement of manual dexterity is probably caused by some arm circulatory conditions.抄録全体を表示PDF形式でダウンロード (705K) -

ジャーナル フリー蛋白膜を除去した回虫卵を1:2000 Acridinorange中性水溶液に混じて,螢光顕微鏡で観察すると,生卵では卵殼が緑色,稀に黄色或いは橙色の螢光を発するのみで卵内容は螢光を発しないので全く見えない。
然るに自然死した変性卵や種々の方法で殺した虫卵では,卵内容が緑色或いは黄緑色,黄色,橙色,稀に赤色等の螢光を発し,単細胞期,分裂期,仔虫期など,いずれの時期でもその形態が明瞭に認められる。
従って,卵内容の螢光の有無によって卵の死と生を判別できるが,この際用いる螢光顕微鏡装置は高性能のものを必要とする。
著者らが螢光法による虫卵生死判別の信頼度を培養法及びSudan III染色法と比較検討した結果では,煮沸殺卵した材料では3方法とも全卵の死を判定できたが,10%ホルマリン水中に2ヵ月半保存した回虫子宮下部卵では,螢光法で全卵が死像を呈したにも拘らず,Sudan III染色法では染色陽性(死像)のものは僅かに7%に過ぎなかった。
さらに,芥子油,二硫化炭素,クレゾール石鹸水,フェノール,エチルアルコール,亜硝酸ソーダ,硝酸,苛性ソーダ,アンモニア水などをそれぞれ26°Cで作用させた虫卵について,3方法による死卵陽性率を見ると,培養法では1ヵ月後に至り全卵変性し,死と判定されたが(勿論この時期には螢光法でも全卵が顕著な死像を呈した),薬剤作用終了直後に於て,既に螢光法では多くの場合培養法の成績に接近した死卵率を示したのに比し,Sudan III法は極めて劣る成績を示した。
螢光法に於ける虫卵の死像発現の機序については,硝酸及びアンチホルミンを用いて卵殼第1層及び第2層を剥離した材料を螢光処理観察した結果,卵殼最内層の変性如何(死卵では色素透過性となる)が最も重要な役割を演じ,さらに卵細胞の死後変性に伴って発現する自家螢光とが相俟って,前述したような死卵の螢光像が現われるものと考えられる。
なお,Acror処理した死卵々細胞の螢光は,その色調が緑色より赤色へ近づくほど,またその強度が増すほど,細胞の変性は高度であると解される。
螢光法に於ては,生体染色法の手技(生体螢光処理)を用いるので,他の染色鏡検法の如く生卵を障害することはなく,また生卵を死卵と誤認する危険はない。
従来,回虫卵の生死判別法として最も精確と考えられている方法は培養法(卵細胞の発育能の有無による判別)であるが,これは結果判定に長時日(1ヵ月以上)を要するのが欠点で,また薬剤による殺卵試験のときなど,作用させた薬剤を完全に洗いおとして培養することが困難なこともあるので,そのような場合には培養中も微量の薬剤の作用を引続き受けることになり,その結果薬剤の殺卵効果が過大に評価されるおそれもある。また仔虫期卵の生死は仔虫の運動性の有無,仔虫体の変性像の有無等で判別するか,動物感染試験以外には方法がなく,それには高度の熟練が要求される。
この観点よりすれば,螢光法(卵細胞と卵殼の変性の有無による判別)では,変性微弱の場合は生死不明のこともあるが,多くの場合生死の判別が即座或いは早期に可能であり,薬剤の妨害も除き得,仔虫期卵でも容易に生死の像の区別ができるので,螢光法は虫卵生死判定のための有力な補助手段として利用価値の甚だ高い方法であると考える。
即ち,培養法に螢光法を併用すれば,最も迅速かつ精確な回虫卵の生死判別が可能であろう。抄録全体を表示PDF形式でダウンロード (3025K) -

ジャーナル フリーBy the fluorescence microscopy, the auther studied on the relation between the phenomenon of the appearance of autofluorescent granules in living larvae of Ascaris eggs and the maturity of the larvae.
Results obtained as follows:
In the 8-9 days larvae after the formation of embryos, fine granules (0.5-0.9μ in diameter), in which faint yellow autoflurescence was observed, were found chiefly in contact with the intestinal cells. Such larvae increased during 10-13 days after the embryo-formation, and the fluorescence color changed to golden yellow. These autofluorescent fine granules were scattered or standing in lines along the intestinal cells.
On the other hand, by the infection test with mice, it was confirmed that the infective larvae remarkably increased during 8-13 days after the embryo-formation. From the above observations, it was considered that the appearance of yellow autofluorescent fine granules showed the maturity of the larvae.
The infective power got to the peak during 16-30 days after the embryo-formation, and it fell down gradually after that, and the autofluorescence of the granules changed to golden yellow accompanied with transformation to round masses.抄録全体を表示PDF形式でダウンロード (2815K)
