Report I. Socio-economic Condition As the Background of AnemiaNaohisa OKADA, Noriyuki NITTA, Hiroyuki NAGAMI, Ryotaro SEKI, Yosuke Y ...1973 Volume 21 Issue 5 Pages 471-478

JOURNAL FREE ACCESSToday, rural communities in Japan are on the brink of a ruin, and the rapidly deteriorating social conditions there have exerted a harmful influence on the health of farmers.
During the work for protecting health of the inhabitants in a village of Ehime Prefecture, it was noticed that a considerably low level of community health has reflected on the high frequency of anemia.
It is noteworthy that most of the anemic cases result from overwork and unbalanced nutrition caused by poverty.
In our last investigation on 1389 inhabitants, anemia was found in 28.0% of the male adults, 25.7% of the female adults, 40% of the old people. The mean hemoglobin level was 14.58±1.63 in the male adults, and 12.57±1.51 in the female adults.
It is urgently necessary to take effective measures to correct the situation.
As causal factors, we can enumerate distorted dietary life, overwork, and physiological phenomena peculiar to women, such as pregnancy and delivery, in the case of women; and overwork, a general decline of bone marrow functions, and the secondary anemia caused by other diseases in the case of old people. The establishment of a system of community health control is needed more than anything else.View full abstractDownload PDF (920K) -
Report II. Blood Conditions of Pupils and the BackgroundNaohisa OKADA, Noriyuki NITTA, Hiroyuki NAGAMI, Ryotaro SEKI, Yosuke Y ...1973 Volume 21 Issue 5 Pages 479-483

JOURNAL FREE ACCESSAn examination of anemia has been carried out for 466 pupils of Aiji Elementary School and Aiji Lower Secondary School in Hiromicho, Ehime Prefecture.
The cases of anemia became more and more frequent as the age of the pupils advanced, and this, we think, is closely connected with the distorted dietary life which is forced upon the people in rural areas in Japan by the repid change of living conditions there.
For measures to counter the frequent occurrence of anemia among pupils it is most important to establish a close cooperation between the school health protection and the community health protection and to pursue the community program of health protection.View full abstractDownload PDF (2548K) -
II. Survey on the snailsNoriji SUZUKI, Shigehiro OZU, Chujiro AIDA, Shinichi TAKEI, Shozaburo ...1973 Volume 21 Issue 5 Pages 484-490

JOURNAL FREE ACCESSAn endemic dermatitis of unknown etiology has occurred among farmers working in paddy fields in the eastern area of Saitama Pref. In view of the results of the epidemiological and clinical observations, it was anticipated that the dermatitis might be caused by a bird schistosome (Ozu et al., 1972).
Thus, the research for snail intermediate hosts was carried out in the paddy fields as well as in the laboratory. Snails from the fields were placed in containers in which they could be checked for the shedding of cercariae. As a result, a species of furcocercous cercaria was obtained from Austropeplea (Lymnaea) ollula. The cercaria was identified as species belonging to the genus Trichobilharzia on the basis of the flame cell pattern, the behaviour, the responses to light and the detailed morphology of living and preserved specimens.
In order to determine the dermatitis-producing properties of the cercaria, an experimental infection with the cercaria into the human skin was performed.The cercaria invaded into the human skin and produced a dermatitis quite similar to that prevailing in the endemic area.
On the basis of the results from this study, the paddy field dermatitis occurring in the eastern area of Saitama Pref.was proved to be caused by the invasion of the cercaria belonging to the genus Trichobilharzia into the human skin.It was also proved that A.ollula served as the snail host of the cercaria.View full abstractDownload PDF (3551K) -

JOURNAL FREE ACCESSA dermatitis of unknown etiology has occurred among farmers working in Chichibu City, in north-west of Saitama Prefecture from 1970 to 1972.
The dermatitis exhibited clinical, manifestations quite similar to a already known bird schistosome.dermatitis being characterized by erythemato-papulo-vesicular eruptions accompanied with severe itching on the parts exposed to the water, especially legs and arms.
Survey on the snail intermediate hosts were undertaken in the paddy fields and a species of furcocercous cercaria was found from Polypylis hemisphaerula.The incidence of the snails infected with the cercariae was 3.2%.The cercaria resembled to that of Gigantobilharzia struniae in size and shape.
The cercaria invaded into the human skin within 30 minutes after being put on a part of the surface of skin and caused a pinpoint-sized red maculae and tingling itching.
From these results, the paddy field dermatitis occurring in Chichibu City was proved to be caused by the invasion of the cercaria into the human skin, which differed from that served as causative organism of the dermatitis occurring in the eastern area of Saitama Prefecture.View full abstractDownload PDF (5526K) -
Examination of the Ticks, Ixodes nipponensis Parasitic on Man through a Scanning Electron MicroscopeYousuke YAMANE, Ryo HATSUSHIKA, Sekiya MINAMI1973 Volume 21 Issue 5 Pages 496-500

JOURNAL FREE ACCESSWe used a scanning electron microscope for identification of the two ticks which were found parasitic on two women.
(1) The patients were women of 69 and 62 years old.The main complaints were a tumour-formation on the skin of the upper abdominal region with itching in one case and the pain at the cicatrice of a past operation of the chest in another.In both cases a purulent inflamation appeared after 7 to 10 days at the site of bite and healed after 10 to 14 days with pigmentation.
(2) In our study through a scanning electron microscope we examined the morphological characters of marginal body setae, porose area, internal as well as external spurs of coxa I, and genital pore. The scanning electron microscope was effective especially to observe marginal body setae, spiracular plate, and internal as well as external spurs of coxa I, which are important for discriminating Ixodes nipponensis from Ixodes persulcatus.
We would expect that the morphological and physiological study of Ixodes species will develop hereafter concurrently with the parasitism of man by Ixodes nipponensis from the epidemiological standpoint.View full abstractDownload PDF (6776K) -

JOURNAL FREE ACCESSThe auther investigated a few points in the controle for cardiovascular diseases in rural areas.
The results can be summarized as follows;
1) Many of the examined had been taken their blood pressure for the first time, and many suffering from the hypertension had not known that they were hypertensive.
2) It seemed that the response rates to the examination were influenced not by the staff of the examining team or the content of the examination, but by the duration of the examination or the number of the places offering it.So the method and the content of the examination should be settled according to the circumstance of the areas.
3) The health consultation should be started with the mass examination, and be offered continuously after it.
It is indispensable to give the health education to their family.View full abstractDownload PDF (821K) -

JOURNAL FREE ACCESSToday, many villages in Japan are rapidly declining as a result of the policy of the Japanese government aiming at the growth of monopoly capital.
Shimo-Ono is one of such villages, with 184 houses and 731 inhabitants. We would report the progress of the regional examinations carried out in this village for these nine years and discuss about the necessity of the communal system of health protection, the actual state of health destruction and the countermeasures to be taken against this, and the problems imposed upon future regional examinations.View full abstractDownload PDF (1394K)
