JOURNAL FREE ACCESSExperiments were carried out to determine hygienic merits and demerits of polyurethane fiber foundations in daily use and to evaluate their aesthetic effects on the figure.
The method: Four kinds of underwear, that is, those with foundations smaller than the actual measurements in girth respectively by 5, 10, and 15cm and with no foundations, were worn by four subjects. Various investigations were made and measurements were taken under the given conditions for eight days in summer. Aesthetic effects of foundations on the figure were also surveyed with the subjects in their everyday clothing.
In the present report, subjective observations, clothing climate, and clothing pressure were examined.
Results are as follows:
1. The differences in size among foundations make little difference in subjective symptoms of fatigue.
2. Other subjective observations reveal that the smaller the size, the hotter the wearer feels, and perspiration and a sense of tightness increase. Foundations cause discomfort.
3. Clothing climate-temperature and humidity under clothing-is best when subjects are not wearing foundations. The smaller the size, the more uncomfortable it is, and the differences in size among foundations are noticeable during and after working.
4. When in a squatting position, clothing pressure increases and differences in size are noticeable. In other postures no difference is noticeable.View full abstractDownload PDF (822K) -
Part 2. Effects on Physical Functions and Work EfficiencyNoriko Ikuta1970 Volume 25 Issue 4 Pages 350-355

JOURNAL FREE ACCESSIn the present report, effects were investigated of four kinds of underwear, those with foundations of three different fits and with no foundations, on the subjects' states of fatigue, physical functions and on their various kinds of work efficiency.
Results are as follows:
1. Fricker Test shows no difference in the clothing.
2. A foundation smaller than the actual measurement in girth by 15cm is too tight, considering the subject's mounted pulse at short periods of work and its states of recovery.
3. Regarding kinds of work efficiency examined here, foundations of a proper fit achieve the effect of increased efficiency.View full abstractDownload PDF (806K) -
Part 3. Investigations of the Aesthetic Effects on the FigureNoriko Ikuta1970 Volume 25 Issue 4 Pages 356-359

JOURNAL FREE ACCESSIn the present report, the same subjects as in the previous ones were used. Here they wore everyday dresses (knitted ones) over the same underwear, those with foundations of three different fits and no foundations, referred to in previous experiments.
Aesthetic effects on the figure in a standing posture were evaluated by paired comparison and were shown in quantity.
Results are as follows:
1. Differences in size of the foundations have effects on the physical measurements, especially girth.
2. According to evaluation through sensory test, foundations which are hygienically too tight are not good, as they reduce the aesthetic effects on the figure. Foundations, as long as they are of moderate degree of tightness, heighten the effects.
To sum up the above three reports, it can be said that the proper foundation to be selected is the one which measures 5cm shorter in girth than the wearer's actual measurement. Not only subjectively but also from the standpoint of effects on physical functions, those well-fitting foundations have almost the same satisfactory evaluation as when foundations are not used.
In certain areas, work efficiency is promoted and aesthetic effects on the figure are almost as good as when tighter foundations are worn.View full abstractDownload PDF (459K) -
II. Indirect hemagglutination testSusumu Imamura, Yoshio Ashizawa1970 Volume 25 Issue 4 Pages 360-363

JOURNAL FREE ACCESSAn indirect hemagglutination test using erythrocytes treated with tannic acid and leptospiral antigen was investigated for the detection of antibodies against leptospira. The leptospiral antigen for the hemagglutination test was obtained from sonically disrupted cells of L. icterohaemorrhagiae strain Mikawashima. Anti-icterohaemorrhagiae (Mikawashima) immune rabbit serum and sera obtained from patients of Weil's disease showed positive reactions in the indirect hemagglutination test and non-leptospiral human sera proved negative to this test. Adsorption test of the leptospiral antiserum with the leptospiral antigen was done and the adsorption of the hemagglutinating antibodies was proved. Gel filtration of the antigen was conducted on sephadex G 100 column and the first peak obtained showed activity in the indirect hemagglutination test.View full abstractDownload PDF (557K) -

JOURNAL FREE ACCESSCause of the strange osteomalacia “itai-itai” disease which appeared in the Jinzu River basin, Toyama Prefecture, was concluded to be a public hazard induced by cadmium in the waste water from a mine.
In Annaka City, Gunma Prefecture, where the largest zinc refinery of Japan is located, many samples of agricultural products and soils were collected in October 1968 and June 1969 and analyzed to verify actual conditions of pollution by the refinery.
As a result, it was found that the content of cadmium and other metals in mulberry leaves for silk worm or wheat flour is remarkably related to the distance (220-2, 500m) from the refinery chimney, and further, that the content of cadmium and other metals is remarkably higher in leaf vegetables such as cabbages (Cd 60-3ppm, Zn 7, 000-300ppm, Pb 370-4ppm in dry matter) compared with root vegetables (potato, carrot, radish), fruit vegetables (tomato, squash, eggplant), or cereals (barley, wheat, rice, corn). Nevertheless, the pollution of the latter has to be considered. Thus, it was made clear that principally the hilly regions are polluted by metal contained air, and that lower rice field regions are also affected by polluted air as well as waste water.View full abstractDownload PDF (3057K) -

JOURNAL FREE ACCESSEpidemic of the so-called Itai-itai disease is remarkably restricted within the basin of the Jinzu river in Toyama Prefecture. We have found much evidence that the disease is a form of Fanconi syndrome attributed to cadmium.
In order to determine the time when the Jinzu river water was contaminated by cadmium, investigation has been done on the annual rings of “Sugi” (cryptomeria japonica, a Japanese ceder) near the Jinzu River. For comparison, several stems of the same variety which grow along other river water systems were also investigated.
As to the materials of the Jinzu river, it was found that the width of the annual rings became gradually narrower from the 1910's and narrowest between 1925 and 1943. Their width have become remarkably wider since 1944.
Cd and Zn contents of each annual ring were analysed. They were much higher than that of the controls.
Hence we have concluded that the growth of the trees was suppressed by these heavy metals, Cd and Zn.
Probably under the influence of SO2, these metals dissolved out of the heap of clinkers of the mine factory which is located about 60km up stream from the Itai-itai endemic district on the Jinzu river.View full abstractDownload PDF (2912K) -

JOURNAL FREE ACCESSPhenylmercury acetate was administered subcutaneously to hens for several months consecutively, and these hens were respectively raised in a cage in pair with a rooster, and the rate of egg-laying, the transfer of mercury to eggs and the toxicity of the mercurial on chick-embryo were studied. Egglaying of hen administered with 600μg/day as Hg of phenylmercury acetate was gradually inhibited, and that of a hen administered with 300μg/day as Hg of the mercurial was not inhibited. Mercury concentration in eggs of these hens increased gradually during the period of administration, and after about twenty days of administration reached a stationary state. About thirty per cent of the daily dose of the mercurial administered to hens were transferred into the eggs, and almost all of the mercury in the eggs were found in the yolk. Distribution in organs of hens administered with phenylmercury acetate and in organs of chicken hatched from eggs of the above hens was similar to those of hens and their chicken administered with mercuric chloride.View full abstractDownload PDF (740K) -

JOURNAL FREE ACCESSMethylmercury chloride, mercuric chloride and phenylmercury acetate were respectively administered subcutaneously to roosters with 600μg/day as Hg for several months consecutively, and each of these roosters was raised in a cage with a hen. The rate of hatching from fertilized eggs of a hen mated with a rooster which was administered with mercuric chloride was significantly inhibited as compared with the rate of hatching from control eggs. However, rates of hatching from eggs of hens mated with roosters administered with methylmercury chloride or phenylmercury acetate were not significantly inhibited.View full abstractDownload PDF (557K) -

JOURNAL FREE ACCESSDeterminations of the diurnal and nocturnal 17-Ketosteroids excretion in the urine of two male adults were made every day for 2-3 years.
Seasonal variations in 17-KS excretion were different from the data which had been so far reported by some authors in Japan, i. e., in the two subjects, the peaks were in May to July and in March respectively, not in the winter months. This may be partly explained by the difference in regional climates and by variations of heating and cooling device.
Effects of individual meteorological factors, such as temperature, humidity, air pressure and precipitation, on the urinary 17-KS excretion were slight when seasonal variations were excluded. The integrated effect of these factors, the weather, played a major role in the 17-KS variation.
The level of the 17-KS was lower on fine days and higher on rainy days with medium values being obtained on cloudy days.
Relationship between weather changes and 17-KS excretion is obvious: a decrease of the latter is associated with improvement of the weather and an increase with worsening of it.
It is assumed that the dynamic change in the integrated effect of meteorological factors is more important as a stimulating agent of the pituitary-adrenal system than any individual factor or the effect of a static weather system.View full abstractDownload PDF (5731K) -

JOURNAL FREE ACCESSThe indirect hemagglutination test using tanned formalinized sheep erythrocytes was investigated for serodiagnosis of leptospirosis. The leptospiral antigens for the hemagglutination test were extracted with sodium deoxycholate. Sera obtained about the 2nd week of leptospirosis had positive hemagglutination titers of 1:12, 800 or higher against five leptospiral types, and most sera from healthy individuals and syphilitic sera did not agglutinate at 1:100. The antigens extracted with sodium deoxycholate remained serologically reactive for at least one year when kept in aqueous suspensions at 4°C. The test was observed to be a useful diagnostic procedure.View full abstractDownload PDF (912K)
