ジャーナル フリーWith the primary purpose of analyzing the biological and socio-environmental factors related to the premature and immature-birth, the author carried out the investigations from June 1958 to May 1962 on the pregnant women who visited the Kyoto National Hospital.
Investigations were made on a sample of 1052 subjects by means of interviewing three times during their pregnant period.
Statistical studies were pursued on various kind of factors which would influence the premature and immature-birth such as physical and mental fatigue, nutrition, school career, prenatal medical care, family income, etc.
The author noticed that economical state of home life responsible for the overwork and insufficient nutrition of the pregnant women will be the most effective factor.
The detailed results obtained from these surveys and analyses are reported and are shown in Tables 1∼34.抄録全体を表示PDF形式でダウンロード (2717K) -

ジャーナル フリーIt has been mentioned by many investigators that the infective larvae of Ancylostoma duodenale can easily come to maturity in human hosts by per stomachic infection, however, those of Necator americanus are scarecely possible to develop through the stomach.
In this study reported here, experimental infections through the stomach were carried out to 5 volunteers, without history of previous hookworm infection, for the purpose of making clear the main infection route of hookworms to human bodies and the cause of the difference of infectivity between larvae of Ancylostoma duodenale and those of Necator americanus in the stomachic infection to human hosts. Furthermore the larvae used in this study were not simply infective larvae, but were larvae that still stayed in ratskins for 24 or 48 hours.
But in this investigation, though larvae of Ancylostoma duodenale succeeded in the infection, those of Necator americanus failed. From this result, the auther guess that the establishment of stomachic infection to human hosts with larvae of Necator americanus is very difficult, and their infection ability can not increased from staying in ratskins. When the larvae migrate in human bodies, the auther imagines that it is necessary to pass through the lunge for accomplishment of infection.抄録全体を表示PDF形式でダウンロード (6104K) -

ジャーナル フリーA study on the differences of blood pressure between right and left arm has been performed for 364 workers who aged over 40 years old in a certain of Heavy Industry Plant, here in Nagoya.
The results were as follows:
1) No remarkable difference of blood pressure between right and left arm of these workers was observed, i.e. there was only 1.7per cent of showing difference in systolic pressure more than 26mmHg (inclussive) between both arms, also 0.7per cent for diastolic pressure.
2) Generally, persons who showed difference of blood pressure between both arms were higher in the right arms than left arms.
3) No correlation was found in the blood pressure between the grade difference of both arms and the girth of upper arms.
4) As a conclusion, it is recommended that the right arms rather left ones be blood-pressure-measured in order to select the hypertensive persons.抄録全体を表示PDF形式でダウンロード (604K) -

ジャーナル フリーPolyvinyl chloride plastics are often made by combining the stabilizer containing lead compounds. In an ivestigation into straws as a representative of the tableware made of this plastic, it was found that straws allowed to be immersed in 4% acetic acid solution for ten minutes yielded from 0 to more than 100μg of soluble lead. Even in water, pH 5.4, straws yielded soluble lead. Under several conditions, an amount of soluble lead from straws were investigated. Among them, pH was found to be a leading factor.
To protect beverages from lead dissolved out of these straws, treatment of straws with acid-washing was found to be most effective and feasible. For surveying these straws, purple color development by immersing them in an acidic rhodizonic soda solution might be well.抄録全体を表示PDF形式でダウンロード (769K) -

ジャーナル フリーFree-glucuronic acid and glucuronides excretion seem to be necessary to discuss toxicity and detoxition mechanism of various chemical substances in animal body. Present report was made with rabbits exposed to toluene, xylene and carbon disulfide in relatively low concentratons. Namely, the concentrations of these organic solvents were 211±19.3ppm in toluene, 209±28.5ppm in xylene and 108±17.5ppm in carbon disulfide respectively. Exposure chambers were designed for dynamic exposure. The time of exposure was 6 hours in all cases of these experiments.
Analyses of urinary free-glucuronic acid and ether glucuronide were made by the naphtoresorcin picrate methods. Both wrs corrected by the concentration of urinary creatinine. Therefore, the value of glucuronic acid excretion in urine was expressed as G/C and OG/C ratio. The following results were obtained.
1) The immediate decrease of G/C ratio in urine was observed after exposure of toluene. The reelevation to pre-experimental level after a cessation of the exposure would be comparatively slow. These responses mentioned above were shown more markedly in summer than that in winter. Also the response of OG/C ratio in urine resembled the change of G/C ratio exclusively.
2) In the case of xylene exposure, the range of increase as to glucuronic acid excretion was from 117% to 129% in G/C ratio and from 121% to 142% in OG/C ratio. Two days after the exposure no increase of glucuronic acid in urine was observed. Metabolites of xylene in animal body would be apparently conjugated with glucronic acid and then eliminated into the urine shortly.
3) Transient decreases of G/C and OG/C ratio were shown after exposure of carbon disulfide as well as that in the case of toluene inhalation. However, they were slight as compared with the decrease of G/C ratio by exposure to carbon disulfide in higher concentration.抄録全体を表示PDF形式でダウンロード (758K)
