The author made series of study on the mode of living of students in certain evening senior high school in Tokyo. The results obtained are reported in the following two chapters. Chapter I. In this chapter the author made an investigation on the daily life of evening school students in order to make the status quo of their life clear, and understand the nature of problems resulting from the status. The author also tried to find solutions of the problems so as to improve the system of education in evening school. 1) The daily life of evening school student presents a marked difference from that of day school students. The difference may mainly be resulted from the fact that the most of evening school students engage in their day-time jobs. Time available for rest, recreation, reading and other extra-curricular activities must be quite limited in case of evening school students compared to that of day school ones. 2) It was estimated that only 54% of freshmen were able to finish the four-year full course, namely the rest of freshmen left school on a half way of the course. This may be said as a special phenomenon in evening school and this matter may cast one of the serious social problems. 3) Not a few students are absent or late in class because of their day-time jobs. As many as 47% of the students are listed on the record of disease and injury. 4) About 90% of the students have jobs in the daytime. Twenty-one per cent are engaged in heavy work according to their subjective description. This fact must seriously be considered for the sake of successful evening school education. 5) The monthly income is 5, 000 yen on average and about 40% of the amount supports their tuition and other school-expenses. 6) An examination on the degree of their fatigue clearly indicates that the type of fatigue is not physical but rather volitional or emotional one. 7) An examination of menstruation of evening school girl-students indicates that amenorrhea is prevalent compared to day-school girl-students. 8) As regards their family life, the number of inmates per family is 6.8 persons and this means a greater rate than in case of day-school students. 9) In regard to their sleeping-hours, many of them go to bed later than 11 o'clock in the evening and their sleep is naturally unadequate compared to that of day-school students.
In this chapter the author made a research on the physical condition of eveningschool students, especially in the light of physiological function. 1) In respect to their physical growth, it was found that they are short with an unproportionately long trunk. 2) It was found that they have a small vital-capacity of the lung and a weaker eye-sight which is one of the most marked physical signes of evening-school students. 3) Results of the examination of their motor fitness show that on all the items taken up for the examination they are, more or less, inferior to day-school students, particularly in equilibrium, endurance, and their circulatory and respiratory performance. 4) Blood-examination is very important for evening-school students as one of the effective methods for their health-supervision. It helps to discover students in ill-health which could not be checked either by X-ray examination or physical measurement carried out once a year. 5) A type of screening method was adopted for the purpose of mass-examination of the blood. 6) The hemoglobin-level of evening-school students is 15.26 g/dl (in boys) and 13.64 g/dl (in girls), showing a lower level than those in day-school students. The change of their hemoglobin-level in the recent five years, is pararell to the change of economic situation of Japan in general, but is should be noted that the hemoglobin-level is found lower than that of gerenal Japanese population. 7) The measurement of specific gravity of the whole blood (Gb) is equally important for the health-supervision of evening-school students. In fact, it is re-vealed that 10-30% of the students showed anemic findings. 8) Nutrition is also supposed to be one of the most important factors in solving the health problems of evening-school students. Those who have anemic tendency are especially present among the students of the lower-calory group. The average a mount of calory taken by evening-school students found as 2387 Cal/day (in boys) and 1879 Cal/day (in girls). 9) As regards the students of the lower-calory group, it was discovered that the amount of wheat, fish, milk, eggs, fat and sugar taken by them is markedly reduced, and that their meal-time is considerably unsettled and irregular. Regarding meal-time of evening school students, it was observed that the neareg to the week end, the later is the suopertime,
Using driving wheel, the author tested the effect of olfactory stimulation ofiso -butanol and -iso-amylalcohol on the general activity of inbred strain of Swiss albino mice, CFW, DDd, and Na-2. In general, iso-butanol was more effective than iso-amylalcohol, and showed the ensitive strain was CFW.
As to 6 diabetic patients whose blood sugur levels were found above 140 mg/df by urinary-screening examination of a farm village (Naguri Mura, Saitama Prefa. cture), We gave them calcium mesotartrate by mouth for three months (daily dosis 3.0 g or 7.2 g), and observed the change of their blood sugur levels. As one of them died during the period, the result was not known as regards with him, but among the rest, 3 case down to 140 mg/dl and their urine sugur was almost diminished. As to the remaining 2 cases, which had evidenced hyperglycemia (40) 600 mg per cent), we got a very favouable result from the point of their blood sugur. When a patient takes above 7.2 g of calcium mesotartrate a day, the effect is remarkable, but if 3.0 gr or so a day, the influence to blood sugur is rather small. It is considered, therefore, more resarches will be necessary concerning the quantity and method of administration of calcium mesotartrate as effective chemicals for diabetes..
