Surface area of 201 Japanese (both sexes) from infancy to old age selected statistically according to sex, age and body shape were measured and the regional rates calculated and discussed.
The results are as follows:
1. There was no difference between either side of the body for any age or sex.
2. The rate of head, face and neck decreased while that of the lower extremities increased with aging.
3. After adolescence regional rates could be differentiated between the sexes. The rates of the thigh of the female were considerably higher than that of the male.
4. Body shape, rate of the head, face and neck the tendency waslowest toward obesity and highest toward slenderness. The rates of the limbs, upper and lower extremities revealed the opposite tendency to the former.
5. These results vary little as compared to other studies done on Japanese. However, compared to a German oran American revealed a higher rate for limbs. The rate was definitely lower for the Westerner.
6. Judging statistically the sublects and methods in this study, the regional rates of body surface described in this paper according to sex, age and body shape are acceptable to be used asastandand for the Japanese people for the study and review of all physical parts.

Various calculation formulas of body surface area are designed by the measured values of body surface area and other physical measurements, e.g. height, weight, chest circumference etc, of 201 Japanese of both sexes from neonatal to old age.
Statistically comparing the formulas, the following three may be used for all ages of Japanese with the slightest possibility of error.
1. Newborn (under 1 year) S=W^0.473×H^0.655×95.68
2. Young child (1-5 years) S=W^0.423×H^0.362×381.89
3. Over 6 years to old age (for general use) S=W^0.444×H^0.663×88.83
(S: Surface area in cm², W: Body weight in kg, H: Height in cm)

Oxygen consumption of liver slices from male Wistar rats was determined three times a day, morning, early afternoon and evening, by means of the Warburg manometric method.
Under the lighting regimen of LD 12:12, light from 7:00 to 19:00, there was observed a circadian rhythm, with a trough at the onset of light and a peak just prior to the onset of darkness. After the inversion of the lighting regimen, i.e. light from 19:00 to 7:00, the phase of Qo₂ and Qo₂ (N) shifted gradually and reached eventually to 180° reversal by four weeks after the inversion of lighting.
Our results suggest that there exists a endogenous periodicity in oxygen consumption of the liver tissue, which is entrained to a light-dark cycle as Zeitgeber and consequently appears as a circadian rhythm.

During construction work of a drive way near Tateyama Murodo (ca. 2400m above the sea-level), a good many, not yet acclimatized, labourers suffered from mountain sickness. To establish reasonable labour conditions for them, we have carried out some basic studies on the physiological responses to high altitude stress. Six healthy male adults were chosen as subjects, and ventilation, oxygen consumption, respiratory quotient, pulse rate and blood pressures were measured, and, as for the control data, those of the same subjects at Senju-ga-hara (ca. 460m above the sea-level) were measured.
The following results were obtained:
1) After a 4-5 day duration at Murodo, the BTPS ventilation and STPD oxygen consumption increased approximately 30% more than at sea-level.
2) After a 1-2 day duration at Murodo, however, the STPD ventilation decreased.
3) After a 1-2 day duration at Murodo, the mean values of RQ ranged from 0.90 to 0.96 at rest.
4) After a 4-5 day duration at Murodo, systolic blood pressure and pulse rate were higher than those at sea-level but the diastolic pressure showed no change.

This report describes the status of health, and industrial accidents of truck transportation service workers. This Socio-Medical study was carried out concerning the health of 1250 workers and the accidents of 715 drivers in 14 enterprises.
Results are as follows:
1) Inclusive of working conditions, wages and working time, long duration work was estimated to be much out of proportion to that of sleeping time, rest and medical service.
2) Concerning subjective symptoms, muscle and joint pain, untoward symptoms of stomach and intestinal distress as well as fatigue were especially noticeable when compared to other forms of employment.
3) On an average accidents rated 2.5 times per driver, and, the worse the working conditions were, the more frequent were the accidents.
As a result, for the health of workers and the prevention of accidents improvement of working conditions is proposed as an immediate necessity.

In the daily life of humans Necator americanus larvae is admitted into the human stomach orally along with food and drink. Although this is a matter of everyday occurrence, few researchers have done analysis or examinations. The author noted this fact and made the following two experiments on the infection mode in the human body:
1. Raw vegetables contaminated by Necator americanus larvae were given to four volunteers, masticated and swallowed. After 15 minutes the volunteers rinsed the oral cavity with 30ml water and drank the water. The following conclusion was reached: Eosinophilie was observed in their blood picture and fertilized eggs were found in the feces, however no one complained of subjective symptoms. By expelling, 3, 4, 5 and 8 Necator americanus were obtained respectively.
2. Raw vegetables contaminated by Necator americanus larvae were given to four volunteers, masticated and swallowed. Immediately after that the volunteers rinsed the oral cavity with 700ml water, spawed, again rinsed the oral cavity with another 350ml water and drank. The following conclusion was reached: Eosinophilie was observed in the blood picture of two out of four volunteers, fertilized eggs were found in the feces of one volunteers were free of subjective symptoms. By expelling, 2 Necator americanus could be found.
