Time distribution for daily works was studied on 131 firemen at Yotsuya, Kojimachi and Arakawa fire brigade stations in Tokyo as well as their energy expenditure calculated from R. M. R. The results showed that the average energy consumed per head per day was 2550 calories, which is not always adequate for their heavy works. Of the three brigades, Arakawa's firemen consumed the most calories. When compared this energy expenditure with calory intake, the latter was higher than the former, but, for those of the everyday duty, their calory intake was not satisfactory considering from the status of digestion and absorption of Japanese.
Milk was mixed with 8% of skimmed milk powder and 8% of cane sugar. Then their solution was filtered and pasteurized at 85°C for 30 minutes and kept cooled. The treated milk wasused, 3% of the mother starter of the lactic acid bacillus was added to it and kept at 37°C for 8 hours for fermenting. The mother starter is fermented milk whick lactobacillus bulgaricus 1 part and Streptococaus lactis 4 parts were mixed. In non-fortified yoghoort experiments the method mentioned above was practiced, while in the 1st fortified experiment vitamin B2 was added, in the 2nd expt. both B1 and B2, and in the 3rd expt. B1, B2 and Ca-lactate were added. The increase and decrease in vitamin B1 and B2 contents were analysed before and after the fermentation of those yoghoort products.
Biometry and measurement of basal metabolism were conducted on 91 healthy men and women aged 61 to 86 years. Results obtained were as follows 1) Morphological characteristics of the aged were inferiority in the circumferances of arms and thigh, but superiority in the circumferances of abdomen and knee-joint. Both DuBois' “height-weight formula” and “linear-formula” in calculation of the body surface area gave almost the same value even in the aged. 2) Basal metabolism per square meter per hour of the aged were 34.0 Cal. for men and 33.7 Cal. for women, which showed a very little sexual difference. 3) Calorie intakes of the aged amounted to 1780 Cal. per day for men and 1470 Cal. for women, which were nearly 10% less than the Japanese dietary allowance, because of their lighter activity.
Our former experiment has proved that amylase of copra meal Koji was considerably inferior to that of wheat bran Koji, but its protease was much superior espicially in peptonization. Amylase of Koji manufactured by mixing rice bran or wheat bran with copra meal at various ratios has approximately the same as that of wheat bran Koji, but protease was superior to that of wheat bran Koji, as far as exist copra meal. In this report, amylase potency of the various kinds of copra meal Koji manufactured by adding starch and sugar materials to copra meal has been measured. This experiment showed that amylase potency of the copra meal Koji has been increased by adding starch and sugar materials to copra meal. Especially in sugar maltose was superior to glucose.
There are numerous, about Calcium content in white rice. Calcium content of white rice are distributed thus, somewhat due to the differences of soil condition, fertilizer, kind, rice-hackle, mix up. But I think that the general situation of the content exist surely. Calcium is analysed by the gravimetric method. There are two-, Calcium gravimetric methods. The one is washing Ca(COO)2-H2O ppt. by 0.1% (NH4)2(COO)2, and the other is washing the ppt. by hot water. So, investigated the dissolving Ca(COO)2-H2O ppt. by hot water. The results are as follows: (1) In the Calcium gravimetric analysis of randomized 17 samples, Calcium contents of the rationed rice are concentrated near 9mg/100g. (2) There are no difference analytically, between two Calcium gravimetric methods.
To examine the influence of the confinement on the body function and nutriture, basal metabolism, body weight and blood pressure were measured on 4 healthy prisoners from 7th to 22th of April, 1953. Results obtained were as follows: 1) Basal metabolism depressed about by 5.3% after the 11 days of confinement. 2) Body weight was also decreased by 2.6%. 3) Blood pressure showed an apparent decrease by 8-9%. 4) It was confirmed, consequently, that the activity of body tissue was depressed by restriction of physical exercise even when the nutritive foods were supplied.
To examine the influence of the confinement on the body function and nutriture, basal metabolism, density of whole body, nitrogen balance, creatinin in urine, specific gravity of blood, strength of grip, and blood pressure were pleasured every morning on 5 healthy prisoners for 33 days. Results obtained were as follows: 1) Basal metabolism decreased by 10% after 20 days of confinement. 2) Body weight showed 2.5% of decrement too. 3) The change in the body density was not seen during confinement. 4) The subjects having higher body density showed higher basal metabolism rate. The basal metabolism has a close relation with the body density. 5) The function of blood circulation was depressed after confinement. 6) The depression of the function and nutriture above mentioned were completely recovered after a week of an adequate physical working.
