JOURNAL FREE ACCESSThe following preparation of mold pericle was found to be fatal to the test animal rats.: Surface culture of Penicillium rugulosum and Penicillium tardum on czapek's medium, 50 and 25 gram of obtained pericle dried at 55 to 60°C being mixed per 1 kirogram of basal diet. Both the strength of toxicity resulted the decease of test animal within 10 to 52 days.
The main cause of death is found to be kidney disease.View full abstractDownload PDF (5202K) -

JOURNAL FREE ACCESSIn a country long and narrow compared with its area such as Japan, there is a tolerable provincial difference in external temperature between the Northern region and the Southern region. It must therefore be natural to consider that external temperature difference has effects on the basal metabolism (BM) of the population.
Though we have already reported that the seasonal BM has a close relation with external temperature, there still remains room to doubt whether a completely identical relation such as this can exist in regional climate difference, because in cold and warm regions clothing and heating, i. e., artificial climate conditions differ; besides this, the individual difference of exposure time to such artificial temperature must also be considered.
Taking winter for example, heating conditions are satisfactory in the Northern region and people spend more time of their every-day life indoors. While in the Southern region though the external temperature is not exceedingly low, room temperature is almost equivalent to external temperature as heating conditions are unsatisfactory and people are under the influence of external temperature all day long.
From this point of view, we have carried out BM observations on personnel of the Self Defence Forces since 1950, a total of 1453 persons in number, selected through out the country mainly in summer and winter. These men were selected as subjects for the reason that they are scattered all over the country and also because their labor and other living conditions are identical.
Results of BM measurements are presented in the next table and figures: Table shows each value; Figure 1 localizations of subjects; Table 2 relation of external temperature and BM of entire subjects; Table 3 relation of external temperature and BM of infantry corps only, dots in the figures indicate average BM values of each region.
From these data the following tendency is evident:
1. BM values are in reverse proportion to external temperature.
2. BM has a tendency to increase abruptly with temperature-decrease till 10°C attained. At temperatures above an increase of approximately 5% for each 10° is observed with temperature-decrease.
At temperatures lower than 10°C this inclination declines. There is a 1-2% BM increase with a 10° decrease in temperature.
This trend mentioned above is completely reverse to naked-cold exposure in an air conditioned room. This may he attributed to protection from cold by means of heating and clothing and spending more time of their everyday life indoors in Northern region.
Observing the entire temperature range there is an apprx. 2.5% increase in BM values for every 10°C decrease in temperature, this coefficient being almost in consistence with seasonal variation.View full abstractDownload PDF (5520K) -
On the Correlation of Carotene and Sugar Content of Sweet-Potatoes StoredS. Innami, T. Kuga, K. Matsuzawa1958 Volume 16 Issue 6 Pages 179-182

JOURNAL FREE ACCESSCarotene is special component in sweet potato. It is proved that carotene and sugar content increase during the period of storage. Then, the correlation between the content of carotene and sugar content in Yo No. 7 after five months storage was investigated.
As shown in table 2 and Figure 1, 2, 3, 4, 5, negative correlation coefficients between carotene content and specific gravity, carotene content and starch content were the significant difference at the 5% probability level.
But correlation coefficients between carotene content and other sugar content; reducing, non reducing and total soluble sugar content; were not significant statistically at the 5% probability level. From these results, the tubers rich in carotene are smaller in starch content and in specific gravity than those poor in carotene.View full abstractDownload PDF (4319K) -
Effect of Corn Oil and ButterT. Tezuka, S. Oshima, S. Suzuki1958 Volume 16 Issue 6 Pages 183-186

JOURNAL FREE ACCESSSeveral foreign authors have reported that serum cholesterol level was lowered by the intake of vegetable oils and elevated with animal fats. But these experiments were all carried out on Americans and Europeans whose serum cholesterol levels were much higher than Japanese.
The serum cholesterol level of Japanese adults mostly lies between 140mg/dl and 200mg/dl, though the mortality due to cerebral haemorrage accompanied by hypertension and atherosclerosis has recently become the highest among all causes of death in Japan.
We studied, therefore, the influence of corn oil and butter fat on the serum cholesterol of Japanese.
Seven subjects were devided into 2 groups and the experimental period was 18 days long for the 1st period and 12 or 19 days for the 2nd period. In the 1st period the one group took corn oil and the other butter fat. The amounts of lipids ingested were decided to such degrees that one third of the total calorie intakes were supplied with them. In the second period, the sort of lipids were changed for each other.
The serum cholesterol level of No. 1 group dropped from 216mg/dl to 181mg/dl in the corn oil period and rised to 297mg/dl in the butter period. In the No. 2 group, the increase of serum cholesterol by butter was from 177mg/dl to 240mg/dl and the decrease by corn oil was from 240mg/dl to 162mg/dl.
The serum lipid phosphorous level also changed almost in parallel with cholesterol.View full abstractDownload PDF (5048K) -
On the Muscle Power of Blind School-children (Part 3)Tokuko Sato1958 Volume 16 Issue 6 Pages 187-191
Published: 1958
Released on J-STAGE: October 29, 2010
JOURNAL FREE ACCESSComparative studies are made on the muscle power of blind and normal school children (9-20 age) in 3 prefectures of Tohoku district, and the following characteristics are found.
Power of shoulder and arm muscles (measured by a special instrument designed by Prof. Kondo) and especially backmuscle-power of blinds are inferior to normals'. In the indices of both muscle-powers to their body weight, blinds are more inferior to normals than in their absolute power, therefore it seems that blinds' muscle power is relatively week to their physical conditions.View full abstractDownload PDF (5648K) -
The Essential Amino Acid Intake Calculated from the National Nutrition SurveyNobuo Matsuno, Ayako Nishihara1958 Volume 16 Issue 6 Pages 193-198

JOURNAL FREE ACCESSAn evaluation of the essential amino acid intakes was calculated using the data of the National Nutrition Survey in Japan, to find out the actual intake of the essential amino acids by Japanese people.
The results showed the amount of intake of lysine and methionine was higher in urban than in rural. Though in both area the intake of sulfur containing amino acid and tryptophan was low compared with the provisional protein. Tryptophan being 73%.
When comparing the yearly intake of essential amino acids during 1946-1956, a yearly increases of leucine, isoleucine, lysine, methionine and threonine was seen per gram of nitrogen, but no change in phenylalanine, tryptophan and valine was seen.View full abstractDownload PDF (7455K) -
