A Study on the Free Amino Acid Levels in the Plasma and Erythrocytes of Rats Fed by Rice Diet
Kim, Sung-Ro ; Lee, Hyun-Ki ;
Journal of the Korean Society of Food Science and Nutrition, volume 5, issue 1, 1976, Pages 1~9
The variations of growth gain and the composition of free amino acid levels in plasma and erythrocytes of young rats(wistar strain male) were determined by microbioassay method, feeding diets of rice group and 7% casein group as a control for three weeks. The results were as follows; 1. The growth gain of control diet group was higher than the rice diet group. 2. The contents of free tryptophan, lysine, and threonine levels in plasma and erythrocytes on rats of 7% casein group were higher than the rice group. 3. In the 7% casein diet group and the rice group, these free amino acids were included more in erythrocytes than in plasma. 4. Therefore, generally feeding by high protein score diet was included more Try, Lys, Thr in plasma and erythrocytes than feeding by low protein score diet. So the high and low of protein score was assumed by the contents of Try, Lys, Thr in plasma and erythrocytes on rats.

A determination of proper maturity is a significant factor for a good quality and storage. This study is aimed at a determination of optimum harvest date related to a decisive measuring of maturity in Spur Golden Delicious. In this case, respiratory status and other characteristics are taken as a indicator for maturing determination. The results are as follows. 1. Respiratory rate has been decreased through a fruit development and come to its minimized point on Sep. 25. at last. On the contrary its tendency has been increased after Sep. 25. It is also estimated that the former is pre-climacteric, the latter climacteric rise based on dimacteric minimum Sep. 25. 2. A flesh hardness has maintained comparably high value until Sep. 18. But in the point of climacteric minimum, Sep. 25, curve of flesh firmness has rapidly been broken down, and after Sep. 25, tendency has slowly decreased at the sucessive date. 3. Pectin content, optimum acidity are remarkably decreased after Sep. 25, Oct. 2 respectively. 4. When water soluble sugar content shows to be swung from climacteric minimum, any resonable tendency are not found. 5. In this experiment, optimum harvest time is found by Oct. 2, in time of 145 days after flowering.

The Study for the State of Nutrition & the Development of Physical Standard of Nursery School Children
Lee, Geum-Yeong ;
Journal of the Korean Society of Food Science and Nutrition, volume 5, issue 1, 1976, Pages 31~37
1. In order to increase our physical power through raising the amount of Hb to normal level and thus enrich our national power, it is earnestly required to improve the general eating habits in the direction of taking enough animal protein (nutrition food) that is required to form Hb and adequate administrative procedures of the nursery school are to be taken at the same time. 2. The genetic amentia's development of skeleton is generally under the normal level. And so their physical condition should be inferior to the standard growth rate of the same age. But the fact is that their physical growth is almost the same as the same age with only few exceptions. Besides, considering the fact that their amount of Hb is less than that of the normal level, I think we can conclude that the majority of the amentia in the nursery school were malnutrition during their prenatal period or during their infancy. We need continuous statistical study concerning many amentia that is scattered all part of our country, to make our amentia's hereditary transmission and the expression clear. And so the Intelligence Quotient of the amentia are from 26 to 80, we consider to need nourishing meal in ordinary times to make more efficient development of intellectual faculties. 3. As to the relation between blood type and disease, there are much debates going on in many countries. To get more apodictic results, however, continuous study is desired to be made in the future.
The Effects of the Nutrition in the Boyhood upon the Improvement of the Body in Various Regions
Lee, Geum-Yeong ;
Journal of the Korean Society of Food Science and Nutrition, volume 5, issue 1, 1976, Pages 39~51
We arrive at the conclusion as follows as for the connection between dietary life, hours of exercise and growth of body, based on the survey of their height, this circumference of the breast and their body weight, and the questionnaires to the pupils of 36,547 in totals (contained the primary and middle school boys and girls) in four districts(named A, B, C and D district) of Jeonlla Bug Do from April, 1970 to March, 1973. (1) The growth in height. The boys from 6 to 7 years old are nearly same in all districts, but as age increases, those of A district grow more rapidly than those of B, C and D districts, while those of B, C and D districts grow almost samely. The girls already from 6 years old on are different between A district and B, C, D district. The average of height in Jeonlla Bug Do is not different from that of Gyungi Do and whole nation in the pupils from 6 to 11 years old, and that of Japan from 6 to 7 of age, while it falls behind them as age increases. (2) The growth in the circumference of the breast. The boys from 6 to 9 years old show nearly the same tendency in all districts, after that age the boys in A district tend to grow rapidly, those in B district most fall behind, and those in C, D districts show the same tendency. Contrasted with height the growth in the circumference of the breast does not show the difference in each district so far as 14 of age, but after 15 years old it shows a little difference by falling behind of pupils in A district, while those B, C, D districts show almost the same tendency. The average of the circumference of the breast in Jeonlla Bug Do of the pupils from 10 to 11 of age is almost same to that of Gyungi Do, whole nation and Japan, but shows difference after that age. (3) The growth of body weight. The body weight of boys over-all the investigated whole age shows the superiority in A district and a little lowness in D district which is almost same to that of B, C districts. In that of girls, A district is superior in from 6 to 9 of age, and all districts are nearly same after that age. The average in Jeonlla Bug Do is one and the same to those of Gyungi Do, whole nation and Japan as in the height, but shows the great difference as years grow. (4) The dietary life of the pupils in Jeonlla Bug Do depends chiefly upon a carbohydrate and is very low in the intake of fat and protein. Connected with a view point of districts, the intake of protein is a little more in A district than in the other districts, and is nearly same in the other districts. They tend more to eat mixed food, but about 40% of them do not yet eat it. The contents and taking of lunch is bad in the highest degree, to which their parents are entirely indifferent. As far as the hours of exercise are concerned with, about 40% of all pupils must go to the school from very far, which gives them the heavy physical suffering, and especially it is remarked that the middle school boys and girls should attend school from farther than the primary school boys and girls.
Investigation to Introduction of Apples on Chinese
Lee, Sung-Woo ; Kim, Kwang-Soo ; Lee, Kang-Ja ;
Journal of the Korean Society of Food Science and Nutrition, volume 5, issue 1, 1976, Pages 53~59
Around 2nd century B. C. two varieties of apple, i. e. 'Nay' and 'Imgum' were already grown in China. It can be suspected that 'Nay' came from the West because of its popular word 'Pyn Por' and 'Imgum' was originated from North East Asia because of its word 'Lii Kiem'. After this time 'Imgum' was called as its popular name 'Sha Guoo' in about 15 th century. In 17th century a new variety of 'Nay' was named as 'Pyng Guoo' and this name was replaced with 'Nay' when the variety was widely supplied. In 19th century a better variety of 'Nay' was developed in the West and it was introduced into China in 20th century which was called 'Western Pyng Guoo'. As a result there were two kinds of 'Pyng Guoo', i. e. 'Chinese Pyng Guoo' and 'Western Pyng Guoo'. However, the 'Western Pyng Guoo' was more supplied and it was said 'Pyng Guoo' which was written as 'Pyng Guoo(?果)' or 'Pyng Guoo (平果)'. At present time apples were classified into 'Sha Guoo' and 'Pyng Guoo'. The old 'Nay' is now called 'Bin Tzyy' which is hardly found. From this study it is suspected that the history of Chinese apples were affected much on our introduction history and its naming.
Studies on the Components of Vegetables

Journal of the Korean Society of Food Science and Nutrition, volume 5, issue 1, 1976, Pages 61~64
A survey of the free amino acids and organic acids in the shoot of Phyllostachys edulis was made by means of amino acid autoanalyzer and gas chromatograph. The results of the survey are summerized as follows. 1. Eighteen amino acids found in bamboo shoot were lysine, histidine, arginine, tryptophan, aspartic acid, glutamic acid, threonine, serine, proline, glycine, alanine, valine, leucine, isoleucine, methionine, tyrosine and phenylalanine, and an unknown was found. Serine showed the highest amount and more than about 44% of total free amino acids. 2. Oxalic acid was the major organic acid, and formic acid, acetic acid, maleic acid, succinic acid, fumaric acid, citric acid, tartaric acid and sorbic acid were determined, and two unknown were found.

Journal of the Korean Society of Food Science and Nutrition, volume 5, issue 1, 1976, Pages 65~68
Water extract of Xanthoxyli fructus(XW) caused contraction of the rabbit intestinal strip which was not affected by hexamethonium, promethazine and methysergide but was blocked by atropine-pretreatment. The above results suggest that cholinergic mechanism plays an important role in contractile response of XW on the rabbit intestine.
Studies on the Constituents of Korean Native Perillas
Seong, Hwan-Sang ;
Journal of the Korean Society of Food Science and Nutrition, volume 5, issue 1, 1976, Pages 69~74
Six kinds native perilla selected with superior species were cultivated by the same condition. General compositions, inorganic substances and free amino acid of a species of seeds and leaves were analyzed. The results obtained are summarized as follows ; 1. Fat components of seeds obtained from Incheon and Kunsan were 52 and 50.87% respecand these of other species were over 45%. 2. Protein components of seeds obtained from Daegu and Daejeon were 22.31 and 19.15% respectively, and these of leaves were 3 to 5%. 3. Vitamin C and
contained in leaves were above 60mg and
. 4. Leaves of perilla contained 2 to 10 times of inorganic substance comparing with seeds. Potassium was much in leaves and seeds and calcium showed plently in leaves. 5. Free amino acid in seeds of Daejeon contained 54.2mg% of arginine, 23.9mg% of alanine, and that of leaves contained 24.8mg% of glutamic acid and 9.1mg% of alanine.
Studies on the Utilization of Keratins
Suh, Hong-Kyl ;
Journal of the Korean Society of Food Science and Nutrition, volume 5, issue 1, 1976, Pages 75~80
The development of protein utilization with keratin(cattle hair and human hair) have heen investigated. The include a) conditioning of hydrolysis of keratin, b) isolation of crude protein, c) pepsin HCl digestibility of isolated protein, d) the amino acid composition of isolated protein and amino acid concentrate. The results are obtained as follow ; 1. Human hair and cattle hair were softened and hydrolysed with hot dilute alkali(especially 1% NaOH) 2. Crude protein were isolated from hydrolysed keratin by means of different solubility and isoelectric point. 3. The protein isolated was of good quality on the point of color, protein content and pepsin digestibility. 4. The amino acid concentrate obtained by acids processing was of good quality on the point of color, taste and amino acid composition.

Soybean has been considered as an important source of food protein in many countries. This experiment was attempted to determine the effect of mineral nutrition on growth and amino acid composition of soybean by using the methods developed for other plants. The results showed that S was more effective than P on the growth of soybean when the amount of cation was not changed. Among cations investigated K was more effective than Mg and Ca on its growth. However, higher amounts of Ca resulted in toxic effect. In general, the content of amino acid hydrolyzed by HCl decreased in NS and NP as well as KCa and KMg groups. Amino acids, i.e., proline, cystine, aspartic acid, lysine and histidine were not detected in NS and NP in addition to KCa and KMg groups eventhough control group showed considerable amount of these amino acids.

Lee, Geum-Yeong ;
Journal of the Korean Society of Food Science and Nutrition, volume 5, issue 1, 1976, Pages 87~92
Comparing the amount of Hb, the nutriture of the deaf-mutes are better than that of the amentias and the nursery school children. The former, however, shows less condition than that of the boys and girls in the junior physical education school (Hb : 12.7) and the normal family children (Hb : 10.8). In the group of six to eleven years old that is a class a elementary school, the physical condition such as stature, chest circumference, and weight of the deaf -mute is respectively almost the same degree, which is above standard in our country. On the contrary the degree of the amentias and the nursery school children has an inferiority approaching to the standard. In the group of twelve to fifteen years old that is a class of junior high school, the nursery school children have the lowest physical condition and the boys and girls of the physical training school the highest. The order of the growth of physical condition is as follows : Nursery school children
