(1) Haemoglobin levels were estimated by cyanmethaemoglobin method in Unoghovo (56 cases) and Tallqvist method in Ibusa 138 cases. (2) The results presented in Table 1, and 2 indicated that the average haemoglobin levels of these two surveys were low. (3) Percentage incidence of liver and spleen enlargements were 20% in Ibusa and 9% in Unoghovo (Table 6). (4) The household survey of average consumption and requirement of these two village, indicated that daily intake of iron per caput was adequate. (5) The results of these two surveys were compared with ether reported studies (Table 4 and 5).

For the purpose of finding out the differences between urban and rural primary school children aged from 7 to 12 in their physipue, 1146 (578 boys and 567 girls) urban children and 1378 (693 boys and 635 girls) rural children were obserbed by the author during 2 months period from September, 1968 to October, 1968. Following were the findings obtained from this study. 1. Physique In general, urban children showed superiority than rural children if their physique, There could be seen significant differences in their height, weight and chest-girth specially in the age group of 11 and 12. 2. Physique indices In the physique indices based on the height, the value of urban children showed superiority than rural children in relative weight but in relative chest-girth it was the other way around and there were no significant differences between these two groups in relative sitting height. The Kaup index showed higher value in urban children and the Vervaeck index in the rural children and there were no significant differences between these two groups in the Rohrer's index. 3. Comparing these figures with the Korean Standard Value, urban children showed superiority and rural children showed inferiority. Our children were inferior than the Japanese children in their physiques.

(1) Control values of the hepatic lipids of mouse analysed by means of thin-layer chromatography were as follows: Total cholesterol $5.23{\pm}0.46\;mg/g$ Free cholesterol $4.29{\pm}1.23\;mg/g$ Esterified cholesterol $0.94{\pm}0.30\;mg/g$ Triglycerides $15.56{\pm}1.84\;mg/g$ Free fatty acids $1.26{\pm}0.56\;mg/g$ Phospholipids $29.84{\pm}6.11\;mg/g$ Total lipids $62.44{\pm}12.13\;mg/g$ (2) The garlic administration brought significant elevations in the hepatic contents of free and esterified cholesterds, triglycerides, free fatty acids, and phospholipids in the mouse, when it was injected in excess (2%, 10% suspension) intraperitoneally. (3) The total hepatic lipids of mouse were increased in corelation with the amount of the garlic administered to the animals. (4) A brief discussion was made on the results obtained.

The nutrients such as protein, calcium, iron and all three of them, either by natural or chemical substances were added to the recipes of yeast breads. Acceptability test was carried for the each formulated bread before selecting eight experimental diets. Sixty albino rats were separated into ten dietary groups including eight enriched breads and two control diets of plain breads from the market, which were used as the carbohydrate sources of the each basal diet. Experimental regime was seven weeks. The growth rate, hematology, total serum protein and organ weights we compared. Generally animals on the enriched bread showed the better growth rate than the rats fed control diet. Diet H enriched protein, iron and calcium by natural foods, brought up the highest weight gain among all of the rats. Hemoglobin concentrations of the rats on the diet H and G (enriched with three nutrients by chemicals) were 14.3 and 14.2 gram % comparing with other two control groups (12.9 and 13.1 gram%). Rats on diet K (fed nothing but diet H enriched bread) showed the significantly higher growth rate, total serum protein and hemoglobin level than these on the diet L (fed only plain bread from the market).

임신 전(前) Restricted diet을 먹은 것과 Unrestricted diet을 먹은 group간에 2세의 체중증가에 미치는 영향에는 차이가 없었으며 임신 전(前) 체중변화에 있어서 Restricted diet에 숫컷이 더 예민하였다. 암컷에서는 Recovery diet을 주는 기간에는 Unrestricted group을 거의 쫓아 갔으나 숫컷에서는 그차이가 심하였다. 새끼들의 체중에 있어서 임신동안의 초기와 후기의 식이제한 group은 관계없이 임신전(全)기간 식이제한 group과 Unrestricted group간에 체중의 차이를 나타내었다. 어미의 Nitrogen 배설량에서 보면 섭취량에 대한 배설량의 백분율은 사료섭취량의 증감(增減)에 관계없이 일정하며 배설량은 사료섭취량이 많으면 많이 나가고 적으면 그것에 비례해서 적게 배설되었다. 새끼의 Nitrogen 배설량은 8 group사이에 큰 차이를 보여주지 않고 있다. Birth weight는 임신전(前) Restricted diet이나 Unrestricted diet 영향을 받지 않았으며 임신동안의 Unrestricted group의 새끼가 임신동안 전(全)기간 식이제한을 하였거나 부분적으로 식이제한을 한 group의 새끼보다 Birth weight가 컸다. litter size는 사료섭취량에 영향을 받지 않았다.

Sea-divers(woman) are living in coastal villages and their principal daily work is to dive into sea water in order to get sea-weeds, pearls etc. They are able to be stayed inside the water for a relatively long period and at the same time have a hard physical work during the period. Besides these works, they work also on farms and in homes in their rest time. Hwa-Jeon-Min('fire-field' farmers) are living in higher mountainous areas (plateau areas) and they burn off the ground for cultivation and obtain the crops on which they are living. Usually, they are far apart from cities and markets. The above mentioned two groups are special social groups in this country, consequently are interested in their food and nutritional habbits. The summarized surveyed results are as follows (See the Tables 1, 2, and 3). 1. In case of Sea-divers(woman): a. Staple foods are cereals, vegetables, and fishes and shell-fishes. These foods occupy 40%, 15%, and 24% respectively of all the foods intaken. b. Relatively large amount of protein and fat are intaken. Especially animal protein shows 64% of total protein intaken. c. Intake of vitamin $B_2$ is low but all other nutrients are intaken in relatively good amount. 2. In case of Hwa-Jeon-Min ('fire-field' farmers): a. Staple foods are cereals, potatoes, and vegetables. These foods occupy 61%, 19%, and 14% respectively of all the foods intaken. b. Intaken amount of animal foods is only 7 grams and this figure is only 0.1% of total foods intaken. c. Intake of animal protein is 0.4 to 0.6 grams per day and that of fats is 8 to 10 grams only. d. Intake of carbohydrate is very high. The calorie derived from the carbohydrate is 86% of total calorie intaken. e. Intakes of calcium, vitamin A, Vitamin $B_1$, Vitamin $B_2$, and niacin are low. Especially, calcium, vitamin A, and vitamin $B_2$ are deficient from their food habbits.
