Seven day's menus consisting of the Korean traditional dietary patterns were prepared according to the Korean nutrition allowances per capital of whole population. After cooking foods one day's meal was collected, homogenized for one week. Nutrients in each day's meal were analysed. The results of this analysis are as follows ; Lipids contents were about 23% higher than the data obtained nationwide nutrition survey conducted in 1984. This suggests the increasing tendency of the fat the oil consumption . PUFA ratio in lipid was 35%, that the customary Korean cooking include high confirmiry amount of vegetable oils. Daily tocopherol intake was 8.3mg . This results is believed to as one reference to set up Korean R.D.A for tocopherol.

흰쥐의 lipoprotein을 제거한 혈장내의 지질전이 활성도와 지진전이를 저해하는 활성도를 측정하였다. 지질전이 활성도의 측정은 방사성 동위원소가 함유된 cholesteryl ester (CE)와 triglyceride (TG) 로 표지된 인체의 혈장 low density lipoprotein 으로부터 high high density lipoprotein(HDL) 으로 전이되는 방사성 동위원소의 양을 측정하여 계산하였다. 지질전이 저해 활성도는 정제한 인체 혈장 지질전이 단백질에 의한 지질전이를 저해하는 정도로서 측정하였다. 흰쥐의 혈장에는 지질전이 활성도가 거의 없으나, 지질전이를 저해하는 활성도는 존재하였다. 지질전이 저해정도는 측정용액내의 lipoprotein 양이 증가할수록 감소하였다. 일반적으로 흰쥐의 HDL은 인체의 HDL에 비하여 CE 의 함량은 높으며 TG의 함량은 낮다. 흰쥐의 혈장에 인체의 혈장으로부터 정제한 지질전이 단백질을 가하여 37$^{\circ}C$에 24시간 두었을 때, HDL 로부터 very low density lipoprotein (VLDL)으로 CE가 이동하여 VLDL 의 CE 함량이 4배나 증가하였다. 반면에 VLDL로부터 HDL$_2$로TG가 이동하여 $HDL_2$의 함량은 TG함량은 9배나 증가하였다. 이와같은 현상은 흰쥐의 혈장 Lipoportein이 지질전이의 기질로서의 결함은 없음을 보여준다. 따라서 지질대사에 관한 실험에서의 흰쥐에 의한 실험결과의 해석에는 인체 혈장에 비하여 혈장에는 lipoprotein사이의 중성지질의 전이나 교환이 거의 없다는 특성이 고려되어야한다.

To observe the effect of the different level of PUFA and marginal tocopherol supplement on HDL-chol, tissue tocopherol content and fatty acid composition, the rats were supplied either safflower oil or conconut oil with or without tocopherol supplement to the experimental diet. Plasma tocopherol level was not greatly influenced by the different dietary fat and similar effect was observed in the liver but not in the adipose tissue. HDL-chol level was reduced in the high PUFA diet regardless of tocopherol content. No effect by tocopherol supplement was observed in the fatty acid composition of liver and adipose tissue lipid in both dietary PUFA levels . There was also no increase in the content of tissue polyenoid acid by tocopherol in the high PUFA diet . Fatty acid composition of tissue lipid was rather more influenced by dietary fat. Lauric and myristic acid contents were higher in the low PUFA diet and linoleic acd and total polynoic acid content were higher in the high PUFA diet. With tocopherol supplement tocopherol /PUFA ratio of tissue was increased but the ratio of high PUFA diet was significantly lower than that of low PUFA diet. Marginal tocopherol supplement could not reduce the peroxidizability index of high PUFA diet.

The food habits and health complaints were studied for 459 persons, 60 years and over, in the rural area, JKurye-Gun Chonnam, from April 28 to May 1, 1986. by the questionnaire sheets ; one was for the food habits, and the other was for health complaints(the standarized questionnair designed in Todai Health Index). The results obtained were as follows. 1) Mean score of the food habit was 11.2$\pm$3.5 in male and 10.8$\pm$2.9 in female. The score in both sexes showed a falling tendency as their ages increased. 2) THI scores in surfferings eye & skin, mouth & anus were higher (p<0.01, p<0.05, p<0.01) in female than in male. As age increased, the THI score showed a rising tendency. In case of male, THI socre in digestive organs was higher (p<0.05) in sixties than in other age. 3) The rate of living together with their family or spouse in the male aged was 77% higher than in the female aged. whilte the rate of celibacy in the female aged was 28%, higher than 3% in the male aged. DMF value was higher in female than male. The amount of alcohol ingestion were 2.1 and 0.6 Cup in male and female, respectively and the amount of smoking were 10.5 and 3.1 cigarettes in male and female respectively. Both alcohol intake and smoking were higher in male(p<0.01) 4) In case of male, the correlation coefficient between the score of food habit and THI score was negative in suffering eye & skin, mouth & anus, respectively, and in female it was negative in digestive, mouth & anus. As the score of food habit become low, the THI score become high. 5) Those living alone in both sexes showed a low score in food habit.

This study was performed to see the effects of lead poisoning and dietary protein levels(6, 15 and 40 % casein diets) on growth, protein and lipid metabolisms in growing rats. It was also investigated whether the high protein intake would alleviate lead toxicity by decreasing Pb absorption and/or increasing Pb excretion. The results obtained were summarized as follows ; 1) Weight gain, F.E.R liver weight, weight and length of bone in Pb-administered groups were lower than in Pb-free groups. However, these values in the 40% casein diet group with Pb were increased to the level in 15% casein diet group without Pb. 2) Hematocrt and hemoglobin content in blood were lower in Pb -adminstered groups than in Pb free groups. Especially, these levels were lower in 6% casein diet group with Pb than in any other group. 3) Plasma protein level in th e 40% casein casein diet group was the highest of all groups and those of Pb-administered groups tended to be lower than those of Pb-free groups. Plasma lipid and cholesterol levels were increased with decreasing dietary protein level, and these levels were higher in the animals exposed to Pb than in free groups.4) Total liver protein, lipid and cholesterol contents were increased with increasing dietary protein level, and these contents were lower in Pb-administered groups than in Pb free groups. 5) Fecal Pb excretion was not different between 6 and 40% casein diet groups. However, urinary Pb excretion was higher in the 40% casein diet group than in the 6% casein diet group. Above results suggest that, in exposing to the Pb pollution, sufficient protien intake must be recommended. High protein intake seemed to alleviate lead toxicity by increasing urinary Pb excretion.

Several aspects including physical development, reflex acquistion, neuromotor development and learning behavior at Y water maze were compared at the progeny of rats fed low 91.2mg/kg diet) or adequate leves(22mg/kg diet 0 of pyridoxine during growth, gestation, lactation, and adult period. Physical development and development of reflexes (righting reflex, cliff avoidance, negative geotaxis, palmar grasp, and startle reflex to sound) appeared different between control and deficient groups but not significantly. At the 2nd week, rats spent more time in supported standing during 6 minute period was longer in the control then the deficient groups. In the Y-water maze position reversal test, learning ability as judged by the number of errors was not different among three groups, but the rats in supplemented group(DC) reached the escape platform in significantly shorter time than the other two groups, which may suggest their emotional instability. In the visual discrimination test, the performance of rats from the supplemented group had the lower errors than the other groups on the early test days. but as the testing period progressed, the performance of rats in the supplemented group became inferior to those of the control and deficient groups. The performance of control group became superior to that of the deficient group.
