This study was designed to investigate the influence of Eosungcho (Houttuynia cordata Thunb) mixture on the plasma lipids of pigs. Experimental groups were divided into 3 groups: control group(0%), 5% and 10% Eosungcho feeding groups. Plasma concentration of total cholesterol, atherosclerotic index, free cholesterol and cholesteryl ester were significantly lower in the Eosungcho powder 5% and 10% feeding groups than control group. Plasma contents of HDL-cholesterol, cholesteryl ester ratio, triglyceride and phospholipid were significantly different between 10% Eosungcho feeding group and control group. Plasma concentration of LDL-cholesterol was significantly love in 10% Eosungcho feeding group($76.5{\pm}5.4mg/dL$) than in control group($86.5{\pm}5.6mg/dL$). Plasma concentration of VLDL and chylomicron were showed similar tendency to LDL-cholesterol. Also, blood sugar, GOT and GPT concentration were significantly lower in 10% Eosungcho feeding group than in control group. In control group, the ratio of saturated fatty acid to unsaturated fatty acid was 58.1 : 51.9, but in 5% and 10% Eosungcho feeding groups, those were 42.1 : 57.9 and 41.0 : 59.0, respectively. The component of main fatty acid was different between control group and Eosungcho feeding groups. In Eosungcho feeding groups, main unsaturated fatty acids were oleic acid(18:1) and linoleic acid(18:2). From the results, addition of Eosungcho powder might be effective in improving the plasma lipid components in pigs.

We investigated the quality characteristics of eggs produced from laying hens fed with non-supplemented diets (A) and diets supplemented with 3% (B) and 5% (C) of sea urchin shell powder for efficient applications of sea urchin shell. There was no significant difference in the proximate composition. Ca and Fe contents of (B) and (C) groups were higher than those of (A) group. Contents of phosphorus and magnesium, however, showed no significant differences among the groups. (B) and (C) groups had higher in essential amino acid contents than (A) group except tryptophan. Taurine was detected in all groups. Analysis of fatty acid showed that (B) and (C) groups contained more unsaturated fatty acids. The DHA contents of (A), (B) and (C) groups were 0.56%, 0.68% and 0.89%, respectively. These results show that sea urchin shell possesses the potential as supplement of laying hens diets to produce functional eggs.

Nutritional compositions of three Tochukaso species (Paecilomyces tenuipes hosted by Larva and pupa, Cordyceps militaris, C. sinensis) were compared. Fruiting body and host fractions were separately analyzed. Fruiting body fraction of P. tenuipes (36.6%) hosted by larva was higher than that hosted by pupa (10.2%), an indication that the quality of the former is superior to the latter. Carbohydrate content of C. sinensis (39.6%) was $2.5{\sim}7$ times higher than those of others, probably due to the presence of polysaccharides. Protein and crude lipid contents of C. sinensis and C. militaris were 25.8 and 10.3%, and 75.1 and 3.9%, respectively. C. sinensis showed the lowest Ca content and $30{\sim}75$ times higher Fe content among the samples tested. Vitamin A content of C. militaris was 308.9 IU/100g, two fold higher than those of the other species. Saturated fatty acid content was the highest in P. tenuipes (pupa, 27.7%), whereas unsaturated fatty acid was the highest in P. tenuipes (larva, 83.3%). Aspartic acid, glutamic acid, and glycine were abundant in all species. Cordycepin content of C. militaris was $20{\sim}50$ times higher than those of the other species.

발효유 원료유중에 항생물질이 함유되어있을 경우 이것이 발효유 제조에 미치는 영향을 검토하였다. 발효유의 원가유 살균과정, 배양기간, 보존기간중에 있어서 항생물질의 변화를 검토하기 위하여 Bacillus stearothermophilus var. calidolactis C 953을 사용한 cylinder plate법으로 penicillin의 역가를 측정하였다. 저온 장시간 $살균(60^{\circ}C,$ 30분) 조건에서는 조금도 불활성화되지 않았으나, 온도를 높이고, 시간을 길게함에 따라 점점 불활화률이 높아져 $고압멸균조건(121^{\circ}C,$ 15분)에서는 약 90% 이상이 불활화되었다. 또 현재 우리나라에서 발효유제조에 사용되고 있는 Lactobacillus casei, Hy3와 Lactoba-cillus bulgaricus Hy4A, Hy4B를 사용하여 $37^{\circ}C에서$ 배양할 경우 배양기간 중에 있어서 penicillin은 2일내에 95% 이상 불활화되었다. 그리고 $보존기간(5^{\circ}C)$ 중에는 phosphate buffer(pH 6.0)와 10% skim milk의 경우에 10일까지도 거의 불활화가 되지 않았으나, 발효유내에서는 5일만에 85% 이상이 불활화된다는 결과를 얻었다. 이와같은 발효유 배양기간과 보존기간 중의 penicillin 불활화의 원인을 규명하기 위하여 각종 유기산의 영향을 조사한 결과(조건 pH.3.30~3.45, 보존온도 $37^{\circ}C),$ 염산과 유산의 경우 24시간, 구연산의 경우 48시간, 초산의 경우 72시간내에 실험에 사용한 penicillin 농도의 99.99%가 불활화되었다. 이러한 결과로 볼 때 유산발효에서 penicillin이 불활화되는 주원인은 발효에 의하여 생성된 유기산에 의한 것으로 추정된다.방식이군이 중지방식이군과 고지방식이군에 비해 혈장내 LCAT 활성이 유의하게9p<0.001) 증가하였다. 3) 간의 콜레스테롤합성 능력은 정어리유군이 다른지방군보다(p<0.001), 무지방식이군이 식이지방첨가군보다(p<0.001), 동물성지방군의 식물성유지군보다 유의하게(p<0.001) 증가하였으나, 식이 지방의 수준에 의한 차이는 나타나지 않았다. 수용성 식이섬유소가 생리져 기능이 거의 비슷하고 무독성이 관찰됨으로써 신갈나무로부터 제조된 수용성 식이섬유소의 제조 방법이 우수하다고 볼 수 있다.있었다.세에 해당되는 중년 여성의 에너지, 단백질, 철분 섭취량을 권장량과 비교하여 보면, 각각 74.8$\pm$12.6%, 94.6$\pm$26.4% 및 64.5$\pm$14.1%로 당뇨군 (각각 112.8$\pm$28.5%, 157.8$\pm$68.2%, 92.8$\pm$21.7%)에 비해 유의하게 낮았고 정상군과는 유의한 차이를 보이지 않았다.상고나성이 있었다. 혈중 호모시스테인 농도는 질병의 위험요인으로서 뿐 아니라 대사적으로 밀접하게 연관된 비타민 영양상태의 biomarker로서도 그 영향력이 크다고 할 수 있다. 따라서 성별에 다른 다양한 연령집단에서 건강한 일반인과 심혈관계 질환자 등을 대상으로 호모시스테인과 비타민 영양상태에 대한 연구가 체계적으로 이루어 져야 할 것이다.태를 보다 효율적으로 증진시킬 수 있는 대안이 마련되어져야 한다고 사료된다.$\ulcorner$순응$\lrcorner$의 범위를 벗어나지 않는다. 그렇기 때문에도 $\ulcorner$순응$\lrcorner$과 $\ulcorner$표현$\lrcorner$의 성격과 형태를 외형상으로 더욱이 공간상에서는

Purpose: The aim of this study was to estimate total sugar intake and sugar intake-related dietary habit and nutrient intake of elementary school students. Methods: Subjects included 701 elementary school students (351 boys and 350 girls) residing in Jeju. The research analyzed a sample and was carried out using the 24 hour recall method and one day consumption of total sugar. Results: The average daily total sugar intake was 55.3 g (male 53.1 g, female 57.6 g). Total sugar intake per meal was 6.3 g (11.4%) from breakfast, 6.9 g (12.5%) from lunch, and 7.2 g (13.0%) from dinner, 34.9 g (63.1%). Major food groups of total sugar were milks (17.04 g), grains and their products (12.79 g), fruits and their products (9.40 g), and sugars and sweets (7.30 g). In analysis of the amount of total sugar consumption from several recipes, much was taken in from dessert and snacks such as dairy products (15.08 g), bread and snacks (6.4 g), beverages (5.5 g), fruits (5.1 g), and ice cakes (4.8 g). Total sugar consumption was high for rices and side dishes such as noodles (5.1 g), stir-fried foods (2.3 g), fried foods (1.4 g), cooked rice with seasoning (1.4 g), and hard-boiled foods (1.1 g). In comparison of total sugar consumption for sugar sources, daily intake of natural sugar, added sugar, and natural and added sugar were 25.8 g, 23.3 g, and 6.2 g, respectively. High sugar intake group, which was over 20% of the energy from total sugar intakes, consumed significantly less Fe, Zn, and niacin than the low sugar intake group, which was below 20%. Conclusion: Total sugar intake of fifth graders of elementary schools on Jeju Island was 55.4 g/day, and it was usually intake from snacks. Therefore, elementary school students need nutritional education for proper selection of better snacks and for reduction of dietary sugar intake.
