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.

Folk Remedies symbolize the medical art of the common people, and contain their special emotion and colloquial expressions. They are medical treatments in which the medical history and the tradition and the soul of a people are incorporated. They are handed down in various ways. This study introduces some of folk remedies. For example, powder of tigers' bones heals neuralgia. Rice wine brewing up with ginger is effective in a cold. Water boiling with safflower does good in neuralgia. Pasting herba houttuyniae takes effect in skin disease. To Decoct and drink old hardy orange is effective in urticaria. Water boiling with fructus corni alleviates a fever. Camellia oil or rhizoma cnidii or iris is used for the extermination of vermin and the antiseptic. In the end, the practical application of these remedies to the resources of industry and education will be discussed.

The effects of various n-6/n-3 ratios(about 2, 4, 6, 8) of dietary fatty acids on various lipid levels and prostaglandin production were studied at the constant P/S ratio (1.5-1.6) in young (5 weeks old) and adult(8 months old) Sprague-Dawley rats using palm oil, safflower oil and sardine oil. The concentration of serum cholesterol tended to increase with the increasing n-6/n-3 ratio. The tendency of HDL-cholesterol levels was similar to serum cholesterol levels. These were not apparent differences between young and adults rats. Serum triglyceride levels increased according to increasing n-6/n-3 ratio in young rats. These were generally high in the adult rats compared with the young rats. Though liver cholesterol level tended to increase according to the increasing n-6/n-3 ratio in the young rats. The liver triglyceride level did not change according to the n-6/n-3 ratio. However, these levels were apparently higher in the adult than in the young rats. The fatty acid compositions of phosphatidylcholine(PC) were similar in serum and liver. The arachidonate/linoleate ratios in tissue PC were influenced by the n-6/n-3 ratio. They tended to be lower in the adult rats compared with the young rats. It was suggested that the activity of $\Delta$6-desturase was decreased by aging. Production of platelet thromboxane A2(TXA2)and aortic prostacyclin(PGI2) was not apparently influenced with n-6/n-3 ratio. Whereas the ratio of TXA2/PGI2 was the lowest value at 3.8 of n-6/n-3 ratio, expecially in the young rats. Thus this ratio seemed to be a desirable level to protect atherosclerosis. These results indicate that the lipid level and prostaglandin production were influenced not only by n-6/n-3 ratio(under constant P/S ratio) but by aging, particulary triglycerde level and arachidonic/linoleic acid ratio.

Carthamus tinctorius L. (known as safflower) is a valuable oil plant whose importance is increasing rapidly in the world due to its high adaptation to arid regions. The seeds of this unique plant are especially used in edible oil, soap, paint, varnish and lacquer production. Its flowers are used in vegetable dye production and medicinal purposes beside its features as a coloring and flavoring in food. After the oil is removed, the remaining pulp and plant parts are used as animal feed, and dry straw residues are used as fuel. Beside all these features, its usage as a herbal medicinal plants for various diseases has gained importance on recent years. In this study, it was designed a plant metabolomic approach which transfers all the recent data processing strategies of untargeted metabolomics in clinical applications to the present study. Q-TOF LC/MS-based analysis of the extracts (70% ethanol, hexane, and chloroform) for both seed and flowers was performed using a C18 column (Agilent Zorbax 1.8 µM, 100 × 2.1 mm). Differences were observed in seed and fruit extracts and these differences were visualized using principal component analysis (PCA) plots. The total number and intersections of the peaks in the extracts were visualized using peak count comparison graph. Based on the experimental results, the number of the detected peaks for seeds was higher than the ones for the flowers for all solvent systems to extract the samples.

기능성물질인 CLA를 양어사료에 첨가하여 기존의 어류와는 다른 기능성 역돔 생산을 시도하였다. 사육 8주간 매 2주마다 어체내의 CLA축적도를 측정한 결과 8주 후 $1\%$ CLA 첨가구에서는 41.3 mg/g of fat였으며, $10\%$ CLA 첨가구에서는 180.9mg/g of fat으로 역돔의 정상적인 성장을 고려하지 않는다면 $10\%$의 사료내 첨가도 가능한 것으로 생각된다. 그러나 정상적인 성장을 고려하면 CLA의 적정 첨가량은 $1\%$로 나타났으며, 그 이상의 첨가시에는 성장 저하 현상을 나타내었다. 합성된 CLA는 총 6 종류의 이성체로 구성되어 있었고, 그 중 c9, t11 및 t10, c12 이성체가 $85\sim90\%$를 이루고 있었으며, 첨가된 CLA 함량에 따라 축적되는 양도 달라졌다. 사육 8주 후, 육 및 간 중의 지방산 조성은 n-9, 3 계열은 거의 화를 나타내지 않았으나, n-6계열은 첨가된 CLA의 함량에 따라 육 및 간에 축적되는 양은 $5\sim27\%$로, $1\%$ CLA 첨가구가 가장 높았고, $10\%$ CLA 첨가구가 가장 낮은 함량비를 나타내었다.

The experiments were conducted to determine effects of a mixture of conjugated linoleic acid (CLA) isomers on T cell subpopulations and responsiveness to mitogen of splenocytes in male broiler chicks. In experiment 1, birds (8-d old) were fed basal, CLA-(CLA) and safflower oil-supplemented (SA) diets which were formulated by supplementary 10 g CLA or safflower oil/kg to the basal diet for 14 d. Broiler starter diet, which mainly consisted of corn and soybean meal, was served as the basal diet. Proliferative response and interleukin (IL)-2-like activity stimulated by concanavalin (Con) A at a concentration of $10{\mu}g/ml$ of splenocytes in chicks fed the CLA diet were greater than in chicks fed the SA diet, but not at $20{\mu}g$ Con A/ml. Percentage of CD3-positive T cells in splenocytes did not differ between chicks fed the SA diet and CLA. Ratio of CD4-positive T cells to CD8- positive T cells was significantly affected by dietary fat source. In experiment 2, broiler chicks (1-d old) were fed the same diets as in experiment 1 for 14 d. Results of splenocyte proliferation to Con A were similar to those in experiment 1, but phytohemaggulutinin (PHA)- or pokeweed mitogen (PWM)- induced splenocyte proliferation did not differ between the CLA and SA fed groups. Supplementation with SA or CLA to the basal diet tended to have a depressive effect on the proliferation, with the greater effect being that of SA. In experiment 3, effect of an addition of CLA to splenocyte culture medium on splenocyte proliferation was determined. An addition of CLA to the culture medium resulted in reduction of the splenocyte proliferation to Con A, but an addition of linoleic acid. When PWM and PHA were used as mitogen, the inhibitory effect of CLA and linoleic acid on the proliferation did not differ. The results suggested that the effect of dietary CLA on splenocyte proliferation was similar to that of SA, although the effect of dietary CLA on sub-populations was slightly different from that of dietary SA. Further studies are needed to clarify whether use of CLA would be beneficial for maintaining or enhancing T cell immunity in chicks.

플라이애시의 부유선별 과정에서 교반속도와 공기주입량과 같은 기계적 요소 변화에 따른 영향을 알아보고자 본 연구를 실시하였다. 본 연구에서는 미연탄소 함량이 약 3.4 ~ 3.7% 수준인 화력발전소 플라이애시를 사용하였다. 대표적인 부유선별의 선별 요소인 pH, 교반속도, 포수제 첨가량, 기포제 첨가량 변화에 따른 영향을 살펴보았을 때, Safflower oil을 포수제로 사용하여 첨가량을 800 g/ton, pH 7, 교반속도 1,200 rpm, 기포제 첨가량이 400 g/ton였을 때, 미연탄소 회수율과 미연탄소 함량이 각각 63%, 34%로 나타났다. 이 때 부상물 SEM/EDS 분석을 통해 알아본 결과, 구형의 플라이애시 미립자가 미연탄소 내에 고용되거나, 광액 내에 가라앉지 못하고 기포와 함께 부유함으로써 미연탄소의 함량을 낮추는 것으로 나타났다. 교반속도와 공기주입량과 같은 기계적 요소를 변화시킨 실험에서는 공기주입량 8L/min, 교반 속도 900 rpm에서 미연탄소 회수율 74%, 미연탄소 함량 67%인 것으로 나타났다. 이는 낮은 교반속도와 추가 공기주입으로 인하여 광액 내 와류의 강도가 낮아져, 미립의 플라이애시 입자가 미연탄소와 함께 부유되는 현상을 방지됨으로써, 미연탄소 회수율과 미연탄소 함량이 향상된 것으로 나타났다. 또한, 교반속도와 공기주입량을 각각 800 rpm, 6 L/min으로 설정하였을 때 미연탄소 회수율과 미연탄소 탄소함량이 각각 80%, 70%로 향상되어 가장 우수한 것으로 나타났다.

본 연구는 식이지방(우지, 잇꽃유)을 급여한 마우스에게 토마토가 면역활성에 미치는 영향을 평가하기 위하여 수행하였다. AIN-76 diet에 포화지방(beef tallow)과 불포화지방(safflower oil)을 각각 5%씩 중량비로 혼합한 식이를 대조군으로 하였고, 실험군은 토마토(수분함량, 95%)를 고려하여 건물기준으로 0.5%를 첨가한 실험식이를 제조하여 BALB/c 마우스에게 10주 동안 급여하였다. 지연성 과민반응검사는 4, 7, 10주에, 항체생산 세포수측 정은 7, 10주에 실시하였다. 혈액은 심장천자(heart puncture)로 채취하였으며 저장된 혈청은 양적혈구(SRBC)에 대한 적혈구응집소가측정(AGG test)에 이용하였다. 각각의 장기는 적출하여 칭량하였고, DTH test후 적출한 비장을 대상으로 세포조직학적 검사를 실시하였다. 토마토군은 대조군에 비해 4주와 10주의 비장계수(spleen index)와 흉선계수(thymus index)가 통계적으로 높았다(p<0.05). 양적혈구에 대한 지연성 과민반응검사에서 토마토군은 4주, 7주, 10주 모두 24시간의 반응값이 대조군 보다 통계적으로 유의하게 높았다(p<0.05). 토마토군은 3시간은 7주, 24시간은 4주, 48시간은 4주와 10주에서 대조군에 비해 통계적인 유의성이 있었다(p<0.05). 항체생산 세포수는 식이급여 7주에 토마토군이 대조군보다 통계적인 차이가 나타난 반면 10주는 차이가 없었다. 양적혈구에 대한 응집소가는 식이의 급여기간이 길어질수록 감소하였는데, 토마토군이 대조군에 비해서 특히 10주의 응집소가는 유의성이 있었다. 임파구(Iymphocyte)는 토마토군이 대조군보다 다소 증가하였고, 비장조직 검사결과 토마토군은 백색수(white pulp)가 심하게 증식되어 활발한 면역반응을 보였다.

Powdery and downy mildews caused by Sphaerotheca fusca and Pseudoperonospora cubensis are the most common and serious diseases of cucumber worldwide. In spite of the introduction of highly effective systemic fungicides, control of these diseases remains elusive. Hence, this study aimed to develop an alternative method to chemicals in controlling the diseases by using different types of cooking oil. Egg yolk, which contains a natural emulsifier, lecithin, was selected as a surfactant to emulsify the oils. Among the different cooking oils used, soybean, canola (rape seed), safflower, sunflower, olive, and corn oils showed over 95% control values against powdery mildew of cucumber in a greenhouse test. In particular, 0.3% canola oil emulsified with 0.08% yolk (1 yolk and 60 ml canola in 20 l spray) was found to be the most effective. The treatment resulted in 98.9% and 96.3% control efficacies on powdery and downy mildews, respectively, of cucumber in the field. Canola oil exhibited direct and systemic effect, wherein powdery mildew of cucumber was suppressed only on treated leaves but not on non-treated leaves in a plant, while mycelia and conidia of the pathogen were severely distorted or destroyed by the treatment. The prospect of using the canola oil and yolk mixture as a natural fungicide is highly promising because of its effectiveness, availability, low cost, simple preparation, and safety to humans and the environment. The use of the canola oil and yolk mixture is expected to be an effective fungicide for use in organic farming and home gardening.
