본 연구는 레시틴이 강화된 홍삼 추출물을 제조하는 방법을 개발하기 위하여 수행되었다. 우선 대두유 레시틴을 대두유와 일정 비율로 혼합하여 LCS를 제조하였다. 고형분 함량이 10%인 홍삼 물추출물과 LCS의 비율을 3:1로 하여 혼합하여 vortexing한 뒤 혼합액을 원심분리하여 오일 층과 수용액 층을 분리하였다. 수용액 층에 대하여는 레시틴과 사포닌의 정성 및 정량분석을 행하였다. 홍삼 추출물에 대하여는 LCS처리 전 후 지방산 조성과 조지방 함량도 조사하였다. 또한, LCS를 처리한 홍삼 추출물에 대하여는 농축 후 $4^{\circ}C,\;25^{\circ}C,\;40^{\circ}C$/6개월 Falcon 튜브에 넣어 보관하면서 상부 1/3과 하부 1/3의 레시틴 함량을 조사함으로써 안정성을 조사하였다. LCS처리로 인한 홍삼 추출물의 조지방 함량은 변화 없었고, 지방산 조성 변화는 oleic acid의 증가 이외에는 특별한 결과를 관찰할 수 없었다. 홍삼 추출물로의 레시틴 이행율은 대두유에 대한 레시틴의 첨가 비율이 증가함에 따라 정비례적으로 증가하였다. LCS-처리 전 후 홍삼 추출물 중의 지방산 조성과 진세노사이드 함량은 유의한 차이가 없는 것으로 나타났다. TLC 및 HPLC 조사 결과 역시 LCS-처리 전 후 차이가 없는 것으로 나타났다. 상기 3가지 조건에 6개월간 보관하면서 보관용 튜브의 상 하부 1/3의 레시틴 함량과 사포닌 조성 변화를 조사한 결과 차이가 없는 것으로 보아 LCS-처리 홍삼 농축액의 안정성은 만족할 만한 것으로 사료된다. 이상의 결과로부터 레시틴 함유 대두유 혼합액으로 홍삼 추출물을 처리하는 방법은 홍삼 추출물에 레시틴을 강화시킬 수 있는 안정성이 뛰어나고 처리 공정이 간편한 방법이라 판단한다.

In recent years, organic ginseng cultivation has increased because customers prefer organic ginseng products due to the morphological quality as well as the safety such as the residuals of chemically-synthesized pesticides. Therefore, some of paddy and upland fields were converted into organic ginseng fields. Soil chemical properties, soil microflora, and soil-inhabiting animals were investigated in paddy-converted and upland organic ginseng fields in Sangju city, Korea. There was few difference in the soil chemical properties, and the soil nutrient concentrations, such as nitrate-N, Av. $P_2O_5$ between the two field types, and exchangeable cations such as K and Ca were within the ranges which are recommended by the standard ginseng-farming manual. Changes in microflora were also assessed by analyzing phospholipid fatty acid composition. Overall, indicators of microbial groups were greater in the upland field than in the paddy-converted soil, but they were not significantly different. In addition, there was no significant change in the abundance of nematodes, collembolans, and mites between the two field types probably because of the high variation within the field types. In this study, it was suggested that soil chemical and biological properties for organic ginseng cultivation were greatly influenced by the variation of topography and soil management practices rather than field types. Further study may be needed to investigate the influence of these factors on soil chemical and biological properties in organic ginseng soils.

In order to study the safety of ginseng ingested as a food substance, rats were fed ginseng added feed (subgroup 1: 0.625g/kg feed; subgroup 2: 1.25g/kg feed; subgroup 3: 2.5g/kg feed) for periods up to 6 months. Growth rates, blood composition, blood cell counts, and histopathological studies were carried out on both the control and test animals to study the effect of ingested ginseng. Following results were obtained: 1. The growth rates of the test and control animals were similar with the exception of the subgroup 3 in the 2-month fed animals who had a lower weight gain, and the subgroup 2 in the 4-month fed group who had a higher weight gain than the controls. 2. Liver, spleen, kidney, brain, lung and heart weights were similar between the test and the controls. 3. RBC, WBC, hematocrit, and hemoglobin values were similar between the test and control animals. the blood composition determination showed a similar level of alkaline phosphatase, triglyceride, total cholesterol, S-GOT, free cholesterol between the test and controls. However, free fatty acid, total lipid and S-GPT levels decreased while phospholipid, total protein, and HDL-cholesterol levels tended to increase. 4. Fl, F2 generations showed no abnormai values in blood count, organ weight and external appearance. 5. No histopathological differences were observed between the test and control animals even after a long-term administration of ginseng. However, there was evidence that ginseng promotes hematopoiesis in test animals. 6. These results suggest that ginseng is not only safe as a food substance but may indeed strengthen the body and help-prevent diseases of old age.

Results & Conclusions : 1. Sample A and Sample B significantly decreased body weight, serum LDL-cholesterol level, serum free fatty acid level, serum total lipid level, serum phospholipid level and serum leptin level in comparison with control group. 2. Sample B significantly decreased serum total cholesterol level and serum triglyceride level in comparison with control group. 3. Sample B significantly increased serum HDL-cholesterol level in comparison with control group. According to above results, the author suggested that ETG was able to be used for the herbal medication of obesity. 4. ETG significantly increased rCBF, and increased CMF in a dose-dependent. 5. ETG significantly decreased MABP in a dose-dependent. 6. rCBF was significantly and stably increased by ETG(10 mg/kg, i.p.) during the period of cerebral reperfusion, which contrasted with the findings of rapid and marked increase in control group. This results were suggested that ETG significantly increased rCBF by dilating arterial diameter and activating serum leptin level. So that, the present author thought that ETG had an effects of obesity and complication coming from obesity(ischemic cerebral and cardiac disease).

Objectives: This study was designed to evaluate the efficacy of Pharbitidis Semen (PS) on obesity using 3T3-L1 cells and high-fat-diet rats. Methods: After the administration of PS at a concentration of 0.125, 0.25, and 0.50 mg/ml in 3T3-L1 cells, the degree of differentiation of adipocytes was measured by Oil Red O staining. The experimental animals were divided into five groups in vivo. Normal group: diet-fed normal group (Normal), Control group (Control): high-fat-diet (HFD)-fed, Positive control group (PC): HFD+Contrave 200 mg/kg, PS_Low group: HFD+PS 250 mg/kg group, PS_High group: HFD+PS 500 mg/kg. Results: The total cholesterol, low density lipoprotein-cholesterol (LDL-cholesterol), and triglycerides (TG) content of the PS medication groups were significantly lower than those of the control group. In addition, high density lipoprotein cholesterol (HDL-cholesterol) tended to increase, and free fatty acid, total lipid, and phospholipid tended to decrease, but the decrease was not statistically significant. The administration of PS inhibited the differentiation of 3T3-L1 adipocytes, and a statistically significant difference was found in the group administered with 0.125 mg/ml. The mRNA expression of $PPAR-{\gamma}$ and leptin, which are involved in the differentiation of adipocytes, was observed using reverse transcription polymerase chain reaction (RT-PCR). The expressions of $PPAR-{\gamma}$ and leptin significantly decreased in comparison with the control and the positive control.

This experiment was conducted to determine the effects of a low-protein diet supplemented with DL-methionine plus L-cystine (Met + Cys) on the growth performance and fat accumulation of female broiler chicks during the growing period (3-6 wks old). A low-protein diet (17% CP; 3,200 ME kcal/kg) was supplemented with Met + Cys (1.1 : 1.0) at levels 0.75, 0.94, 1.25, 1.31 or 1.50% of diet, respectively. Another diet with 21% CP and 3,200 ME kcal/kg served as the control group. All essential amino acids were adjusted to meet the National Research Council (1984) requirement for chicks. Feed and water were given ad libitum. Body weight of the chicks fed the low-CP diets supplemented with Met + Cys were heavier than those of the control birds. Feed conversion ratio and feed intakes were not significantly different between and among the treatment groups. Similary, abdominal fat content was not significantly different among the various treatments except that of the chicks fed the low CP diet with 1.25% Met + Cys which was higher than that of the control group. Fatty acid synthetase (FAS), acetyl-CoA carboxylase (ACC) activities and carcass protein content were not influenced by dietary treatments. Carcass fat content was lowest in chicks fed low CP diet with 0.75% Met + Cys and highest in the group that received 1.50% Met + Cys supplementation. Liver triglyceride increased as Met + Cys supplementation level increased. Various lipid fraction concentrations (cholesterol ester, free cholesterol, and phospholipid) in the serum went up as Met + Cys increased up to 1.25% after which it levelled off. Results of this experiment suggest that it is possible to reduce dietary protein level from 21% to 17% for growing broiler chicks by the supplementation of Met + Cys when other EAA were sufficient.
