Objectives: In order to determine the effect of CPs, experimental studies were performed in hyperlipidemia humans. The contents of serum total cholesterol, TG (triglyceride), LDL cholesterol, HDL cholesterol, AST/ALT and BUN/creatinine were measured. Methods: We made a comparative study of total cholesterol, TG (triglyceride), LDL cholesterol, HDL cholesterol, AST/ALT and BUN/creatinine during one month off and on for twenty patients with hyperlipidemia who visited Gunpo Oriental Medical Center of Wonkwang University from December 2002 to July 2003. Results: The following result were obtained: 1. The serum TG and total cholesterol of patients who took CPs for one month showed significant (p<0.01) decrease. 2. The serum HDL-cholesterol and LDL-cholesterol of patients who took CPs for one month showed significantly increase in HDL, and decrease in LDL (p<0.05). 3. The serum AST/ALT and BUN/creatinine of patients who took CPs for one month showed no significant effects. Conclusions: According to the results mentioned above, the effects of CPs on serum triglyceride and total cholesterol of hyperlipidemia patients were significantly confirmed for decreasing effects.

This study was undertaken to determine the effect of yellow and black soybeans on plasma and hepatic lipid composition and fecal lipid excretion in Sprague Dawley rats. Animals were fed with diets containing 52% yellow soybean, 50% black soybean, or 20% casein for 7 weeks. Feeding efficiency was significantly increased in the animals fed soybeans(p<0.05). Plasma cholesterol concentration was significantly lowered in the group fed yellow soybean compared with black soybean and casein-fed control (p<0.05). Hepatic triglyceride concentration was significantly lowered in soybean groups compared with casein-fed control(p<0.05), whereas hepatic cholesterol concentration was not affected by diet treatments. Soybean feeding significantly increased fecal weight, triglyceride and bile acid contents compared with casein feeding(p<0.05). It is concluded that soybean feeding in rats affects plasma and hepatic lipid levels by increasing the excretion of triglyceride and bile acids.

Intravenous lipid emulsion is used extensively as a major component of parenteral nutrition for patients in the surgical intensive care unit. Abnormal cardiovascular function related to lipid infusion has been reported although conflicting results exist. In the present study, we investigated the effects of intravenous emulsions of long-chain triglyceride (LCT) and medium-chain triglyceride (MCT) on myocardial ischemia/ reperfusion injury and on platelet aggregation in rat. There was no difference between LCT and MCT considering the effects on left ventricular developed pressure (LVDP) and coronary flow rate (CFR) before and after ischemia/reperfusion in isolated rat heart. On the other hand, a difference was found between LCT and MCT with regard to their effects on heart rate (HR) and end diastolic pressure (EDP) after ischemia/reperfusion. After ischemia/reperfusion, HR was significantly (P<0.05) reduced and EDP significantly (P<0.05) inc.eased by LCT (18$\pm$2.0% and 42.8$\pm$8.9%, respectively), but not by MCT Ex vivo platelet aggregation induced by collagen was reduced by LCT infusion, but not by MCT These findings suggest that MCT may have slightly more favorable effect than LCT on the myocardial function after ischemia/reperfusion in rat.

Effects of the dietary supplementation of Codonopsis lanceolata root on triglyceride and cholesterol levels in the serum, liver, breast muscle and bile in male Cobb$\times$Cobb chicks were investigated. The chicks (15-42 days old) were fed diets supplemented with 0, 0.25 and 0.5% Codonopsis lanceolata root. No differences were observed in body weight, feed conversion ratio, gall bladder weight or abdominal fat deposition among the control group and the two treatment groups. Liver weights were higher in chicks fed a 0.5% Codonopsis lanceolata diet than in those fed the control diet (p<0.05). However, serum levels of both glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) were not different among the three groups. Broiler chicks fed either 0.25% or 0.5% dietary Codonopsis lanceolata root showed decreased serum levels of triglyceride, total cholesterol and low density lipoprotein cholesterol compared to the control group (p<0.05). Supplementation with either 0.25% or 0.5% dietary Codonopsis lanceolata root decreased the triglyceride and total cholesterol levels in liver and breast muscle compared to the control group (p<0.05). Biliary cholesterol increased by 15% in chicks fed 0.5% dietary Codonopsis lanceolata root, suggesting that the biliary excretion of cholesterol had been elevated by dietary Codonopsis lanceolata root (p<0.05). In conclusion, these results indicate that dietary Codonopsis lanceolata root can decrease triglyceride and cholesterol levels in the serum, liver and breast muscle of broilers.

Hypoglycemic effect of Tabebuia avellandae was investigated in the streptozotocin(STZ)-induced diabetic rats. Diabetes was induced in male Sprague-Dawley rats by injections of STZ (45 mg/kg, i.v.). Rats weighing 200-250 g were divided into 6 groups: normal, STZ-control, hexane fr., CHCl$_3$fr., BuOH fr. and $H_2O$ fr. group. Normal and STZ-control rats received 3% Tween 80 only. Four groups of diabetic rats were administered orally at doses of 100, 400, 300 and 400 mg/kg/day of hexane, CHC1$_3$, BuOH and $H_2O$ fr. respectively. Fractions were administered orally to the rats for 7 days after STZ injection. All rats were anesthetized with ether, blood samples were taken by cardiac puncture for clinical chemistry and the rats were killed by exsanguination. Liver, kidney, heart and spleen were removed, weighed and analyzed. We measured glucose, protein, cholesterol and triglyceride levels in the plasma and glycogen, cholesterol and triglyceride levels in liver. The extent of blood glucose decrement in rats administered $H_2O$ fraction was greater than that in the STZ-control rats. The serum cholesterol and triglyceride levels were significantly lowered by administration of $H_2O$ fraction compared with those of STZ-control group. Treatment of rats with Tabebuia avellandae fractions caused decreases in STZ-induced elevation of cholesterol and triglyceride. Liver triglyceride level was significantly lowered hexane and BuOH fraction group compared with STZ-control group. These results suggest that $H_2O$ fraction of Tabebuia avellandae has the hypoglycemic action against STZ-induced diabetic rats.

This study was an attempt to compare the energy, nutrient intake, blood lipids, and body fat distribution of diabetics with those of normal control subjects. Daily energy and nutrient intake were measured by convenient method. The following anthropometric measurements were made on all participants : weight, height, and waist and hip circumference. We matched 31 pairs with diabetics and nondiabetic control subjects by sex, age, body weight and height, and made comparisons between two groups to observe the effect of diabetes in lipid profiles. Aslo the effect of exercise in diabetes was investigated. The results obtained were as follows : 1.The average of daily energy intake of diabetics was 1, 927 kcal and that of nondiabetics was 2, 159 kcal. Percentage of energy in diabetics is that carbohydrate : protein : fat = 69:13:18 2. When diabetics were divided into obese and nonobese group according to RBW, 33% of diabetics were obese and energy intake was not significantly different between the two groups, but VLDL - cholesterol concentration was significantly higher in the obese group. 3. Energy intake, BMI, RBW and total cholesterol level of upper obesity group were significantly higher than those of lower body obesity group in male diabetic subjects. 4. When matching 31 pairs of diabetics and nondiabetics according to sex, age, body weight and height triglyceride concentration and WHR of diabetics were measured to be significantly higher than those of nondiabetics. 5. Although energy intake was not significantly different between exercise and nonexercise groups, triglyceride, blood glucose, RBW, BMI were significantly lower in the exercise and nonexercise groups, triglyceride, blood glucose, RBW, BMI were significantly lower in the exercise group than the nonexercis group in diabetics. 6. BMI and RBW were not correlated with cholesterol or triglyceride, but WHR correlated significantly with both cholesterol and triglyceride. In conclusion, diabetics had higher triglyceride concentration and WHR than nondiabetics. WHR may be better than BMI or RBW for predicting alteration in lipid profile and exercise seems beneficial for controlling blood glucose and lipids in diabetics.

가정용 마아가린의 물성에 적합한 원료유지를 제조하기 위하여 옥수수기름(corn germ oil, CGO)과 극도경화 대두유(fully hydrogenated soybean oil, FHSO)의 혼합유를 무작위 에스테르 교환하였을 때 이들 혼합유의 이화학적 성질의 변화를 연구하였다. 에스테르 교환은 triglyceride 조성을 분석한 결과 $80^{\circ}C$에서 sodium methoxide를 0.4% 사용하였을 때 35분만에 반응이 완결되었다. 융점과 고체지 함량은 에스테르 교환에 의해 현저하게 감소하였고, 거칠고 큰 결정형태는 미세하고 균일한 크기로 변화하였다. 에스테르 교환 전후의 지방산 조성은 변화가 없었으나, triglyceride 조성은 상당한 변화를 나타내었다. PN별로 triglyceride 조성을 분석한 결과 PN 42, 44, 52 및 54는 감소하였는데 이는 $GU_3$와 $GS_3$의 감소와 관련이 있으며, PN 46, 48 및 50은 증가 하였는데 이는 $GU_2S$와 $GUS_2$의 증가와 관련있는 것으로 판단되었다. 본 연구에서 융점, 고체지 함량, 결정형태 등의 변화와 지방산 조성으로 볼 때 CGO와 FHSO를 80 : 20과 75 : 25로 혼합하여 에스테르 교환한 것이 가장 바람직한 물성과 영양성을 갖는 가정용 마아가린의 원료 유지임을 알 수 있었다.

미역(Undaria pinnatifada)은 낮은 칼로리 및 요오드의 원료로써 천연체중조절식품으로 알려져 있다. 미역이 체중조절식품으로 알려져 있음에도 불구하고, 지방세포 분화 및 지방축적에 관한 저해 기작은 연구가 미비하다. 본 연구에서는 3T3-L1에서 지방세포로 분화가 일어나는 단계에서 미역에탄올추출물의 효과 및 기작을 확인하였다. 미역에탄올추출물의 독성과 지방축적저해효과는 MTT assay, Oil red O staining, RT-PCR과 western blot으로 분석하였다. 미역에탄올추출물은 50 ${\mu}g/ml$의 농도에서 독성을 띄지 않았다. 3T3-L1의 분화 및 지방세포에서 triglyceride축적과정동안 50 ${\mu}g/ml$의 미역에탄올추출물을 처리하였으며, 미역에탄올추출물은 지방세포에서 triglyceride의 축적을 40% 감소시켰다. 지방세포 특이적 단백질인 Peroxisome proliferator activated receptor ${\gamma}$ ($PPAR{\gamma}$), leptin과 Hormone sensitive lipase (HSL)의 발현은 RT-PCR과 western blot으로 확인하였다. $PPAR{\gamma}$의 과발현은 지방세포의 분화를 촉진시킨다. 또한 지방세포 크기의 증가와 세포 내 triglyceride의 함량에 따라 leptin은 세포 외로 분비된다. 그러므로 $PPAR{\gamma}$와 leptin은 비만의 지표로 사용된다. 첨가한 미역에탄올추출물의 농도가 높아질수록 $PPAR{\gamma}$와 leptin의 발현이 억제되었다. 이상의 결과를 통하여, 미역의 에탄올 추출물은 지방전구세포의 분화를 억제시키며, 지방세포 내 triglyceride의 축적을 저해하는 것으로 판단된다.
