This study was performed to investigate the effect of acorn supplementation on the lipid profile and redox antioxidant enzyme activities in obese rat. Obesity in the rats was induced by feeding diet contained 10％ lard and 0.5％ cholesterol for 4 week. After 4 weeks, rats were divided into the following 5 groups; high fat diet (Control), high fat diet plus 10％ Acorn powder (APlO％), high fat diet plus 20％ Acorn powder (AP20％), high fat diet plus 0.2％ Acorn extract (AE0.2％), high fat diet plus 0.5％ Acorn extract (AE0.5％). Total food intake and food efficiency ratio (FER) was not significantly different by acorn powder and extract supplementation. But, body weight was decreased by 20％ acorn powder. Acorn powder and extract supplementation for 4 weeks tend to decrease total cholesterol and triglyceride level on the serum and hepatic tissue. There was no significant difference in hepatic glutathione (GSH) content among all the groups. The hepatic GST activity in acorn supplemented groups was lower than that of control. Glutathione peroxidase and catalase activities were higher in acorn supplemented groups than that of control. Hepatic TBARS levels of experimental groups were also significantly lower than that of control group. Our finding suggest that acorn powders and extract might have potential role for improving lipid profiles and antioxidant enzyme activities in obese rats.

This study was initiated to investigate the effects of lyophilized purslane (Portulaca oleracea) powder (5% and 10%) on lipid levels in rats fed a hypercholesterolemia-inducing diet (1% cholesterol). During the four week study, there were no significant differences in either weight change or the food efficiency ratio between the group fed the hypercholesterol diet alone (HC) and the groups fed the purslane powder (HCPO-I and HCPO-II, 5% and 10% purslane, respectively). In serum, the levels of total lipid, total cholesterol and LDL-C decreased significantly for the group fed the 10% purslane powder (HCPO-II) in comparison with the group fed the 5% purslane powder (HCPO-I). The atherogenic index (AI) was reduced by about 51% for the group fed the 10% purslane powder (1.47) in comparison with the HC group (3.03). The activities of GOT, GPT, ALP and LDH decreased significantly for the groups fed the purslane powder in comparison with the HC group. Regarding liver tissue, the levels of total lipid, total cholesterol and triglyceride decreased significantly for the purslane powder-fed rats compared to the HC group. The fecal lipid profiles increased significantly as the amount of purslane powder was increased. Compared to the HC group, the fecal total cholesterol and triglyceride levels were higher in the group fed the 10% purslane powder by about 2.8 times and 2.3 times, respectively. For the serum and liver tissue, the content of lipid peroxide decreased significantly in the groups fed purslane powder compared to the HC group. The data from this experiment show an increase in the lipid levels discharged in feces, suggesting that the supplementation of purslane powder to a hypercholesterolemia-inducing diet reduces lipid levels.

This study was aimed to investigate whether or not black soybean supplements affect levels of lipid profiles and female hormone (estradiol; E2, estrogen; Es) in 57 middle-aged women (in their 40s and 50s). All subjects were randomly assigned to the control or black soybean supplement group (BSS group). The BSS group was allocated to use dietary black soybean supplements (100 g/day) for 8 weeks. The BSS subjects were divided into two subgroups; 14 women were in the premenopausal group and 15 were in the postmenopausal group. We measured lipid profiles, female hormones and nutrient intakes at 0 weesk and 8 weeks. After 8 weeks, high-density lipoprotein (HDL) cholesterol was significantly decreased (P<0.01) and the athrogenic index (AI) was significantly increased (P<0.01) in control group. In BSS group, triglyceride (TG) (P<0.05), low-density lipoprotein (LDL) cholesterol (P<0.01) and LDL-HDL ratio (LHR) (P<0.01) were significantly decreased. However, E2 and Es were significantly increased (P<0.01). Compared to the control group, the BSS group revealed statistically significant improvements in the levels of TG, HDL-cholesterol, AI, LHR, E2 and Es (P<0.05). In the premenopausal group, HDL-cholesterol (P<0.05), E2 (P<0.01) and Es (P<0.05) were significantly increased and AI (P<0.01) and LHR (P<0.01) were significantly decreased after 8 weeks. In the postmenopausal group, E2 (P<0.05), and Es (P<0.05) were significantly decreased. However, total cholesterol (TC) was increased (P<0.01). Compared to the postmenopausal group, the premenopausal group was significantly improved on HDL-cholesterol, LDL-cholesterol and LHR (P<0.05). In conclusion, black soybean supplements may have beneficial effects on improving lipid profiles and female hormones.

This study was conducted to examine the correlation among meals variety, obesity index, blood pressure, and lipid profiles of Korean adults. A total of 308 adults(men 124, women 184) measured the anthropometric characteristics, blood pressure, dietary intake using 24-hour recall method, and serum lipid profile. The average ages of the study subjects were 50.9 yrs in men and 51.4 yrs in women. The average height, weight and BMI were 166.3 cm, 68.4 kg, $24.7\;kg/cm^2$ in men and 154.3 cm, 59.8 kg, $25.0\;kg/cm^2$ in women, respectively. The numbers of food items in meal of men and women were 14.1, 15.9 for breakfast, 15.7, 15.9 for lunch, 14.7, 14.1 for dinner, respectively. The numbers of dish items in meal of men and women were 4.0, 4.3 for breakfast, 4.3, 4.3 for lunch, 4.2, 3.9 for dinner, respectively. The average blood pressure, total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol and atherogenic index were 126.6/76.0 mmHg, 181.0 mg/dL, 157.7 mg/dL, 40.9 mg/dL, 108.6 mg/dL, 3.5 in men and 123.2/73.6 mmHg, 185.0 mg/dL, 137.3 mg/dL, 44.8 mg/dL, 112.7 mg/dL, 3.2 in women, respectively. The total cholesterol was negatively correlated to the number of food item for lunch(p<0.05). Therefore, more systematic studies to investigate the meal variety roles of blood lipids in meals of adults were required.

We examined the associations between adiponectin or leptin and serum ICAM-1 levels in seventy-six hypercholesterolemic patients (mean age 59 yrs, 25 males and 51 females, LDL-cholesterol>=130mg/dL at screening). Blood lipid profiles and HOMA-IR derived from fasting glucose and insulin concentrations were determined. Serum levels of adiponectin, leptin and ICAM-1 were analyzed using ELISA The results showed that serum levels of leptin were positively associated with serum levels of ICAM-1 independent of age, sex and BMI (r=0.392, p<0.001). Serum levels of adiponectin were negatively associated with serum levels of ICAM-1 independent of age, sex and BMI (r=-0.343, p<0.005). Stepwise multiple linear regression analysis showed that serum leptin was an independent factor to be associated with serum ICAM-1 levels after adjusting for age, sex, BMI, alcohol intake, smoking status, blood lipids such as total cholesterol, triglyceride, HDL cholesterol and LDL cholesterol and HOMA-IR (p<0.001). With respect to adiponectin, its association with serum ICAM-1 was attenuated but still significant when further adjustments were made for age, sex, BMI, alcohol intake, smoking status, blood lipids such as total cholesterol, triglyceride, HDL cholesterol and LDL cholesterol and HOMA-IR (p<0.005). In conclusion, this study suggests that adiponectin and leptin are associated with endothelial derived inflammation.

To study the relation between serum fatty acids and coronary artery disease(CAD), 194 subjects were randomly selected and divided into three groups(control, single vessel disease group(SVD), muliple vessel disease group(MVD)) according to the angiographic results. Total serum levels of fatty acids and serum phospholipid(PL)-fatty acids(FAs)were analysed using gas chromatography and their associations with CAD were examined. Different patterns of total serum fatty acid levels were found in men and women. Levels of most fatty acids of SVD and MVD were significantly lower in men, while those of MVD were significantly higher in women. In terms of PL-FAs in both men and women, the levels of PL-FAs follow the order of control < SVD < MVD and in women, the difference was significant. Various ratio(including ratios denoting the activites of desaturase and elongase) of total serum-and PL-FAs were similar in the three groups. In the relation of serum fatty acids to serum lipid profiles, PUFA & LDL showed a negative correlation, while, SFA & LDL-cholesterol and PUFA and HDL-cholesterol showed positive correlatons. correlations. Systolic blood pressure and alcohol intake levels negatively affected the levels of serum LA, AA, EPA and DHA in the risk factor analysis. These findings are consistent with other evidence indicating that fatty acid compositions are changed in CAD, especially on the concentration base and the change was related to the severity of the disease. Therefore, for the purpose of disease prevention and therapeutic use, balanced intakes of various fatty acids must be seriously considered.

본 연구는 도라지 추출물의 항 비만 효과를 관찰하기 위하여 비만 흰쥐에 도라지 추출물을 투여 한 후, 비만 흰쥐의 체중 변화와 혈청 중의 지질 프로파일을 측정하였다. 그 결과 도라지 추출물의 투여는 실험 시작 후 1주부터 8주까지 대조군에 비하여 감소하는 경향을 보였다. 고지방식이로 비만을 유도하였을 때, 정상군 보다 total cholesterol, triglyceride, fatty acid, total lipid의 함량이 증가되던 것이 도라지 추출물의 투여로 total cholesterol, triglyceride, fatty acid, total lipid의 함량이 현저히 감소하는 경향을 나타냈다. PG군의 total cholesterol$(77.2\pm3.3mg/dl)$은 대조군에 비해 약 7.0% 감소되었으며, PG군의 triglyceride$(103.6\pm9.0 mg/dl)$은 대조군에 비해 약 21.1% 감소되었다. 아울러 PG군의 fatty acid$(630.1\pm45.9 uEq/L)$함량은 대조군에 비해 약 19.6% 감소하였다. 또한 PC군의 경우 총 지질 함량은 $396\pm23.7mg/dl$ 이며, 이는 대조군에 비해 약 9.1% 감소하는 경향을 나타냈다. 이상의 결과로 미루어 보아 도라지 추출물은 비만의 개선 효과가 있을 것으로 생각되며, 앞으로 많은 연구가 병행하여야 할 것으로 사료된다.

본 연구에서는 대두가공부산물의 하나인 비지(SCR: soybean crud residue)를 이용하여 만든 메주를 항비만 또는 혈중지질 개선용의 식 의약 소재로써의 직접적인 이용 가능성을 검토할 목적으로 우리나라의 전통메주 발효의 주요 미생물의 하나인 Aspergillus oryzae var effuses KACC 44990로 발효시킨 메주(ASCR)와 홍국 제조용으로 사용되는 미생물의 하나인 Monascus pilosus IFO 4480으로 발효시킨 메주(MSCR) 및 이들을 1:1(w/w)로 상호 혼합한 메주(AMSCR)를 제조하였으며 이들 메주를 각 2%씩 함유하는 고지방식이로 8주간 마우스를 사육하였을 때의 체중, 혈액 및 간 조직 지질의 함량 변동과 간 조직 ROS 생성계 및 소거계 효소의 활성을 측정하였다. SCR, ASCR, MSCR 및 AMSCR은 고지방식이 또는 비만으로 유도된 간, 심장, 신장, 고환의 비대 현상과 부고환 주변 지방의 함량을 감소시키는 효과가 있으며, 그 효과는 AMSCR>ASCR>MSCR>SCR 순으로 ASCR과 AMSCR에서 높았다. SCR, ASCR, MSCR 및 AMSCR은 고지방식이 또는 비만으로 유도된 혈청과 간조직의 중성지방과 총콜레스테롤 함량을 감소시키는 효과가 있으며, 혈청의 HDL 콜레스테롤 함량을 높이면서 LDL 콜레스테롤 함량을 낮추는 효과가 있다. 특히 ASCR은 중성지방의 함량을, 그리고 MSCR은 콜레스테롤의 함량을 각각 감소시키는 효과가 높으며, ASCR과 MSCR을 혼합한 AMSCR에서 종합적인 지질개선 효과가 높았다. SCR, ASCR, MSCR 및 AMSCR은 고지방식이 또는 비만상태에서 나타나는 간 손상을 예방하는 효과가 있으며 그 효과는 AMSCR>ASCR>MSCR>SCR 순으로 컸다. SCR, ASCR, MSCR 및 AMSCR은 고지방식이 또는 비만상태에서 나타나는 ROS 생성계 효소인 XO의 활성을 억제시킴과 동시에 ROS 소거계 효소인 SOD, GPX 및 GST의 활성을 높이는 효과가 있으며 그 효과는 AMSCR>ASCR>MSCR>SCR 순으로 컸다. 결론적으로 본 실험을 통하여 발효비지는 항비만 효과가 있을 뿐만 아니라 지질을 개선할 수 있음을 확인하였다.
