유산소성 운동과 김치보충제 섭취가 비만 여중생의 신체 조성 및 혈중지질에 미치는 영향을 알아보기 위하여 운동군은 HRmax 60~85%운동강도의 조깅, 줄넘기운동을 매회 60분, 주 4회 실시하고, 김치 보충제 섭취군은 500 mg 의 김치 분말이 들어 있는 김치 보충제 6알 총 3g (김치약 30g)을 총 6주간 섬취하게 하였다. 실험에 참가한 여중생은 총 38명으로 운동군(EG) 8명, 김치 보충제 군(KG)12명, 그리고 운동과 김치 보충제 섭취를 병행한 군(EKG) 8명의 비만여중생 28명, 그리고 정상체중을 지닌 대조군(CG) 10명이었다. 운동 또는 김치 보충제를 6주간 섭취한 EKG, EG 그리고 KG는 CG 그룹에 비해 신체 조성 및 혈중 지질 농도가 유의하게 감소하였다. 체중, BMI 체지방 및 체지방율의 감소 정도는 EKG, EG 그리고 KG 순이었으며, 비만도를 낮추는 효과는 EKG, KG 그리고 EG순으로 나타났다. 총 콜레스테롤 및 LDL-콜레스테롤 감소는 EKG, KG 그리고 EG 순으로 나타났으며, 중성지질 감소는 EKG, EG, 그리고 KG 순이었고, HDL-콜레스테롤 농는 EKG와 EG 그룸이 KG와 CG에서 유의하게 증가하였다. 이상의 결과를 살펴보았을 때 혈중 중서이방 농도를 포함하여 체지방 조성과 관련 있는 요인들은 운동이 김치 보충제 섭취보다 효과가 있는 것으로 나타났고 혈중 콜레스테롤 농도를 감소시키는 효과는 운동보다는 김치 보충제 섭취가 효과적이었다. 그러나, 비만 여중생의 비만을 조절하는데 있어서 이 두 방법을 단독으로 실시한 결과보다는 두용법을 병행한 즉, 김치 보충제를 섭취하면서 운동을 병행한 군의 효고가 가장 현저하게 나타났다. 이상의 결과로부터 여중생의 비만을 치료하는데 있어 운동 이외에 김치를 많이 섭취하는 식이요법을 병행하명 상당한 효과가 있을 것으로 관찰되었다.

Aged garlic extract (AGE) is known to have a protective effect against immune system, endothelial function, oxidative stress and inflammation. We examined the effects of exercise with and without aged garlic extract administration on body weight, lipid profiles, inflammatory cytokines, and oxidative stress marker in high-fat diet (HFD)-induced obese rats. Forty-five Sprague-Dawley rats were fed either a HFD (HFD, n = 40) or a normal diet (ND, n = 5) for 6 weeks and thereafter randomized into ND (n = 5), HFD (n = 10), HFD with AGE (n = 10), HFD with Exercise (n = 10), or HFD with Exercise+AGE (n = 10) for 4 weeks. AGE groups were administered at a dose of 2.86 g/kg body weight, orally. Exercise consisted of running 15-60 min 5 days/week with gradually increasing intensity. AGE (P<0.01), Exercise, and Exercise+AGE (P<0.001) attenuated body weight gain and food efficiency ratio compared to HFD. Visceral fat and liver weight gain were attenuated (P<0.05) with all three interventions with a greater effect on visceral fat in the Exercise+AGE than AGE (P<0.001). In reducing visceral fat (P<0.001), epididymal fat (P<0.01) and liver weight (P<0.001), Exercise+AGE was effective, but exercise showed a stronger suppressive effect than AGE. Exercise+AGE showed further additive effects on reducing visceral fat and liver weight (P<0.001). AGE significantly attenuated the increase in total cholesterol and low-density lipoprotein-cholesterol compared with HFD (P<0.05). Exercise+AGE attenuated the increase in triglycerides compared with HFD (P<0.05). Exercise group significantly decrease in C-reactive protein (P<0.001). These results suggest that AGE supplementation and exercise alone have anti-obesity, cholesterol lowering, and anti-inflammatory effects, but the combined intervention is more effective in reducing weight gain and triglycerides levels than either intervention alone.

The silkworm is a food material that can simultaneously ingest phytochemicals from mulberry leaves, proteins with essential amino acids, and fatty acids. They are known to have hypoglycemic properties; however, further functional investigation is needed. In this study, four varieties of 3^rd day of fifth instar silkworm with different cocoon colors, namely Baegokjam (BG), Goldensilk (GS), Yeonnokjam (YN), and Juhwangjam (JH), were compared in terms of antioxidant properties and cholesterol-lowering effect. JH, which had the highest polyphenol content (+38% vs. GS, p<0.05) showed high antioxidant efficacy. Treatment with JH also resulted in the lowest cholesterol biosynthesis enzyme activity (28% vs. control, p<0.05). In the animal study, high-fat diet (HFD)-fed mice that were orally administered JH extract for 12 weeks showed lower body weight gain (-10.4% vs. HFD, p<0.05) and serum total cholesterol levels (-12.7% vs. HFD, p<0.05). Comparing the varieties, JH had the highest effect. In future studies, analysis of the active ingredients according to their variety should be done.

This study examined the effects of corn gluten (CG), wheat gluten (WG), and soybean protein isolate (SPI), as well as their hydrolysates, on weight reduction in rats fed a high-fat diet. Eight-month-old male Sprague-Dawley rats (n=70) were fed a high-fat diet (40% of the calories were fat) for 4 weeks. Rats were then randomly divided into seven groups and were fed isocaloric diets with different protein sources for 8 weeks. The protein sources were casein (control group), intact CG (CG group), CG hydrolysate (CGH group), intact WG (WG group), WG hydrolysate (WGH group), intact SPI (SPI group), and SPI hydrolysate (SPIH group). Body weight gain, adipose tissue weights, lipid profiles in plasma and liver; and hepatic activities of carnitine palmitoyl transferase, fatty acid synthase (FAS), malic enzyme, and glucose-6-phosphate dehydrogenase were assessed. The CGH group showed significant weight reduction compared with the other groups. Epididymal fat pad and plasma triglycerides in the CGH group were the lowest and were significantly different than those in the control group. FAS activity in the CGH group was significantly lower than that in the other groups. In conclusion, the CGH diet of these experimental animals demonstrated a weight-reducing effect by lowering the adipose tissue weight and by affecting the activities of hepatic lipogenic enzymes.

This study examined the time course effects of conjugated linoleic acid (CLA) on the body weight, adipose depots and lipid profiles of ICR male mice using two different sources of fats in the diet Ninety eight mice weighing 25 to 30 g were divided into four groups: beef tallow (BT) and fish oil (FO), beef tallow with CLA supplementation (BTC), and fish oil with CLA supplementation (FOC) group. Eight to nine mice in each group were fed with the experimental diets for 1, 2 or 4 weeks, respectively. All mice were fed experimental diets containing $12\%$ of total dietary fat (w/w) with or without $0.5\%$ CLA (w/w). CLA supplementation did not affect the body weight The weight of epididymal and visceral fats were significantly lower in BTC compared to those in BT groups during the periods examined (p<0.05), whereas they were significantly lower in FOC than those in FO only at 4 weeks (p<0.05). The levels of triglycerides in the plasma were significantly decreased in the BTC group than in BT group throughout the experimental periods (p<0.05). But, FOC was only effective at 4 weeks as compared to FO. The levels of total cholesterol and HDL-C were significantly increased in the BTC than in BT during the entire period (p<0.05), whereas there were no difference between FO and FOC on the levelsof total cholesterol and HDL-C. The levels of free fatty acids (FFA) were significantly decreased in BTC than in BT at 1 and 4weeks and in FOC only at 4 weeks as compared to FO (p<0.05). Taken these results together, CLA was more effective in the beef tallow diet in lowering the epididymal and visceral fat weights and triglyceride level rather than fish oil diet with CLA. Furthermore, the effect became clearer at 4 weeks than at one week of the experiment.

The effects of docking on growth traits, fattening performance, carcass characteristics and blood biochemical parameters were investigated using 24 fat-tailed Sanjabi single-born male lambs raised from a large commercial sheep herd. The lambs were randomly divided into two groups. One group (n = 12) were docked at two days of age with rubber-rings using an elastrator. The second group (n = 12) were left intact. After weaning (90 days), all lambs were moved to rustic rangelands for 40 days. Then all the lambs were fed concentrates ad libitum for 60 days during the fattening period. Growth traits, body weight and average daily gain (kg) were recorded at the end of the weaning and fattening periods. Blood biochemical parameters including urea, total protein, glucose, triglycerides, cholesterol, low-density lipoproteins (LDL) and high-density lipoproteins (HDL) were measured during the fattening period. Finally, at the end of the fattening period, eight lambs (4 intact and 4 docked lambs) were slaughtered in order to determine carcass characteristics. Fat-tail docking had no effect (p>0.05) on lamb growth from birth to weaning. Body weight and average daily gain of docked lambs were significantly higher (p<0.05) than for intact lambs at the end of the fattening period. There was no difference in carcass measurements between the two groups, except for chest depth and leg weight which were higher (p<0.05) in docked lambs. During the fattening period, cholesterol and LDL of docked lambs were less than in intact lambs (p<0.05). The current results indicated that docking with rubber rings causes an improvement in growth traits during the fattening period and leads to desirable carcass characteristics compared to intact lambs; interestingly, this procedure had a significant effect on the lowering of blood cholesterol and LDL of docked lambs.

The effects of dried leaf powders and ethanol extract of persimmon, green tea and pine needle on lipid metabolism, lipid peroxidation and antioxidative activity were investigated in rats. Forty-nine male Spargue-Dawley rats weighing 107.8$\pm$1.8g were blocked into seven groups according to body weight. Rats were raised for four weeks with diets containing either 5%(w/w) dried leaf powders of one of three different Korea traditional teas, persimmon(Diospyros kaki Thunb), green tea(Camellia Sinensis O.Ktzc)or pine needle(pinus Koreansis Sieb. Et Zucc), or ethanol from equal amounts of each dried tea powder. Food intake, weight gain, food efficiency ratio, and weights of liver, kidney and epididymal fat were significantly higher in the green-tea-powder group, and significantly lower in the pine-needle-powder and pine-needle-extract groups. Persimmon-leaf powder was found to decrease plasma total lipid, triglyceride and cholesterol concentration by increasing fecal total lipid triglyceride and cholesterol excretions. Liver cholesterol concentration was significantly lower in the green-tea and pine-needle-extract groups. Red-blood-cell superoxide dismutase(SOD) and glutathione peroxidase(GSH-px) activities were significantly increased in rats fed green-tea extract. Liver SOD activity was increased in rats fed pine-needle powder or extract, and liver GSH-px activity was increased in rats fed greentea powder. Plasma and liver thiobarbituric acid reactive substance(TBARS) concentration were both decreased in rats fed dried leaf posers or extracts of persimmon or green tea. It is believed that high vitamin E levels in persimmon leaf, and high flavonoid, beta-carotene and vitamin C levels in green tea effectively inhibited lipid peroxidation. In conclusion, persimmon and green tea leaves were effective in lowering lipid levels and inhibiting lipid peroxidation in animal tissue, while pine needles were effective and lowering body weight gain. From these results, persimmon and green tea leaves can be recommended in the treatment and prevention of chronic discorders such as cardiovascular disease, cancer and aging. As ethanol extracts from these teas were also effecitive in lowering tissue lipid levels and inhibiting lipid peroxidation, we recommend the use of discarded tea grounds for this.

We have investigated the effect of MeOH extract of the adventious root culture of Panax ginseng on hyperlipidemic rats induced by fat-rich diet. We also analyzed and compared the content ginsenoisdes of the cultured ginsengs by HPLC. After oral administration of the MeOH extract to hyperlipidemic rats for four weeks, the variables including body weight, cholesterol, HDL, LDL, and triglyceride levels in serum were measured. One of the cultured ginseng roots (CBN3) decreased cholesterol and LDL-cholesterol and increased HDL-cholesterol levels in serum. HPLC analysis demonstrated that CBN3 contains more $Rb_1$ and Rd ginsenosides than any other cultured ginsengs and cultivated ginseng. These results suggest that CBN3 with high contents of $Rb_1$ and Rd may be useful in lowering blood cholesterol.
