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.

This study was performed to investigate the changes of the serological parameters of the rats fed a high fat and high cholesterol diets with or without quercetin supplement for five weeks. Thirty Sprague-Dawley male rats ($152.1{\pm}17.0\;g$ of body weight) were randomly divided into three groups with 10 rats in each group. Rats in the control(C) group were fed the high fat and high cholesterol diet containing 15% lard, 2% cholesterol and 0.5% sodium cholate (w/w). Rats in two treatment groups were fed the same diet supplemented with 0.25% quercetin (Q-0.25) or 0.5% quercetin (Q-0.5) on the weight to weight basis, respectively. The final body weight, gain of body weight, the amount of feed intake and the feed efficiency of rats in between control and treatment groups were not significantly different. Serum glucose, total protein, albumin, globulin and albumin/globulin (A/G) ratio of rats showed no significant differences between control and treatment groups. Serum total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C) and atherogenic index(AI) of rats in both Q-0.25 and Q-0.5 groups were significantly lower than in C group (p < 0.05). However serum high density lipoprotein-cholesterol (HDL-C) was significantly higher in both Q-0.25 and Q-0.5 groups than in C group (p < 0.05). The levels of triglyceride in sera of rats showed no significant differences between control and treatment groups. The values of AST and ALT in sera of rats showed no significant differences between control and treatment groups. Therefore the supplementation of quercetin to high fat and high cholesterol diet in rats was effective in reducing the levels of serum lipids to cause cardiovascular diseases and in elevating the level of HDL-C to protect cardiovascular diseases.

An aqueous extract of oriental herbal composition named Onchengyeum and curcumin, an antioxidant isolated from turmeric (Curcuma Zonga L.) reduced hepatotoxicity induced by carbon tetrachloride ($CCI_4$). Improved liver function was observed by measuring the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), blood urea nitrogen (BUN), creatinine (CRE), total cholesterol (T-CHO), triglyceride (TG), low density lipoprotein cholesterol (LDL-CHO), high density lipoprotein cholesterol (HDL-CHO), total protein (TP), albumin (ALB) and total bilirubin (BIL) in serum. Hepatic parameters monitored were levels of cholesterol (CHO), triglyceride (TG), and malondialdehyde (MDA) and activities of cytochrome P450 (CYP), NADPH-CYP reductase, superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), glutathione S-transferase (GST), glutathione reductase (GR), and glutathione peroxidase (GPx). The histopathological examination showed that the treatment of Onchengyeum and curcumin relieved the ballooning degeneration of hepatocytes which had been generated by $CCI_4$. The results suggested that hepatoprotective effects of Onchengyeum and curcumin possibly are due to their promising antioxidative activity.

All lipoproteins are made up of three major classes of lipids : triglycerides, cholesterol, and phospholipids. Lipoproteins vary in their relative content of these lipids as well as in size and protein content. Human low density lipoprotein (LDL) is a main carrier for cholesterol in the blood stream, and it is well established that cholesterol deposits in the arteries stem primarily from LDL and that increased levels of plasma LDL correlated with in increased risk of atherosclerosis. Various lines of research provide strong evidence that lDL may become oxidized in vivo and that oxidized-LDL is the species involved in the formation of early atherosclerotic lesions. the most crucial findings in this context are the following : (1) Oxidized -LDL has chemotactic properties and if present in the intimal space of the arteries would recruit blood monocytes which then can develop into tissue macrophages ; (2) marcrophages take up oxidized-LDL unregulated to from lipid laden foam cells ; (3) Oxdized-LDLis highly cytotoxic and could be responsible for damage of the endothelial layer and for the destruction of smooth muscle cells.

The study was conducted to investigate the effects of dietary calcium and soy isoflavone on body fat and lipid metabolism in high fat-induced obesity. Four week old female C57/BL6J mice, known as a good model of diet-induced obesity, were fed low Ca and high fat diet for 6 weeks. After induced obesity, mice were divided into six groups according to diets varying calcium contents (0.1 or 1.5%) and genistein contents (0 or 500 or 1,000 ppm). Body weight, fat pad (perirenal fat and parameterial fat), adipocyte size, serum total lipid and total cholesterol were significantly decreased by both high Ca intake and genistein supplementation. However, the effect of genistein supplementation showed in low Ca-fed groups. Serum LDL-cholesterol and TG were significantly decreased by high Ca intake and genistein supplementation, respectively. In liver, lipogenic enzymes (fatty acid synthase and malic enzyme) activity and TG were significantly decreased by both high Ca intake and genistein supplementation. This inhibitory effect of genistein on lipogenic enzymes showed in low Ca-fed groups. But liver total cholesterol and total lipid were significantly decreased by high Ca intake and genistein supplementation, respectively. Fecal excretion of total lipid, total cholesterol and TG were significantly increased by high Ca intake, not by genistein supplementation. In conclusion, high calcium intake and genistein supplement may be beneficial for suppression of obesity through direct anti-adipogenesis by decreasing fat weight and size and indirect anti-lipo-genesis by inhibiting lipogenic enzymes activity and improving lipid profile.

Electrical acupuncture has been shown to induce hypoglycemic effect in streptozotocin diabetic rats. The Zusanli acupoints have been widely used in traditional Chinese medicine to relieve symptoms of diabetes mellitus. But, the effects of electrical acupuncture stimulation of different frequencies are still unclear. We designed an experiment to investigate the effect of electrical acupuncture of high (100 Hz) and low (2 Hz) frequencies on Zusanli acupoint for 15 minutes in streptozotocin diabetic rats. They were divided into 4 groups, high frequency electrical acupuncture (HFEA group, n=5), low frequency electrical acupuncture (LFEA group, n=5), without any treatment (control group, n=5) and normal group (n=5). After 2 weeks of treatment, the HFEA and LFEA groups had a significantly decreased glucose concentration in serum in comparison to the control group. Additionally, the HFEA group had a significantly decreased glucose concentration in serum compared with the LFEA group. Both the HFEA and LFEA groups had a significantly decreased Immunoglobulin G concentration in serum compared with control group. The LFEA and control groups had a significantly increased cholesterol concentration in serum compared with the normal group, but the HFEA did not have a significantly increased cholesterol concentration. Thus we suggest that electrical acupuncture stimulation at the Zusanli acupoints is effective on hypoglycemic effect and immune function. Overall, the therapeutic effects of electrical acupuncture at 100 Hz was better than effects at 2 Hz.

Bacillus subtilis and Enterococcus faecium are commonly used probiotics. This study aimed to identify the effect of live combined Bacillus subtilis R0179 and Enterococcus faecium R0026 (LCBE) on obesity-associated hyperlipidemia and gut microbiota in C57BL/6 mice. Forty male C57BL/6 mice were divided into four groups: normal group (N group), model group (M group), low-dose group (L group), and high-dose group (H group). Mice were gavaged with LCBE at 0.023 g/mice/day (L group) or 0.23 g/mice/day (H group) and fed with a high-fat diet for 8 weeks. In vitro E. faecium R0026 showed an ability to lower the low-concentration of cholesterol by 46%, and the ability to lower the high-concentration of cholesterol by 58%. LCBE significantly reduced the body weight gain, Lee index, brown fat index and body mass index of mice on a high-fat diet. Moreover, LCBE markedly improved serum lipids (including serum triglyceride, total cholesterol, low-density lipoprotein and high-density lipoprotein) while also significantly reducing liver total cholesterol. Serum lipopolysaccharide and total bile acid in L and H groups decreased significantly compared with M group. PCR-DGGE analysis showed that the composition of gut microbiota in the treatment groups was improved. Akkermansia muciniphila was found in H group. The PCA result indicated a similar gut microbiota structure between LCBE treatment groups and normal group while the number of bands and Shannon diversity index increased significantly in the LCBE treatment groups. Finally, qPCR showed Bifidobacterium spp. increased significantly in H group compared with M group, LCBE alleviated liver steatosis and improved brown adipose tissue index.

The present study investigated the anti-obesity effect of pine cone (PC, Pinus koraiensis) supercritical extract in high-fat diet (HFD)-induced obese mice. Male C57BL/6J mice were treated with HFD, HFD+catechin, and HFD+PC [two different doses, 20 mg/kg body weight (b.w.) and 100 mg/kg b.w.] in each AIN93G supplement for 8 weeks. Treatment of HFD mice with both low and high doses of PC significantly reduced body weight gain compared to HFD mice. Liver weight of mice was reduced in both the low and high dose PC-supplemented groups (24.19% and 19.83%, respectively). Total adipose tissue weight of mice was reduced in both the low and high dose PC-supplemented groups (45.54% and 62.66%, respectively). Serum total cholesterol, triglyceride, LDL cholesterol, and HDL cholesterol were reduced in the low and high dose PC-supplemented groups, and ratios of HDL cholesterol to LDL cholesterol increased by 94.55% in the high dose PC-supplemented group. Serum leptin was significantly reduced in the low and high dose PC-supplemented groups (28.14% and 62.72%, respectively). These results were supported by genetic expression of protein and enzymes related to lipid metabolism assessed by real-time PCR. There was significant reduction of lipid regulatory transcription factors such as $PPAR-{\gamma}$, C/EBP, and SREBP and lipid enzymes such as fatty acid synthesis and lipoprotein lipase in the low and high dose PC-supplemented groups. However, there was no statistical difference between low and high dose PC treatments. These results suggest that pine cone supercritical extract supplementation is able to regulate serum lipid profiles by reducing total cholesterol, triglyceride, and LDL cholesterol levels, followed by regulation of expression of lipid metabolic factors, resulting in reduction of weight gain in HFD-induced obese mice.

Objective: This experiment was conducted to evaluate the effects of a corn- or cassava- based diet on the production of meat-type ducks. Methods: Four hundred day-old ducks were used in this experiment. They were divided into five groups with each group replicated eight times. The ducks fed the corn-based diets served as the control group. The four other groups comprised different treatments, with each one given the cassava-based diet based on phase-feeding. Three treatments were fed the cassava-based diet from 16, 28, and 35 d; respectively up to 42 d of age and the other group was fed the cassava-based diet from 1 to 42 d of age. Results: The results indicated that ducks on either the corn- or cassava-based diets were similar in growth during 1 to 9 d of age. However, toward 35 to 42 d, the cassava-diet produced a higher weight gain (p<0.05). The cassava-based diet was better than the corn-based diet at increasing the outer and inner breast weights at 28, 35, or 42 d (p<0.05). In contrast, the corn-based diet was better at increasing abdominal fat (p<0.05). The two diets did not differ in their effects on the serum triglyceride, cholesterol, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, very-low-density lipoprotein-cholesterol, and liver cholesterol. The corn-based diet, however, caused a highly significantly greater level of liver triglyceride (p<0.01). Conclusion: The results of this study suggest that both the cassava- and corn- based diets are similar in their effect on meat-type ducks during the starter stage but toward the finisher stage, the cassava-based diet has a better influence on weight gain and carcass characteristics.
