Objectives : This study was designed to investigate the effects of an aqueous extract from Buddleja officinalis Maxim (ABO) on vascular dysfunction in low-density lipoprotein receptor deficient (LDLr KO) mice. Methods : Present study showed that LDLr KO mice were fed a high fat diet consisting of 60 kcal% fat, with or without 200 mg/day/kg ABO of diet, for 14 weeks. Results : High fat diet-LDLr KO mice were treated with ABO were completely normalized by lowering glucose. ABO reduced intima/media thickness in a high fat diet-LDLr KO mice without affecting plasma cholesterol and triglyceride levels. ABO caused endothelium-dependent relaxation in the acetylcholine-precontracted aorta of high fat diet-LDLr KO mice. ABO increased eNOS expression, while decreased cell adhesion molecules expression in high fat diet-LDLr KO mice. Conclusions : In conclusion, chronic treatment with ABO improved hyperglycemia and endothelium-dependent vascular relaxation as well as exhibited anti-inflammatory effect in diabetic atherosclerotic mouse model, independent of effects on plasma lipids.

Diagnostic approaches such as angiography, ultrasound, computed tomography and nuclear magnetic resonance have limitation for contributing to the early clinical diagnosis of atherosclerosis. Recently, $^{99m}Tc-labelled$ low density lipoprotein was developed to detect early atherosclerotic lesion by external imaging with gamma camera. To determine whether $^{99m}Tc-LDL$ scintigraphy can visualize the active atherosclerotic lesion, rabbits were injected with $^{99m}Tc-LDL$, 3 months after feeding dietary fat (lanolin) and we obtained following results. 1) Labelling efficiency of $^{99m}Tc-LDL$ was $79\sim88%$. 2) Biodistribution study of normal rabbits with $^{99m}Tc-LDL$ revealed the high activities in spleen, adrenal gland, liver, kidney which are major organs of high metabolic rate of LDL. 3) Three months after feeding lanolin, serum cholesterol was markedly increased from $74{\pm}17mg/dl$ to $979{\pm}153mg/dl$ and histologic study of aorta after sacrificing the rabbit demonstrated marked atherosclerotic changes. 4) Atherosclerotic lesion of abdominal aorta which was confirmed with histologic study could be demonstrated in $^{99m}Tc-LDL$ scintigraphy after feeding lanolin for 3 months. In conclusion, the results of this preliminary investigation suggest that it may be possible to image active atheromatous lesion with $^{99m}Tc-LDL$. It is anticipated that this promising agent may allow the in vivo monitoring of preclinical atherosclerotic lesions and may be useful to evaluate the metabolic pathway of LDL in humans.

Objectives : The purpose of this study is to compare the effects of laser acupuncture to the 532 nm on the five transport points with the heart meridian for treatment to hypertensive disease in rats with L-NAME induced hypertensive. Methods : Hypertensive was induced by L-NAME for 3 weeks. The laser acupuncture therapy on the five transport points of heart meridian(Laser Well Point-HT9, Laser Brook Point-HT8. Laser Stream Point-HT7, Laser River Point-HT4 and Laser Sea Point-HT3) was treated twice a week for 5 times. The hypertensive was measured using a cardiac hypertrophy, atherogenic index, TG/HDL-cholesterol ratio, TCHO, HDLC, TG, AST, ALT, antioxidative effectiveness and glutathione peroxidase quality of hypertensive rats induced by L-NAME. Results : Blood pressure were decreased significantly after the laser acupuncture of Well, Brook and Sea Point groups. Cardiac hypertrophy were decreased at the laser acupuncture of Brook and Stream Point groups. Athrogenic index was decreased at the laser acupuncture of Well, Stream, River and Sea Point groups. TG/HDL-cholesterol ratio was decreased at the laser acupuncture of all groups. Total cholesterol was decreased significantly at the laser acupuncture of Well Point group. High density lipoprotein cholesterol and total cholesterol were decreased significantly at the laser acupuncture of Well, Stream and River Point groups. Triglyceride was decreased significantly at the laser acupuncture of Stream Point group. Cu/Zn-Superoxide Dismutase (Cu/Zn-SOD) and glutathione peroxidase(GPX) were increased significantly at the laser acupuncture of Well Point group. Conclusions : The laser acupuncture treatment in five transport points of the Heart Meridian was effective for lowering blood pressure, cardiac hypertrophy, Atherogenic index and HTR, and for enhancing antioxidant activity.

The anti-lipogenic effect of cereal samples on high sucrose diet (HSD)-induced non-alcoholic fatty liver disease (NAFLD) in mice was studied. We divided C57BL/6 mice into various groups based on 8 weeks of treatment with three types of cereal samples (HSD+WR, HSD diet containing 40% white rice; HSD+MCG, HSD diet containing 40% mixed cereal grain; HSD+AO-MCG, HSD diet containing 40% mixed antiobesity-cereal grain). After the experimental period, body weight changes, liver weights, serum lipid profiles, and hepatic fatty acid metabolism-related gene expression levels were determined. We found that HSD+WR, HSD+MCG, and HSD+AO-MCG treatments reduced body weight and liver weight, especially HSD+MCG and HSD+AO-MCG effectively reduced levels of serum triglycerides, total cholesterol, and low-density lipoprotein cholesterol. However, high density lipoprotein cholesterol levels increased compared to the control group. Furthermore, expression of hepatic lipogenic genes such as sterol regulatory element-binding protein-1c, acetyl-coenzyme A carboxylase, fatty acid synthase, stearoyl-coenzyme A desaturase-1, cluster of differentiation, and $PPAR-{\gamma}$ (peroxisome proliferator activated receptor ${\gamma}$) decreased, whereas expression of ${\beta}-oxidation$ genes such as $PPAR-{\alpha}$ and carnitine palmitoyl transferase-1 increased following HSD+MCG and HSD+AO-MCG treatment compared with levels in HSD+WR and control groups. These results suggest that the functional cereal samples, especially HSD+AO-MCG treatment, improved hepatic steatosis triggered by an HSD-induced imbalance in hepatic lipid metabolism.

In this study, we aimed to investigate the effects of dietary supplementation with fruiting body of Agaricus brasiliensis (AB) mushroom on the lipid profiles of serum and histological patterns of liver of high cholesterol-fed rats. Five-week-old, female Sprague-Dawley albino rats were divided into three groups of 8 rats each, including a normal control-diet (NC) group, a high-cholesterol diet (HC) group, and a group fed high-cholesterol diet supplemented with 5 % powder of Agaricus brasiliensis fruiting bodies (HC+AB). Total serum cholesterol, low density lipoprotein (LDL), and triglyceride (TG) concentrations in the HC+AB group were significantly reduced when compared with those in the HC group. Body weight in the HC+AB group was significantly lower than that in the HC group, whereas no adverse effects were observed on the levels of plasma albumin, creatinine, blood urea nitrogen, uric acid, glucose, and total protein. In the HC+AB group, liver enzyme activities related to liver function, such as GOT and GPT, presented values lower than those in the HC group and were very similar to the ones in the NC group. Excretion of total lipid and cholesterol in feces in the HC+AB group was significantly higher than that in the NC and HC groups, indicating that mushroom feeding inhibits the absorption of lipid cholesterol in the intestine. Liver histopathological analyses revealed that rats fed with HC diet developed fat liver disease, whereas only small amounts of fat were deposited in the livers of the HC+AB group. In conclusion, the results suggest that fruiting body powder of A. brasiliensis provides health benefits to high-cholesterol-fed rats by lowering body weight and the risk of atherogenic lipid profile.

Aims: To study alterations of plasma lipid profiles in carcinoma cervix and to assess significance comparedwith controls in different histological grades and stages. Materials and Methods: Totals of 99 histopathologically diagnosed cases and 35 controls from a tertiary hospital situated in the southern part of India which caters the rural and semi-urban populations were considered for the study. Fasting blood samples were taken to analyze total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C) and low density lipoproteins cholesterol (LDL-C), for comparison of cases, grouped according to histological grades and stages, and controls. One way ANOVA was used for multiple group comparisons and the Student's t test (unpaired) for group wise comparisons. For all tests a 'p' value of 0.05 or less was considered as significant. Results: Out of 99 cases, most (n-39) were seen in the 40-49 year age group followed by 60-69 years (n-22). Serum TG significantly differed between cases and controls but without any relation to differentiation grade. The lipid profile parameters in various grades of cervical cancer were not statistically significant. Statistically significant increase of TC and LDL-C values was observed with increase in stage of the disease. Conclusions: The study showed TG is elevated in cervical cancer, and that TC and LDL-C are proportional to the spread of cancer as it increases from stage I to stage IV. An in-depth study of molecular changes in lipid metabolism in cervical cancer patients, enzymes/genes responsible and alterations in LDL receptors is necessary to provide information to decide whether the lipid profile has any diagnostic/prognostic role in cervical cancer.

Cirsium japonicum var. ussuriense are often used in treatment of human diseases such as hemorrhage, blood congestion and inflammation in Korea. However, there was not report on the anti-obesity efficacy of water extracts from different organs of C. japonicum var. ussuriense. Here, we investigated the antioxidant effects of water extracts of flowers, leaves and roots from C. japonicum var. ussuriense. Total polyphenol amounts of the flower extract showed higher than those of leaf and root extract. Flower extract also showed the high antioxidant activities such as DPPH radical scavenging activity and reducing power. We also investigated the anti-obesity effects of water extracts of flowers, leaves and roots from C. japonicum var. ussuriense in 3T3-L1 cells and high fat diet-induced obesity mice. The mice were divided into four groups [high fat diet (HFD) control, HFD + leaf extract, HFD + flower extract and root extract] and administered with each extract (200 mg/kg) for 12 weeks. The flower and leaf extract significantly suppressed the levels of oil red O and triglyceride content. The flower and leaf extract also significantly reduced the triglyceride, total cholesterol and lower density lipoprotein levels of plasma as well as body and abdominal fat weight. Furthermore, oral glucose tolerance in the flower and leaf extract groups were significantly ameliorated in comparison to the high fat diet group. Therefore, these results indicate that the flower and leaf extract could ameliorate obesity and attenuate blood glucose level in high fat diet-induced obesity mice. We conclude that this study may provide positive insights into water extracts of flowers and leaves from C. japonicum var. ussuriense as a functional food ingredient for treatment of obesity.

Objectives: The purpose of this study was to investigate anti-obesity effect of Scutellariae Radix extract combined with metformin. Methods: Male C57BL/6 mice, 4 weeks of age, were used to set high-fat diet induced obesity model. They were grouped NOR (normal control), HFD (high fat diet control), MET (metformin, 100 mg/kg/day), MH2 (metformin 50 mg/kg/day+Scutellariae Radix 200 mg/kg/day), and HG4 (Scutellariae Radix 400 mg/kg/day). MET, MH2, and HG4 were orally administered for 10 weeks. Body weight was measured every week. Fasting blood glucose, triglyceride, total cholesterol (TC), high density lipoprotein, glutamic oxaloacetic transaminase (GOT), and glutamic-pyruvic transaminase (GPT) were measured before sacrifice. Oral glucose tolerance test (OGTT) was also performed. Organ weight and internal fat weight were measured after sacrifice. Results: MH2 group showed a reduction of body weight when compared with HFD group. MH2 group showed stable blood level control which was calculated areas under the curves by OGTT. TC, GOT, GPT level, internal fat, and organ weight in MH2 group reduced. Conclusions: The combined treatment of Scutellariae Radix and Metformin has impact on treating obesity. Further studies are needed to evaluate the effect of Metformin and herbal medicine combination therapy.

Purpose: This study was done to determine the effects of walking exercise training(WET) on metabolic syndrome risk factors and body composition in obese middle school girls. Method: A non-equivalent pretest-posttest experimental design was used. Twenty seven subjects participated in this study from one women's middle school in Busan. The participants were purposely allocated to an experimental group (n=14) and a control group (n=13). The experimental group participated in 30-60 minutes of WET with 55 to $75\%$ of a maximal heart rate six days a week for 12 weeks. Results: The prevalence of individual risk factors on metabolic syndrome were improved in the experimental group after the intervention. The high waist circumference(WC), high triglyceride(TG), low high density lipoprotein cholesterol(HDL-C), high blood pressure(BP) and high fasting glucose(FG) were 21.4, 21.4, 14.3, 28.6 and $7.2\%$, respectively. There were significant differences in WC (F=22.24, p<.001), TG (F=5.34, p=0.30), body weight(F=21.99, p<.001), fat mass(F=19.17, p<.001), and $\%$ body fat(F=17.93, p<.001) between the experimental and control group after the intervention. However, there were no significant differences in HDL-C, FG and BP between the experimental and control group after the intervention. Conclusion: These results indicate that WET is effective in decreasing risk factors of the metabolic syndrome and body composition components in obese middle school girls. These findings suggest that WET can be useful as a nursing intervention in the prevention of obesity-related disorders in obese adolescents.

Background: 3-Hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) effectively reduce serum levels of low-density lipoprotein (LDL) and total cholesterol. High-intensity statins are recommended for all patients aged ${\leq}75$ with clinical atherosclerotic cardiovascular disease (ASCVD), diabetes mellitus aged 40-75 with ${\geq}7.5%$ estimated 10-year ASCVD risk and LDL-C ${\geq}190mg/dL$. High-intensity statins associated with more frequent adverse events (AEs) compared to moderate- to low-intensity statins. The aim of this study was to compare AEs between high-intensity and moderate- to low-intensity statin group using the Korea Adverse Event Reporting System (KAERS) database. Methods: Adults (${\geq}18years$) with statin-associated AEs from July 2009-June 2014 were included. Only AEs classified as "certain", "probable" and "possible" based on the WHO-Uppsala Monitoring Center criteria were analyzed. Results: In total, 247 AEs from 196 patients [high-intensity statin group (HG), n = 25 (13%); moderate- to low-intensity statin group (MLG), n = 171 (87%)] were included. Mean age was higher in HG compared with MLG ($67{\pm}14$ vs $62{\pm}12$). The HG showed a significant higher frequency of liver/biliary system disorders (37% vs 14%, p = 0.001). Hepatic function abnormal was reported more frequently in HG compared to MLG (26% vs 9%, p = 0.006). Conclusion: According to KAERS data, liver/biliary system disorders were more frequently reported in HG compared to MLG.
