Objective: This study was undertaken to investigate the effects of Mori folium on insulin resistance and adipose tissue inflammation in an experimental mouse model of obesity.Methods: Obesity was induced in C57BL/6 mice by feeding them a high-fat diet. The mice were divided into four groups (n=6): a normal diet, high-fat diet, high-fat diet with 40 mg of Mori folium, and high-fat diet with 800 mg of Mori folium groups. After 13 wk, the body weights, fasting blood glucose and fasting serum insulin levels, insulin resistance (homeostatic model assessment) levels, oral glucose tolerance test levels, epididymal fat and liver weights, and gene expression of tumor necrosis factor-α, interleukin-6, and interferon-γ were measured. In addition, adipose tissue macrophages were analyzed by fluorescence-activated cell sorting.Results: Mori folium significantly reduced blood glucose levels, oral glucose tolerance levels, and liver weights. It also reduced adipose tissue macrophage numbers and tumor necrosis factor receptor-α gene expression.Conclusions: These results show that Mori folium has insulin resistance reduction and anti-inflammatory effects in an experimental mouse model of obesity.

Objectives: This study was undertaken to investigate how Cortex Phellodendri affects metabolic functional change in an experimental rat model of obesity.Methods: An obesity model was induced in a C57BL/6 mouse with a high-fat diet. Mice were divided into three groups (n=6) of normal diet, high-fat diet (=control), and high-fat diet with Cortex Phellodendri. After 12 weeks, we measured the three mice groups’ body weight, FBG, FBI, HOMA-IR, OGTT, the weight of epididymal fat and liver, the percentage of ATM, and the gene expression of TNF-α, IL-10, and CD68.Results: Cortex Phellodendri significantly reduced blood glucose and oral glucose tolerance levels. It also reduced ATM numbers and TNF-α and CD68 gene expression and increased IL-10 gene expression.Conclusions: This study suggests that Cortex Phellodendri normalized the blood glucose and reduced the expression of inflammatory markers. However, with respect to other indicators of metabolic function in obesity, there were no significant results.

Background: The rising prevalence of asthma may be associated with the rising prevalence of obesity in developed nations. There are several studies showing that obesity increases the risk of asthma in adults. We investigated the association of each body composition scale and bronchial hyper-responsiveness. Methods: This study involved a retrospective review of the existing records for 279 subjects with respiratory symptoms, who underwent a pulmonary function test, a methacholine challenge test and a body composition test between May 2007 and June 2009. Results: Of the 279 subjects, 179 (64%) were female. There was a statistically significant difference in fat free mass and in fat free mass index between the normal bronchial responsiveness group and bronchial hyper-responsiveness group (p=0.036; p=0.000). There was no significant differences in body mass index, in fat mass and fat free mass index in the normal bronchial responsiveness group and bronchial hyper-responsiveness group in males. However in females, body mass index and fat free mass index were increased in the bronchial hyper-responsiveness group (p=0.044; p=0.000). Total body water (kg), fat free mass (kg) and soft lean mass (kg) were significantly different between the normal bronchial responsiveness group and bronchial hyper-responsiveness group (p=0.002; p=0.000; p=0.000). Conclusion: This study showed significant differences in fat free mass and in fat free mass index between the normal bronchial responsiveness group and the bronchial hyper-responsiveness group. In females, BMI, soft lean mass, and total body water showed significant differences between the normal bronchial responsiveness group and the bronchial hyper-responsiveness group. We concluded that bronchial hyper-responsiveness was associated with not only body mass index but also fat free mass index in female bronchial asthma.

Objectives: Obesity is an important cause of insulin resistance that leads to obese type 2 diabetes. Recently it has been found that obesity is associated with adipose tissue accumulation which causes systemic inflammation. In this study, we investigated effects of Inula helenium on the inflammation in high fat diet-induced insulin resistance mouse. Methods: Insulin resistance was induced in C57BL/6 male mice (19~21 g) on a 60% fat diet. Mice were divided into 3 groups (n=6) of normal, control and Inula helenium. After 12 weeks, body weight, FBS, oral glucose tolerance test (OGTT), serum level of insulin, epididymal fat pad, liver weight and the gene expression of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6, interleukin (IL)-10 and cluster of differentiation (CD) 68 were measured. Also, adipose tissue macrophage was analyzed by fluorescence activated cell sorting. Results: Inula helenium significantly reduces oral glucose tolerance levels, insulin serum level and adipose tissue macrophage. Also Inula helenium increased IL-10 gene expression and decreased CD68 gene expression. Conclusions: These results show that Inula helenium has anti-insulin resistance and anti-inflammatory effects on a high fat diet-induced insulin resistance mouse model.

Background : Obesity, the syndrome caused by a high fat diet, is a disease. At the same time, obesity causes diabetes mellitus, hyperlipidemia, and cardiovascular disease. Recently, its prevalence rate is increasing. Yagwan-cheunghyeoltang (YCT) used in this experiment is the prescription of Yagwanmoon added to Cheunghyeol-tang which is reported to be very effective in weight loss controlling and serum cholesterol. It is also reported that Yagwanmoon has significant antioxidant effects and YCT has a significant effect on blood glucose control. Objectives : This study was conducted to experimentally evaluate the effects of YCT on obesity in rats induced by high fat diet. Methods : The experiment was conducted with 4-week-old male rat s divided into 5 groups. They were a normal diet group, a high fat diet group, a positive drug control group, a 1% YCT group, and a YCT 3% group, and were tested for eight weeks. After four weeks of inducing obesity by a high fat diet, rats were allowed to lose weight by following the normal diet group, approximately 30% compared with 10 rats in each group were determined as still obese. Changes in body weight and organ weight and serum cholesterol, triglyceride, glucose-density, low density lipoprotein cholesterol, antioxidant activity were checked. Results : In the experimental groups, we observed weight loss and visceral fat reduction, improvement of liver function, reduction of serum glucose, activation of HMG-CoA reductase inhibitor, reduction of concentrations of leptin and it showed a significant effect on antioxidants and lipid peroxidation. Conclusions : YCT has significant effects on the regulation of hyperlipidemia and lipid peroxidation associated with obesity and has significant effects on, antioxidants and lipid peroxidation, too. Additional clinical studies are needed.

The fat-forming variant of solitary fibrous tumors (SFTs) is a rare soft tissue neoplasm that was previously referred to as a lipomatous hemangiopericytoma (L-HPC). The most common affected site is deep soft tissue. Here, we present the first case, worldwide, of a fat-forming variant of SFT of the pleura. A 74-year-old man presented with left lower chest pain. Chest radiographs showed a mass-like lesion at the left lower lung field and chest computed tomography revealed a 12 cm fat-containing enhancing mass that was well-separated, lobulated and inhomogeneous. Radiology findings suggested a liposarcoma. Percutaneous needle biopsy was performed and pathological diagnosis of the mass was a fat-forming variant of SFT. Surgical resection was carried out and there has been no recurrence to date. So, a benign fat-forming variant of SFT must be considered as one of the differential diagnoses of lipomatous tumors of the pleura.

Objectives: Recent data have revealed that the plasma concentration of inflammatory mediators is increased in the insulin-resistant states of obesity and type 2 diabetes. The purpose of this study was to investigate the antidiabetic and anti-obesity effect of Massa Medicata Fermentata on obese type 2 diabetes mice. Methods: In order to examine the effects of Massa Medicata Fermentata, obese type 2 diabetes mice induced by Surwit's high fat, high sucrose diet. Mice were divided into 4 groups of ND (normal diet), HFD (high fat and high sucrose diet), Met (high fat and high sucrose diet with metformin) and MMF (high fat and high sucrose diet with Massa Medicata Fermentata) and investigated over 8 weeks. Diabetic and obese clinical markers, including body weight, glucose level, lipid level, leptin concentration, epididymal fat pad and liver weights and adipose tissue macrophage (ATM) were determined. Results: Compared with the HFD group, body weight, fructosamine, triglyceride, epididymal fat pad weight and ATM were significantly reduced in the MMF group. Conclusions: From the above results, the intake of Massa Medicata Fermentata may be effective in anti-hyperglycemia and anti-obesity by the attenuation of glucose and lipid levels and also inflammation state. Massa Medicata Fermentata may be beneficial for controlling diabetes mellitus type 2 in humans.

We have evaluated the application of spectroscopy using an insertion-type fiber-optic probe and a sensor at wavelengths from 400 to 1,100 nm to the measurement of milk fat content on dairy farms. The internal reflectance ratios of 183 milk samples were determined with a fiber-optic spectrophotometer at 5$^{\circ}C$, 20$^{\circ}C$ and 40$^{\circ}C$. Partial least squares (PLS) regression was used to develop calibration models for the milk fat. The best accuracy of determination was found for an equation that was obtained using smoothed internal reflectance data and three PLS factors at 20$^{\circ}C$. The correlation coefficients between predicted and reference milk fat at 5$^{\circ}C$, 20$^{\circ}C$ and 40$^{\circ}C$ were r=0.753, r=0.796 and r=0.783, respectively. The predictive explained variances ($Q^2$) of the final model, moreover, were more than 0.550 at all temperatures, and the regression coefficients of determination ($R^2$) were more than 0.6 (60%). Our results indicate that milk has different internal reflectance measured in the range of visible and near infrared wavelengths (400 to 1,100 nm), depending on its fat content.

Fat embolism syndrome (FES) is a clinical manifestation that consists of multiple organ dysfunction due to fat emboli. FES occurs as a complication after trauma or procedures such as surgery. The diagnostic criteria of FES have not yet been established, so clinical criteria are used for its diagnosis. The clinical course of acute fulminant FES can be rapid. Liposuction surgery, in which adipocytes are mechanically disrupted, is one cause of FES. As the number of liposuction surgeries increases, clinicians should be aware of the possibility of FES. This was the first report of a case of acute fulminant FES with severe acute respiratory distress syndrome after liposuction surgery, in Korea.
