Capsaicin is a pungent component of red pepper, which is widely consumed as food adjuncts. The present study was performed to investigate anti-obesity effects of capsaicin in diet-induced obese rats. Male Sprague-Dawley rats (n=14) were fed with a high-fat diet (Control) or high-fat diet containing 0.016% capsaicin (w/w) (Capsaicin) for 8 weeks. The final body weight and the mass of white adipose tissue were significantly lower in capsaicin supplemented group compared to control. Dietary capsaicin ameliorated lipid profiles with decrease in the plasma concentrations of triglycerides and total cholesterol, and decrease in the levels of total lipids and triglycerides in the liver. Activity of glycerol-3-phosphate dehydrogenase (GPDH), an indicator of triglyceride biosynthesis in white adipose tissue, decreased by 35% in the group supplemented with capsaicin. However, consumption of capsaicin increased the expression of uncoupling protein 2 (UCP2) in white adipose tissue, which is related to energy consumption. Our data suggests that capsaicin may reduce body weight and fat accumulation in high fat diet-induced obese rats. These effects may be mediated, at least partially, by the upregulation of UCP2 gene expression and its ability to inhibit GPDH activity.
Objectives: The objective of this study is to investigate the effects of Silbi-um (SBU) extract on the alcoholic fatty liver induced by EtOH administration for 8 weeks. Methods: Male Sprague Dawley rats were used. All animals were randomly divided into 3 groups; Normal, EtOH and EtOH+SBU. The rats of EtOH group were daily treated with ethanol of 25% (v/v) for 8 weeks (n=10). EtOH+SBU group was orally treated with SBU water extract after ethanol administration (n=10). The rats of Normal group were treated with saline (n=10). After 8 weeks, the mean body weight, liver weight, and liver-body weight ratio were calculated. The serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) of all groups were measured. The morphological alterations were observed using hematoxylin and eosin (H&E) and Oil Red O staining. Moreover, the alteration of tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) levels were analyzed immunohistochemistrically. Results: The histological data showed that liver sections from EtOH group displayed severe steatosis. SBU extract significantly inhibited the progression of the alcoholic liver injury. The increased serum level of ALT and AST induced by ethanol administration were decreased by SBU extract. Furthermore, SBU extract significantly decreased the liver concentrations of $TNF-{\alpha}$. Conclusions: SBU water extract attenuated the alcohol induced fatty liver by improving hepatic lipid metabolism via suppression of $TNF-{\alpha}$ protein. SBU could be effective in protecting the liver from alcoholic fatty liver.
BACKGROUND/OBJECTIVES: Obesity is a global health problem of significant importance which increases mortality. In place of anti-obesity drugs, natural products are being developed as alternative therapeutic materials. In this study, we investigated the effect of Brassica juncea L. leaf extract (BLE) on fat deposition and lipid profiles in high-fat, high-cholesterol diet (HFC)-induced obese rats. MATERIALS/METHODS: Male Sprague-Dawley rats were divided into four groups (n = 8 per group) according to diet: normal diet group (ND), high-fat/high-cholesterol diet group (HFC), HFC with 3% BLE diet group (HFC-A1), and HFC with 5% BLE diet group (HFC-A2). Each group was fed for 6 weeks. Rat body and adipose tissue weights, serum biochemical parameters, and tissue lipid contents were determined. The expression levels of mRNA and proteins involved in lipid and cholesterol metabolism were determined by reverse transcription polymerase chain reaction and western blot analysis, respectively. RESULTS: The HFC-A2 group showed significantly lower body weight gain and food efficiency ratio than the HFC group. BLE supplementation caused mesenteric, epididymal, and total adipose tissue weights to decrease. The serum levels of triglyceride, total cholesterol, and low-density lipoprotein cholesterol were significantly reduced, and high-density lipoprotein cholesterol was significantly increased in rats fed BLE. These results were related to lower glucose-6-phosphate dehydrogenase, acetyl-coA carboxylase, and fatty acid synthase mRNA expression, and to higher expression of the cholesterol $7{\alpha}$-hydroxylase and low density lipoprotein-receptor, as well as increased protein levels of peroxisome proliferator-activated receptor ${\alpha}$. Histological analysis of the liver revealed decreased lipid droplets in HFC rats treated with BLE. CONCLUSIONS: Supplementation of HFC with 3% or 5% BLE inhibited body fat accumulation, improved lipid profiles, and modulated lipogenesis- and cholesterol metabolism-related gene and protein expression.

This present study was carried out to investigate the body weight-regulatory effects of Chekamhanghyuluiyiin-tang plus Zeae Stigma in high fat diet-induced obese rats. Control group rats were fed with high fat diet and administered normal saline for 8weeks. Experimental groups rats were fed with high fat diet and administered extract of 2 kind of Chekamhanghyuluiyiin-tang plus Zeae Stigma each other for 8 weeks. And observed that, body weight of rats and total cholesterol, triglyceride, free fatty acid, total lipid, phospholipid, high density lipoprotein(HDL)-cholesterol, low density lipoprotein(LDL)-cholesterol in serum of rats, and glucose, insulin of rats. The results were as follows; 1. There were significant decrease of serum total cholesterol level in 7CH10 group. 2. There were significant decrease of serum total lipid level in 7CH5 group. 3. There were significant decrease of serum total lipid level in 7CH5 group. According to above mentioned results. Chekamhanghyuluiyiin-tang plus Zeae Stigma was expected to be applied to the prevention or treatment of obesity and its complications.
The antiobesity effect of commercial kochujang and fermented wheat grains in Sprague-Dawley (SD) rats was studied. The experiment was consisted of 6 groups. Normal, high fat diet (HFD), HFD+raw wheat grains, HFD+first fermented wheat grains (FFWG, with Aspergillus oryzae) HFD+final fermented wheat grains (FiFWG, fermented more for 30~40 days), and HFD+ commercial kochujang. The results showed that final body weight, weight gain, food efficiency ratio, and adipose tissue weight were markedly decreased by the commercial kochujang and the fermented wheat grains, whereas non-fermented raw wheat grains had no such effect. Lipid contents such as total lipid, total triglyceride and total cholesterol decreased in the serum and organs of liver and adipose tissues by the commercial kochujang and the fermented wheat grains as well. These results also indicated that fermented wheat grains exhibited more suppressive effects on high fat induced-obesity than raw wheat grains. Increased fermentation time and adding the red pepper powder resulted in increased the anti-obesity effect. Especially, commercial kochujang showed higher antiobestic effects than fermented wheat grains. These in vivo findings suggested that well-fermented end products of the wheat grains and red pepper powder in kochujang could be useful in the prevention of obesity.

The purpose of this study is to examine how to relate with hypothalamus protein BDNF and mRNA leptin expression, and test the effect of exercise training upon anti-obesity in high-fat induced obese rats. Weight and plasma TC of the high-fat diet group (HF) significantly reduced in comparison to those in the high-fat diet and training group (HF-T), high-fat diet and normal diet group (HF-ND), and high-fat diet, training, and normal diet group (HF-ND+T) (P<0.05). Plasm TG of the HF group significantly decreased in comparison to the HF-ND+T group (P< 0.05). The plasma leptin level significantly reduced in the HF-T group in comparison to the HF group, in the HF-ND group compared to the HF-T group, and the HF-ND+T group in comparison to the HF-ND group (P<0.05, respectively). All groups were significantly increased in hypothalamus BDNF protein expression in comparison to the HF group. In hypothalamus leptin mRNA expression, the HF-T and HF-ND groups reduced, but the HF-NF+T group increased in comparison to the HF group. This result suggests that it shows the effect of exercise training upon anti-obesity in high-fat diet induced obese rats and the combined exercise and/or normal diet may affect the optimal obesity improvement and prevention in appetite and weight control.

Obesity can be defined as a metabolic disease due to an increased fat accumulation in the body caused by an imbalance of calorie intake and output The prevalence of obesity has increased substantially over the past 2-3 decades in developed and developing countries. The health impact of weight gain is so marked that obesity has now been classified as a major global public health problem In order to investigate the effect of diet conversion and oral administration of Platycodon grandiflorum extracts on the treatment of obesity, male Spraque-Dawley rats were divided into four groups: a group converted to normal diet (Control group), a group maintained high fat (30%) diet (H), and two groups with Platycodon grandiflorum extract added to the previously mentioned two groups. All animals were fed high fat diet for 7 weeks to induce the obesity. Then they were divided as mentioned above. Animals were fed experimental diet and Platycodon grandiflorum extract (150 mg/ml/rat/day) for 7 weeks. Body weight, adipose tissue weight (subcutaneous, epididymal, peritoneal fat pads) and serum lipids (total cholesterol and triglyceride) showed some differences among groups. The Platycodon grandiflorum feeding markedly decreased both body weight and adipose tissue weight in control group compared to H, high fat diet maintaining, group. Platycodon grandiflorum extracts significantly decreased the concentrations of serum lipids compared to H group. Fat cell numbers and sizes were significantly reduced in the oriental medicinal herb extract administrated group. Increased fatty acid binding protein (FABP) expression in high fat diet group was decreased by the dietary conversion to normal diet and the oral administration of Platycodon glandiflorum extracts. In contrast, there was no significant effect on FABP expression in the high fat maintenance group. In this study, the conversion from high fat diet to low fat or normal diet had a beneficial effect on body weight loss and serum lipid profiles. Dietary Platycodon glandiflorum extracts had an additive beneficial effect on the prevention and treatment of obesity.

This experimental study was designed to investigate the inhibitory effects of ethanol extract of modified Yukgunja-tang(mYGJT) on high-fat diet-induced obesity and hyperlipidemia in Sprague-Dawley rats, Animals were divided into normal, control, mYGJT(100 mg/kg and 200 mg/kg) treated groups. Obesity with hyperlipidemia was induced by high fat diet treatment for 6 weeks. mYGJT was given to the amimals by oral gavage for 4 weeks, starting at the high-fat diet regimen, The effect of mYGJT on the differentiation of 3T3 L1 adipocytes in vitro and serological paramamters for obesity and hyperlipidemia in vivo were evaluated, mYGJT significnatly inhibited the differentiation of 3T3 L1 adipocytes in a concentration dependent manner. mYGJT treatment siginficantly reduced body weight, abdominal and epididymal fat weight, and FER(Food Efficiency Ratio) compared with control group in a dose dependent manner. It also signficantly inhibited the levels of serum total lipid, triglyceride, phospholipid, total cholesterol, LDL, AI(Atherosclerosis Index) and returned the serum HDL to normal. Total lipids, triglycerides and cholesterols in the liver, as well as malondialdehyde(MDA) and hydroxy radical in the serum were significantly reduced. However, superoxide dismutase(SOD) activity was significantly increased in mYGJT treated group compared with control group. Finally, mYGJT treatment signficantly decreased the MDA and protein carbonyl concentrations of the hepatic homogenate but signficantly increased the activities of SOD, GSH-Px and Catalase. Taken together, these results suggest that mYGJT can be clinically useful in inhibiting high-fat diet-induced obesity and hyperlipidemia.

This experimental study was performed to evaluate the effects of ehtanol extract of Purple Solanum tuberosum L(EPSTL) on obesity and hyperlipidemia in rats induced by high fat diet. Sprague-Dawley rats were divided into normal group, control group, EPSTL (100 mg/kg and 200 mg/kg) treated group. EPSTL was orally administered to the obese rats by high fat diet for 6 weeks. The effect of EPSTL on obesity and hyperlipidemia were examined in vitro and in vivo as follows : EPSTL effectively inhibited the differentiation of 3T3-L1 adipocytes in a concentration dependent manner. EPSTL significantly lowered body weight of rats fe high fat diet for 6 weeks from 4 weeks treatment compared with untreated control. EPSTL significantly reduced the weight of retroperitoneal fat only at 100 mg/kg and epididymal fat pad in rats fed high fat diet for 4 weeks at 100 and 200 mg/kg. EPSTL significantly reduced the level of triglyceride at 200 mg/kg, while EPSTL tended to lower the levels of total lipid and phospholipid in rats fed high fat diet for 4 weeks with no significance. EPSTL significantly attenuated the level of total cholesterol, LDL and atherosclerosis index (Al) as well as increased the level of HDL at 200 mg/kg. EPSTL significantly reduced the levels of total lipid and triglyceride of hepatic tissues in rats fed high fat diet for 4 weeks at 200 mg/kg. EPSTL significantly lowered the level of insulin, while it did not affect leptin compared with untreated control. Taken together, these results suggest that EPSTL can be used for the treatment or prevention of hyperlipidemia and obesity.
