This study was investigated the effect of aerobic exercise and chrysin supplementation on macrophage infiltration and lipolysis in high-fat diet mice. To accomplish the purpose of this study, C57BL/6 mice were fed high fat diet(60% fat diet) during experimental period. The animals were divided into 4 groups; NC (normal diet control, n=5), HC (high fat diet control, n=5), Hch(high fat diet with chrysin, n=5), and HME (high fat diet with aerobic exercise training, n=5). Exercise training was performed for 16 weeks on a treadmill running. As a result, macrophage marker, F480 and CD11c were significantly decreased in HME comparison with HD and Hch. Also, M2 macrophage marker CD11c, and lipolysis marker PRDM were significantly increased in HME compared with HC and Hch These findings suggest that regular aerobic exercise has beneficial effects to inhibit macrophage infiltration in high fat diet mice.

Purpose: It has been previously reported that breast tumor incidence, growth, and metastasis are stimulated by high-fat diet but reduced by caloric restriction. However, few studies have elucidated the effects of dietary change from a high-fat diet after breast cancer initiation. Therefore, in this study, we attempted to provide practical assistance to breast cancer prevention and management by investigating the effects of dietary change from a high-fat diet to normal diet on breast cancer growth and metastasis. Methods: The experimental animals were divided into 2 groups (high-fat diet control [HFC] group and diet restriction [DR] group) and consumed a high-fat diet for 8 weeks. 4T1 cells were transplanted into subcutaneous fat or tail vein to measure the growth and metastasis of breast cancer. The HFC and DR groups continuously ingested either high-fat diet or AIG-93G diet for 5 weeks or 3 weeks, respectively. Cell proliferation and apoptosis markers from tumor tissues were analyzed by Western blot analysis. The data were analyzed using the SPSS 25.0 package program. Results: The results show that the DR group significantly reduced breast tumor initiation, growth, and tumor tissue weight compared to the HFC group. The DR group suppressed tumor growth by decreasing proliferation and inducing apoptosis through down-regulation of Bcl-xL and up-regulation of caspase-3 activity. Furthermore, the DR group significantly reduced numbers of metastasized tumors in lung tissues. Conclusion: These results suggest that dietary change from a high-fat diet to normal diet decreased breast growth by reducing cell proliferation and inducing apoptosis and metastasis. Taken together, these results indicate that dietary change to a low-fat and balanced diet might suppress breast tumor growth and metastasis even after tumor diagnosis.

Objectives The aim of this study was to determine the inhibitory effects of Bangpungtongsungsan extract (BTS) on fat accumulation in high-fat diet-induced young obese mice. Methods The extract was administered to 3-week-old C57BL/6 male mice fed with a high-fat diet. The experimental groups were divided into a control group (Ctrl), high-fat diet group (HFDF), and BTS treated group after high fat diet feeding (BTST), with 10 mice assigned to each group. Lipid synthesis was observed to confirm the inhibition of fat synthesis. Changes in body weight, body fat percentage, and total cholesterol in the blood were observed to confirm weight control. Peroxisome proliferator-activated receptor gamma (PPAR-γ) and sterol regulatory element-binding protein (SREBP)-1 positivity was observed to confirm the inhibition of fat accumulation in liver tissue. Results Bangpungtongsungsan significantly inhibited lipid synthesis. Changes in body weight, body fat percentage, and total cholesterol in the blood were significantly lower in BTST rats than in HFDF rats. PPAR-γ and SREBP-1 positivity were significantly lower in BTST rats compared to HFDF rats. Conclusions This study confirms the potential of BTST to inhibit fat accumulation in obesity.

This study was undertaken to know the effect of fat diet (for eight weeks) on changes of inflammatory markers [tumor necrosis factor (TNF-${\alpha}$) and prostaglandin $E_2$ ($PGE_2$)] and blood coagulation system [platelet aggregation function (PAF), prothrombin time (PT), activated partial thromboplastin time (aPTT)] in rats. Serum TNF-${\alpha}$, $PGE_2$, biochemical markers, PAF, PT, aPTT, and body weight were measured and compared between the control (normal diet-rats) and the fat group (fat diet-rats). The weights in the fat group were higher than those of the control group. TNF-${\alpha}$, $PGE_2$, glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and creatinine levels were greater in the fat group compared with the control group. The degree of platelet aggregation was lower, whereas PT and aPTT levels were longer in the fat group than in the control group. These findings have shown that fat diet may cause inflammatory response, diabetes, liver and renal dysfunction, and disturbances of fibrinolysis and coagulation system.

This study was carried out to investigate the effect of Lythrum salicaria L. ethanol extract on anti-obesity effects in rat fed a high fat diet for 8 weeks to induce obese rat model. Male SD rats were divided into normal group, control (high fat diet) group, positive control (Garcinia Cambogia extracts) group, high fat group supplemented with ethanol extracts of Lythrum salicaria L. (EELS). The body weight gain and control (high fat diet) were increased by a high fat diet, but decreased in the EELS. At the end of the experiment, the body weight in high fat diet groups was higher than that of normal diet group, while the body weights of EELS and positive control group were significantly reduced by 16.62%, as compared with that of high fat diet group (p < 0.05). The levels of serum triglyceride, total cholesterol in EELS group were significantly decreased as compared with high fat diet group (p < 0.05). The liver and mesenteric adipose tissue weights of control (high fat diet) increase than that for normal group, whereas EELS and positive control group were significantly decreased (p < 0.05). Levels of triglyceride in liver were significantly lower in EELS group than those in high fat diet group (p < 0.05). These results indicate that Lythrum salicaria L. extract may improve lipid metabolism and reduce fat accumulation and body weight.

Effect of kochujang (Korean red pepper soybean paste) on the reduction of body weight and lipid levels of adipose tissues and serum were investigated in the rats fed a high-fat diet. Male Sprague-Dawley rats were fed for four weeks with diets containing either a normal diet (ND, based on the AIN-76TM diet), high fat diet (HFD, supplemented with 20% corn oil in ND), CK diet (10% commercial kochujang in HFD), TK I diet (10% 0 day (non-) fermented traditional kochujang in HFD), TKII diet (10% 6-month fermented traditional kochujang in HFD), or RPP diet (3% red pepper powder in HFD). CK, TK I and TKII in the diet significantly reduced the body weight gain compared to the control (HFD), whereas red pepper powder had no such effect. TKII supplementation in the high-fat diet reduced epididymal and perirenal fat pad weight significantly (p<0.05). Liver total lipid was lower in TKII diet group than other kochujang and RPP diet groups. TKII and CK decreased the content of triglyceride in epididymal and perirenal fat pad that increased by high-fat diet. The cholesterol content of the perirenal fat pad was the lowest in the TKII diet group. TKII was also effective in lowering serum cholesterol level. These results indicated that properly ripened (fermented for 6-month) traditional kochujang exhibited more suppressive effects on body fat gain and lipid levels of adipose tissue and serum than RPP, commercial kochujang and the kochujang without fermentation.

The effects of capsaicin, a pungent principle of hot red pepper, on body fat gain, balance serum lipid values were investigated in rats fed a high-fat(30%) diet. Administration of capsaicin by dietary administration caused a complete cessation of increased in body weight and fat gain induced by the high-fat diet. However, energy intake and body protein gain were not affected by capsaicin. Therefore, the suppression of body fat gain by capsaicn was believed due to an increased in energy expenditure. Simultaneous administration of capsaicin and a $\beta$-adrenergic blocker, propranolo, resulted in the inhibition of changes in body fat gain by capsaicin without remained unchanged, indicating an increase in the number of mitochondria in brown adipose tissue. Therefore, it appears that capsaicin possesses potent body fat suppressive effects mediated by $\beta$-adrenergic stimulation in which brown adipose tissue may be involved. On the other hand, capsaicin had no effects on serum triglyceride, total cholesterol or HDL-cholesterol levels. These results are in contrast to those reported by other investigators. Perhaps expression of the effects of capsaicin on plasma lipids is a rather complicated process, dependent on the type of diet administered, fat content of the diet, period and route of capsaicin administration, and species and strain of animals used.
