Objectives : The present study was designed to investigate the anti-diabetic effects of Mori Folium (Morus alba L. of Moraceae) extract (MFE) on high fat diet (HFD) and streptozotocin (STZ)-induced type II diabetes mellitus in mice. Methods : The mice (C57BL/6J) were fed HFD for 8 weeks and then was induced with a single injection of STZ (75 mg/kg). The diabetic mice were divided into four groups [(STD, HFD, HFD + MFE and HFD + quercetin (QUR)] and administered with MFE or OUR for 4 weeks. Fasting blood glucose, lipid profile (triglycerides and cholesterol etc.), glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), insulin and leptin were measured every 2 weeks. Results : Body weight gain was lower in the MFE and QUR groups than HFD group. The fasting blood glucose was lower in the MFE and QUR groups. Oral glucose and insulin tolerance were decreased in the MFE and QUR groups. The levels of serum total cholesterol, triglycerides, and LDL cholesterol were reduced in the MFE and QUR groups. The HDL cholesterol was much higher in the MFE and QUR groups than HFD group. The levels of GOT, GPT and atherogenic index were decreased in the MFE and QUR groups. The serum insulin and leptin concentrations were reduced in the MFE and QUR groups. Conclusions : These results showed that MFE could decrease blood glucose level and lead to an amelioration in dyslipidemia states on HFD/STZ-induced type II diabetes mellitus in mice.

Objective : The aim of the present study is to examine hepatic lipid-lowering and anti-inflammatory effects of silymarin combined with Jakyakgamcho-tang on non-alcoholic fatty liver disease in a high fat diet-induced obese mice model. Methods : C57BL/6 mice were divided into four dietary groups: (1) Normal, (2) Control (60% high-fat diet), (3) Control + silymarin 50 mg/kg/day (Silymarin), (4) Control + Silymarin 50 mg/kg/day + Jakyakgamcho-tang 100 mg/kg/day (SPG). After 12 weeks administration, mice were sacrificed and lipids and inflammation-related biomarkers were analyzed liver and plasma. Results : Silymarin and SPG treatments significantly lowered body and liver weights compared to the Control. Serumlipids (triglyceride (TG), total cholesterol) and pro-inflammatory cytokines (tumor necrosis factor alpha, interleukin 1𝛽, and IL-6) concentrations were significantly lowered in the Silymarin and SPG groups than the Control group. Silymarin and SPG treatments suppressed hepatic TG level and hepatic lipid droplets compared to the Control. Theses two treatments significantly increased hepatic kinase B1 and AMP-activated protein kinase protein levels, and significantly decreased hepatic key lipogenic enzymes (acetyl-CoA carboxylase, fatty acid synthase and stearyl coenzyme A desaturase 1) protein levels than the Control. SPG also significantly increased hepatic fatty acid oxidation-related protein (peroxisome proliferator-activated receptor alpha and uncoupling protein 2) levels than the Control. Conclusions: Silymarin and SPG suppressed hepatic lipid accumulation by regulating hepatic protein expression, and lowered blood pro-inflammatory cytokines concentrations though the synergic effect of silymarin and Jakyakgamchotang was not clear.

The objective of this study was to investigate the anti-obesity effects of adding Momordica charantia (MC) and Chrysanthemum zawadskii var. latilobum (CZ) extracts to drinking water on obesity-induced mice. A total of 84 eight-week-old C57BL/6N male mice with an initial body weight (BW) of 28.11 ± 1.39 g were used in this study. All treatments were fed a high-fat diet for d 28. Mice were randomly divided into seven drinking treatments (six replicate each treatment) based on the initial BW. Treatments are as follows: control (CON), normal tap water, MC 1, CON with 1% MC aqueous extract, MC 2, CON with 2% MC aqueous extract, CZ 1, CON with 1% CZ aqueous extract, CZ 2, CON with CZ aqueous extract (2%), MCZ 1, CON with 1% MC aqueous extract and 1% CZ aqueous extract, MCZ 2, CON with 2% MC aqueous extract and 2% CZ aqueous extract. During the entire period, the CZ 1, MCZ 1, and MCZ 2 significantly decreased (p < 0.05) gain to feed than CON. The CON significantly higher (p < 0.05) water intake than other treatments on d 0 to 14. The MCZ 1 significantly decreased (p < 0.05) relative (ratio of absolute organ weight to BW) organ weights, including retroperitoneal white adipose tissue (RWAT) weight and inguinal white adipose tissue (IWAT) weight, compared to CON. In conclusion, our study suggests that there was no significant difference in the anti-obesity effects between MC and CZ, and MCZ 1 has synergistic effects by regulating adipose tissue.

In the present study, we examined the effects of interleukin (IL)-10 expression-inducing bacteria Bifidobacterium adolescentis HP1, Lactobacillus mucosae HP2, and Weissella cibaria HP3 on high-fat diet (HFD)-induced obesity and liver steatosis in mice. Oral gavage of HP1, HP2, and HP3 reduced HFD-induced bodyweight gain, triglycerides, and total cholesterol levels in the blood and liver. They also suppressed HFD-induced colitis and the fecal δ,γ-Proteobacteria population. Of the tested bacteria, HP2, which most potently inhibited IL-10 expression, also suppressed HFD-induced bodyweight gain, liver steatosis, and colitis most effectively. These findings suggest that IL-10 expression-inducing gut bacteria can suppress obesity and liver steatosis.

Objectives: Schizandrae fructus (Schizandra chinensis) is one of very common herbs, it is known as natural antioxidants, anti-inflammatory agent. Also some reports show that its extract works to regulate of dyslipidemia. This study was designed to investigate the effects of Schizandrae fructus chloroform fraction (SFCF) on serum lipid levels in dyslipidemic mice. Methods: The levels of total cholesterol, high density lipoprotein-cholesterol, triglyceride, aspartate aminotransferase (AST), alanine aminotransferase (ALT), fasting blood glucose in serum were measured. Histopathological and gene expression changes in liver tissue were also observed. Results: Oral administration of SFCF lowered levels of total cholesterol and triglyceride, which were elevated by high-fat diet. But SFCF did not affect on weight changes and serum AST, ALT levels in dyslipidemic mice. After carrying out gene ontological analysis, large numbers of genes in high-fat diet group were up-(347) or down-regulated (235). In SFCF treated mice, some changed expression of the genes was restored to normal levels, with a recovery rate of 17%. And it seems that fatty acid biosynthesis pathway was one of important key pathways to recovery. Conclusions: SFCF has beneficial effect on dyslipidemia, and could be used to prevent and treat cardiovascular disease.

The effect of buckwheat dietary fiber (BDF) as hypolipidemic and antioxidant agent were determined in C57BL/6 mice fed a high fat diet (HFD) with different doses of 500 (low, BDF-L) or 1,000 (high, BDF-H) mg/kg of body weight, compared with the HFD-diet control group (HFD). The negative control group (ND) was fed the basal diet. Body weights in the BDF-L and BDF-H groups were significantly decreased as compared to those in the HFD group (p<0.05). BDF also improved the lipid profile in a dose-dependent manner; serum lipid profiles and levels of insulin, glucose, and free fatty acid were significantly decreased in the BDF-L and BDF-H groups, whereas HDL-C and adiponectin significantly increased as compared to the HFD group (p<0.05). Meanwhile, BDF lowered serum malondialdehyde (MDA) in comparison with the HFD group (p<0.05). The results demonstrate that the intake of BDF might prevent obesity and its related metabolic disorders by inducing dyslipidemia and oxidative stress.

Objectives : This comparative study was to investigate on anti-obesity effects of Ephedrae Herba and Cyperi rhizoma in high fat diet(HFD) fed mice. Methods : Male C57BL/6J mice were fed a normal diet(normal group, N), high fat 45 cal% diet[HFD, control group, C), HFD with Ephedrae Herba(EH group) and Cyperi rhizoma(CR group) extracts fed for 5 weeks. We were observed as follows : changes of body weight, amount of diet intake, weight of total visceral fats, levels of obesity-related hormones and blood lipids. Results : The change of body weight after EH and CR oral administration significantly more decreased in EH group than that of control group. The FFR(Food Efficiency Ratio) was decreased in EH group, but more increased in CR group than that of control group. The weight of periepididymal and perirenal fats were significantly decreased in EH and CR groups compared to the control group. The levels of serum leptin and insulin were significantly decreased in EH group, and the level of serum adiponectin was increased in EH group compared to control group. The levels of serum triglyceride and total cholesterol were significantly decreased in EH and CR groups, and HDL-cholesterol levels was significantly increased in EH group compared to control group. Conversely in CR group, its values showed the opposite effect. The staining density of lipid droplets within the hepatocytes was widely distributed in CR and control groups, but in EH group, its density was weakly stained. Conclusions : These experimental results suggest that Ephedrae Herba shows conspicuous anti-obesity effect, and Cyperi rhizoma shows weak anti-obesity effect.

The objective of this study was to evaluate the effects of Lactobacillus acidophilus ATCC 43121 and L. fermentum MF27 on biochemical indices in the serum, cholesterol metabolism in the liver and mucin expression in the gallbladder in lithogenic diet (LD)-induced C57BL/6J mice to determine the preventive effects of lactobacilli on gallstone formation. By the end of 4 wk of the experimental period, mice fed on a LD with high-fat and high-cholesterol exhibited higher levels of total and low-density lipoprotein cholesterol in the serum compared to mice fed on control diet or LD with L. acidophilus ATCC 43121 (LD+P1; p<0.05). Cholesterol-lowering effects observed in the LD+P1 and LD with L. fermentum MF27 (LD+P2) groups were associated with reduced expression of 3-hydroxy-3-methylglutaryl coenzyme A reductase in the liver compared to the LD group (p<0.05). Furthermore, expression of the gel-forming mucin, including MUC5AB and MUC5B, was suppressed in the LD+P1 and LD+P2 groups compared to the LD group (p<0.05). Therefore, steady intake of both L. acidophilus ATCC 43121 and L. fermentum MF27 may have the ability to prevent the formation of cholesterol gallstones in LD-induced C57BL/6J mice.

Obesity is psychological and socioeconomic problems as well as health problems related to physical disease and disorder. The obesity epidemic, including a marked increase in the prevalence of obesity among pregnant women, represents a critical public health problem throughout the world. Gung-Gui-Tang (GGT), a prescription of traditional Korean medicine, has been used to treat dizziness due to loss of blood as well as static blood after childbirth. However, the therapeutic potential of GGT on postpartum obesity has not been fully elucidated in an experimental model. In our research, GGT inhibited the increases of body weight and adipose tissues in postpartum mice fed a high-fat diet. GGT also inhibited the elevations of plasma lipid profiles such as triglyceride, low-density lipoprotein cholesterol, total cholesterol, and glutamate pyruvate transaminase. Overall, these results provide evidence that GGT can help to inhibit postpartum obesity and open new perspective to recover the shape of mother into the moment of conception.

Lactic acid bacteria are representative probiotics that have beneficial effects on humans. Nineteen strains among the 167 single strains from kimchi was selected and their physiological features were investigated. The selection of a strain was based on strong enzyme (lipase, α-amylase, and α-glucosidase) inhibitory activities and anti-obesity effects in the adipocytes. For the final selection, the strain Lactiplantibacillus plantarum KC3 was tested for its potential as a starter. To assess its functionality, a freeze-dried culture of L. plantarum KC3 was administered to a diet-induced obese mouse model receiving a high-fat diet. The animal group administered with L. plantarum KC3 showed significant body weight loss during the 12-week feeding period compared to the high-fat control group. This study investigated the physiological characteristics of selected strain and evaluated its potential as an anti-obesity probiotic in mice.
