Objectives: This study investigated the effects of water extract of Aconitum carmichaeli Debx (ACD) on obesity and glucose tolerance in high fat diet induced obese mice. Methods: Five-week-old C5BL/6 mice were fed a high fat diet (HFD) containing or not containing ACD (100 or 300 mg/kg) for 16 weeks. Body weight, food intake, fasting blood glucose, and body temperature were checked every week and then organs, blood serums were collected after 16-week treatment. Furthermore oral glucose tolerance test (OGTT) was carried out after treatment. Results: ACD treated mice showed no significant decreases in body weight and adipose tissue weight as compared with HFD mice. Lipid accumulations in liver and serum lipid levels were not different between ACD treated and HFD mice. However, ACD extract administration significantly and dose-dependently reduced fasted plasma glucose and glucose tolerance as determined by OGTT. Conclusions: The present study demonstrates that ACD might prevent diet-induced glucose tolerance in mouse models of obesity.

Using high-fat diet-induced obese (DIO) mice, the mechanism of anti-adiposity and anti-obesity actions produced by Inonotus obliquus water extract (IOE) was investigated. Significant reduction in body weight in DIO mice orally administrated with IOE for 8 weeks compared to IOE-non-treated control mice was observed, which was attributed to the reduction of epididymal and mesenteric adipose tissue, but not the liver and skeletal muscle. Adiponectin synthesis in epididymal adipose tissue (EAT) and AMPK phosphorylation in the liver were significantly increased in IOE-treated DIO mice. Gene expression analysis showed that IOE-treated DIO mice had higher expression levels of lipogenic genes in EAT and fatty-acid oxidative genes in the liver, but lower expression levels of hepatic pro-inflammatory cytokines compared to IOE-non-treated controls. Our findings confirm a therapeutic potential of Inonotus obliquus for reducing adiposity and ameliorating hyperlipidemia to treat metabolic disorders.

Vitamin C (ascorbic acid) supplementation has been suggested to negatively correlate with obesity in humans and other animals. Previous studies, including ours, have demonstrated that a high-fat diet (HFD) induces obesity and related diseases such as hyperlipidemia, hyperglycemia, insulin resistance, and nonalcoholic fatty liver disease. Here, we investigated the effects of vitamin C on visceral adipocyte hypertrophy and glucose intolerance in C57BL/6J mice. Mice received a low-fat diet (LFD, 10% kcal fat), HFD (45% kcal fat), or the same HFD supplemented with vitamin C (HFD-VC, 1% w/w) for 15 weeks. Visceral adiposity and glucose intolerance were examined using metabolic measurements, histology, and gene expression analyses. Mice in the HFD-VC supplementation group had reduced body weight, mesenteric fat mass, and mesenteric adipocyte size compared with HFD-fed mice. Vitamin C intake in obese mice also decreased the mRNA levels of lipogenesis-related genes (i.e., stearoyl-CoA desaturase 1 and sterol regulatory element-binding protein 1c) in mesenteric adipose tissues, inhibited hyperglycemia, and improved glucose tolerance. In addition, vitamin C attenuated the HFD-induced increase in the size of pancreatic islets. These results suggest that vitamin C suppresses HFD-induced visceral adipocyte hypertrophy and glucose intolerance in part by decreasing the visceral adipose expression of genes involved in lipogenesis.

In this study, we investigated the anti-obese activity of sevennight extract in high fat diet-ob/ob C57BL/6J mice by oral administered for 1 weeks. Mate water extract (MATEWi) was found to lower whole body and epididymal adipose tissue weights and lowered plasma levels of triglyceride (TG) and total cholesterol (TC), HDL and LDL, compared to those in high fat fed ob/ob group. These results suggest that Mate extract ameliorates obesity through activation of lipogenic enzymes and FA oxidation resulting from phosphorylation of AKT and GSK-$3{\beta}$, and could be developed as a potential therapeutic agent for obese mices.

Obesity is a critical health issue in Korea, where half of all adults are overweight and a third obese. Aronia melanocarpa -rich in flavonoids and phenolics- with antioxidant and anti-inflammatory activities, could have anti-obesity activity and reduce body fat mass by upregulating lipolysis and β-oxidation in obese mice. Male C57BL/6J mice (n=12) were assigned into four groups: normal chow (18% kcal from fat); high-fat diet control (HFD, 45% kcal from fat); HFD+A. melanocarpa (200 mg/kg diet); HFD+Xenical (500 mg/kg diet, positive control). Antioxidant capacity of A. melanocarpa was established in vitro and in vivo. Weight loss was induced as decreased adiposity and lowered respiratory quotient at rest suggested oxidation of stored fat. Adiposity reduction, accompanied with elevated fat utilization, was owing to enhanced activity of hormone-sensitive lipase. Thus, A. melanocarpa lowered adiposity by enhancing lipolysis and utilization of fatty acids in visceral fat.

We investigated anti-hyperglycemic and anti-obese effects of Panax ginseng berry extract and its major constituent, ginsenoside Re, in obese diabetic C57BL/6J ob/ob mice and their lean littermates. Animals received daily intraperitoneal injections of Panax ginseng berry extract for 12 days. On Day 5, 150 mg/kg extract-treated ob/ob mice had significantly lower fasting blood glucose levels compared to vehicle-treated mice $(156{\pm}9.0\;mg/dl\;vs.\;243{\pm}15.8mg/dl,$ P<0.01). On Day 12, the extract-treated ob/ob mice became normoglycemic $(137{\pm}6.7\;mg/dl)$ and had significantly improved glucose tolerance. The overall glucose excursion during the two-hour intraperitoneal glucose tolerance test (IPGTT), calculated as area under the curve (AUC), decreased by $46\%$ (P<0.01) compared to vehicle-treated ob/ob mice. Glucose levels of lean mice were not significantly affected by the extract. The improvement in blood glucose levels in 150 mg/kg extracttreated ob/ob mice was associated with significant reduction in serum insulin levels of fed and fasting mice. Consistent with an improvement in insulin sensitivity, hyperinsulinemic euglycemic clamp study revealed a more than 2-fold increase in the rate of insulin-stimulated glucose disposal in treated ob/ob mice $(112{\pm}19.1\;vs.\;52{\pm}11.8{\mu}mol/kg/min$ for the vehicle group, P<0.01). In addition, 150 mg/kg extract-treated ob/ob mice, but not the lean mice, lost significant weight (from $51.7{\pm}1.9g\;on\;Day\;0\;to\;45.7{\pm}1.2$ on Day 12, P<0.01 compared to vehicle-treated ob/ob mice), associated with a significant reduction in food intake (P<0.05) and a very significant increase in energy expenditure (P<0.01) and body temperature (P<0.01). A 12-day treatment with 150 mg/kg Panax ginseng berry extract also significantly reduced plasma cholesterol levels in ob/ob mice. Additional studies demonstrated that ginsenoside Re, a major constituent of the ginseng berry, but not from the root, plays a significant role in anti-hyperglycemic action. This anti-diabetic effect of ginsenoside Re was not associated with body weight changes, suggesting that other constituents in the extract have distinct pharmacological mechanisms on energy metabolism. The identification of a significant anti-hyperglycemic activity in ginsenoside Re may provide an opportunity to develop a novel class of anti-diabetic agent.
