Background: Obesity, occurring at epidemic rates globally, is a major risk factor for DM and CVD. Despite advances in understanding its pathogenesis, the pharmacotherapy for obesity remains limited for achievable weight loss, safety and tolerability of the medicines. Almost all approved medications for long term use in obesity treatment result in health issues. Due to the ADRs associated with many antiobesity drugs, the drug trials have focused on screening herbal medicines that are reportedly used in the treatment of obesity and which have minimal side effects.Methods: In this study rats were divided into eight groups of six rats each. In the first approach, the rats were first made obese by feeding HFD for three weeks. In the second, treatment with the herbal extracts was given simultaneously with the HFD to the experimental rats. Rat were fed HFD for six weeks along with treatment of herbal extracts and the effect on their body weight, daily food intake and lipid-profile were evaluated.Results: Results showed that rats fed HFD for a six week period, supplemented with herbal preparations of triphala and G. cambogia presented with significant reduction in body weight, energy intake, and improved the lipid-profile as compared to the rats fed with HFD group.Conclusions: Our findings suggest that triphala and G. cambogia can counter the effects of HFD intake and have the potential for use as antiobesity agents with desirable body weight, food intake, fluid intake, and lipid-profile modulating properties.

Treatment Of Obesity

Whereas leptin administration only has a negligible effect on the treatment of obesity, it has been demonstrated that its action can be improved by co-administration of leptin and one of its sensitizers. Considering that oxytocin treatment decreases body weight in obese animals and humans, we investigated the effects of oxytocin and leptin cotreatment. First, lean and diet-induced obese (DIO) mice were treated with oxytocin for 2 weeks and we measured the acute leptin response. Second, DIO mice were treated for 2 weeks with saline, oxytocin (50 μg/day), leptin (20 or 40 µg/day) or oxytocin plus leptin. Oxytocin pre-treatment restored a normal acute leptin response, decreasing food intake and body weight gain. Chronic continuous administration of oxytocin or leptin at 40 µg/day decreased body weight in the presence (leptin) or in the absence (oxytocin) of cumulative differences in food intake. Saline or leptin treatment at 20 µg/day had no impact on body weight. Oxytocin and leptin cotreatments had no additional effects compared with single treatments. These results point to the fact that chronic oxytocin treatment improves the acute, but not the chronic leptin response, suggesting that this treatment could be used to improve the short-term satiety effect of leptin.

Introduction:Obesity is one of the most serious challenges of our era, with significant health consequences and high economic burden for health systems. Therefore, many countries have developed political agendas to cope with this ever-rising challenge. Along with chemical medications that are developed to manage obesity, researchers have focused on some natural ingredients and herbal extracts which are proved to be effective in reducing weight. The current study aimed to investigate the association between Foeniculum vulgar (fennel) extracts and body weight, lipid profile, and leptin. Methods: 35 adult male BALB/c mice were investigated, in sham, fennel 50 mg/kg, fennel 100 mg/kg, and fennel 200 mg/kg (n=7) groups. Mice were administered fennel extracts for fourteen days, while weighted at the beginning and the end of the intervention. Then, their weight, lipid profile, serum leptin, and expression of leptin protein in the hypothalamus were measured. Results: After providing the intervention, leptin receptor protein expression was increased in all groups, while serum leptin didn’t change significantly. Moreover, a significant decrease was observed in the cholesterol in the dose of 100 mg/kg/day, triglycerides in doses of 100 and 200 mg/kg/day, and LDL in doses of 50 and 100 mg/kg/day. Serum HDL was increased significantly in a dose of 100 mg/kg/day. Conclusion: Fennel extract can decrease the lipid profile by changing the expression of the leptin receptor.

Sites Of Action

The glucagon-like peptide-1 receptor (GLP-1R) agonist liraglutide is approved for the treatment of obesity; however, there is still much to be learned regarding the neuronal sites of action that underlie its suppressive effects on food intake and body weight. Peripherally administered liraglutide in rats acts in part through central GLP-1Rs in both the hypothalamus and the hindbrain. Here, we extend findings supporting a role for hindbrain GLP-1Rs in mediating the anorectic effects of liraglutide in male rats. To dissociate the contribution of GLP-1Rs in the area postrema (AP) and the nucleus tractus solitarius (NTS), we examined the effects of liraglutide in both NTS AAV-shRNA–driven Glp1r knockdown and AP-lesioned animals. Knockdown of NTS GLP-1Rs, but not surgical lesioning of the AP, attenuated the anorectic and body weight–reducing effects of acutely delivered liraglutide. In addition, NTS c-Fos responses were maintained in AP-lesioned animals. Moreover, NTS Glp1r knockdown was sufficient to attenuate the intake- and body weight–reducing effects of chronic daily administered liraglutide over 3 weeks. Development of improved obesity pharmacotherapies requires an understanding of the cellular phenotypes targeted by GLP-1R agonists. Fluorescence in situ hybridization identified Glp1r transcripts in NTS GABAergic neurons, which when inhibited using chemogenetics, attenuated the food intake– and body weight–reducing effects of liraglutide. This work demonstrates the contribution of NTS GLP-1Rs to the anorectic potential of liraglutide and highlights a phenotypically distinct (GABAergic) population of neurons within the NTS that express the GLP-1R and are involved in the mediation of liraglutide signaling.

Objective: The objective of the study was to evaluate the toxicological potential of the ethanolic extract of leaves of Mirabilis jalapa linn through acute and subacute toxicity studies in albino Wistar rats. Methods: For acute toxicity studies, the ethanolic extract of M. jalapa was given up to 2000 mg/kg and then the animals were observed for 14 days to find out any adverse effect or death. For sub-acute toxicity studies, the exact was given for 28 days and the following parameters were observed such as changes in body weight, food intake, water intake, hematological parameters, biochemical parameters, lipid profile, urine analysis, and histopathological studies were undertaken. Results: Single oral administration of 2000 mg/kg of the ethanolic extract of M. jalapa produced no mortality or signs of toxicity. During subacute toxicity there were no changes in body weight, food intake and water intake were observed. There were no changes in lipid profile, hematological parameters, and biochemical parameters. In histopathological changes, there were no structural changes in treated groups when compared to control. Conclusion: The leaves of ethanolic extract of M. jalapa is safe when administered for 28 days. There were no deaths or signs of toxicity in treated rats during acute toxicity studies and subacute toxicity studies.

The anti-obesity activity of ethanol extract of the stem bark of Thespesia populnea L., (EETP) was evaluated in High Fat Diet (HFD) induced obese rats and flavonoid isolated of Quercetin was characterized. Acute oral toxicity studies revealed that EETP is safe up to 2000mg/kg and doses were selected. Six groups of rats were used and administered orally with vehicle 0.2ml of 1% tween 80 (normal control), fed on HFD+0.2ml of 1% tween 80 (negative control), fed on HFD+EETP (100, 200 & 400 mg/kg) and fed on HFD+ Orlistat 50 mg/kg (positive control), for 40 days respectively. The body rectal temperature, food intake, Lee index and body weight of the animals were recorded and the whole brain was dissected out for estimation of serotonin on day 41. The blood samples were collected by cardiac puncture and used for the estimation of lipid profile. The atherogenic and coronary risk indices were calculated from lipid profile. Obese rats pretreated with EETP or Orlistat exhibited significant increase in body rectal temperature and decrease in food intake, Lee index and body weight of the animals. Moreover, the tested extracts showed beneficial effects on brain serotonin, lipid profile, atherogenic and coronary risk indices in rats. In conclusion, EETP exerts potential anti-obesity activity that could be partly attributed to its flavonoid Quercetin and other bioactive phytoconstituents.

Abstract Agouti-related peptide (AgRP) neurons of the hypothalamus play a key role in regulating food intake and body weight, by releasing three different orexigenic molecules: AgRP; GABA; and neuropeptide Y. AgRP neurons express various G protein-coupled receptors (GPCRs) with different coupling properties, including Gs-linked GPCRs. At present, the potential role of Gs-coupled GPCRs in regulating the activity of AgRP neurons remains unknown. Here we show that the activation of Gs-coupled receptors expressed by AgRP neurons leads to a robust and sustained increase in food intake. We also provide detailed mechanistic data linking the stimulation of this class of receptors to the observed feeding phenotype. Moreover, we show that this pathway is clearly distinct from other GPCR signalling cascades that are operative in AgRP neurons. Our data suggest that drugs able to inhibit this signalling pathway may become useful for the treatment of obesity.

SummaryAfter seven generations of selection, a line of mice selected for post-weaning (21–42 days) weight gain on full feeding (SF) showed significant increases of 49% in weight gain, 31% in efficiency and 14% in food intake, when compared with its control on full feeding between 21 and 42 days. After day 42, SF mice continued to eat more food and were 28% heavier than control mice at 91 days. Because SF mice were heavier than control mice at almost all ages, they were fatter on an age basis. There was, however, no change in the rate of deposition of fat, protein and ash relative to body weight. On restricted feeding between 21 and 42 days, SF mice showed a non-significant increase in weight gain, and hence in efficiency, of 12%. They deposited more fat than control mice during the feeding period but there was no significant difference when comparisons were made on a weight basis.A contemporary line of mice selected for post-weaning (21–42 days) weight gain on restricted feeding (SR) had significant increases of 12% in weight gain, 17% in efficiency but no significant change in food intake, when compared with its control on full feeding between 21 and 42 days. SR mice were the same weight as control mice at all ages except day 21, when they were significantly lighter due to direct genetic effects rather than maternal effects. SR mice had a lower (P<0·10) rate of fat deposition per unit body weight and became less fat relative to their control as body weight increased. The rate of deposition of other components was not altered by selection. On restricted feeding, SR had a significant increase in weight gain, and hence in efficiency, of 37%. Changes in body composition were similar to those on full feeding.It was concluded that the use of a restricted feeding regime had enabled the exploitation of heritable variation in the partitioning of energy for growth. This variation was independent of genetic variation for appetite and body weight.Overall performance at each level of feeding was best improved by selection on that feeding level. The realized genetic correlation between post-weaning weight gain on full and restricted feeding was estimated to be 0·28 ± 0·08, indicating a very different genetic basis for the same character in the two feeding environments.

Abstract Objectives Androgenic alopecia is characterized by a receding hairline and hair loss from the frontal scalp. This genetic condition affects approximately 80% of men and 42% of women. Finasteride is the only oral treatment currently approved by the FDA to prevent and treat androgenic alopecia, and it is currently prescribed to over nine million males in the US. Recent claims suggest that long-term use of finasteride could have detrimental health effects by affecting the lipid profile in people. Finasteride prevents the conversion of testosterone to its active metabolite dihydrotestosterone by inhibiting the type II 5 alpha-reductase, which is predominantly present in the hair follicle and the prostate. As a result, finasteride alters the systemic levels of testosterone and its derivative estradiol. Hormone homeostasis affects plasma lipid levels, therefore we hypothesize that supplementation with finasteride will affect systemic lipid profile in atheroprone low-density lipoprotein receptor (Ldlr−/−) mice fed a Western diet (high cholesterol, high fat). Methods We fed six-week-old male Ldlr−/-mice (10/group) fed a Western diet (control) or a Western diet supplemented with 10 mg Finasteride/kg diet for 12 weeks. We monitored body weight progression and food intake during the entire experiment. A week before harvesting the tissues, mice were fasted overnight to perform a glucose tolerance test. At the moment of sacrifice, final body weight and several tissues were collected such as the inguinal, retroperitoneal, and gonadal adipose tissues, skeletal muscle (gastrocnemius), and liver. Plasma was harvested to determine total cholesterol and triglyceride levels. Results Our data show that 12-week supplementation with a low dose of finasteride does not have a significant impact on food intake, body weight, or adiposity index. We did not observe any significant change in plasma lipids or glucose tolerance. Conclusions A low dose of finasteride supplemented for 12 weeks does not alter the lipid profile in the atheroprone Ldlr−/-mouse model, nor alters adiposity index. These data indicate that finasteride does not have detrimental effects on these metabolic parameters. Funding Sources U.S. Department of Agriculture (Multi-State grant project W4002).

The prevalence of overweight and obesity is increasing in children and adolescents worldwide raising the question on the approach to this condition because of the potential morbidity, mortality, and economic tolls. Dietetic and behavioral treatments alone have only limited success; consequently, discussion on strategies for treating childhood and adolescent obesity has been promoted. Considering that our knowledge on the physiological systems regulating food intake and body weight is considerably increased, many studies have underlined the scientific and clinical relevance of potential treatments based on management of peripheral or central neuropeptides signals by drugs. In this paper, we analyze the data on the currently approved obesity pharmacological treatment suggesting the new potential drugs.
