Antidiabetic and antihyperlipidemic activities of a novel polyherbal formulation in high fat diet/streptozotocin induced diabetic rat model.

OBJECTIVE: To investigate the antidiabetic and antihyperlipidemic activities of polyherbal formulation (PHF) containing hydroalcoholic extracts of four plants namely Salacia oblonga, Salacia roxbhurgii, Garcinia indica and Lagerstroemia parviflora in streptozotocin (STZ)-induced diabetic rats by administering oral doses (200 and 400 mg/kg body weight). MATERIALS AND METHODS: Animals were divided into diabetic and nondiabetic groups. Rats were fed with a high-fat diet (HFD) and induced with a single low dose of STZ (35 mg/kg) i.p. Diabetic rats were treated with formulation (200 and 400 mg/kg) and metformin 250 mg/kg. Blood glucose levels were measured using blood glucose test strips with ACCU CHEK glucometer. Lipid profile and gluconeogenic enzymes were determined in normal and STZ-induced diabetic rats after oral administration of the PHF for 28 days. Histopathological changes in diabetic rat organs (pancreas, liver, and kidney) were also observed after PHF treatment. RESULTS: Treatment of diabetic rats with PHF and metformin decreased plasma glucose and lipid profile levels. Blood glucose level showed significant reduction after 28 days of treatment with formulation at 200 and 400 mg/kg and in metformin. Formulation treated rats showed significant (P < 0.001) decrease in the activities of gluconeogenic enzymes. Histological examination of various organ tissues of normal control, diabetic control, and drug-treated rats revealed significant results. Treatment with PHF reverses the most blood and tissue changes toward the normal level. CONCLUSION: These findings suggested the antihyperglycemic and antihyperlipidemic properties of the PHF and thus help in preventing future complications of diabetes.

Evaluation of plant based formulation on adolescent obesity and its associated bio-markers: a randomized, double blind, placebo controlled study.

OBJECTIVE: Obesity and overweight are the fifth most fatal diseases leading to an increased rate of morbidity and mortality in global population, with its incidence increasing drastically. Taking this into consideration we have conducted the present study in order to explore the efficacy of plant based formulation in the management of adolescent obesity and its associated biomarkers. DESIGN: Randomized, double blind, placebo controlled trial was conducted in 130 obese adolescent of both sexes, with BMI above 25kg/m(2). The subjects were randomly assigned into test formulation group (TFG) and placebo group (PG). TFG received two 500mg capsule containing test formulation whereas, the PG received two 500mg of cellulose powder containing capsule daily for 3 months. The parameters such as blood pressure, inflammatory cytokines, adipokines and lipid profile were assessed in all subjects pre and post treatment. RESULTS: There was a considerable improvement in the levels of lipid profile, inflammatory cytokines, adipokines and blood pressure after treatment in TFG compared to PG. The statistical difference obtained between the groups after three months of treatment for the various biomarkers are given as mean with 95% CI for BMI (-1.4±0.6 (-2.5 to -0.7)), total cholesterol mg/dl (-20.9±5.0 (-30.8 to -11.0)), triglyceride mg/dl (-12.9±5.7 (-23.9 to -1.2)), HDL-c mg/dl (7.2±0.8 (5.6-8.8)), IL-6 (-0.7±0.1 (-0.9 to -0.6)), hs C-reactive protein (CRP) mg/l(-1.0±0.01 (-1.2 to -0.8)), adiponectin µg/ml(4.9±0.4 (4.2-5.7)), leptin ng/ml (-8.0±1.4 (-10.7 to -5.3)), diastolic blood pressure (DBP) mmHg (-10.4±0.8 (-12.0 to -8.7)) and systolic blood pressure (SBP) mmHg (-6.7±0.7 (-8.1 to -5.3)). Also, there was a statistical significance within group TFG. CONCLUSION: The study concludes that the test formulation may prevent the future cardio vascular risk incidence in obese adolescents by reducing inflammation, overweight, lipid profile and by regulating adipokines. Thus it may help to improve the health pattern in obese patients with least side effects.
