Background: Dyslipidaemia is an important risk factor for development of macrovascular complications in type 2 diabetes mellitus. Ocimum sanctum (OS) and metformin have shown to have antihyperlipidaemic effects. The present study was undertaken  to evaluate the effects of  OS and Metformin on body weight & plasma lipid  levels of high fat diet fed diabetic ratsMethods: Total of 30 male wistar  rats (100-150gm) were obtained. Animals were fed with a high fat diet throughout the study (6 weeks). Diabetes was induced by using single intra-peritoneal injection of Streptozotocin 50mg/kg at the end of 4 weeks.  Diabetic rats were divided into groups of 6 each and treated as follows: Group 1- Diabetic control, was given vehicle orally. Group 2- O.S. ethanolic extract 100mg/kg body weight orally for 14 days. Group 3- O.S. ethanolic extract  200mg/kg body weight orally for 14 days. Group 4-  Metformin 100mg/day for 14 daysResults: At the end of 4 weeks, body weight of rats were significantly increased (p <0.05). Maximum weight gain was seen in control group whereas weight gain was least in O.S. 200mg/kg group (p >0.05). Decrease in body weight was seen in metformin group. Abdominal circumference of rats also showed similar pattern (p >0.05).  OS 200 caused significant reduction in serum LDL levels (p <0.05) and significant rise of serum HDL levels (p <0.05) as compared to control group. Metformin also favourably affected the lipid profile and its effects were not significantly different from effects of OS 200 (p> 0.05).Conclusions: Present study revealed that Ocimum Sanctum caused significant reduction in serum lipid levels in high fat diet fed diabetic rats. Metformin  also exhibited antihyperlipidaemic activity. So, it is concluded that OS or metformin alone or in combination  could be a novel adjunct to diet and life style modification for the management of dyslipidaemia in type 2 diabetes.  Further studies are required to confirm the antidyslipidaemic activities of individual phytoconstituents of Ocimum sanctum.

 Objective: This study was carried out to investigate the potential of Dunaliella salina microalgae to ameliorate obesity induced by high-fat diet (HFD) in male Wistar rats.Methods: Fifty rats weighing 150–160 g were fed HFD for 12 weeks. The rats were randomly divided into five groups of ten rats each. Obese rats were orally administered D. salina ethanolic extract (150 mg/Kg body weight), and orlistat as standard drug (12 mg/Kg body weight), for 6 weeks.Results: Treatment of obese rats with both D. salina and orlistat had a significant effect in reducing body and liver weights as well as visceral fat, inhibiting pancreatic lipase activity, decreased lipid profile, and increased fecal fat and ameliorating liver function enzymes activity, insulin, blood glucose, and leptin levels. Besides, food intake was insignificantly increased as a result of D. salina and orlistat treatments compared with normal control rats.Conclusion: It could be concluded that D. salina rich in β-carotene significantly reduced body weight gain and ameliorated several metabolic pathways implicated in obesity and its related complication. Hence, further intensive study must be carried out to formulate D. Salina extracts to apply as a promising natural anti-obesity nutraceutical drug.

Background: Dietary high fat possibly causes oxidative stress. Also, it alters the pathophysiology of metabolically active myocardial tissues and vascular architecture. Emblica officinalis contains a potential antioxidant that counteracts oxidative stress and possibly maintains vascular integrity. Objective: To assess the effect of ethanolic extract of Emblica officinalis (EEO) on High Fat Diet (HFD) induced changes in vascular chemistry and histopathology of the cardiovascular system in male albino rats. Materials and Methods: Ethanolic extract of Emblica Officinalis (EEO) was prepared and phytochemical analysis was done. Rats were divided into four groups, having six rats in each group as follows: group 1- Control (20% fat); group 2 (20% fat+ EEO 100 mg/kg/b w); group 3 (30% fat) and group 4 (30% fat + EEO 100 mg/kg/b w). Dietary and EEO supplementation was continued for 21 days. Gravimetric and oxidative stress markers like MDA, NO, antioxidants like Vitamin C and E, and molecular marker (NOS3) were evaluated. Histopathological analysis was done on the myocardium and elastic artery along with measurement of coronary arterial wall thickness and lumen diameter. One way ANOVA was done for analysis of data. Results: High fat diet showed a significant increase in MDA, decrease of NO with unaltered NOS3 protein in rats fed with high fat diet, which indicate possible alteration of vascular pathophysiology. Supplementation of EEO showed an ameliorating effect on high fat diet induced oxidative stress. These results were further corroborated with findings of a histopathological study on the myocardium, elastic artery and coronary arterial architecture. Conclusion: Ethanolic extract of Emblica officinalis (EEO) indicates its cardioprotective efficacy against rats fed with high fat diet.
