The effect of ethanol extract of the fruiting bodies of Pleurotus ostreatus on serum lipid profile  and atherogenic indices of high sucrose high fat diet streptozotocin (HS-HFD-STZ) induced diabetic rats was determined by standard methods. All the groups were fed high sucrose-high fat diet except the normal group. The Metformin HCl and ethanol extract was given once daily by gavage to the reference and experimental groups respectively at doses of 150mg/Kg b.w., 50mg/Kg   b.w, 150mg/Kg b.w. and 300mg/Kg b.w. respectively while the normal control received saline solution.  The HDL-cholesterol level was higher than the value of the disease group after 6 weeks of administration of extract at 300mg/kg and after 9 weeks administration of extract at 150mg/kg. HDL cholesterol concentration increased by 22.2% after 6 weeks of extract administration at 300mg/kg and by 16.7% and 28.3% respectively after 9 weeks of extract administration at 150mg/kg and 50mg/kg respectively, indicating that the POE extract has the capacity to reduce cardiovascular diseases. At all the doses of extract administered for treatment at 3 weeks, 6 weeks and 9 weeks intervals, there was dose and time dependent lowering of LDL: HDL ratio even below the recommended risk limit of ≤ 2.5 compared to the test control with value above 2.5. After 3 weeks of treatment with extract at administration concentration level of 150mg/kg, atherogenic indices were lowered and extract levels of 150mg/kg and 300mg/kg reduced atherogenic index value after 6 weeks of administration while after 9 weeks of treatment, extract at 150mg/kg concentration reduced atherogenic indices. The atherogenic indices of the diabetic animals under treatment were dose-and time dependently reduced by POE treatment as observed in this study.These results suggest a possible use of the extracts in the management of hyperlipidemic conditions, hypertension and associated complications.

Abstract Introduction This study evaluates the anti-diabetic effect of ethanol extract of Stachytarpheta jamaicensis leaf on streptozotocin (STZ) - induced diabetic rats fed on high-fat diet (HFD). Methods Sets of male albino rats of the Wistar strain weighing between 180 and 250 g were exposed to high fat diet (margarine and oil from vegetable sources in a ratio of 2:1 w/v) for 3 weeks. Then the animals were fasted overnight; hyperglycemic state was induced using reduced dose of streptozotocin (35 mg/kg) and animals were randomly divided into five groups (n = 7); group A received the HFD + STZ (35 mg/kg i.p.); group B received HFD + STZ + gliberclamide (10 mg/kg; i.p); groups C, D and E were administered the HFD + streptozotocin with different doses of the ethanol extract (30, 35 and 100 mg/kg p.o., respectively). Results Results showed significant (p < 0.05) decrease in blood glucose concentration of the rats treated with different doses of S. jamaicensis extract and those treated with gliberclamide compared to the untreated diabetic rats (negative control). Significant (p < 0.05) reductions in activities of serum AST, ALP, total protein and bilirubin were noticed in the groups in contrast to the control. Levels of urea, creatinine, potassium and chloride were considerably (p < 0.05) low while sodium and bicarbonate levels were high in the groups except the control. Lipid profile revealed significant (p < 0.05) reduction in total cholesterol, triacylglycerol, LDL, VLDL while HDL levels were high in the groups compared to the control. The extract significantly (p < 0.05) ameliorated weight loss. Histopathology of the liver, kidney and pancreas showed ameliorative effect of the extract against the deleterious changes occasioned by the HFD and STZ induced diabetic state. Conclusion These findings have provided scientific basis for the use of S. jamaicensis in the treatment of diabetes mellitus in ethnomedicinal practices in Nigeria.

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.

Type 2 Diabetic

Type 2 diabetes was induced by feeding with high-sucrose-high-fat diet and injecting 25mg/kg streptozotocin. Rats were randomly divided into three groups: control, diabetic, diabetic simultaneously injected ip with Ginkgo biloba extract (EGb) for 8 wk. The treatment of EGb attenuated the development of hyperglycemia and hyperinsulinemia in type 2 diabetic rats. The serum levels of cholesterol, triglyceride as well as the activities of alanine aminotransferase, aspartate aminotransferase were significantly decreases in EGb-treated rats. The level of malondialdehyde were significantly increased in diabetic rats and decreased after EGb administration. Moreover, EGb markedly increased the activities of superoxide dismutase, catalase and glutathione peroxidase in liver. The results indicate that EGb has a protective effect on liver of type 2 diabetic rats, which may be related to decreases the accumulation of cholesterol, triglyceride in liver and its antioxidant property.

Aims. To determine the effect of partial replacement of a high-fat diet with menhaden oil on diabetic neuropathy in an animal model of type 2 diabetes.Materials and Methods. High-fat/low-dose streptozotocin diabetic rats were used to examine the influence of replacing 50% of the source of the high-fat diet (lard) with menhaden oil, a natural source of n-3 fatty acids, on diabetic neuropathy. Endpoints included analyses of glucose tolerance, fatty liver disease, serum and liver fatty acid composition, serum lipid and adiponectin levels, motor and sensory nerve conduction velocity, thermal sensitivity and innervation of the hindpaw.Results. Diabetic rats were insulin resistant and menhaden oil did not improve whole animal glucose utilization. Menhaden oil did not improve elevated HbA1C levels or serum lipid levels but serum levels of adiponectin were significantly increased and hepatic steatosis was significantly improved. Diabetic rats were thermal hypoalgesic, had reduced motor and sensory nerve conduction velocities and intraepidermal nerve fiber profiles were decreased in the hindpaw and these endpoints were significantly improved with menhaden oil.Conclusions. We found that enrichment of a high-fat diet with menhaden oil improved a number of endpoints associated with diabetic neuropathy.

Abstract. Objective: This study aimed to evaluate the effect of maternal consumption of flaxseed flour and oil on serum concentrations of glucose, insulin, and thyroid hormones of the adult female offspring of diabetic rats. Methods: Wistar rats were induced to diabetes by a high-fat diet (60%) and streptozotocin (35 mg/kg). Rats were mated and once pregnancy was confirmed, were divided into the following groups: Control Group (CG): casein-based diet; High-fat Group (HG): high-fat diet (49%); High-fat Flaxseed Group (HFG): high-fat diet supplemented with 25% flaxseed flour; High-fat Flaxseed Oil group (HOG): high-fat diet, where soya oil was replaced with flaxseed oil. After weaning, female pups (n = 6) from each group were separated, received a commercial rat diet and were sacrificed after 180 days. Serum insulin concentrations were determined by ELISA, the levels of triiodothyronine (T3), thyroxine (T4) and thyroid-stimulating hormone (TSH) were determined by chemiluminescence. Results: There was a significant reduction in body weight at weaning in HG (−31%), HFG (−33%) and HOG (44%) compared to CG (p = 0.002), which became similar by the end of 180 days. Blood glucose levels were reduced in HFG (−10%, p = 0.044) when compared to CG, and there was no significant difference between groups in relation to insulin, T3, T4, and TSH after 180 days. Conclusions: Maternal severe hyperglycemia during pregnancy and lactation resulted in a microsomal offspring. Maternal consumption of flaxseed reduces blood glucose levels in adult offspring without significant effects on insulin levels and thyroid hormones.
