Background and Aim: Aloe vera (Aloe barbadensis) and Teucrium (Teucrium polium) are used in traditional medicine as anti-diabetic herbs. The present study examined the effects of TP and aloe vera extracts on some metabolites like glucose, total cholesterol, LDL, HDL, VLDL and triglycerides in streptozotocin-induced diabetic Wistar rats. Materials and Methods: In this experimental research, forty rats were randomly divided into five equal groups. Trials in the study included the control group, diabetics (50 mg/kg STZ), diabetics+extract of Aloe vera (300mg/kg), diabetics+Teucrium (300mg/kg), and diabetics+glibenclamide (5mg/kg). All solutions were given orally for 14 days. Blood samples of the rats were derived from their hearts on the 15th day of the experiment and their serum was isolated. Results: Blood glucose in diabetic rats significantly reduced by aloe vera and Teucrium extracts (P≤0.05). It was found that concentration of total cholesterol, HDL, VLDL and triglycerides in rats receiving Aloe vera and Teucrium extracts and glibenclamide was significantly lower than diabetic rats (P≤0.05). Aloe vera and Teucrium were more effective than glibenclamide in reducing blood cholesterol levels. Compared with Aloe vera and glibenclamidettreatment with Teucrium had less effect on serum triglycerides. Serum insulin levels in diabetic animals receiving the herbs extracts significantly increased in comparison with diabetic rats. Conclusion: The use of Aloe vera and Teucrium extracts improve insulin secretion and reduce blood glucose and LDL

Background and Aim: Diabetes is one of the mortality factors in the world. Nutritional and environmental pollution with heavy metals, especially lead, exacerbates diabetic condition. The curcumin in Turmeric has antioxidant properties and therapeutic effects on the treatment of some diseases such as diabetes. Materials and Methods: In an interventional experiment designed to investigate the protective effect of turmeric powder on consequences of lead acetate on some blood parameters in the diabetic male rats, 32 male Wistar rats with an average initial weight of 182.6±1.8 g each were randomly divided into four groups, i.e. the control, diabetic (streptozotocin injection in dose of 55 ppm), diabetic+Pb (100 ppm solute in water), and diabetic+Pb+CL (2% of DMI). Trial period was 4 weeks. Blood samples from the heart of the rats were taken on the 29th day. Results: Turmeric powder improved insulin secretion and reduced blood glucose. Total protein increased in CL treatment group. ALT, AST, triglyceride, and cholesterol significantly increased in diabetes treatment groups compared with the control. Conclusion: Probably the antioxidant compounds found in Turmeric especially curcumin can reduce some complications of lead acetate in diabetic patients.
