RESUMO
Diabetes and smoking have been considered as major health problems individually and their seriousness related to health hazard has been well reported. Data regarding the possible contribution of cigarette smoking to the development of diabetes are scarce and inconclusive. The aim was to investigate the effect of nicotine on diabetes and to analyze the effect of bis demethoxy curcumin analog (BDMCA) in streptozotocin (STZ) and nicotine-induced toxicity. The tissue lipids were extracted according to the method of Folch et al. Plasma and tissue cholesterol was estimated by the method of Allain et al. using reagent kit. Triglycerides were estimated by the method of Foster and Dunn. Free fatty acids were estimated by the method of Falholt et al. Tissue phospholipids were estimated by the method of Zilversmit and Davis. From our study, we found that nicotine not only aggravates diabetic complications but also increased the risk for diabetes. BDMCA, at a dose 80 mg/kg body weight was found to be effective in decreasing toxic effects induced by nicotine and STZ. Our data provide new evidence that cigarette smoking is an additional important factor that could be targeted for the prevention of diabetic complications.
