RESUMO
The current study was performed to study the effect of biologically synthesised gold nanoparticles (AuNPs) to control hyperglycaemic conditions in streptozotocin (STZ)-induced diabetic mice. In this study, the rats were divided into four groups: Group I normal control rats (non-diabetic, untreated); Group II diabetes-induced rats used as diabetic controls DC (diabetic, untreated). Group III diabetes-induced rats treated with AuNPs DT; Group IV normal rats treated with AuNPs NT. Diabetes was induced by administering an intraperitoneal injection of a freshly prepared solution of STZ (50mg/kg body weight (bw)). The glucose level was significantly increased in the diabetic control rats compared with the controls (P<0.001). Decreased liver function and kidney function were detected in the diabetic treated rats and normal treated rats after AuNP administration compared with the controls. The present study is the first to demonstrate that AuNPs significantly enhance antioxidant production in STZ-induced diabetic rats, a recognised model of type 1 diabetes mellitus (T1DM).
