This study aims to research the effect of streptozotocin (STZ) at different doses on the serum micronutrients and oxidative stress status in diabetic rat models. Twenty male rats averaged 250 g and 3-4 months old were used as experimental models. They were put in four groups composed of five rats each. Diabetic was induced by administering STZ 55 and 65 mg/kg intraperitonally. The serum micronutrients including minerals and vitamins (Cu, Zn, Mg, Fe, vitamins D, E, and C) and oxidative stress (malondialdehyde, MDA) were determined. Cu, Zn, and Vitamin D3 levels were found to increase significantly in STZ groups (p < 0.005). Retinol levels decreased significantly in STZ groups (p < 0.005). In the groups administered 55 mg/kg STZ ferrum and vitamin C levels were found significantly lower than the other groups (p < 0.005). In the group given 65 mg/kg STZ a-tocopherol levels were highest (p < 0.005) among other groups. There was not any difference between the groups for MDA, Cu/Zn, and Mg. For both doses, oxidative stress status was not significantly affected within 48 h of the application, however, some micronutritents were affected significantly.
