Abstract

Context: Gestational diabetes is defined as carbohydrate intolerance with onset or first recognition during pregnancy. Diabetes during pregnancy increases the incidences of congenital anomalies, in a mother and her embryo. Oxidative stress has been implicated to be responsible in diabetic embryopathy. Objective: In this study, we used nanoceria as an antioxidant for amelioration of diabetic embryopathy in diabetic mice. Methods: The female mice were divided into 5 groups (6 mice per group). Diabetes was induced by a single dose of streptozotocin (60 mg/kg IP) that dissolved in citrate buffer (pH= 4.6). Blood glucose was checked in 0,5,10, 15 days of pregnancy. The diabetic state was confirmed when the blood glucose concentration exceeded 200 mg/dl. On the Day 16 of pregnancy, all animals were anesthetized with ether and embryos were excised, then oxidative stress, pathological parameters, number of implantations, miscarriage and live embryo was assayed. Results: Histological study showed that diabetes induced abortion; decrease in weight of mothers, embryo and the number of embryos. In diabetic mice, significant increase in lipid peroxidation (LPO), ROS formation and protein carbonyl content were observed. Glutathione (GSH) concentration is found to be decreased in embryo tissue in diabetic mice. Nanoceria treatment significantly inhibited embryonic oxidative stress and also pathologic changes in diabetic mice. Conclusions: Our research showed that diabetes act as a teratogen agent for fetal development and nanoceria abrogated diabetes induced embryopathy via its antioxidant effects. So, early detection of diabetes in pregnancy and antioxidant administration can attenuate these complications.
