Duzguner, V., Kucukgul, A., Erdogan, S., Celik, S. and Sahin, K. 2008. Effect of lycopene administration on plasma glucose, oxidative stress and body weight in streptozotocin diabetic rats. J. Appl. Anim. Res., 33: 17–20. To evaluate the role of lycopene, a carotenoid antioxidant, on streptozotocin (STZ)-induced diabetic rats, 12 female rats received a single intraperitonial injection of STZ at a dose of 45 mg/kg body weight of which 6 were given 10 mg/kg lycopene orally (test group) once daily for 21 days. The administration of STZ caused a significant increase in plasma glucose and decrease in body weight. The supplementation of lycopene significantly reduced diabetic plasma glucose level by 25% and prevented body weight loss starting from 14th day of lycopene administration. Although tissue lipid peroxidation and nitric oxide (NO) levels were unchanged, lycopene administration significantly reduced diabetes-elevated lipid peroxidation and NO in plasma. It was concluded that lycopene supplementation may be valuable for correcting hyperglycemia and preventing diabetic complications caused by lipid peroxidation and free radicals. © 2008 Taylor & Francis Group, LLC.
