The current study purposed to evaluate the protective effect of Pinus gerardiana (PG) seed on oxidative stress induced by diabetes in the liver and serum of streptozotocin (STZ)-induced diabetic rats.Materials and Methods: This interventional study was performed on 36 male Wistar rats. The rats were randomly divided into 6 groups (healthy controls, healthy treated with 3% and 6% (PG), diabetic control, diabetic treated with 3% and 6% (PG) doses). After 6 weeks of intervention, weight, glucose, and oxidative stress parameters in serum and liver including total antioxidant capacity, malondialdehyde, total thiol and superoxide dismutase activity were measured. Data analysis was done by statistical software version 16 and Tukey’s one-way ANOVA tests.Results: Diabetic rats showed significantly higher malondialdehyde and fasting glucose levels (12± 1.2 mmol/L) and significant reductions in fasting insulin serum, weight (− 37%), and activity of superoxide dismutase enzymes, total thiol groups, and total antioxidant capacity of serum and liver (about +49% in liver and +16% in serum) (p < 0.001) compared with the healthy groups. Oral administration of PG nuts to diabetic rats caused a significant reduction in malondialdehyde and fasting glucose levels (− 43%) and weight loss (+15%), and a significant increase in activity of superoxide dismutase enzymes, total thiol groups, and total antioxidant capacity of serum and liver (p < 0.001).Conclusion: The present study concluded that PG can decrease fasting blood glucose, improve insulin resistance, reduce weight loss, and improve oxidative stress indices in the serum and liver of STZ-induced diabetic rats. It is a potential therapeutic food supplement for the treatment and prevention of hyperglycemia and high oxidative stress of diabetes.Keywords: diabetes mellitus, Pinus gerardiana, oxidative stress, blood glucose, rat |
