Background: Using chemical agents in the treatment of diabetes mellitus type 2 may have some limitations due to frequent side effects. Some novel and natural agents may be promising alternatives in this case. This study was designed to evaluate the effects of oral Japanese sake yeast supplement, as a novel agent, on biochemical antioxidant and anti-inflammatory parameters in experimentally induced diabetic rats.
Materials and methods: After inducing diabetes (55 mg/kg intraperitoneal injection of streptozotocin), 120 male adult Wistar rats were randomly divided into 5 groups and each group received 0 (control), 15, 30, or 45 mg/kg of sake yeast or was considered a nondiabetic control. Then, the serum levels of tumor necrosis factor-α, IL-6, C-reactive protein, malondialdehyde, glutathione, total antioxidant status, glucose, cholesterol, triglycerides, and insulin were evaluated and compared to baseline measures.
Results: The results showed that oral administration of sake yeast at different concentrations reduced levels of malondialdehyde, glucose, cholesterol, and triglycerides and increased levels of insulin, glutathione, and total antioxidants (P<0.05). The best responses were observed in the nondiabetic control group.
Conclusion: Sake yeast supplement may be useful as a novel agent in the treatment of diabetes.
Keywords: sake yeast, diabetes, glucose, insulin, inflammatory factors, lipid profile, antioxidants
