Background/aims: Gestational Diabetes Mellitus (GDM) is a common complication during pregnancy, defined as diabetes diagnosed in the second or third trimester, often asymptomatic. This study investigates the therapeutic potential of olive leaf extracts and stem cells in mitigating GDM-induced complications, particularly focusing on renal function, oxidative stress, and pancreatic cell regeneration.
Methods: Measurements were made in gravid female rats with or without intraperitoneal administration of Streptozotocin (35 mg/kg body weight). Biochemical analyses were conducted to evaluate renal function markers (urea, uric acid, creatinine) and oxidative stress parameters (malondialdehyde, glutathione, and superoxide dismutase levels). Histopathological and immunohistopathological evaluations of kidney tissues were performed using hematoxylin and eosin staining and specific markers (p53, Insulin, and PCNA) to assess cellular changes.
Results: The diabetic group exhibited significantly elevated levels of urea, uric acid, and creatinine (p<0.01) compared to the control group. Treatment with stem cells and olive leaf extracts significantly reduced these levels. Malondialdehyde levels were elevated in the diabetic group (p<0.01) but showed marked improvement in the treatment groups. Additionally, glutathione and superoxide dismutase activities were diminished in the diabetic rats (p<0.05) but increased following treatment. Histopathological and immunohistopathological analyses revealed cellular regeneration and improved tissue morphology in the treatment groups compared to the diabetic group.
Conclusion: Stem cells and olive leaf extracts exhibit significant therapeutic potential in ameliorating renal dysfunction, oxidative stress, and tissue damage associated with GDM, highlighting their role in enhancing pancreatic cell regeneration.
