Diabetes was induced using streptozotocin (65 mg/kg), and treatments were administered over four weeks. Serum markers for renal and hepatic function, oxidative stress indices, and histopathological changes in liver and kidney tissues were assessed.<br /> <strong>Results:</strong> In diabetic rats, serum urea, creatinine, and liver enzymes (ALT, AST, ALP, LDH, GGT) increased significantly (p<0.05), while treatment with PRP, EPO, or both significantly reduced ALT, AST, ALP, LDH, and GGT (except in the combined group for GGT; p>0.05). Renal and hepatic SOD decreased significantly in diabetes (p<0.05) but improved with treatment, especially in the combined group (p<0.05). Renal TAC increased in diabetes and decreased significantly after treatment (p<0.05). No significant changes were observed in GPX or MDA levels (p>0.05). Damage in kidney and liver tissues were obtained in diabetic group. Histopathological improvements were evident, in hepatocyte integrity and glomerular structure, with EPO and PRP treatments.<br /> <strong>Conclusion: </strong>The results emphasize the potential of EPO and PRP as complementary therapeutic strategies to reduce diabetes-induced oxidative damage and structural deterioration in liver and kidney tissues. However, further adjunctive approaches are required to achieve comprehensive organ protection.</span></span></p> Platelet-rich plasma, Erythropoietin, Diabetes, Kidney, Liver 70 80 http://ppj.phypha.ir/browse.php?a_code=A-10-2538-1&slc_lang=en&sid=1 Seyedeh Bahar Ahooghalandari ahooghalandarib@gmail.com 3200319475328460039448 3200319475328460039448 No Department of Clinical sciences, Faculty of Veterinary medicine, Shahid Chamran University of Ahvaz, Ahvaz, Iran Seyedeh Missagh Jalali mi.jalali@scu.ac.ir 3200319475328460039449 0000000301885974 Yes 1.
