SUMMARY Aims Foot infections and the subsequent amputation of a lower extremity are most common cause hospitalization among patients with diabetes mellitus. Although there several reasons for susceptibility to infection in diabetic patients, white blood cell dysfunction is considered be an important this tendency. Granulocyte‐colony stimulating factor (G‐CSF) increases release neutrophils from bone marrow improves neutrophil functions. Based on knowledge, aim present study was investigate...
