Abstract

Limb allotransplantation is not a life-saving treatment. However, large doses of immunosuppressive agents are needed. There is an urgent need to increase the selectivity and targeting of drugs. We designed a rat model for intraarterial infusion of cyclosporine (CSA) based on the hindlimb replanted model to simulate the limb allotransplantation. To investigate whether intraartery infusion could improve the drug's distribution, we infused CSA 4.0 mg/kg per day continuously into either the superficial epigastric artery (IA group) or superficial epigastric vein (IV group) of Lewis rats. On day 10, CSA concentrations were measured in skin, muscle, and bone tissues of hindlimb. Samples were taken from different parts of the bilateral hindlimbs in the IA group and right hindlimb only in the IV group. Tissue concentrations of the perfusion side were much higher in IA group. Systemic concentrations of IA group were higher than IV group. These results warrant further research in our next limb allotransplantation model.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
