We have analysed the hematological and immunological effects of the Furka's spleen chip method of autotransplantation in Balb/c mice two and eight months after splenectomy and autotransplantation. Our results showed that the autotransplants had positive effect on the partial restoration of the damaged elements of both cellular and humoral immunity appearing after splenectomy. However, these beneficial effects may have some dependence of time and species.
