ABSTRACT
A study was carried out on 40 dogs. Four groups of ten dogs each were established. A laparotomy group, a simple splenectomy group and two groups which underwent a selective autotransplant of the medium an deep layers of a centrifugated solution of splenic medulla respectively. Immunisation with BSA showed that humoral immune response with formation of anti-BSA antibodies is more intense in the control group which underwent laparotomy than in the splenectomised group. The response obtained in dogs subjected to autotransplant of deep layer is almost identical to that of the control group while that of the medium layer showed a slightly lower response. Cellular immune response is more accentuated in the group which underwent autotransplant from the deep layer, while those from the medium layer showed a higher response than that of the splenectomised group.

Primary and secondary humoral immune responses were studied in a group of 40 dogs after splenectomy and two types of splenic autotransplantation. The results enable the authors to conclude that splenectomy alone induces a depletion of immunoglobulins which is statistically significant. On the other hand, both types of autotransplantation made possible the maintenance of normal levels of anti-BSA antibodies. When autotransplantation was performed in the abdominal rectus muscle there was an enhancement of the primary immune response. The authors advise this procedure in all splenectomies for trauma in the first five years of life.
