title: Histological aspects of autologous transplantation of different fragments of the spleen in rats.
abstract: OBJECTIVE
  To evaluate macro and microscopically the evolution of autotransplants of fragments of spleen different fragments in the greater omentum, after eight weeks of observation.
  
  
  METHODS
  Twenty rats Wistar were used, males and adults, submitted to total splenectomy and divided in two groups. The group I - ten animals with implant of spleen fragment (25% weight of spleen) in the omentum; and group II - ten animals with implant of spleen fragment (30% weight of spleen) in the omentum. It was analyzed macro and microscopically the evolution of the implant.
  
  
  RESULTS
  It was observed adherences to the adjacent tissues and vascularization in all of the fragments transplanted. The group I and II presented white pulp with follicular formations and lymphoid tissue preserved, and the red pulp in cordon aspect. The group II presented white pulp more disorganized and red pulp hemorrhagic. The active macrophages were observed in the group I and II.
  
  
  CONCLUSIONS
  The splenic autotransplantation of the group I showed better regeneration.
