Material/Methods: In 12 Wistar rats the gross and microscopic structure of haemolymph splenic nodes was assessed after splenectomy and the obtained results were compared with those in the control group.
Results: It was found that splenectomy leads to generalised morphological changes of the mentioned nodes, including, among other, their blanching, enlargement, filling with a greater number of morphotic elements and decreased count of erythrocytes and products of their disintegration. The splenic nodes demonstrated no regressive changes, typical of uniorgan nodes. The remaining abdominal non-haemolymph nodes in the rats showed no compensatory changes on gross examination after splenectomy.
