Morphology of the abdominal hemolymph nodes in the Wistar rats.

In 26 Wistar rats the morphology of 30 renal and 20 splenic lymph nodes were investigated. The left renal nodes are usually singular as compared to multiple right renal nodes. Microscopically they present segmental structure with erythroidal elements located mainly in the medullary cords. The splenic nodes, 1 to 5 in number do not show segmental structure but have uniformly dispersed erythroidal elements.
