Abstract

Changes in mesenteric lymph nodes from Fischer F344 rats ranging from 5 to 37 months were studied by histological and histometric techniques. The most drastic histological changes were observed between 12 and 37 months of age. These changes include: (1) loss of cellularity in the cortex; (2) decrease in the number of germinal centers; (3) distension of the medullary sinuses; (4) decrease in the ratio of cortical area to medullary area; and (5) infiltration of fibroblastic cells in the cortex and the medulla. Our results indicate a general structural disorganization in the mesenteric lymph node with increasing age. Such structural disturbance might be an important extrinsic factor for the decline in lymphocyte functions.
