Lymphatics, Lymph and Lymphoid Tissue
In the introductory chapter of this book it is explained that in the lower vertebrates there are lymphatic vessels but no lymph nodes; the lymphoid tissue in fish and amphibia is associated with myeloid tissue in such organs as the intestines, kidney, and liver. Lymph nodes first appear in certain birds, but it is only in mammals that they are invariably present. However, even in mammals, where...
متن کاملRadiographic demonstration of intercostal lymphatics and lymph nodes.
The anatomy of the posterior intercostal lymphatics and lymph nodes is reviewed. These lymph nodes are occasionally visualized by bipedal conventional lymphography. Opacified and/or enlarged posterior intercostal lymph nodes may also be identified with computed tomography of the chest. Familiarity with the lymphatic drainage patterns of the intercostal spaces and recognition of abnormal interco...
متن کاملIntratumoral lymphatics and lymph node metastases in papillary thyroid carcinoma.
OBJECTIVE To examine the relationship between lymphatic vessel density and clinical and pathological variables in patients with well-differentiated papillary thyroid carcinoma. SUBJECTS Clinical information was retrieved on 109 previously untreated patients with well-differentiated papillary thyroid carcinoma treated with total thyroidectomy and postoperative iodine I 131 ablation. Median fol...
متن کاملRecent advance in lymph dynamic analysis in lymphatics and lymph nodes.
Lymphatics are a unidirectional transport system that carries fluid from the interstitial space and back into the blood stream. Initial lymphatics take up not only fluid but also high-molecular-weight substances, such as plasma proteins and hyaluronan; immune cells, such as lymphocytes, macrophages, and dendritic cells; and colloidal particles, such as carbon particles, bacteria, and tattoo dye...
متن کاملQuantitative analyses of lymphoid tissue in the spleen, lymph nodes and Peyer's patches in cynomolgus monkeys.
To clarify the morphological characteristics of the cynomolgus monkey immune system, we analyzed quantitative data on their lymphoid organs. Spleens, major lymph nodes and Peyer's patches were sampled from cynomolgus monkeys, and the lymphoid follicle and germinal center areas and percentages of CD3- and CD20-positive areas were calculated. All the organs analyzed showed large interindividual v...
