    Comparison of the characteristic features of bonghan ducts, blood and lymphatic capillaries
    (Journal of Acupuncture and Meridian Studies, 2009-03-31) Ogay, Vyacheslav; Bae, Kyung Hee; Kim, Ki Woo; Soh, Kwang-sup
    Objective: To show that the characteristic morphological and ultrastructural features of a Bonghan corpuscle and duct presented here are consistent with the description given in the early reports of Bonghan Kim. Materials and Methods: We compared the morphological aspects of Bonghan ducts with those of blood and lymphatic capillaries on the ultrastructural level to display the manifestly distinctive nature of the Bonghan system. Results: The walls of the ductules were observed to be composed of a single layer of endothelial cells with characteristic rod-shaped nuclei and were not surrounded by a basal lamina or by accessory cells, such as pericytes or smooth muscle cells. The abluminal cell membranes of Bonghan ductules were not attached by anchoring filaments to the fibers of extracellular matrices as observed in lymphatic capillaries.
