Two hours after Alcian Blue (AB) dye was injected at the rat acupoint BL23, the abdominal cavity was examined and AB-stained threadlike structures were observed on the right abdominal cavity. Those threadlike structures were mainly distributed on the surfaces of the duodenum, colon and cecum. These threadlike structures were thin (about 50 microm) and moved freely, and were connected to corpuscles that were about 500 x 200 microm wide and also stained with AB. On analyzing the histology of the threadlike structures, rod-shaped nuclei, bundles of collagen fibers, reticulofibers, and squamous-like epithelial cells were observed. Immune cells and some sinuses were inside the threadlike structures. These characteristics describe those of Bonghan ducts. The flow paths from the acupoint to internal organs can possibly be used as paths for drug delivery.
在大鼠穴位BL23注射阿尔新蓝（AB）染料两小时后，检查腹腔，在右腹腔观察到AB染色的丝状结构。这些丝状结构主要分布在十二指肠、结肠和盲肠表面。这些丝状结构很细（约50微米），能自由移动，并与宽约500×200微米且也被AB染色的小体相连。对丝状结构进行组织学分析时，观察到杆状细胞核、胶原纤维束、网状纤维和鳞状上皮样细胞。丝状结构内部有免疫细胞和一些窦。这些特征描述的是凤汉管的特征。从穴位到内脏的流动路径可能可用作药物输送的路径。
