Injection into the hind footpad of the rat combines intradermal and subcutaneous routes. Material injected into the dermis of the sole is rapidly distributed by the lymphatics to several lymph node groups and enters the bloodstream principally with the thoracic duct lymph. The diffuse character of the lymphatic drainage of this site is emphasized. Material in the subcutaneous tissues gradually enters the systemic circulation and is filtered through various organs. Antigen injected into the footpad can elicit both effective delayed hypersensitivity and humoral host responses.
将物质注射到大鼠后足垫结合了皮内和皮下途径。注入足底真皮的物质会通过淋巴管迅速分布到几个淋巴结群,并主要随胸导管淋巴进入血液循环。强调了该部位淋巴引流的弥散性。皮下组织中的物质逐渐进入体循环并通过各种器官进行过滤。注入足垫的抗原可引发有效的迟发型超敏反应和体液宿主反应。
