| Abstract: | The technique of radiographic examination by lymphography of normal lymphatic structures regional to the hind limbs is described in the rabbit, dog and rhesus monkey. Radiographic appearances of normal lymph nodes and possible applications to veterinary science are indicated. Normal lymph node microstructure is illustrated using in vivo intralymphatic injection of a brightly colored radiopaque silicone rubber. Angiogenesis in active germinal follicles during the period of an immune response is displayed. Further applications of the casting technique are suggested. |
