Animal-experimental and clinical results after applications of viscous solution with Fluorescein-Sodium and Erythrosin for representation of lympho-nodes and lymphatic ducts were published. In the frame of lymphography this application in form of a second infusion becomes possible preoperatively as well as intraoperatively. The lymphonodi inguinale, iliaci and lumbales represented even by lymphography were contrasty stained by this method over limited period.
