Abstract
Drainage of lymph from the thoracic duct as part of the immunosuppressive treatment in human, homologous kidney transplantation has been tried in 18 cases. A reduction of the concentration of lymphocytes in the lymph during the drainage could be shown. The procedure was not accompanied by a reduction of the number of lymphocytes in the peripheral blood. The rejection episodes were less frequent when none or very low lymph volumes and also large lymph volumes were collected.
