The Therapeutic Efficacy of Ultrasound in Treatment of Autoimmune Diseases
The elimination of circulating lymphocytes by thoracic duct (TD) cannulation and drainage has shown to be a effective treatment for some patients suffering the debilitating effects of autoimmune diseases.1–5 it was desirable to eliminate the thoracic duct cannulation procedure and its associated lengthy hospitalization. Therefore, we undertook an experimental investigation of the feasibility of using an ultrasonic transducer for the destruction of TD lymphocytes in vivo. In addition we investigated potential hazards to the patient associated with this method of lymphocyte destruction. Finally, we made some measurements on the ultrasonic destruction of red blood cells and Hela cells in order to determine whether there were qualitative or quantitative differences among different cell types in their response to ultrasound. In this article we present data showing that it is feasible to destroy lymphocytes by ultrasonic irradiation (US) of the thoracic duct fluid and that it may be feasible to destroy lymphocytes by the ultrasonic irradiation of peripheral blood. In addition data is presented which show that red cells and Hela cells exhibit similar sensitivities to that shown for lymphocytes following ultrasonic irradiation.
