title: [Experimental study on the lymphatic and cerebrocervical drainage and changes therein caused by ultrasound (author's transl)].
abstract: After indian ink or ferritin are introduced into the cerebral hemispheres or subdural space these substances can be found in the deep cervical lymph nodes. The transport of these substances can be enhanced and accelerated by the treatment of deep cervical lymph nodes by ultrasound. Treatment of the paravertebral region with ultrasound after the introduction of ferritin or indian ink subdurally is followed by the appearance of these substances in the suprarenal gland, the testis, epididymis and the prostate gland where they are conveyed by the lymphatic pathways. Thirty minutes after the injection of ferritin into an afferent lymphatic channel of a deep cervical lymphatic node pretreated with ultrasound, ferritin can be found in the pia and arachnoid membranes of the cerebral hemispheres. Ultrasound treatment of the cervical lymph nodes not only seems to enhance the drainage of this substance from the brain but if the dose of ultrasound is high the direction of the lymphatic flow may be reversed.
