Previously we reported an experimental electro-physiologic study of ulnar neuritis to decide the cause, the indication of operative treatment and the chance for operation. In addition to the investigation, lesions resembling ulnar neuritis seen in the nerve compression syndromes were induced in rabbits, and the vascularity of this experimental lesions was examined angiographically.Material; normal and gently compressed confricted sciatic nerves with Vinyl-tube of mature rabbits.Method; This research was studied in detail by injecting a micro-suspension of barium sulphate into the rabbits' aortae of various levels and then displaying the injected vessels by microradiography of the nerve.Consequently, the slight angiographic findings were obtained by injecting the rabbits' arcus aortae of which aorta thoracica had been ligated. This fact suggests that the axonal vessels are the other important factor to the nutrition of rabbits' sciatic nerves and the early operation for the ulnar neuritis may be recommended.
