Present report concerns with the demonstration of regenerated nerve fibers on and around newforrned small vessels. Canalization vessels in an organized thrombus were used for this purpose. Experimental thrombus was formed by inserting a gelatine sponge in the common carotid artery (rabbits) and stained with Cajal's silver impregnation (modified). In two to three months after the insertion in an artery, the gelatine sponge becomes wholly organized and a recanalization through the thrombus by many small vessels takes place. Microscopical examinations of the thrombus in question disclosed that the nerves originally existing on the wall of the artery further proceeded into the thrombus already organized and fine nerve fibers were seen to regenerate. These fibers are running in the main parallel to the long axis of the mother artery and accompany recanalizing vessels. Although there is still much dispute in regard to the histologic structure of the nerves innervating capillaries, it is a problem of an immense interest whether the regenerated nerve fibers above mentioned would play a direct role in the innervation of recanalized small vessels. It may involve little doubt that the regenerated nerve fibers are the very elongation of the vasomotor nerves preexisting on the wall of the artery and therefore must be concerned with the vasomotor function of the new-formed vessel in the organized tissue. The author believes that along with a new-formation of blood vessels a regeneration of vasomotor nerves thereupon always concomitantly occurs.
