Abstract

Some new data on reinnervation of organs and vessels by means of transplantation of vegetative ganglia and sewing of neural branches are presented. When transplanting the cranial cervical ganglion to a muscle, and the caudal mesenteric ganglion to the urinary bladder wall, some neurocytes in the periphery of the ganglia are preserved; simultaneously, massive outgrowth of neural fibres occurs in the area of transplantation. These facts are considered as formation of a new local innervation center of the organ "recipient". The central part of the dog hypogastric nerve is sewed to the renal artery, in other experiments it is sewed into the rectum wall. A massive regeration of neural fibres along the course of the renal artery and the appearance of a neural ganglion in the rectum wall are stated. The sewed hypogastric nerve grows thicker, especially under the conditions of increased functioning of the organ "recipient". In a number of experiments, the large otic nerve is sewed to the common carotid artery. The development of a young connective tissue growing into the adventitia of the vessel is noted. Numerous regenerating neural fibres surrounding the vessel are noted in this tissue. Thus, a possibility of creating new or supplementary innervating connections of internal organs and vessels by means of sewing to them sensitive nerves or vegetative ganglia is morphologically substantiated.
