title: [Functional morphology of neural elements in interorganic adhesions and in coalesced organs].
abstract: The results of investigations concerning the problem on reinnervation of organs and vessels are summarized. Under the conditions of organo- and neuropexy, regenerating neural fibers pass through two stages of development. The first stage--formation and growth of neural fibers, the second--a more prolonged period of successive quantitative and qualitative morpho-functional transformations of these elements into mature structures. Judging from the histochemical characteristics, the latter become functionally competent by the 5th month after implantation of neural trunks into the arterial walls (the common, carotid and femoral arteries). The organopexies affect the neural cells structure in the denervated urinary organs. The reparative processes occurring, to some extent, protect them from destruction and stimulate their partial restoration. When the vegetative ganglia (the cranial cervical, caudal mesenteric ganglia) are transposed on the organs, some neurocytes are preserved. Their composition and histochemical structure correspond to an intact ganglion. A suggestion is made that the partly preserved ganglion could be used to form a new center of local regulation. An observation has been made according to which under the inductive effect of the donor-organ in the organ-recipient numerous newly formed neural fibers appear. They are capable to participate in reinnervation of the injured organ and, hence, in restoration of its function.
