IMPLANTATION OF GREAT AURICULAR NERVE IN SUBMANDIBULAR SALIVARY-GLANDOF DIFFERENT-AGED RATS

The were conducted experiments dealing with implantation of proximal s egment of great auricular nerve in submandibular salivary gland of whi te rats at the different ages: young (1-month-old);, puberal (6-month- old) and aged (18-20-month-old), denervation being performed by disloc ation of the gland from its connective capsule; reinnervation reaches homoimplantations of great auricular nerve in tissue of partially dene rvated gland. Implantation of the above nerve was revealed to result, at first, in time limitation of an oppression process of the gland ner ve apparatus function and then in its restoring. In young rats the opp ression proces of the nettron function terminates in a month. In aged animals it is appreciably protracted: normalization, can be observed w ithin 4 months after the operation. Implantation of somatic nerve in p artially denervated submandibular salivary vary gland ensures recovery of its intraorgan nerve apparatus. Recovery rates approximately equal in young and puberal animals and are considerably delayed in old indi vidual.
