to define further the developmental history of cholinergic sympathetic neurons , we have used immunocytochemical techniques to examine developing and mature sweat gland innervation for the presence of the catecholamine synthetic enzymes tyrosine hydroxylase ( th ) and dopamine beta-hydroxylase ( dbh ) and for two neuropeptides present in the mature cholinergic innervation , vasoactive intestinal peptide ( vip ) and calcitonin gene-related peptide ( cgrp ) .
