The results indicated that the larynx as well as the trachea are containing the studied neuropeptides. The expression of these neuropeptides concerning histological structures were comparable to each other in both tissues. There was a strong immunoreactivity around seromucosal glands, blood vessels and within the epithelium but low concentrations within nerve fibers. The concentrations of the studied peptides by immunohistochemical methods increased in the following order: VIP < SP < CGRP < Bombesin. Some effects caused by these peptides like vasodilatation and hypersecretion seem to infuence the development of inflammations and allergical diseases. In healthy human trachea the neuropeptide bombesin could be detected for the first time. It could be found in a high concentration within the basal membrane of the epithelium. The fact that bombesin influences different growth factors might be an indication to its responsibility concerning the formation of scars or stenosis in tracheal tissue.
