[Immunohistochemical study on the distribution and coexistence of SP, VIP and NPY in the rat submandibular gland].
The distribution and coexistence of SP, VIP and NPY in the submandibur gland of rat have been studied with immunohistochemical ABC methods. The results indicated that SP, VIP and NPY-IR nerve fibers were presented as varicose and linear profiles, which mainly travelled around acini, duct and blood vessels. The ganglion cells in submandibular gland showed SP, VIP and NPY-IR all positive immunocytochemically. The findings indicated that the neuropeptides were coexisted in the same neuron body and might play the role of regulation of the secretary activity and effective blood supply.
