Intestinal Polypeptide

Vasoactive intestinal polypeptide (VIP)– and substance P–containing nerve fibers were observed in the cerebral blood vessels using an immunohistochemical technique. VIP-containing nerve fibers distributed in a spiral pattern, similar to that of muscle cells. Under electron microscopic observation, VIP-immunoreactive terminals lay close to a muscle cell in the inner layer of the adventitia. In contrast, substance P–containing nerve fibers showed a meshwork pattern in the outer layer of the adventitia. Using both acetylcholinesterase (AChE) staining and VIP immunohistochemistry, AChE-positive and VIP-immunoreactive nerve fibers revealed almost the same distribution in the same specimen. The present data suggest that VIP-containing nerve fibers may play a role in the smooth muscle control of the blood vessels, whereas substance P–containing nerve fibers may not take part in muscle control.

Intestinal Polypeptide

The distribution of adrenergic, cholinergic and peptidergic nerves in the feline eustachian tube was studied using histochemical techniques. Adrenergic, acetylcholinesterase-positive and vasoactive intestinal polypeptide immunoreactive nerves were numerous in the tubal wall. All three types of nerve fibers occurred in the subepithelial layer, around small blood vessels and around the acini of seromucous glands. No nerves displaying substance P or enkephalin immunoreactivity were observed.
