  • Abstract
  • Look Inside

By an immunohistochemical technique, vasoactive polypeptide (VIP)-and substance P-containing nerve fibers are observed in the cerebral bloodvessels. VIP-containing nerve fibers distribute in a spiral pattern, similar to the muscle cell distri-bution pattern. Under an electron microscopic observation, VIP-immunoreactive terminals lie just near to a muscle cell in the inner layer of the adventitia. In contrast, substance P-containing nerve fibers show a meshwork pattern in the outer layer of the adventitia. In combination of acetyl-cholinesterase (AChE) staining and VIP immu-nohistochemistry, AChE-positive and VIP-immu-noreactive nerve fibers reveal almost same dis-tribution in the same specimen. The present data suggest that VIP-containing nerve fibers may play a role of smooth muscle control of the blood vessels, while substance P-containing nerve fibers may not take part in muscle control.
