Avian Pancreatic Polypeptide

The distribution of nerve fibers in the middle ear mucosa and eardrum of the cat and guinea pig was studied using immunocytochemical and histofluorescence techniques. Nerve fibers containing noradrenaline, vasoactive intestinal peptide, substance P, enkephalin or immunoreactive avian pancreatic polypeptide were demonstrated in the middle ear mucosa. After extirpation of the superior cervical ganglion, nerve fibers containing noradrenaline and avian pancreatic polypeptide disappeared while fibers containing vasoactive intestinal peptide, substance P and enkephalin seemed to remain unaffected.

And Control

The majority of blood vessels in the superior cervical ganglion possess a continuous endothelium with tight junctions. These same features have been associated with the blood brain barrier of the central nervous system and peripheral nerves. These vessels may perform a barrier function between the capillary circulation and the superior cervical ganglion. The permeability of the blood vessels in the superior cervical ganglion of the rat was tested by intravenous injection of horseradish peroxidase (HRP). Three experimental groups of four animals each were given intravenous HRP (Sigma Type II) in a dosage of.08 to.15 mg/gm body weight in.5 ml of.85% saline. The animals were sacrificed at five, ten or 15 minutes following administration of the tracer. Superior cervical ganglia were quickly removed and fixed by immersion in 2.5% glutaraldehyde in Sorenson's.1M phosphate buffer, pH 7.4. Three control animals received,5ml of saline without HRP. These were sacrificed on the same time schedule. Tissues from experimental and control animals were reacted for peroxidase activity and then processed for routine transmission electron microscopy.
