Pancreastatin: molecular and immunocytochemical characterization of a novel peptide in porcine and human tissues.

abstract：:Immunoreactive neurophysin (Np) is demonstrated by the immunoperoxidase technique not only within neurones of the classical hypothalamo-neurohypophyseal system, but also in extrahypothalamic perikarya and fibers. Np-positive perikarya are found in the triangular nucleus of the septum. Np fibers join the stria terminal...
