    Notes: Summary Motilin was demonstrated by the immunoperoxidase technique in endocrine cells of the gastrointestinal tract using several specific antisera. Motilin-like immunoreactivity could only be demonstrated with one of these antisera and was observed in Purkinje cells and dendrites of the cerebellum, in pyramidal cells and dendrites of the cerebral cortex and in dendrites of the CA3 field of the hippocampus of the rat. Very low motilin-like immunoreactivity was found in cerebellum as well as in cerebral cortex using radioimmunoassay. However, using reverse phase liquid chromatography combined with UV-detection and radioimmunoassay, no peak of a peptide corresponding to synthetic motilin was detectable in rat cerebellar extracts, in contrast to findings in rat duodenum. The results do not suggest that motilin is an intrinsic neuroactive substance of the cerebellum.

    Description / Table of Contents: Summary Benign fibroepithelial polyps of the renal pelvis are rare. Because of suspected malignancy in imaging procedures an ureteronephrectomy was carried out in the reported case. Histology, however, yielded no evidence of malignancy. The diagnosis of benign fibroepithelial polyp was entertained. It remains an open question whether the pathologic changes represent a hamartoma or a reactive postinflammatory process, revealing primitive myxoid stroma within the polypous portion and increasing fibrosis with diffuse submucosal involvement of the ureteral basis.
    Notes: Zusammenfassung Benigne fibroepitheliale Polypen des Nierenbeckens sind äußerst selten. Wegen des Malignitätsverdachtes in den bildgebenden Verfahren wurde im vorliegenden Fall eine Ureternephrektomie durchgeführt. Die histologische Untersuchung ergab jedoch keinen Anhalt für Malignität. Bei den hier vorliegenden Befunden eines benignen fibroepithelialen Polypen des Nierenbeckens ergibt sich die Frage, ob eine Hamartie vorliegt oder ein reaktives postentzündliches Geschehen mit primitivem myxoidem Stroma im polypösen Bereich und zunehmender submuköser Fibrose der Polypenbasis im Ureter.
