the immunohistochemical data as well as the enrichment of extractable enkephalins in islets compared with whole pancreas indicate that essentially all the met-enkephalin present in pancreas is localized in islets , while the presence of bam-22p immunoreactivity in islets is consistent with biosynthesis of enkephalins in islet cells via a preprohormone , such as that described in the bovine adrenal medulla and rat brain .
