Acinar cells, which are seromucous in nature, contain secretory granules that often contain a perfect \u201cbull's eye\u201d inclusion (or some variant of this configuration) suspended in a dense matrix. The Golgi apparatus in these cells has an unusual structure, with the Golgi saccules often being doubled over, so that the outermost saccule also is the innermost. This peculiar architecture apparently arises fairly late in the secretory process, i.e., a Golgi apparatus of conventional structure gives rise to a nascent granule (condensing vacuole), then its saccules secondarily fold over. Intercalated ducts are preceded by a ring of specialized cells that have a number of serous\u2010type granules, the duct cells themselves being devoid of such granules. Granular convoluted tubules (GCT) contain large dense granules that appear to be spontaneously involved in chain exocytosis. These GCT granules probably are the repositories of nerve growth factor, which is particularly abundant in <jats:italic>Praomys<\/jats:italic>. Striated ducts for the most part are typical in appearance, but they and, to a lesser extent, GCTs contain prominent, membrane\u2010bound crystalloids with a periodicity of about 15 nm.<\/jats:p>","DOI":"10.1002\/ar.1092290208","type":"journal-article","created":{"date-parts":[[2005,2,26]],"date-time":"2005-02-26T20:55:22Z","timestamp":1109451322000},"page":"209-218","source":"Crossref","is-referenced-by-count":5,"title":["Ultrastructure of the submandibular gland in the African multimammate rodent, <i>Praomys natalensis<\/i>"],"prefix":"10.1002","volume":"229","author":[{"given":"Kuniaki","family":"Toyoshima","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernard","family":"Tandler","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,1,26]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0014-4827(81)90345-1"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1679\/aohc1950.38.177"},{"key":"e_1_2_1_4_1","first-page":"257","article-title":"Fine struttura ed aspetti stagionali della ghiandola parotide","volume":"91","author":"Azzali G.","year":"1986","journal-title":"Arch.
