    Description / Table of Contents: Summary An electron microscopic study of the submandibular salivary gland lesion occurring in the NZB/NZW F1 hybrid mice was performed, and the findings were discussed and correlated to the autoimmune salivary gland disease observed in patients with Sjögren's syndrome. Within the submandibular salivary gland of this mouse strain focal infiltrates of mononuclear inflammatory cells were observed. Lymphoid cells were observed inside the basal lamina of acini and ducts, leading to destruction of these glandular units. The typical duct cell proliferation found in the autoimmune sialoadenitis of Sjögren's syndrome with the formation of the typical epimyoepithelial islands was not found in the submandibular glands of NZB/NZW mice.
    Notes: Zusammenfassung Eine elektronenmikroskopische Untersuchung der bei den NZB/NZW F1 hybriden Mäusen vorkommenden Veränderungen in den submandibularen Speicheldrüsen wurde durchgeführt, und die Befunde wurden diskutiert und korreliert mit dem autoimmunen Speicheldrüsenleiden, das bei Patienten mit Sjögrens-Syndrom beobachtet wird. In der submandibularen Speicheldrüse dieses Mäusestammes wurden begrenzte Infiltrationen mononuklearer inflammatorischer Zellen beobachtet. Die mononuklearen Zellen wurden hauptsächlich als lymphoide Zellen identifiziert. Außerdem wurden innerhalb der Lamina basilaris von Drüsen und Drüsengängen lymphoide Zellen beobachtet, die zur Zerstörung dieser Drüseneinheiten führen. Darüber hinaus wurde der typische Zuwachs der Drüsengangszellen, der bei der autoimmunen Speicheldrüsenentzündung des Sjögrens-Syndroms vorkommt und die Form von typischen epimyoepithelialen Inseln annimmt, in den submandibularen Drüsen der NZB/NZW-Mäuse nicht vorgefunden.

    Notes: Summary Immunohistochemistry was used to study the localization of lysozyme (LZ) and lactoferrin (LF) in the human sinus mucosa during recurrent and chronic sinusitis. Serous cells of submucosal mixed glands and polymorphonuclear leukocytes both displayed a strongly positive staining reaction to both LZ and LF in the normal mucosa. A positive though weak staining for LZ and LF could also be found occasionally within goblet cells. In the mucosa from patients with recurrent or chronic sinusitis, the staining reaction to LZ appeared to intensify in goblet cells. Furthermore, an increased immunoreactivity of glands vis-à-vis LZ and LF was also noted occasionally. Atypical glands were frequently found in mucosa from patients with chronic sinusitis. The epithelium of these latter glands often showed an intense staining reaction to LF, but a rather weak reaction to LZ. The results of the present study suggest that the observed increase in LZ and LF secreting activity of goblet cells, epithelial cells and newly formed atypical glands may play a part in the defense mechanism of the sinus mucosa during the course of chronic sinusitis.
