In the past few years, a large family of adhesion molecules has been defined which are receptors for these adhesion events. Using immunohistochemical techniques we analyzed the distribution pattern of adhesion molecules in the buccal mucosa of 12 patients with oral lichen planus reticularis and compared it with 12 specimens of normal oral mucosa. In lichen planus, a neo-expression of the antigens VLA-1, 3, 5 and 6, which are receptors for collagen, fibronectin and laminin, could be detected on T cells and macrophages infiltrating the basement membrane zone. ICAM-1, the specific ligand of LFA-1, normally only expressed by endothelial cells, showed a focal expression on basal keratinocytes at sites of intramucosal T cells. The abundance of adhesion molecules on leukocytes and keratinocytes in oral lichen planus is indicative of a special state of activation. It enables the leukocytes to penetrate the tissue, especially the basement membrane zone, to persist in this environment and to exercise their effector functions.</p>","PeriodicalId":77522,"journal":{"name":"Deutsche Zeitschrift fur Mund-, Kiefer- und Gesichts-Chirurgie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1991-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12976405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The minor salivary glands are shown to be organs whose function is decisively involved in symptoms such as xerostomia, stomatodynia, and what is known as \"denture intolerance\". Moreover, proper secretion of the palatine glands is of crucial importance for the physical retention of maxillary full dentures. There are no connections between secretory rates of major and minor salivary glands. The effect of certain drugs on salivary production and thus on the symptoms of hyposalivation seems to be considerable. Treatment methods for inadequate salivary secretion are outlined. The adaptive tendency of properly functioning palatine glands appears to be high. The fact that atrophic and dystrophic processes can be functionally compensated to a relatively high degree speaks for the dynamic capability of the glandular parenchyma. In view of the clinical relevance of the minor salivary glands it is mandatory that the functional principles and control mechanisms underlying their secretion be investigated in future studies.</p>","PeriodicalId":77522,"journal":{"name":"Deutsche Zeitschrift fur Mund-, Kiefer- und Gesichts-Chirurgie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1991-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12978064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The osteoblasts were multiplied in cell cultures and after 3 passages inserted along with granular HA into monocortical femur defects in 24 rats of the same inbred line.
