The effects of the PMN granule enzymes were additionally determined in the presence of an inflammatory exudate. These in vitro results indicated that as a result of these experimental conditions, the lysosomal enzymes, although present in relatively high concentration, were incapable of cell destruction and could only release cells from their growth surfaces; as could other proteases. However, even this effect was not expressed in the presence of naturally occurring inhibitors widely distributed in body fluids, such as serum; and most importantly which are also present in inflammatory exudates. This was in spite of the relatively high dilution of serum and inflammatory exudate used. So that, in effect, the relatively dilute inhibitors present in both serum and inflammatory exudates prevented the relatively concentrated lysosomal enzymes from exerting any discernible effects on either the cells, or the intercellular substance under these experimental conditions. This possibly suggests that the role of PMN granule enzymes as mediators of the cellular destruction observed in many inflammatory diseases, needs further elucidation.","PeriodicalId":16672,"journal":{"name":"Journal of oral pathology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1984-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/j.1600-0714.1984.tb01430.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17488827","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}

Parameters examined included flow rate, and concentration of sodium, potassium, chloride, urea, calcium, phosphate, total protein, IgA, IgG. albumin, amylase and lactoferrin. Although all SS patients had virtually no parotid secretion in the absence of stimulation, with a gustatory stimulation, 40% of the patients with SS had a relatively normal parotid flow rate, when compared with the control group. The SS patients, regardless of flow rate, exhibited a highly significant (p less than 0.01) elevation in the concentration of sodium, chloride, IgA, IgG, and lactoferrin and a significant (p less than 0.05) increase in albumin concentration, when compared with the control group. The phosphate level was significantly lower (p less than 0.01) in SS patients than in the control group. The elevated IgA in SS was almost all 11S, in contrast to parotitis where 7S was a major contributor. In view of the variation in flow rate in SS patients chemical quantitation of selected salivary components can be a valuable aid in the differential diagnosis of this disease and in monitoring patients over time.","PeriodicalId":16672,"journal":{"name":"Journal of oral pathology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1984-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/j.1600-0714.1984.tb01428.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17268583","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}

Following topical application of DMBA to cheek-pouches, lesions were classified as hyperplasia, dysplasia and carcinoma, with untreated pouches serving as a control. Stereological point counting procedures were used to determine the volume density of intercellular space in defined basal, spinous and granular layers for each group. In general, progressive increases in volume density were detected within each stratum during carcinogenesis. These results indicate that increasing separation of epithelial cells occurs during carcinogenesis, although it is not yet known whether this results from loss of cohesion between specialised (i.e., desmosomal) or nonspecialised membrane areas. In addition, a simple indicator of pathological alteration, the Pathological Alteration Ratio (PAR), is described and was used to evaluate existing published data for intercellular spaces in various oral mucosal conditions. Values of the PAR were found to be substantially higher in carcinogen-treated epithelia than in reports describing changes in wound healing, lichen planus and leukoplakia simplex. These objective techniques are of value for investigating the pathogenesis of diseased epithelium and may find applications in the diagnosis of oral premalignant lesions.","PeriodicalId":16672,"journal":{"name":"Journal of oral pathology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1984-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/j.1600-0714.1984.tb01422.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17488822","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}
