    Abstract:
    Histochemical, immunohistochemical and histomorphometrical changes in sialadenitis have been studied on 33 biopsies of labial salivary glands (LSG) from patients with primary Sjogren's syndrome. The control group consisted of 10 biopsies from persons without oral cavity inflammatory diseases. A direct relation was established between xerostomia stage and the degree of LSG parenchyma substitution for the inflammatory cell infiltrate. Dependence of LSG tissue damage on local immunopathologic reaction was detected. With a highly active inflammatory reaction the changes were characterized by cellular hypersensitivity including inflammatory cell infiltrate (T-lymphocytes, macrophages, neutrophils), increased vascular permeability, destructive and proliferative changes of the intralobular ductuli and acini. Reduction in inflammatory activity was accompanied by a decrease in the number of macrophages and neutrophils, an increase in the number of plasma cells and mast cells, higher compensatory hypertrophy of the serous cells of semicircular mixed acini, secretion products status, as well as intralobular sclerosis and lipomatosis.
