Figure 1

Pathology of labial salivary gland from the participants. The degree of histopathological stage was graded from 0 to 4 according to Chisholm and Mason’s standards. Absent lymphocytes were observed in the LSGB at G0 from non-SS controls. In the LSGB of the pSS patients at early stage, slight or moderate infiltrate but less than one focus was observed, which was graded as G1 or G2. And the LSGB from the pSS patients at advanced stage showed one focus or more than one focus was graded as G3 or G4.
