Abstract:

Objective　To studythe Ag-NORs expressive character ofTlymphocyte in patientswith oral and maxillofacial tumor and evaluate its diagnostic value for the patients.Methods　Nucleolar organizer regions(NORs) of T lymphocyte from 86 normal adults, 102 patientswith oral and maxillofacial benign tumors and 87 patientswith oral and maxillofacial malignanttumorswere an- alyzed through KL imaging system.Results　There was significant difference among normal adults, benign and malignant patients (P<0·01). Their average I.S% valueswere 7·87±0·12, 5·72±0·14, 4·19±0·13, respectively.Conclusion　The expres- sion of Ag-NORs of T lymphocyte has definite relation with oral and maxillofacial tumors; detection of Ag-NORs might play valu- able in diagnosis of oral and maxillofacial tumors.

Key words: nucleolar organizer regions(NORs), T lymphocyte, oral and maxillofacial tumor
