ABSTRACT
A case of eosinophilic lymphoid granuloma(ELG)was reported and the related literatures were reviewed.ELG is rare in clinic. The etiology and pathogenesis of ELG was unclear.The clinical feature includes enlarged lymph nodes which were always predilected for the head and neck regions,eosinophilic granulocytes and serum IgE rising.Lymphoid tissue hyperplasis formation of lymphoid follicles with active germinal centres are common in pathological examination.There is diffuse infiltration of eosinophils in interfollicular and perivascular zones. Surgery,drug therapy and radiotherapy are all effective for the treatment,but recurrence is often.
ABSTRACT
Objective: To compare the phenotype of induced dendritic cell (DC) derived from peripheral blood of the healthy individuals and the patients with oral carcinoma. Methods:15 patients with oral carcinomal at stages II or above were assigned to study group and 15 cases of healthy volunteers were assigned to control group. Leukocyte were isolated by density centrifugation. Adherent fractions were incubated in present of GM-CSF,IL-4 and TNF-? for 7 days in vitro. The morphological change of the cultured cells was observed by light microscopy and electronic microscopy. The phenotype expressions of CD83,CD1a,CD86, CD80, HLA-DR were analysized by flow cytometry. Results:Typical DCs were obtained from two groups after 7 days culture. The expression rate of CD83,CD1a on DC from healthy volunteers was significantly higher than that from patients (P0.05). Conclusion:DC derived from oral cancer patient' s peripheral blood monocyte might be more matured and is a good cell model for further immunotherapy and research.
