Methods The distribution character and pattern of apoptosis in normal and discoid lupus erythematosus(DLE) of oral mucosa were evaluated by in situ terminal deoxynucleotidy transferase(TDT) end labeling staining (TUNEL) and ABC immunohistochemical proliferating cell nuclear antigen(PCNA) labeling.

Objectives: To detect the expression of GR-α, GR-βand MT1 in healthy scalp and the lesions of alopecia areata and scalp DLE through immunohistochemistry, to explore the influence of them in growth of follicles and explain the effect and significance in relevant diseases.
