1.ADAMANTINOMA OF LONG BONES
Journal of Xi'an Jiaotong University(Medical Sciences) 1981;0(03):-
Adamantinoma of long bones is very rare. Approximately more than 100 cases have been reported in the literature, but only 3 cases in this country. This paper reports 2 cases adamantinoma of the tibia.The pathological characteristics of the tumor are: 1) basal-cell carcinomatous, 2) glandular, 3) tubular ( of varying sizes), and 4 ) squamous metaplasia. The origin of the tumor in controversial. We support the theory of its epithelial origin.
2.EFFECTS OF ABERRANT HLA-DR ANTIGEN EXPRESSION ON THYROCYTES
Journal of Xi'an Jiaotong University(Medical Sciences) 1982;0(04):-
Tru-cut specimens of thyroid tissue from 37 cases of autoimmune thyroiditis, 23 cases of hyperthyroidism and 13 cases of thyrotoxicosis with thyroiditis were analyzed by immunohistochemistry using monodonal antibody specific for HIA-DR antigen. Results showed that thyroid epithelial cells aberrant expressed DR antigen and the number of DR~+ thyrocytes was significantly increased in thyroid gland with intense lymphocytes infiltration and severe destruction of throid architecture. The data suggest that TSH, thyroglobulin antibodies, thyroid microsomes antibodics can bring some stimulation HLA-DR antigen expression in thyrocytes.

A morphologic and immunohistochemical studies were performed on the thyroid tissue of 13 thyrotoxicosis with thyroiditis(TTOT) and 9 hashimotoxocosis(HSHT). We found that the inflmmatory injure in HSHT was stronger than that in TTOT, and also, there were (?)ore infiltrating cells and activated T cells in HSHT (?) that in TTOT. Nevertheless, in both HSHT and TTOT, most of the infiltrating mononclear cells were T lymphocytes, and the proportion of T cell subsets, B lymphocytes and macrophages were almost the same, suggesting there might. be similar immunopathogencsis in these two diseases.
