Methods： A total of 207 surgical specimens diagnosed as NSCLC were included in this study. Double-staining procedures were performed using antigen Ki-67 （clone MIB-1） and silver nitrate by immunohistochemical and AgNOR-staining methods. Results： The AgNOR area in MIB-l-positive cells of NSCLC is related to clinicopathological parameters under the TNM （tumor, node, and metastasis） system. The survival of patients with small AgNOR area in MIB-1-positive cells is better than that of patients with large AgNOR area. Molecular, biological （AgNOR area in MIB-l-positive cells）, and clinicopathological （greatest tumor dimension, metastases to regional lymph nodes, histology, and differentiation） parameters are independent prognostic factors of NSCLC.Conclusion： The AgNOR area in MIB- 1-positive cells is related to clinicopathological parameters and survival in NSCLC.展开更多

The results indicated that during the course that the normal colonical mucosa developed to colorectal adenocarcinoma via adenoma the DNA and AgNOR protein contents increased gradually and there were very significant correlationships between the DNA and the AgNOR protein contents of adenoma group and adenocarcinoma group. However, there were considerahle overlaping in the DNA or AgNOR Protein content and considerahle overlaping cases between adenoma and normal colonic mucosa groups and between adenoma and adenocarcinoma groups. But the overlaping scope in NDA and AgNOR Protein content and the number of overlaping cases were reduced significantly by assessing the correlationship between the DNA and AgNOR protein content. Therefore, it is much more reliable to distinguish colorectal adenomas from adnocarcinomas by using the correlationship between the cellular DNA and the AgNOR Protein contents in the same specimens.展开更多
