RESUMO
Objective To detect the expression of RXR? gene protein in gastric cancer, superficial gastritis, normal gastric mucosa, in order to explore the relationship between the development of gastric cancer, combined with clinical and pathological analysis of its clinical significance. Methods Using immunohistochemical detection RXR? protein in gastric cancer, superficial gastritis, gastric mucosa in the normal expression. Results RXR? protein mainly located in the nucleus of cells, there are a small number of cytoplasmic staining, a brown or yellow granular, in gastric cancer, superficial gastritis, normal gastric mucosa, RXR? protein expression rates were 25.0%, 81.1%, 96.1%; group and the normal mucosa and superficial gastritis, gastric cancer group RXR? expression rate has dropped, there were significant differences (P0.05). The lymph node metastasis and tumor pathology and clinical phases closely related (P
RESUMO
AIM: To study the pathological change in mouse organs immunitied by inactivated SARS-CoV vaccine. METHODS: Inactivated SARS-CoV vaccine was injected into BALB/c and C57BL/6 mice. Anti-SARS antibody was analyzed by ELISA. After 8 weeks, the immunitied mice were killed and those organs were analyzed by pathological methods. RESULTS: Anti-SARS antibody in mice was positive after 8 days. Only minimal injury was observed in a few lungs and livers, but the other organs were not. CONCLUSIONS: Inactivated SARS-CoV vaccine induced mice to create antibody, whereas they did not cause severe injury. This result will be valuable for vaccine into clinical research. [
