Abstract:
Objective To investigate the expression of indu ci ble initric oxide synthase(iNOS) in gastric carcinoma and its relationship with angiogenesis and the prognosis. Methods Immunohistochemical staining method was used to det ect the expression of iNOS, VEGF CD34 in gastric carcinoma. Results The positive expression of iNOS in gastric carcinom a was 58.70% and iNOS was not detected in normal gastric tissue. The rate of the positive expression of iNOS in stage Ⅳ was higher than that in stageⅠ~Ⅲ. Th e positive expression of iNOS in gastric carcinoma with lymph node metastasis wa s higher than those with no metastasis. The MVD was 59.88? 18.02/HP and 55.5 9+ 19.39/HP in gastric carcinoma positive for iNOS and VEGF, repectively, obviou sly higher than those with negative expression of iNOS and VEGF, repectively ( P
