摘要
Abstract
Objective: To evaluate the apoptosis positivity, the expression of Bcl-2, bax proteins in 30patients with squamous cell cervix carcinoma before and after radiotherapy. Methods: By using immunohistochemical and TDT-dUTP nick end labelling techniques, 30 cases of squamous cell cervical carcinoma were analyzed. Results: The apoptosis positivity before and after irradiation was 76.7% and 100% respectively, with the difference being significant (P<0.05); The positive rates of Bcl-2 protein before and after irradiation were 73.3% and 46.7% respectively, with the difference being significant (P<0.05); The positive rates of bax protein before and after irradiation were 86% and 100% respectively, with the difference being significant (P<0.05). Conclusion: bax and Bcl-2 protein play an important role in apoptosis induced by fractionated radiation therapy. Apoptosis induced by irradiation is contributed to upregulation of bax protein or downregulation of Bcl-2 protein.关键词
