Description

Objective: To study the radiosensitivity of tamoxifen to the human glioma cell lines SHG-44. Methods: 3H-TdR incorporation assay was used to detect DNA synthesis in glioma cells SHG-44, which were exposed to 60Co γ-irradiation with 0,1,3,5,7,9 Gy. When T lymphocyte and B lymphocyte from human peripheral blood were stimulated by phyto- agglutinin (PHA) and lipopolysaccharide (LPS), the effect of tamoxifen on proliferation of T lymphocyte and B lymphocyte was assessed by the same method. Results: Tamoxifen shifted the radiation dose-response curve to the left, with the decrease of D0 values. Tamoxifen(2-8 μmol/L) shows no significant inhibitory effects on proliferation of T lymphocyte and B lymphocyte, and there was no significant difference between TAM group and the control group (P>0.05). Conclusion: Tamoxifen could increase radiosensitivity of glioma cells SHG-44 to γ-irradiation, and it had no effect on the proliferation of T lymphocyte and B lymphocyte at the concentration of 2-8 μmol/L.
