Effect of TGZ on the expression of VEGF and CD34 within the tumor. (A) Immunohistochemistry for VEGF was performed using the primary tumor sections. The values given in photographs show the VEGF-labeling index and are the means ± SE for five determinations in the control group and ten determinations in the TGZ group. *p < 0.05 (compared with the control group). Magnification: ×400. (B) Immunohistochemistry for CD34 was performed using the primary tumor sections. MVD was assessed in the tumor sections stained with the anti-CD34 antibody The values given in photographs show the MVD and are the means ± SE for five determinations in the control group and ten determinations in the TGZ group. **p < 0.01 (compared with the control group). Magnification: ×400.
