ABSTRACT
Objective: To investigate the effect of Shenmai Injection (Radix Ginseng Rubra, Radix Ophiopogonis) on angiogenesis and the expression of proliferating cell nuclear antigen (PCNA) in tumor tissue, and the mechanism of it in the treatment of tumor. Methods: The mouse tumor model was used to investigate the effect of Shenmai Injection on tumor growth on the whole. The expression of von Willebrand factor (vWF) and PCNA in tumor tissue was studied by means of immunohistochemistry. Results: Shenmai inhibited the tumor growth and reduced microvessel density and the expression of PCNA in tumor tissue. Conclusion:Antiangiogenesis is one of the mechanisms of Shenmai Injection in treatment of tumor.
ABSTRACT
AIM: To investigate the effect of Shenmai Injection on the expression of bFGF and PCNA of gastric cancer in mouse. METHODS: RT-PCR was used to measure the expression of bFGF and PCNA in gastric cancer cell cultured with Shenmai Injection in three concentrations.immunohistochemistry used for protein synthesis in mouse gastric cancer model. RESULTS: 140 ?L/mL of Shenmai Injection concentration inhibited 63% of bFGF and PCNA gene expression. CONCLUSION: Shenmai Injection can inhibit the express of bFGF and PCNA.
