Abstract:
OBJECTIVE: To observe the influence of Xiaotan Sanjie Recipe on growth of the transplanted tumor and expressions of proliferating cell nuclear antigen (PCNA) and epidermal growth factor receptor (EGFR) in tissue of the gastric carcinoma of nude mice, and to explore the mechanism of Xiaotan Sanjie Recipe in restraining the multiplication of the stomach cancer. METHODS: MKN-45 gastric carcinoma model in nude mice was established. Forty-five nude mice were randomly divided into control group, Xiaotan Sanjie group and 5-fluorouracil (5-FU) group. Drugs were given on the next day of inoculation. Mice in the control group were given normal saline, and mice in the Xiaotan Sanjie group were given Xiaotan Sanjie Recipe. Intraperitoneal injection of 5-FU was administered in the 5-FU group. The expressions of PCNA and EGFR were examined by using streptavidin peroxidase (SP) conjugate technique, and the tumor weight and pathological characteristics were also observed. RESULTS: Compared with the control group, Xiaotan Sanjie Recipe significantly restrained the growth of the transplanted tumor, and reduced the expressions of PCNA and EGFR in tissue of the gastric carcinoma of nude mice (P<0.05). CONCLUSION: Xiaotan Sanjie Recipe can disturb the synthesis of DNA and reduce the proliferous activity of cancer cells by decreasing the expressions of PCNA and EGFR.
