Abstract:
Objective To establish malignant biliary obstruction model on SD rats and to study the effects of Danshen injection on the growth of hepatocellular carcinoma, morphological change and the expression of proliferating cell nuclear antigen (PCNA) in carcinoma and peri-carcinoma tissues. Methods Malignant biliary obstruction model on SD rats was made by vaccination of transplanted tumor in the liver nearby the portal hepatis with Walker-256 hepatocarcinoma cell line which infiltrating and metastasizing to proximal common bile duct causing an obstruction. The SD rats were divided into four groups: those treated with 0.9% N S (n=12), with Inosine+VC (n=20), with Danshen (n=20) and with 5-FU (n=20), respectively. Results The growth and expression of PCNA in carcinoma, peri-carcinoma adjacent lobe tissues were significantly downgraded after treatment by Danshen injection compared with the rats treated by 0.9% N S and Inosine combined with Vitamine C and the infiltration was increased. The expression of PCNA in carcinoma, peri-carcinoma adjacent lobe tissues were downgraded compared with that of the rats treated by 5-FU while growth of hepatocarcinoma was slightly downgraded after treatment with Danshen injection. Conclusion Danshen shows protective effects on morphological change in SD rat model of malignant biliary obstruction. It can also inhibit the growth of hepatocarcinoma through inhibiting the proliferation of hepatocarcinoma cells and increasing reversion of hepatocarcinoma cells.
