Effects of Danshen injection on the malignant obstructive jaundice in the SD rat model / 华中科技大学学报（医学）（英德文版）

ABSTRACT

To observe the effects of Danshen on the growth of hepatocellular carcinoma in the SD rats, a model of malignant obstructive jaundice was established by inoculation of transplanted tumor into the hepatic portal with the walker-256 hepatocarcine line, which resulted in the obstruction by the infiltration and metastasis of hepatocellular carcinoma. SD rats were divided into 4 groups the rats were treated by 0.9 % NS (n=24, control group), inosine+vitamin C (n=40, InV group), Danshen (n=40, DS group) and 5-FU (n=40, 5-FU group), respectively. The liver function, morphological changes and the expressions of PCNA, VEGF and ICAM-1 in carcinoma foci, peri-carcinoma tissues, adjacent lobe (left-internal lobe) and lung tissues were observed after the treatment with the 4 agents. Our results showed that the protective effect of Danshen on liver function was significantly better than that of NS and 5-FU (P0.05). Danshen also provided protective effect on the morphological damage of liver caused by obstructive jaundice. The rates of carcinoma-inhibition and metastasis inhibition were significantly higher than those of NS and inosine+vitamin C (P0.05). The expressions of PCNA,VEGF and ICAM-1 PCNA, VEGF and ICAM-1 in carcinoma foci, peri-carcinoma tissues, adjacent lobe (left-internal lobe) and lung tissues were lower than those in control group and InV group, with the differences being significant (P0.05) but ICAM-1 (P<0.05). It is concluded that Danshen injection not only has protective effects on liver injury caused by obstructive jaundice, but can inhibit the proliferation and growth of hepatocarcinoma, interfere with the vascularization of tumors, prevent recurrence and metastasis of hepatocarcineoma.
