title: [In vitro and in vivo effects of ginsenoside Rh2 on the proliferation of serous cystadenocarcinoma of the human ovary].
abstract: Inhibition of human ovarian cancer cell proliferation in vitro and in vivo by Ginsenoside Rh2(Rh2) isolated from Red Ginseng was examined by using a cell line (HRA) derived from ascites of a patient with serous cystadenocarcinoma of the ovary. The HRA cell proliferation in vitro was inhibited in a dose-dependent manner with between 10 and 100 microM of Rh2. The uptake of radiolabeled precursors (3H-thymidine, 3H-uridine, and 3H-varine) by HRA cells was also inhibited in a dose-dependent manner with between 30 and 100 microM of Rh2. The growth of HRA cells transplanted into nude mice was not significantly inhibited by Rh2 alone. On the other hand, when cisplatin was administered together with 10 microM, 30 microM, or 50 microM Rh2, the growth of HRA cells was inhibited 31 and 35 days after tumor inoculation. Survival was also prolonged when cisplatin was administered with 10 microM and 30 microM Rh2. These results suggest that there is a synergistic effect between cisplatin and Rh2.
