초록
Objectives : The study was intended to investigate whether Iljoong-eum (IJE) significantly affects proliferation and growth of prostate cancer cells.Materials and Methods : In vitro, after the treatment of DU-145 and PC-3 cells with IJE, we performed Sulforhodamine B (SRB) method. In vivo, a total of 8 male nude mice subcutaneously transplanted with the PC-3 cell line were divided in 2 groups. An experimental group was given IJE orally at a dose of 4.29ml/kg per day from the 8th to 31st day following tumor injection. All mice were observed for 31 days, and sacrificed by CO2 gas asphyxiation at the end of the experiment. The mean tumor volume and body weight of both groups were compared using Student's t-tests.Results : In vitro, IJE inhibited significantly proliferation and growth of DU-145 cells and PC-3 cells. In vivo, IJE inhibited significantly proliferation and growth of PC-3 cells xenografted into athymic nude mice.Conclusions : Our data has shown that IJE is effective in suppressing the growth rate of prostate cancer cells.
