Abstract:
Objective To study the effect of oxymatrine (OMT) combined with radiotherapy on the growth of HO8910 cells of human ovarian cancer in vitro.Methods All human ovarian cancer samples were divided into four groups:control group,treated with culture solution; OMT group,treated with 4 mg/ml OMT; radiotherapy group,treated by 4 Gy radiotherapy; and combination group,firstly treated by 4Gy radiotherapy,and then cultured with 4 mg/ml OMT.Observed the changes of cell morphology by invert microscope at 10,24,48,and 72 hours respectively.Flow cytometry was adopted to detect cell apoptosis.Results ① invert microscope observation showed that compared with the control group,HO8910 cells demonstrated apoptosis of diminution in volume,thickening in cytoplasm,and gathering in nucleus in all the other three groups at 24 and 48 hours.② Flow cytometry showed that apoptosis rate of HO8910 cells and cell population in G1 phase increased in the combination group,which were significantly higher than the other three groups (P＜0.05).Conclusion Both OMT (4 mg/ml)and radiation (4Gy)can induce cell apoptosis,while the combination of them showed better therapeutic results.
