Abstract
Objective To observe the effect of Ad-bTERTp-HSV-TK/GCV system on malignant ascites of mice and probe into its mechanism of action.Methods The SX1 inbred strain mice were injected with H22 cell line of liver cancer and were divided into 4 groups at random.The mice in each group were given corresponding treatment after 48 hours.The production of ascites and survival period were evaluated. The apoptosis rates of tumor cells were detected by FCM.Morphological changes of tumor cells were studied by electromicroscope.Results Compared with other groups.Ad-hTERTp-HSV-TK/GCV Can obviously inhibit the production of ascites(P<0.01),prolong the survival period (P<0.01),and apoptosis rate in this group (27.12±2.12)% was significantly higher than that in other groups.No obvious side effect Was found during the treatment.Conclusion Ad-hTERTp-HSV-TK/GCV system Can inhibit production of ascites and prolong the survical period of mice by inducing apoptosis of hepatoma cells,which is a safe and feasible treatment for hepatoma therapy.
