ABSTRACT
Objevtive To investigate the safety of laparoscopic resection and ~(125)I seed implantation for recurrent gynecologic malignancies. Methods Laparoscopic surgery and ~(125)I seed implantation were used in five patients. All complications were recorded. Environmental radiation dose was detected at different distance from radioactive source and different time after operation with-γ-ray equipment. Results The procedure was safely achieved in all five patients. No serious complication was found. All patients experienced slight pain at the implant site and temporary vulva dropsy. With the increase of the distance from radioactive source and time passing, the radiation dose decreased quickly. The detected dose was close to a natural background radiation dose at the distance of 50cm from radioactive source and after 6 months. Conclusions Laparoscopic resection and ~(125)I seed implantation are safe to patient and environment.
ABSTRACT
Objective To study the security in HBV carried infertility patients during the in-vitro-fertilization procedure. Methods Serologic testing of HBV infection (HBsAg, HBsAb, HBeAg, anti-HBe, anti-HBc-IgG) of blood, follicle fluid/sperm and fertilization culture medium/post-washing sperm in female/male carried patients were detected by ELISA on the day of oocytes collection. Results In 18 female patients who were seropositive for HBsAg, HBeAg and anti-HBc-lgG, the same antigen and antibody could be detected in all 18 folli-cle-fluid and fertilization culture medium(100%, 100%). In 131 female patients who were sernpesitive for HBsAg, anti-HBe, anti-HBc-IgG, the same antigen and antibody could be detected in 84 follicle-fluid(64. 1%), and 8 fertilization culture medium(6. 1%). If the patients'follicle-fluld was negative for all the markers, their fertilization culture medium remained negative. In 23 male patients who were sero-positive for HBsAg , HBeAg,and anti-HBc-lgG, the same antigen and antibody could be detected in only 6 sperm (26. 1%), all the postwashing sperm were exhibited negative. In 121 nude patients who were seropositive for HBsAg, anti-HBe, anti-HBc-lgG, the same antigen and antibody could be detected in only 7 sperm (5. 8%), and all the post-washing sperm were negative. Conclusion In IVF-ET procedures, the risk of HBV transmission by follicle-fluid and fertilization culture medium in those female patients who showed serepesitive for HBsAg , HBeAg, and anti-HBc-lgG can not be decreased. The risk in those female patients who showed seropositive for HBsAg, anti-HBe, anti-HBe-lgG and male patients in IVF-ET procedures can be decreased.
