１３１Ｉ was labeled on lipiodol molecule by an iodine exchange reaction. The labeling rate was 95%. No dehalogenation was detected within 15 days at room temperature or after slerilization. Animal experiments showed that after hepatic arteial injection, １３１Ｉ-lipiodol was selectively accumulated in the embolizated local area. No increased acti-vity was observed in thyroid, lung or other areas in the body. The blood radioactivity per ml was 0.09±0.04% of the injectd dose. The result suggest that １３１Ｉ-lipiodol is very stable and suitable for clinical application.
【摘要】目的探讨外科手术治疗原发性肝癌致阻塞性黄疸的方法及疗效。方法自1991年1月至2001年12月期间我院对17例原发性肝癌致阻塞性黄疸的患者进行外科手术治疗，其中行肝叶切除及胆总管切开取癌栓者14例,行同种异体原位肝移植术3例。结果患者平均生存时间为8个月,最长24个月。结论外科治疗原发性肝癌致阻塞性黄疸明显改善了患者生活质量,延长了生存时间。
