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】目的探討外科手術治療原發性肝癌致阻塞性黃疸的方法及療效。方法自1991年1月至2001年12月期間我院對17例原發性肝癌致阻塞性黃疸的患者進行外科手術治療，其中行肝葉切除及膽總管切開取癌栓者14例,行同種異體原位肝移植術3例。結果患者平均生存時間為8個月,最長24個月。結論外科治療原發性肝癌致阻塞性黃疸明顯改善了患者生活質量,延長了生存時間。
