为观察99Tcm-DTPA进入动物消化系统后是否可被摄取进入其他器官以及Oddi氏括约肌经机械损伤后是否可随肠液反流到胆管 ,本文用大白鼠分别做了99Tcm -DTPA和99Tcm -PHY的胃肠显像及处死后测定内脏及血液内的放射性计数。再用两只猪做99Tcm-DTPA的胃肠显像及胆管引流术后胆汁内的
To observe whether 99Tcm-DTPA can be taken into other organs after it enters the animal’s digestive system and whether Oddi’s sphincter can be refluxed with intestinal fluid to the bile duct after mechanical injury. In this paper, the stomach of 99Tcm-DTPA and 99Tcm -PHY Intestinal development and after sacrifice determination of visceral and blood radioactivity count. Then use two pigs to do 99Tcm-DTPA gastrointestinal imaging and bile drainage after biliary drainage
