乳铁蛋白(Lactoferrin)是一种从母牛、人类乳汁和多种外分泌液中分离出来的含铁蛋白质,生理作用还不清楚,可能与肠道铁吸收有关。以前已发现胰液中的乳铁蛋白变化与胰腺疾病有关。作者采用放射免疫法估价其在胰腺疾病中的价值。接受研究的40例患者,其中19例确诊为慢性胰腺炎,10例胰腺癌,余11例X线及生化测定正常作为对照组。选择性胰导管插入后,静注胰泌素1临床单位/公斤体重后2分钟采集纯胰液5～10毫升做乳铁蛋白 Lactoferrin, an iron-containing protein isolated from cows, human milk and various exocrine fluids, remains unclear and may be related to intestinal iron absorption. It has previously been found that changes in lactoferrin in pancreatic juice are associated with pancreatic disease. The authors used radioimmunoassay to assess its value in pancreatic disease. Of the 40 patients studied, 19 were diagnosed as chronic pancreatitis, 10 had pancreatic cancer, and the other 11 had normal X-ray and biochemical tests as controls. Selective pancreatic catheterization, intravenous injection of secretin 1 clinical units / kg body weight 2 minutes after collecting pure pancreatic juice 5 to 10 ml of lactoferrin
