癌胚抗原(CEA)最初认为是某些癌瘤所特有的抗原。进一步研究发现在良性疾患病人血清和体液中也存在。本文对慢性支气管炎(慢支)病人的支气管肺泡灌洗液(洗液)进行了CEA含量测定,结果报告如下。 材料和方法 一、研究对象:慢支病人38例,其中吸烟者21例,不吸烟者17例。 二、标本采取:(1)血清:取空腹血清0.5ml测定。(2)洗液:经鼻腔插入OLympus B:型纤维支气管镜直到右肺中叶开口,然后将导管进入中叶内或外段支气管,先灌入37℃无菌生理盐水10ml,再用6.7～13.4KPa负压回吸,如此灌洗3次,总灌入
Carcinoembryonic antigen (CEA) was originally thought to be specific to some cancers. Further study found that patients with benign disease serum and body fluids also exist. In this paper, bronchoalveolar lavage fluid (lotion) in patients with chronic bronchitis (chronic bronchitis) CEA determination, the results reported below. Materials and methods First, the study: 38 patients with chronic bronchitis, including 21 smokers, 17 non-smokers. Second, the specimens to take: (1) serum: Take fasting serum 0.5ml determination. (2) lotion: the nasal cavity into the OLympus B: type bronchoscopy until the middle of the right lung openings, and then the catheter into the middle or outer bronchus, first poured into 37 ℃ sterile saline 10ml, and then 6.7 ~ 13.4KPa Negative pressure suction, so lavage 3 times, the total infusion
