胃病时有胃肠道肽类的变化,特别是胃癌患者变化更为明显,这些肽类的变化可为临床诊断、治疗和观察预后提供依据。为确定胃病时某些胃肠道肽类的变化及意义,本文用放射免疫法联合测定血清胃液物质 P(SP)、β-内肽腓(β-EP)和血管活性肠肽(VIP)的含量,着重研究它们在胃癌时的变化及意义。材料和方法一、对象:67例住院患者中包括中晚期胃癌患者25例(腺癌21例、其它癌4例);男18例、女
There are changes in gastrointestinal peptides in the stomach, especially in patients with gastric cancer. Changes in these peptides can provide a basis for clinical diagnosis, treatment and observation of prognosis. In order to determine the changes and significance of certain gastrointestinal peptides in gastric diseases, this article used radioimmunoassay to jointly determine the contents of serum gastric substances P (SP), β-endopeptide quinine (β-EP) and vasoactive intestinal peptide (VIP). Content, focusing on their changes in gastric cancer and its significance. Materials and Methods 1. Object: Among the 67 hospitalized patients, 25 were middle and advanced gastric cancer patients (21 adenocarcinomas and 4 other cancers); 18 males and females.
