胃泌素是最早发现的一个胃肠道激素,它可以促进壁细胞分泌盐酸,并对胃肠道粘膜有营养作用。近一年来我国已将胃泌素的放射免疫测定应用于临床。通过文献复习,发现胃泌素不仅存在于血清,同时也存在于胃液中。为了证实此问题,自去年4月以来,我们对25例胃肠道病人进行了胃液中胃泌素的测定,现将结果报道如下,并对其来源略加讨论。 Gastrin is one of the earliest discovered gastrointestinal hormones, it can promote parietal cells to secrete hydrochloric acid, and gastrointestinal mucosa with nutritional effects. In the past year, our country has already applied gastrin radioimmunoassay to clinical practice. Through literature review, found that gastrin not only exists in the serum, but also exists in the gastric juice. To confirm this issue, gastrodin determinations in 25 patients with gastrointestinal tract since April last year are reported below and the source is briefly discussed.
