ABH血型物质是一种具有抗原性的粘多糖,为胃肠道粘液的组成成分。以前的研究发现,ABH血型物质非分泌者十二指肠溃疡的发生率比之分泌者高1.5倍。但是这些研究仅按血型物质的非分泌者与分泌者两组来进行比较。实际上,真正的非分泌者是极罕见的。消化性溃疡的发生与ABH血型物质的含量之间有何关系?血型物质在其他慢性胃病时状态如何?文献中尚缺乏研究。
ABH blood group substance is an antigenic mucopolysaccharide, which is a component of gastrointestinal mucus. Previous studies have found that the incidence of non-secretory ABH blood group duodenal ulcer 1.5 times higher than those secreting. However, these studies only compare the two groups of non-secretors and secretors for blood group substances. In fact, the real non-secretor is extremely rare. What is the relationship between the occurrence of peptic ulcer and the content of ABH blood group substance? What is the status of blood group substance in other chronic gastritis?
