胃的机能形态学与临床形态学主要研究胃的实质,而对胃的间质,包括胃内淋巴网状组织细胞系统的成分则研究得很少。后者对局部免疫反应和保持机体内环境的稳定性起很大作用。胃肠道粘膜几乎1/4是淋巴样组织,其机能与周围淋巴样组织的淋巴结以及脾脏相同。对消化系统淋巴样组织的详细研究可分为3组:1.位于上皮内的淋巴细胞;2.在粘膜固有层中弥漫性分布的淋巴细胞和浆细胞;3.位于粘膜基底的淋巴样滤泡。
The functional morphology and clinical morphology of the stomach mainly focus on the nature of the stomach, while little research has been done on the components of the gastric interstitium, including the intragastric lymphatic reticulum cell system. The latter plays a major role in the local immune response and maintaining the stability of the internal environment of the organism. Almost a quarter of the gastrointestinal mucosa is lymphoid tissue, and its function is the same as that of lymph nodes and spleen around the lymphoid tissue. Detailed studies of lymphoid tissue in the digestive system can be divided into three groups: 1. lymphocytes located within the epithelium; 2. diffusely distributed lymphocytes and plasma cells in the lamina propria; 3. lymphoid filtration located at the mucosal basement bubble.
