本文用直接荧光法研究42例胃癌组织和42例正常胃粘膜IgG产生细胞(简称IGPC)的分布密度。结果表明癌旁组织IGPC密度显著高于癌组织、3cm远粘膜和正常胃粘膜。胃癌各部位组织IGPC密度与性别及Borrmann氏分型(进展期胃癌)无关。但癌旁组织IGPC密度与年龄、肿瘤大小、组织学类型及转移情况有关。老年组显著低于青年组、中年组;癌肿4cm以上组显著低于2～3.9cm组;未分化型显著低于分化型;淋巴结转移组显著低于淋巴结无转移组。
In this paper, the distribution density of 42 cases of gastric cancer tissues and 42 cases of normal gastric mucosal IgG-producing cells (abbreviated as IGPC) were studied by direct fluorescent method. The results showed that the density of IGPC in the adjacent tissue was significantly higher than that in the cancer tissue, 3cm in the distal mucosa and normal gastric mucosa. The density of IGPC in various parts of gastric cancer was not related to gender and Borrmann’s type (progressive gastric cancer). However, the density of IGPC in adjacent tissues was related to age, tumor size, histological type, and metastasis. The elderly group was significantly lower than the young group and the middle-aged group; the cancer group above 4 cm was significantly lower than the 2 to 3.9 cm group; the undifferentiated type was significantly lower than the differentiated type; the lymph node metastasis group was significantly lower than the lymph node-free metastatic group.
