The structure of gingival mucous membrane leukocytal infiltration of 80 patients with chronic apical periodontitis of different age groups was studied by the light microscopy with the use of monoclonal antibodies to CD38. It was disclosed that in gingival tissues of practically all patients 2 types of leukocytal infiltration were present with low number of plasmatic cells and high number of neutrophils (true leukocytal infiltration) and structures with high number of plasmatic cells and low number of neutrophils - most likely lymphoid follicle resultant in mucous membranes of different organs in cases of chronic inflammation. In epithelial gingival paving in cases of chronic apical periodontitis CD38(+)-cells were absent.
采用抗CD38单克隆抗体，通过光学显微镜研究了80例不同年龄组慢性根尖周炎患者牙龈黏膜白细胞浸润的结构。结果显示，几乎所有患者的牙龈组织中都存在两种类型的白细胞浸润：一种是浆细胞数量少、中性粒细胞数量多的真正白细胞浸润；另一种是浆细胞数量多、中性粒细胞数量少的结构——很可能是慢性炎症时不同器官黏膜中形成的淋巴滤泡。在慢性根尖周炎患者的牙龈上皮铺路细胞中不存在CD38(+)细胞。
