中文摘要

目的研究牙周病致病菌牙龈卟啉单胞菌脂多糖(LPS)对体外培养的人牙周膜成纤维细胞(hPDLF)胶原吞噬作用的影响。方法将不同质量浓度的LPS加入体外培养的hPDLF 48 h后,采用荧光定位术和流式细胞技术检测hPDLF胶原吞噬率的变化。结果LPS导致hPDLF胶原吞噬率显著增加(P

英文摘要

Objective To investigate the effects of Porphyromonas gingivalis(P.gingivalis) lipopolysaccharide(LPS) on collagen phagocytosis of human periodontal ligament fibroblasts(hPDLF). Methods Fluorescence localization and flow cytometry was used to test the collagen phygocytosis of hPDLF stimulated by the various concentration of LPS for 48 hours in vitro. Results The collagen phygocytosis of hPDLF was increased significantly by 0.1 μg/mL LPS (P
