齿龈内阿米巴体内吞噬能力与毒性分析

Phagocytosis Ability and Toxicity Analysis of Entamoeba gingivalis in Vivo

摘要: 齿龈内阿米巴具有吞噬作用，在机体内可引发免疫反应，对机体提供保护。本研究通过分离口腔齿龈阿米巴，利用体外培养技术制备齿龈阿米巴悬液，通过腹腔注射的方法检测其对小鼠腹腔外源细胞的吞噬作用，并观察其在体内环境下对外源细胞的吞噬能力。结果表明，齿龈阿米巴在体内仍然具有较强的吞噬能力，同时也对机体产生一定的攻击作用，其双重效应是与机体长期共生的必然结果。

Abstract: Entamoeba gingivalis (E.g.) with phagocytosis ability can cause an immune response and then provide protection to the body. We cultured separated E.g. in vitro and prepared the E.g. suspen-sion, and then by intraperitoneal injection method to detect the phagocytosis of mice celiac ex-ogenous cells, and observe the in vivo environment for the phagocytosis of foreign cells. Results show that the E.g. in the body still has strong phagocytosis ability, but also the attack on the body produce certain effect; the double effect is the inevitable result of the long-term symbiosis with the body.
