本文报告将Teflon植于猫中耳腔内,用光镜及扫描电镜定期观察Teflon材料本身和与其相接触的中耳组织的病理改变,并同时监测机体免疫系统的变化。结果表明,Teflon在中耳内除引起持续性的局部排斥反应外,还能使机体免疫系统变得活跃。提示Toflon是一种生物相容性较差的材料。
In this paper, Teflon was implanted in the ear cavity of cats. The pathological changes of Teflon material itself and the middle ear tissues contacted with it were observed regularly with light microscope and scanning electron microscope, and the changes of the immune system were also monitored. The results show that, Teflon in the middle ear in addition to causing persistent local rejection, but also make the body’s immune system becomes active. Tip Toflon is a less biocompatible material.
