对三种牙髓塑化剂的抑菌性和溶血活性的评价

Evaluation of the bacteriostasis and the acute hemolytic activity in vitro of three sorts of resinifying agent

作者对ＦＲ、ＧＲ和ＲＦ１０９三种牙髓塑化剂进行了抑菌试验和溶血试验。抑菌试验的菌种为二种厌氧菌（牙髓类杆菌、中间型类杆菌）．一种微需氧菌（粘性放线菌）和三种口腔常见需氧苗（金黄色葡萄球菌、乙型溶血性链球菌和大肠杆菌）．结果显示：三种塑化剂的抑菌力依次为：ＲＦ１０９＞ＦＲ＞ＧＲ。溶血试验显示：ＦＲ和ＧＲ不具溶血活性；而ＲＦ１０９则致溶血，说明ＦＲ和ＧＲ对组织较温和；ＲＦ１０９虽然抑菌力强，但同时对组织有较大的刺激性。

The bacteriostatic test for the anaerobic which had a direct bearing on pulpal-periapical infection and oral common aerobic bacteriosia were performed.The results indicated the bacteriosia ability of three sorts of resinify agent is in sequence:FR109>FR >GR.We found that FR and GR had no acute h emolyzation in the hemolytic test in vitro,but RF109 caused hemolysis.
