采用新近问世的小型封闭式高效紫外线消毒器,照射模拟牙具表而,对细菌的杀灭和乙型肝炎病毒(HBV)的灭活结果为:照射1分钟能杀灭99.9％以上的非芽胞菌,2分钟能杀灭包括芽胞菌在内的所有试验菌,杀灭率达100％。照射仅60秒钟HBcAg完全被灭活,1分钟时能使HBcAg和人聚白蛋白受体(PHsAr)强阳性的血清和纯化的HBV Dane颗粒灭活率达99％以上,4分钟时灭活率几乎可达100％。HBcAg和PHsAr完全灭活均较HBcAg所需时间短。结果表明,这种近距离、高强度照射的消毒器具有迅速、高效杀灭细菌和灭活病毒的作用。同时说明,PHsAr和HBcAg作为检测指标并配合HBsAg,能全面反应紫外线的消毒作用,而不宜仅以HBsAg作为消毒灭活病毒的指标。
The use of a newly introduced small enclosed high-efficiency UV sterilizer that irradiates a simulated tooth table shows the killing of bacteria and the inactivation of Hepatitis B virus (HBV) as follows: irradiation for 1 minute can kill more than 99.9% of non- , 2 minutes to kill all bacteria, including Bacillus, kill rate of 100%. HBcAg was completely inactivated only 60 seconds after irradiation, and the inactivation rate of HBcAg and human poly albumin receptor (PHsAr) -positive serum and purified HBV Dane particles was over 99% at 1 minute, and was inactivated at 4 minutes Rate is almost 100%. The complete inactivation of HBcAg and PHsAr was shorter than that of HBcAg. The results show that this close-range, high-intensity disinfection of sterilization with a rapid and efficient kill bacteria and inactivate the role of the virus. At the same time, PHsAr and HBcAg as detection indicators and with HBsAg, can fully reflect the disinfection of UV, and should not only HBsAg as an indicator of disinfection inactivated virus.
