摘　　要：目的观察光触媒瓷砖对流感病毒和脊髓灰质炎病毒的灭活效果。方法采用细胞培养法和基因扩增法,对光触媒瓷砖灭活流感病毒和脊髓灰质炎病毒的效果进行检测。结果光触媒瓷砖上分别污染的两种病毒在荧光灯下照射作用4h,对H3N2型流感病毒灭活对数值为1.66 TCID50;对脊髓灰质炎病毒Ⅰ型疫苗株灭活对数值为0.33 TCID50。光触媒上的病毒在无光照条件下作用4 h,病毒灭活对数值分别只有0.15 TCID50和0.05 TCID50。结论光触媒瓷砖在光照条件下对污染的流感病毒和脊髓灰质炎病毒具不同程度的灭活效果,但其对两种病毒的核酸无破坏作用。Objective To observe the inactivation efficiency of photocatahic ceramics tile on influenza and poliomyelitis virus. Methods The inactivation efficiency of photocataltic ceramics tile on virus was detected by cell cultural and real - time PCR techniques. Results The inactivation logarithm values of influenza and poliomyelitis virus polluted on the photo- cataltic ceramics tile were 1.66 TCID50 and 0. 33 TCID50 respectively after being under the fluorescent light for 4 hours. Those of influenza and poliomyelitis virus polluted on the photocataltic ceramics tile without lighting for 4 hours were 0. 15 TCID50 and 0. 05 TCID50 respectively. Conclusion The photoeataltic ceramics tile can inactivate influenza and poliomyeli-tis viruses to some extent under fluorescent light, but can not damage the virus nucleic acid.
