近来,人们对应用耳科同种移植物而传播人类免疫缺陷病毒(HIV)及克-杰氏病(CJD)致病物的潜在危险性产生忧虑。已经证明应用同种移植组织和器官,如皮肤,肾脏和血液可传播HIV。最近,也有报告,接受经冻干与照射的尸体硬脑膜移植物,也可成为CJD致病原。HIV在室温下的含水环境中,可保持活性15天以上,甚至在55℃的条件下也可存活3小时。Resnick等在实验室发现,在0.5％次氯酸钠,70％乙醇和0.5％诺乃(nonidet)去污剂内暴露1分钟,就能使HIV灭活。4％甲醛也具有
Recently, there have been concerns about the potential risks of transmitting otitis media (HIV) and Creutzfeldt-Jakob Disease (CJD) pathogens using otological gut implants. It has been demonstrated that the use of allograft tissues and organs such as the skin, kidneys and blood can transmit HIV. Recently, there have also been reports that cadaveric dura mater graft subjected to lyophilization and irradiation may also be the causative agent of CJD. HIV remains active for more than 15 days in an aqueous environment at room temperature and can survive for 3 hours even at 55 ° C. Resnick et al. Found in the laboratory that HIV was inactivated by exposure to 0.5% sodium hypochlorite, 70% ethanol and 0.5% nonidet detergent for 1 minute. 4% formaldehyde also has
