摘要:

目的 为符合良好实验室规范(Good Laboratory Practice,GLP)要求,四川省药品检验研究院(四川省医疗器械检测中心、四川养麝研究所)安全评价中心(以下简称本中心)针对实验动物设施消毒剂、饲料、垫料使用过程中有效期规定缺乏数据支撑的问题,开展专项验证研究,总结物料管理实操经验,为设施物料规范化管理提供科学依据。 方法 在本中心实验动物设施日常运行环境下,对配制和开封后第0天、第7天、第1个月、第2个月和第3个月的4种常用消毒剂采用悬液定量杀灭试验确认其消毒效力;对开封后储存7 d的实验动物饲料进行营养成分、化学污染和微生物指标检测;对开封和灭菌储存7 d的实验动物专用玉米芯垫料进行微生物指标检测。 结果 在本中心GLP管理体系下,0.04%次氯酸钠溶液、0.1%癸甲溴铵溶液、0.2%苯扎溴铵溶液配制后和75%乙醇开封后第0天和第7天,75%乙醇开封后第1个月、第2个月和第3个月,其消毒剂效力杀灭对数值均≥5,均判定为合格有效。与出厂质检数据相比,开封7 d后的SPF级大小鼠维持饲料、SPF级豚鼠生长繁殖饲料、普通级豚鼠生长繁殖饲料、兔维持饲料、犬维持饲料的营养成分、化学污染和微生物指标,虽整体呈轻微下降趋势,但无明显差别,开封后储存7 d的SPF 级实验动物专用玉米芯垫料和经灭菌后储存7 d的普通级玉米芯垫料,微生物指标无明显波动,均满足GB/T 14924.2—2001《实验动物 配合饲料卫生标准》及GB 14924.3—2010《实验动物 配合饲料营养成分》的相关要求。 结论 结合本中心GLP实验动物设施管理实操经验,经核心质量指标检测验证,明确设定的消毒剂、饲料及垫料有效期满足质量要求,可为实验动物设施的规范化管理提供参考。

Abstract:

Objective To meet the requirements of Good Laboratory Practice (GLP), Sichuan Institute for Drug Control (Sichuan Testing Center of Medical Devices, Sichuan Institute of Musk Deer Breeding) Safety Evaluation Center (hereinafter referred to as the center) conducts a targeted validation study to address the lack of supporting data for the specified validity periods of disinfectants, feed, and bedding during their use in laboratory animal facilities. The study summarizes practical experience in material management and provides a scientific basis for the standardized management of materials in the facility. Methods Under the routine operating conditions of the laboratory animal facility at the center, the disinfection efficacy of four commonly used disinfectants was confirmed using the quantitative suspension kill test, with the disinfectants tested on day 0, day 7, and at 1, 2, and 3 months after preparation and after opening; for laboratory animal feed, nutritional components, chemical contaminants, and microbial indicators were tested 7 days after opening; microbial indicators of laboratory animal corncob bedding were tested after storage for 7 days following opening and sterilization. Results Under the GLP management system of our center, the disinfection efficacy log reduction values of prepared 0.04% sodium hypochlorite solution, 0.1% didecyldimethylammonium bromide solution, and 0.2% benzalkonium bromide solution were all ≥5 on days 0 and 7. The log reduction values of opened 75% ethanol were ≥5 on days 0 and 7 and at 1, 2, and 3 months after opening. All disinfectants were therefore qualified and effective. Compared with the factory inspection data, the nutritional components, chemical contaminants, and microbial indicators of SPF-grade rat and mouse maintenance feed, SPF-grade guinea pig growth and reproduction feed, conventional-grade guinea pig growth and reproduction feed, rabbit maintenance feed, and dog maintenance feed showed a slight overall downward trend but no significant differences 7 days after opening. The microbial indicators of specialized corncob bedding for SPF-grade laboratory animals stored for 7 days after opening and conventional-grade corncob bedding stored for 7 days after sterilization showed no significant fluctuations. All indicators still met the relevant requirements of GB/T 14924.2—2001 Laboratory AnimalsHygienic Standard for Formula Feeds and GB 14924.3—2010 Laboratory AnimalsNutrients for Formula Feeds. Conclusion Based on practical experience in managing the center's GLP laboratory animal facility and validation of core quality indicators, the specified validity periods of disinfectants, feed, and bedding meet the quality requirements, providing a practical reference for the standardized management of laboratory animal facilities.
