| 目的对冻干人用狂犬病疫苗( MRC-5细胞)进行全身主动过敏试验、肌肉刺激性、单次给药毒性和溶血性评价，以考察其安全性。方法本研究起止时间为 2014年 3月至 2016年 10月。按照确定的工艺和质量标准，使用人二倍体细胞 MRC-5培养狂犬病固定毒株，灭活、纯化后制备冻干人用狂犬病疫苗，质量检定合格后，用于开展全面的动物毒理试验。结果在本试验条件下，含有人血白蛋白的赋形剂组、低剂量和高剂量疫苗组均会引起豚鼠过敏症状，第 14和 21天激发后病死率分别为 0(0/6)、 0(0/6)、 16.67%(1/6)和 33.33%(2/6)、 50.00%(3/6)、 33.33%(2/6)，三组病死率差异无统计学意义( P>0.05)，不含人血白蛋白的赋形剂组无过敏症状；单次或多次给药均不会引起家兔肌肉刺激性反应；最高剂量 50 IU/kg时，均未见明显的 ICR小鼠毒性反应；疫苗不会引起红细胞溶血和凝聚。结论动物试验表明，冻干人用狂犬病疫苗(MRC-5细胞)显示出良好的安全性。 |

| Objective To evaluate the safety of freeze-dried human rabies vaccine (MRC-5 cells) by performing active allergy test, muscle irritation evaluation, single administration toxicity and hemolytic.Methods The experimental study started and ended fromMarch 2014 to October 2016. Following the established processes and quality standards, rabies virus fixed strain was cultured in hu man diploid MRC-5 cell line, and then was inactivated and purified for preparing the freeze-dried rabies vaccine. After passing the QC test, the vaccine was used for a comprehensive animal toxicology test.Results In this experiment, excipients group containing humanalbumin, low dose, and high dose vaccine groups caused guinea pig allergy symptoms, the mortality rates after challenge on the 14thand 21st days were 0 (0/6), 0 (0/6), 16.67% (1/6) and 33.33% (2/6), 50.00% (3/6), 33.33% (2/6), there was no significant difference in |
