摘要: 目的 研究幼龄SPF级SD大鼠自发性病变的发生情况,为药物临床前安全性评价研究特别是儿科药物临床前评价研究提供资料。方法 收集近2年幼龄SD大鼠药物重复给药毒性研究试验中出生51 d(PND51)、出生65 d(PND65)、出生111 d(PND111)、出生139 d(PND139)阴性对照组大鼠,制作病理切片,光学显微镜下观察SD大鼠病变的种类及组织形态学特点,并统计其病变发生率。结果 分析报告了幼龄SPF级SD大鼠发育不同时间的自发性病变,主要有心脏、肝脏、肾脏等脏器病变,其中肝脏、心脏、肾脏自发性病变发生率及程度随着大鼠的发育有所提高和加深。结论 幼龄SPF级SD大鼠发育不同时间的自发性病变及其发生率可为药物重复给药毒性研究提供参考。

Abstract: Objective To study the incidence of spontaneous histopathological lesions of young SPF SD rats at different growth and development stages, to provide information for drug nonclinical safety evaluation especially for pediatric drugs. Methods The samples were collected from SD rats in day 51 (PND51), day 65 (PND65), day 111 (PND111) and day 139 (PND139) after born as control groups in safety evaluation studies in recent 2 years. The pathological sections and histomorphological features of SD rats were observed under an optical microscope, and the incidence of pathological changes was also observed. Result The spontaneous lesions of young SPF SD rats at different times were analyzed and reported. The high incidence lesions occurred mainly in heart, liver, kidney and other organ lesions. The incidence and levels of spontaneous histopathological lesions of liver, heart and kidney were increased and developed with the rats growing. Conclusion The spontaneous lesions and their incidence in young SPF SD rats in drug toxicology research can provide some reference for relevant scientist.
