doi:10.3969/j.issn.1674-5817.2020.02.007

Abstract

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.
