摘　　要：目的：探讨大鼠肾小体发育中体积生长曲线的变化规律。方法：采用连续切片技术,光镜观察并结合体视学分析方法,对不同发育阶段大鼠肾小体的体积进行测量,定量研究肾小体体积的变化规律。结果：胚龄16 d 时逗号小体及 S 小体出现,胚龄18 d,出现了Ⅲ期和Ⅳ期肾小体,生后7 d,逗号小体及 S 小体消失,肾小体的体积从胚龄18 d 到生后40 d 大约增大86倍。结论：大鼠肾小体于胚龄16 d 发生,生后40 d 达到成年水平。Objective： To study the growth curve of renal corpuscles in the developing rats. Methods： Light microscopy and stereological methods were used to investigate the volume of the rat renal corpuscles at different developmental stages. Results ： Comma-shaped bodies and S-shaped bodies emerged at embryonic day 16 （E16）and renal corpuscles of stage Ⅲ and Ⅳ emerged at E18. Comma-shaped bodies and S-shaped bodies disappeared at postnatal day 7（P7）. The volume of renal corpuscles increased by approximately 86 folds from E18 to P40. Conclusion： Rat renal corpuscles are formed at E16 and become mature at P40.
