本文以α—醋酸萘酯为底物显示酯酶活性,在成年 ICR 小鼠肾酯酶的分布与 Abe 等人在狗、兔、大鼠肾所得的结果基本一致,即酶活性最强定位在近曲小管。第17天鼠胚肾和新生鼠肾皮质内带成熟的肾单位出现明显的酯酶活性,最强在近曲小管;而皮质外带肾单位分化程度较低,酯酶活性很弱,甚至无活性。这与 Wachsten 等人在新生豚鼠和大鼠肾所观察的结果一致。但酯酶的出现时间比 Hunter 和韩雪梅所报道的早些。
In this paper, α-naphthyl acetate as a substrate showed esterase activity in adult ICR mouse renal esterase distribution and Abe et al in dogs, rabbits, rats kidney results are basically the same, that is the most active enzyme located in the Near the convoluted tubule. On the 17th day, the mature nephron in rat kidney cortex and neonatal rat renal cortex showed obvious esterase activity, which was the strongest in proximal convoluted tubule. However, the cortical band nephron differentiation was low and the esterase activity was very weak. active. This is consistent with the observation by Wachsten et al. In neonatal guinea pigs and rat kidneys. However, esterase occurred earlier than Hunter and Han Xuemei reported.
