摘要：研究实验性隐睾术后大鼠附睾的AKP、ACP和SDH活性的动态变化。结果表明；①由于正常附睾管头段与尾段的差别，使隐睾术后附睾管头段与尾段AKP活性的差异性，这种差异说明隐睾后附睾管在物质代谢和功能上的不同，②ACP活性在头段附睾管上皮呈强阳性反应，而尾段在术后1～10天较正常增强，呈强阳性，自15天始逐渐减弱，说明术后早期上皮细胞的功能活动增强显著；③SDH活性，在术后1～2天附睾管头段上皮中稍增强，第3天始恢复正常，尾段管上皮活性变化不明显。

Abstract：The dynamic changes of aKP, ACP and SDH activities of rat＇s epididymis after artificial cryptorchidism were studied. In turned out that ①the difference between the head part and the end part of normal epididymis duct caused the difference of AKP activity of them. This difference indicates that there is a difference in substance metabolism and function of the epididymis duct after artificial cryptorchidism; ②ACP activity showed a strong positive reaction in the epithelial of the head part of epididymis duct, while the ACP activity in the end part of epididymis duct increased 1-10 days after operation compared with the control group, and appeared positive and it became weaker from the 15th ady. This indicates that there is a significant increase of the function of the epithelial cells in the early stage after operation; ③There was a slight increase of the SDH activity in the epithelial of the head part of epididymis duct 1-2 days after operation and it became normal from the 3rd day. And there was no obvious SDH activity in the epithelia of the end part.
