Abstract

Smooth muscle electrical activity was recorded simultaneously with intraluminal pressure in the cauda epididymidis and epididymal vas of the rat in vitro. Spontaneous electrical activity spread over distances of several centimetres and was associated with a pressure wave recorded through an open-ended catheter in the distal cauda and epididymal vas. Transmission of pressure wave was gradually damped by filling of the catheter with spermatozoa.

摘要

在体外对大鼠附睾尾部和附睾管的平滑肌电活动与腔内压力进行同步记录。自发电活动可传播数厘米的距离，并与通过置于附睾尾部远端和附睾管的开口导管记录到的压力波相关。随着精子充满导管，压力波的传播逐渐受到抑制。
