We characterized smooth muscle function in the rabbit vas deferens in vivo by means of a new strainometer. Intraluminal pressure was measured and smooth muscle tension in the wall was calculated. Our studies revealed a low baseline pressure, no spontaneous contractions, and a constant wall tension. Studies of the effect of vasectomy on in vivo smooth muscle function showed increased intraluminal pressure, diameter, and baseline wall tension, and development of spontaneous contractions with increased wall tension, intraluminal pressure, and diameter with each contraction.
我们通过一种新型应变仪对兔输精管平滑肌功能进行了体内特征分析。测量了管腔内压力,并计算了管壁中的平滑肌张力。我们的研究显示基线压力较低,无自发收缩,且管壁张力恒定。输精管切除术对体内平滑肌功能影响的研究表明,管腔内压力、管径和基线管壁张力增加,且随着每次收缩,管壁张力、管腔内压力和管径增加时会出现自发收缩。
