Spontaneous contractions of the adult rabbit isolated testicular capsule were found to be influenced by moderate hyperthermic and hypothermic temperature changes. The decrease in testicular capsular spontaneous contractions resulting from an exposure to 32, 40 and 42 degrees C have been shown to be influenced by the addition of NE, ACh and PGF2 alpha. Of the three neurohumoral agents studied, NE was found to cause the greatest increase and re-initiation of testicular capsular tone during both hypothermia and hyperthermia. These data indicate that endogenous levels of neurohumoral agents may play an important role in the maintenance of testicular capsular tone during exposure to hyperthermic or hypothermic conditions.
研究发现，成年兔离体睾丸白膜的自发收缩受适度的体温升高和降低的影响。暴露于32℃、40℃和42℃导致睾丸白膜自发收缩减少，已证实添加去甲肾上腺素（NE）、乙酰胆碱（ACh）和前列腺素F2α（PGF2α）会对其产生影响。在所研究的三种神经体液因子中，发现去甲肾上腺素在体温过低和过高时均能引起睾丸白膜张力最大程度的增加和恢复。这些数据表明，在暴露于高温或低温条件下时，神经体液因子的内源性水平可能在维持睾丸白膜张力方面发挥重要作用。
