The presence of adrenergic nerves in the Eustachian tubes of guinea pigs was observed using the Falck-Hillarp fluorescence method. Abundant adrenergic nerve are forming networks around blood vessels in all tubal regions. Adrenergic fibers also surround the tubal glands. The precise locations of adrenergic nerve terminals in the tube were demonstrated by electron microscopy following application of a false transmitter. Adrenergic nerve terminals were found in abundance just beneath the smooth muscle layer of the arteries in each part of the tube and close to the myoepithelial cells of the tubal gland.
采用福尔克-希拉尔普荧光法观察豚鼠咽鼓管中肾上腺素能神经的存在情况。在咽鼓管的所有区域，丰富的肾上腺素能神经在血管周围形成网络。肾上腺素能纤维也围绕着咽鼓管腺体。应用假递质后，通过电子显微镜确定了咽鼓管中肾上腺素能神经末梢的精确位置。在咽鼓管各部分动脉平滑肌层下方以及靠近咽鼓管腺肌上皮细胞处均发现大量肾上腺素能神经末梢。
