The influence of long (LD 16:8) and short (LD 8:16) photoperiods on the autonomic innervation of the ductus epididymidis and ductus deferens of Phodopus sungorus was studied using the glyoxylic acid-induced catecholamine fluorescence and acetylcholinesterase (ACHE) histochemical methods. ACHE-positive nerve fibres could be demonstrated in the smooth muscle layer along the whole sperm transporting duct, in the lamina propria and within the epithelium of the ductus deferens. The extent and intensity of enzymatic reaction did not change between LD 16:8 and LD 8:16 conditions. An adrenergic nerve plexus was found in the smooth muscle layer of the sperm transporting duct. Especially in the ductus deferens, the intensity of fluorescence and the number of adrenergic nerves decreased in animals kept at short photoperiods. The influence of androgens on the sympathetic innervation of the ductus epididymidis and ductus deferens was discussed.
采用乙醛酸诱导的儿茶酚胺荧光法和乙酰胆碱酯酶（ACHE）组织化学方法，研究了长光照周期（16小时光照：8小时黑暗，LD 16:8）和短光照周期（8小时光照：16小时黑暗，LD 8:16）对黑线毛足鼠附睾管和输精管自主神经支配的影响。在整个精子输送管道的平滑肌层、固有层以及输精管上皮内均可显示出ACHE阳性神经纤维。在LD 16:8和LD 8:16条件下，酶反应的程度和强度没有变化。在精子输送管道的平滑肌层发现了一个肾上腺素能神经丛。特别是在输精管中，处于短光照周期的动物，荧光强度和肾上腺素能神经数量减少。文中还讨论了雄激素对附睾管和输精管交感神经支配的影响。
