交感神经纤维及其受体在眼前部房水动力组织中分布的研究,对于了解抗青光眼药物的作用机理、房水分泌及排出的生理过程和原发性开角型青光眼的发病机理等都有重大的意义。在本世纪60年代,这个问题已引起重视。利用组织化学荧光技术证明了在上巩膜组织、滤帘、睫状体血管和虹膜中有大量的含去甲肾上腺素的纤维。在电镜研究中也在上述组织中发现在突触空泡间有中心致密的空泡存在,说明有交感纤维的分布。本文综述了近年来国外利用电子显微镜、组织化学、荧光标记、药物作用、同位素标记等手段所获取的一些最新资料。这部分材料大都来
Sympathetic nerve fibers and their receptors in the anterior chamber of the hydrodynamic distribution in the study of the mechanism for understanding the anti-glaucoma drugs, aqueous humor secretion and discharge of physiological processes and primary open-angle glaucoma pathogenesis, etc. Great significance. In the 1960s, this issue has drawn great attention. The use of histochemical fluorescence techniques demonstrated the presence of a large number of norepinephrine-containing fibers in the upper scleral tissue, filter curtains, ciliary body vessels and iris. In the electron microscopy study also found in the above-mentioned organizations in the synaptic vacuoles between the center of dense vacuoles exist, indicating the distribution of sympathetic fibers. This review summarizes some of the latest information obtained by foreign countries in recent years by means of electron microscopy, histochemistry, fluorescent labeling, drug action and isotope labeling. Most of this material comes
