摘要

本研究的目的是对人体颈上交感神经节(SCSGs)近端和远端两部分的微血管、肥大细胞和神经节神经元的分布进行微形态学分析。统计分析用于检测其密度可能存在的度量区域差异。用有色印度墨水和明胶注射 5 个人体 SCSG,并对其进行显微解剖和检查。制备第二组 5 个人类 SCSG,并将其连续切片用于 CD34 和肥大细胞胰蛋白酶免疫染色。对 SCSG 两个部分的显微镜视野进行以下量化分析:微血管密度(MVD)、肥大细胞密度(MCD)、神经节细胞计数和测量。显微视野中 CD34 阳性微血管的平均数量,即 MVD,SCSG 上部的值为 83,下部为 82.7。显微视野中胰蛋白酶阳性肥大细胞的平均数量(MCD)在 SCSG 的近端部分为 4.5 个,远端部分为 4.7 个。在显微视野中,神经节神经元的平均数量在SCSG近端为19.5个,远端为19.8个。CD34 阳性微血管的密度、胰蛋白酶阳性肥大细胞的密度、神经节神经元的密度、平均直径和平均面积在 SCSG 上部和下部的两个观察部位没有显著差异。总之,SCSG 两个部分的微血管、肥大细胞和神经元分布均匀,没有特殊的微观形态变化,SCSG 内部存在同质的血管和细胞模式。

Arterial supply and morphological characteristics of sympathetic neurons in the human superior cervical ganglion

The aim of this study was the micromorphological analysis of the distribution of microvessels, mast cells and ganglionic neurons in two parts, proximal and distal of the human superior cervical sympathetic ganglions (SCSGs). Statistical analyses were applied to detect the possible metric regional differences in their densities. Five injected human SCSGs with colored India ink and gelatin were microdissected and examined. Second group of five human SCSGs was prepared and serially sliced for CD34 and mast cell tryptase immunostaining. The microscopic fields of two parts of the SCSGs were analyzed for the following quantifications: microvessel density (MVD), mast cell density (MCD), and ganglionic cell count and measurements. The mean number of CD34-positive microvessels in microscopic fields, the MVD, had a value of 83 for the upper parts, and 82.7 for the lower parts of SCSGs. The mean number of tryptase-positive mast cells in microscopic fields, the MCD, was 4.5 in the proximal parts, and 4.7 in the distal parts of SCSGs. The mean number of ganglionic neurons in microscopic fields was 19.5 in the proximal parts, and 19.8 in the distal parts of SCSGs. The density of CD34-positive microvessels, the density of tryptase-positive mast cells, and the density, mean diameters and mean areas of ganglionic neurons were not significantly different in two observed parts, upper and lower of the SCSGs. In conclusion, the distributions of microvessels, mast cells, and neurons in two parts of the SCSGs were uniform with no specific micromorphological variations, there is a homogenous vascular and cellular pattern within the SCSGs.
