選用體重約為1000公克之家兔6隻,作脊髓灰質細胞結構之研究。將所有脊髓成連續橫斷切片,並用焦油紫(cresyl violet)染色。在顯微鏡觀察下,根據神經細胞之大小、形狀、分佈密度以及排列情形,並參照Rexed氏之積層命名法,結果可將家兔脊髓灰質清楚地區分為9個細胞層。其中第Ⅰ層至第Ⅴ層偏佈於背柱內,各層較狹窄,其排列方向,淺層者大致與脊柱之背面曲度相符合,深層者漸顯平直,橫越脊柱。第Ⅵ層僅見於C1至T3及L3至S4之各髓節,但自S1以下者,逐漸縮小,同時移向內側部位。至於第Ⅶ及第Ⅷ兩層,厚度大增、佔據腹柱之絕大部分區域。第Ⅸ層則往往分散為2至7群大小不同之細胞區,而且大多散佈於第Ⅶ或第Ⅷ層之外側或腹側邊區。另外還有一個細胞區,圍繞在灰質中央管(central canal)周圍者,特別列為第Ⅹ細胞層。這些細胞層大部分都由脊髓之起端一直延伸達於末端,但是隨著通過不同髓節時,各細胞積層之分佈範圍與相互關係位置,都有特異之移行變化,可資識別。
The cytoarchitectural organization of the spinal gray matter in 6 rabbits about 1000gm in average weight has been investigated. All the spinal segments were sectioned serially at a cross plane and stained with cresyl violet. Based on the microscopies of the rabbit segmental serials, and according to the size, Shape, density and the arranging pattern of its nerve cells, We have found that the spinal gray matter in the rabbit can be divided into 9 cell-layers by means of Rexed's method reported in 1952, and these layers were arranged and named from dorsal to ventral side as laminae Ⅰ, Ⅱ,…… etc. The first five layers were included in the dorsal column, and each of them was somewhat narrower than anyone elsewhere. The long axes of the cells in the superficial layers Were roughly corresponding to the dorsal surface of the dorsal column, but that of the deeper layers were gradually appeared straight, and extending directly across near the base of the dorsal column. Lamina Ⅵ existed only in C1 to T3 and L3 to S4 segments, but bellow the level of S1 was gradually to reduce to nothing, meanwhile, it migrated to the medial part of that side. As for laminae Ⅶ and Ⅷ, their thicknesses were greatly increased and nearly occupied most of the ventral column. Lamina Ⅸ was usually grouped into 2 to 7 various sized columns of motor nuclei, and strewed in the lateral or ventral area of laminae Ⅶ and Ⅷ. There is another cell area, named lamina Ⅹ, setting around the central canal. On the whole, most of these cell layers begin at the cranial end of the cord and run through it toward the caudal end. But on their arrivals at the different levels of the cord, the ranges and relations of the distribution of these laminated cell layers, have made some special migrating changes which may be identified.
