A STUDY ON THE LAMINOARCHITECTURE OF THE LUMBOSCRAL AND CAUDAL PORTIONS OF THE SPINAL CORD GRAY MATTER IN THE DAIRY CATTLE

摘要: 本研究取８头初生黑白花奶牛的腰荐尾段脊髓，分节后横切成３ｍｍ厚的脊髓块。其中７例在切片剪用苯胺蓝或尼氏混合液的块染法作细胞染色；１例用Ｗｅｉｌ氏法作髓鞘染色。均作石蜡切片。结果表明：奶牛腰荐尾段脊髓灰质基本上象猫那样分为１０个板层，但在层的范围，形态，结构等方面也有自己的特点。本文还与其它一些动物和人的脊髓灰质板层构筑进行了比较。

Abstract: The Lumbosacral and caudal portions of spinal cords from 8 new -born black and white dairy cattle were cut transversely into pieces of 3 mm thickness after being divided into segments. The spinal cord pieces from 7 of the animals were stained with toluidine blue or with Nissl mixture for cell bodies before sectioning. The spinal cord sections from 1 of the animals were stained by Weil's method for myelin sheaths. All spinal cord were cut transversely by paraffin sectioning. It was found that the spinal cord gray matter of the lumbosacral and caudal portions in the dairy cattle could be divided basically into ten laminae as in the cat. However, differences were observed in some of the detailed features. The laminoarchitectures of the spinal cord gray matter of the dairy cattle and other animals including man are also compared in this paper.
