In this article 4 cases of spinal subarachnoid hemorrhage were reported and the etiology, clinical manifestations, diagnosis and treatment were discussed. Spinal hemangioma was considered the most common cause of the disease. One of the four cases was demonstrated to have spinal hemangioma during operation and another case was diagnosed as spinal vascular anomaly by spinal myelography. It is indicated that rapid onset, irritation of spinal roots occuring before headache, soon followed by manifestation...

In this article 4 cases of spinal subarachnoid hemorrhage were reported and the etiology, clinical manifestations, diagnosis and treatment were discussed. Spinal hemangioma was considered the most common cause of the disease. One of the four cases was demonstrated to have spinal hemangioma during operation and another case was diagnosed as spinal vascular anomaly by spinal myelography. It is indicated that rapid onset, irritation of spinal roots occuring before headache, soon followed by manifestation of damage of the spinal cord without brain involvement are the characteristics of spinal subarachnoid hemorrhage. Recurrences are not uncommon. It is advisable to do further examinations to find out the underlying cause before diagnosis.

本文报告4例脊髓蛛网膜下腔出血,并结合文献讨论了病因、临床表现、诊断及治疗等一般特点。认为脊髓蛛网膜下腔出血最常见的原因是脊髓血管瘤,4例中1例经手术证实为脊髓血管瘤,1例经脊髓造影诊断脊髓血管畸形。急性起病,在头痛前就出现明显的脊神经根刺激征,并很快出现脊髓损害症状,无明显脑症状,是脊髓蛛网膜下腔出血的特征。本病也有复发。并指出在确诊前应作进一步检查,尽可能明确其病因。

After severance the ventral spinal roots in 10 dogs, the distribution of the anterograde degeneration was studied by means of Nauta's technique with the following conclusions:

切断10只狗的脊神经前根(作对照的有:行后根切断术的;交感干切除的;及只作椎板切开暴露脊髓和脊神经根而不切断的),用Nauta氏法和山鸟氏法追踪了在中枢变性纤维及终末前变性纤维的分布,得到了如下的结果: 1.切断前根后,在脊髓和延髓中规律地出现变性纤维,这证明有从前根进入中枢的传入纤维。2.变性纤维在脊髓后索上行,亦有在灰质中上行者。至手术节段以上的胸、颈段后柱灰质中均有上行终支或侧支的终末前及终末变性纤维。3.在廷髓薄束核非簇团细胞周围及薄束核之网状区,也发现终末前及终末变性纤维。4.前根传入变性纤维多数位于手术侧,脊髓节段越高,变性纤维越少。5.前根传入纤维的分布与后根传人者有很大区别:(1)前根传入纤维从本节段灰质起,即有靠灰质内侧分布的“向内趋势”,以及它们插入薄束中间而上行。后根切断对照组中的后根传入纤维在后柱灰质呈“均匀趋势”分布,进入薄束“外加”方式;(2)前根传入纤维向对侧的投射,显然多于后根传入纤维;(3)前根传入纤维在脊髓内有远节段(超过4个节段以上)投射也是一个特点。

Spinal ventral roots of 10 infants were examined. Eight pairs of spinal ventral roots were cut off from 10 infant cadavers including the following segments: C_6, C_7,T_5, T_(11), L_3, L_5, S_1, and S_2. Serial longitudenal sections were prepared and stained with Niss's method. The presence of sensory neurons were recorded and their num- ber were counted. The results were as follows:Nerve cells in the spinal ventral roots were found in all the cases examined.The minimal number was 58 cells in No. 8, and the maximal...

Spinal ventral roots of 10 infants were examined. Eight pairs of spinal ventral roots were cut off from 10 infant cadavers including the following segments: C_6, C_7,T_5, T_(11), L_3, L_5, S_1, and S_2. Serial longitudenal sections were prepared and stained with Niss's method. The presence of sensory neurons were recorded and their num- ber were counted. The results were as follows:Nerve cells in the spinal ventral roots were found in all the cases examined.The minimal number was 58 cells in No. 8, and the maximal number was 203 in No. 10. There were altogether 1,446 cells found in 117 spinal roots, and no cell in 35 roots. The highest number of nerve cells observed in a single root was 83.The nerve cells were scattered all over the spinal ventral root from its attachment to the spinal cord to its junction with the dorsal root. More cells were found in its distal extremity close to the spinal ganglion. They appeared singly, in groups of two or three, or in a cluster looking like a small ganglion. They were usually distributed among the nerve fibers, or around the blood vessels, or beneath the epineurium of the ventral root. They were ovoid in shape, with the long axis paralleling the course of nerve fibers. Nuclei were round in shape, Nissl granules were evenly distributed in the cytoplasm. They were different in sizes, ranging from 15 to 60 μm. There were 808 cells (56%) more than 30~50 μm. 607 cells (42%) less than 30 μm, which accounted 98% of the total cell population.

本文报道在10具婴儿尸体的117条脊神经前根中,见到神经细胞1446个。其中大多数前根中含有一定数量的神经细胞。神经细胞弥散地分布于前根各处,以邻近脊神经节的前根远侧端较多,且多数以单个形式出现,也有2~3个成群排列的,偶尔还见有小神经节状的细胞集团。前根细胞的大小、形态、尼氏物质的分布,具有完整的卫星细胞包被等特点,皆类似于脊神经节细胞。两者可能属于同一范畴。就前根细胞出现的可能和意义及其来源进行了讨论。
