髓索

MDS的诊断以髓索中央出现ALIP更确诊。

When the ALIP is appeared in medullary cord , the diagnosis of MDS is more sure .

髓质又分为髓索和髓质淋巴窦。

The medulla was divided into medullary cord and medullary sinus .

髓索浆细胞丰富，Ig强阳性。

In the medullary cord , plasma cells were often present in great number , with Ig strongly positive .

皮质浅层的小结间区内偶见阳性纤维分布，淋巴小结内未发现阳性纤维。髓索和皮质深层淋巴组织中走行的含NPY神经纤维与免疫细胞关系密切。

A positive fiber was occasionally seen in the internodular region , and nodular regions were free from nerve fibers , NPY-containing nerve fibers in the lymphoid parenchyma of the medullary cord and deep cortex travelled in close association with immunocompetent cells .

结果：①3例脊髓亚急性联合变性患者脊髓MRI的特点：病例1中下胸髓后索区对称性长T2高信号；

RESULTS : ① MRI features of SCD patients : For case 1 , there was symmetrical long T2 high signal in the posterior funiculus of middle and lower chest marrow ;

方法将大鼠颈曲由下突位变为上突位，在手术显微镜下切开C3、C4间的黄韧带，横断颈髓外侧索；

Methods After the thoracic curve was changed from inferior to superior , the yellow ligment between C3 and C4 and the lateral funiculus were transected under the operating microscope ;

白髓中未见明显的脾小结、淋巴鞘结构，红髓由脾索和脾窦构成。

The red pulp is composed of splenic cord and splenic sinus .

第30天，脾白髓与淋巴结皮质淋巴组织萎缩，淋巴结皮质基质细胞增多，髓索浆细胞大量增多等慢性炎症现象发生。

On the thirtieth day , chronic inflammation occurred , including white pulp of spleen and lymphoid tissue of cortex lymph node atrophy , stromal cells of cortex of lymph node being in a large numder and plasma cells of medullary cord increasing largely .

脾脏白髓的脾小体和中央动脉淋巴套增生，淋巴细胞增多，红髓的脾窦和髓索轻度充血；

The small ball of white marrow of spleen and the surface of lymph of the central artery proliferated and red marrow spleen hole and marrow cable bleeded .
