The results showed that they were surrounded by capsules and composed of cortexes and medullas. The cortex was made up of lymphatic nodule, internodular diffuse lymphatic tissue, paracortical area and cortical sinus; 结果表明:淋巴结外包被膜,实质由皮质和髓质构成,皮质又分为淋巴小结、小结间弥散淋巴组织、副皮质区和皮质淋巴窦;
Conclusion: The decrease of apoptotic cells in the internodular and deep cortex indicate that low dose radiation may suppress the apoptosis of T lymphocytes and play a role in immune regulation. 结论:低剂量辐射所致的小结间区及深皮质区凋亡细胞数减少,是低水平辐射兴奋效应的一种表现。
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. 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。
