The results of GUS staining showed that NPC2 expressed mainly in meristematic zone, elongation zone and vascular tissue of maturation zone of root tip; GUS染色显示NPC2在根中主要是在根尖分生区和伸长区表达,在成熟区主要是在维管组织中表达;
The anatomical structure of its primary vascular system was studied and its cotyledon node zone is longer than that of Ranonculaceae. 其初生维管系统的解剖学研究表明:子叶节区明显长于毛茛科植物幼苗,属顶枝伸长型。
Vascular compression to root entry zone of sensory root is the main cause of trigeminal neuralgia 感觉根入髓区血管压迫是三叉神经痛的主要病因
The intrahepatic vascular diseases played igniting and bridging roles in the development of LC. Through vascular inflammation-vascular obstruction-vascular proliferation and rebuilding-vascular fibrosis, fibrous zone was finally formed, causing disturbance of blood circulation of liver tissues, and leading to liver parenchyma denaturalization and necrosis. 在LC的发展中肝内血管病变起引爆和桥梁作用,通过血管炎症-血管阻塞-血管增生和改建-血管纤维化而最终形成纤维带,致肝组织血液循环障碍引发肝实质变性坏死。
However, as the result of the particularity of the arrangement of vascular bundle in the nodal zone, in some cases, the cutting forces, chip form and the quality of the machined surface would be different from the internodal zone. 但由于竹节部维管束排列方向的特殊性,在某些情况下,竹节部的切削力、切屑形态以及加工表面质量都和节间材有所差异。
A Preliminary Study on the Vascular Plant Flora of the Water-Level-Fluctuating Zone in the Three-Gorge Reservoir Area 三峡库区消涨带维管植物区系的初步研究
Conclusion The etiology of trigeminal neuralgia is that the unusual vascular oppress the root entry zone, and arachnoid membrane circling the nerve is thickened and sticked. To untie the arachnoid membrane and decompress the offending vascular is the effective methods in treating trigeminal neuralgia. 结论异常血管压迫三叉神经入根区,神经根周围蛛网膜增厚粘连是三叉神经痛的病因,行该区粘连的蛛网膜分离后,微血管减压是治疗三叉神经痛的有效方法。
The convertion of primary vascular system occurs in the Cotyledon Node Zone between root and stem. 观察幼苗的解剖学结构,发现根颈由子叶节区和下胚轴组成,初生维管系统在根和茎之间的转变发生在胚轴上很短的子叶节区。
Vascular compression was noticed in the root entry zone in 19 cases ( arterial in 16, venous in 3). 术中发现三叉神经出脑干处有血管压迫者19例(动脉血管压迫16例,静脉血管压迫3例)。
Morphological evolution and origin of the vascular plants viewed from the telome theory, stelar theory and cotyledon node zone theory 从顶枝学说、中柱学说和子叶节区学说看维管植物的形态演化和起源
Conclusion: The main cause of TN is the vascular compression of the root entry zone of nerve sensory root trigeminal. 结论:MVD手术的有效性证明了三叉神经感觉根入髓区血管压迫是TN的主要病因。
