查询词典 occlusion

Focal ischemia induced by photochemically thrombotic distal middle cerebral artery occlusion model to adult rats results in necrosis at the infarct core and activation of complex signal pathways for cell death and cell survival in the penumbra.

本实验室前期工作初步证明ghrelin可保护谷氨酸及脂多糖诱导的原代培养大鼠脑皮质神经元的损伤，也能减少线栓大脑中动脉引起的脑梗塞体积，说明ghrelin对脑缺血引起的神经元损伤具有一定的神经保护作用，有可能成为一个内源性神经保护多肽，具有重要的理论价值和实践意义，值得深入研究。

结果 涂层界面形貌的不同反映出两种涂层的结合机理不尽相同，冷喷涂层界面出现明显的机械咬合现象，而轧制涂层以冶金结合为主；冷喷涂层组织致密，孔隙率随着喷涂厚度的增加逐渐降低；冷喷涂层的表面粗糙度高于轧制覆铜板，有必要对其进行一道轧制处理，改善涂层表面平整度。

This operation is suitable for the following portal hypertension: simple occlusion of hepatic vein (a pathological type of Budd-Chiari syndrome)thrombosis in portal vein or prehepatic portal hypertension due to cavernous transformation; intrahepatic portal hypertension with rebleeding after treatment of splenectomy or without operation, and the patients with liver function in Child A or B class.

本手术主要适应于以下原因引起的门静脉高压：①单纯化肝静脉闭塞(布-加综合征的一种病理类型)；②门静脉主干血栓形成成海绵样变性引起的肝前性门静脉高压；③肝内型门静脉高压行断流术后再发出血或未行手术，肝功能为Child A和B级者。
