1·ObjectiveTo observe the ionizing radiation effect on filamentous actin of vascular endothelial cell and explore its mechanism.

目的观察电离辐射对血管内皮细胞纤维肌动蛋白的影响，探讨血管内皮细胞电离辐射损伤的机制。

2·Filamentous actin was distributed in the cytoplasm near the cell periphery Department, arranged to go along the cell contour lines, while no actin distribution in the nucleus;

肌动蛋白呈丝状，分布于细胞质外围靠近细胞膜处，沿细胞轮廓排列走行，而在核周则无微丝分布；
