| 摘 要： | 目的观察血管内皮细胞生长因子 (VEGF)在烧伤创面肉芽组织和烧伤后不同时期增生性瘢痕中的动态变化 ,探讨VEGF在烧伤创面修复过程中的表达规律及其作用。方法选择临床手术切除的新鲜烧伤创面肉芽及各个时期的增生性瘢痕 ,制成匀浆液 ,应用ELISA方法检测匀浆液中VEGF的变化。结果VEGF可在烧伤创面肉芽组织中有一定的表达 ,随着增生性瘢痕的发展 ,其表达量进一步增加 ,在 4— 6个月的增生性瘢痕中 ,表达量达到峰值。瘢痕成熟后 ,VEGF的组织表达逐渐下降。结论VEGF的表达量与增生性瘢痕组织中的血管丰富程度以及成熟程度密切相关 |

| Abstract: | ObjectiveTo explore the role of vascular endothelial growth factor(VEGF) in the growth and development of hypertrophic scar.MethodsThe burn wound samples of various stages were selected from transition of wound granulation tissue to scar and in long-persisting post-burn hypertrophic scar, and the concentrations of VEGF protein were detected using enzyme-linked immunosorbent essay (ELISA) method. ResultsThe tissue homogenate concentration of VEGF protein increases gradually from the wound granulation tissue to hypertrophic scar before it achieves summit concentration during 4 to 6 month. The concentration of VEGF degreases gradually after the maturation of hypertrophic scar. The high concentration of VEGF is synonymous with the large amount of capillary of the immature scar.ConclusionsThe abnormal expression of VEGF is related to the growth and development of hypertrophic scar and induces excessive and uncontrollable angiogenesis. |
| Keywords: | hypertrophic scar vascular endothelia growth factor(VEGF) tissue homogenate expression |
