血管内皮生长因子（ＶＥＧＦ）又叫血管渗透因子，是一种特异地作用于内皮细胞的多功能因子，对诱导和调节肿瘤血管形成有重要作用。我们用酶联免疫吸附法检测了１１５例消化系肿瘤患者血清中ＶＥＧＦ的水平，旨在探讨ＶＥＧＦ在不同类型消化系肿瘤中的血清学水平和手术前后患
Vascular endothelial growth factor (VEGF), also known as vascular permeability factor, is a multifunctional factor that specifically acts on endothelial cells and plays an important role in inducing and regulating tumor angiogenesis. We used enzyme-linked immunosorbent assay to detect the serum VEGF levels in 115 patients with digestive system tumors, in order to investigate the serum levels of VEGF in different types of digestive tumors and before and after surgery
