Vascular endothelial growth factor (VEGF) induces proliferation of endothelial cells, stimulates angiogenesis, and increases vascular permeability, but information about its role in periodontal diseases is limited. The aim of this study is to determine the association between VEGF expression in healthy and periodontally diseased tissues of healthy and diabetic patients.
Seventeen systemically healthy and 17 Type 2 diabetic patients (DM), all diagnosed with periodontitis were enrolled into the study. Gingival samples were collected from both periodontal and healthy sites in all patients. Each patient served as his/her own control samples were subjected to immunohistochemical analysis.
The diseased sites of diabetic subjects expressed higher level of VEGF when compared to diseased sites of non diabetic subjects with chronic periodontitis, VEGF was observed in healthy periodontal tissues of both diabetic and systemically healthy people with periodontitis and VEGF was intensely present in monocytes and macrophages.
The increased expression of VEGF in diseased sites of diabetic patients suggests that diabetes mellitus might have direct influence over VEGF expression.
血管内皮生长因子(VEGF)可诱导内皮细胞增殖,刺激血管生成,并增加血管通透性,但关于其在牙周疾病中的作用的信息有限。本研究的目的是确定健康患者和糖尿病患者健康及牙周患病组织中VEGF表达之间的关联。
17名全身健康和17名2型糖尿病患者(DM)均被诊断为牙周炎,纳入本研究。从所有患者的牙周病变部位和健康部位采集牙龈样本。每位患者作为自己的对照,样本进行免疫组织化学分析。
与患有慢性牙周炎的非糖尿病受试者的患病部位相比,糖尿病受试者的患病部位VEGF表达水平更高。在患有牙周炎的糖尿病患者和全身健康患者的健康牙周组织中均观察到VEGF,且VEGF在单核细胞和巨噬细胞中大量存在。
糖尿病患者患病部位VEGF表达增加表明糖尿病可能对VEGF表达有直接影响。
