摘　　要：采用CD34抗体标记正畸牙周组织的血管内皮细胞,探讨He-Ne激光照射对兔正畸牙周组织血管改建的影响。35只大耳白兔随机分未加力组及加力组,对实验标本进行CD34免疫组化染色,用计算机图像分析系统测定正畸牙周组织的微血管密度(MVD)与微血管面积(MVA),应用SPSS统计软件进行统计学分析。经He-Ne激光照射侧的微血管密度与微血管面积均普遍大于对照侧。除加力1d组外,其余各加力组照射侧与对照侧之间的微血管密度、微血管面积的差异均有统计学意义(P<0.05,P<0.01)。Applying the antibody of CD34 stained the vascular endothelial cell of periodontal tissue and investigated the effects of He-Ne laser irradiation on the blood vessel remodeling (BVR) of orthodontic periodontal tissue in rabbit. 35 rabbits were divided into normal group and experimental group randomly. All of the tissue sections proceeded with CD34 immunohistochemical staining, measured the microvessel density (MVD) the microvessel area (MVA) of periodontal tissue by computer image analyzing system using SPSS software to proceed with statistic test. MVD and MVA received He-Ne laser irradiation were higher than those of the control side. The differences of MVD, MVA between the irradiated and control side in every experimental group were all significant (P < 0. 05, P < 0. 01), except for the 1st day group.
