1·The microvessel density and vascular endothelial growth factor was measured in surgical specimen after immunohistochemical staining using anti-factor CD34, VEGF and compared to color pixel density.
对手术标本进行抗CD34因子及抗VEGF因子免疫组化染色，测量肿块微血管密度计数及血管内皮生长因子（VEGF）阳性表达率，与超声彩色像素密度值相比较。
2·If the specimen drips, particles are allowed to fall onto a layer of dry absorbent surgical cotton placed 300 mm below the specimen.
假如试片熔化，则滴下来的火焰分子会掉落在距试片下端300 mm处之棉花层。
