In part one, we used HE staining to study effect of low power laser and to find out optimization wave length and power. 第一部分,利用HE染色研究弱激光治疗作用以及寻找最佳作用波长和功率。
HE staining: To prepare paraffin sections of placental tissue, observed them under high power lens of light microscope after HE staining, to evaluate the interstitial fibrosis and necrosis of villus and syncytiotrophoblast nodes. 2. HE染色法分析:制作胎盘组织石蜡切片,HE染色后于光镜下200倍视野观察绒毛间质纤维化、坏死及合体滋养细胞结节。
