心肌的间质网络结构对心脏的收缩和舒张起着很重要的作用。近年来引起许多学者的关注 ,目前有关心肌间质网络的电镜报导甚少 ,本实验对犬心脏心肌间质网络关系的研究提供超微形态学基础。材料与方法取成年犬的左心室的心肌组织 ,分别横切与纵切成组织块 ,戊二醛 4℃固定 2 4h,?
Myocardial interstitial network structure of the heart contraction and relaxation plays a very important role. In recent years, many scholars have aroused the attention. At present, there are few reports on the electron microscopy of myocardial interstitial network. This experiment provides the basis of ultrastructural morphological study on the myocardial interstitial network in dogs. Materials and Methods The myocardial tissues of left ventricle of adult dogs were cut and cut longitudinally into sections of tissue, fixed with glutaraldehyde at 4 ℃ for 24 hours.
