近年来,一些学者重视研究各种疾病时心肌中小冠状动脉的病损。本文对149例尸检心脏切片标本做了组织学观察,探讨小冠状动脉增生性病损的意义。材料与方法收集心脏性猝死尸检35例,又无选择地连续观察尸检心脏标本114例,共计149例。常规从左、右心室游离壁各取一块包括各层的心肌组织,有的还自室间隔切取一块标本。全部标本均用10%福尔马林液固定,石蜡切片,HE染色,光镜观察。在此基础上,再挑选有和没有小冠状动脉增生性病损的各5例,每例选一个组织做连续切片,每隔10片染一片,进行系列观
In recent years, some scholars have paid great attention to study the lesion of small and medium coronary arteries in various diseases. In this paper, 149 cases of autopsy heart biopsy specimens made histological observation, to explore the significance of small coronary artery lesions. Materials and Methods 35 cases of sudden cardiac death were collected, and 114 cases of autopsy heart samples were continuously observed with no choice. Conventional left and right ventricular free wall each take a piece of heart muscle tissue, including layers, and some also cut off from the ventricular septum a specimen. All specimens were fixed with 10% formalin, paraffin sections, HE staining, light microscopy. On this basis, and then pick with and without small coronary proliferative lesions of the 5 cases, each case choose a tissue to do continuous sections, every 10 dyed a series of observations
