肝脏是机体的重要器官,其结构的研究早已为人们所注意。但由于光学显微镜分辨本领的限制,对肝脏有些微细结构如Disse氏间隙、窦周细胞、毛细胆管、核仁、内质纲等等的观察就很困难。自电子显微镜问世后,它被广泛应用于形态结构的研究如Fawcett(1955)、Richard(1960,1961,1963)、Aterman The liver is an important organ of the body, the structure of which has long been people’s attention. However, because of the limitations of optical microscopy, some of the liver microstructure such as Disse’s gap, sinus pericytes, bile ducts, nucleoli, endoplasmic reticulum and so on the observation is very difficult. Since the advent of electron microscopy, it has been widely used in morphological studies such as Fawcett (1955), Richard (1960, 1961, 1963), Aterman
