目的对２４例正常成人肝小叶、门管小叶及肝腺泡等不同结构和功能单位进行形态计量测定。方法应用Ｑｕａｎｔｉｍｅｔ５７０Ｃ图像分析仪进行形态计量分析。结果测得正常肝小叶、门管小叶和肝腺泡的面积分别为１．４７２±０．２７３ｍｍ２、０．９１１±０．３０４ｍｍ２和０．６０２±０．１５８ｍｍ２；周长分别为４．２８９±１．０２２ｍｍ、４．１０６±０．９６４ｍｍ和３．２１８±０．５４８ｍｍ。肝小叶中央静脉偏位系数１．０４２±０．０３１；相邻门管小叶汇管区距离为０．８２１±０．２４８ｍｍ。结论本文为肝疾病的病理研究与诊断提供正常形态结构的客观参照指数。
Objective To measure the morphological characteristics of 24 adult normal hepatic lobules, portal leaflets and hepatic acinar in different structures and functional units. Methods Quantimet570C image analyzer for morphometric analysis. Results The area of normal hepatic lobules, portal leaflets and hepatic acinus were 1.472 ± 0.273mm2, 0.911 ± 0.304mm2 and 0.602 ± 0.158mm2, respectively, and the peripheral lengths were 4.289 ± 1.022mm, 4.106 ± 0.964mm and 3.218 ± 0.548mm. The central venous deviation coefficient of hepatic lobule was 1.042 ± 0.031, and the distance between adjacent portal venous portal area was 0.821 ± 0.248mm. Conclusion This article provides an objective reference index for the normal morphological structure of liver disease pathology research and diagnosis.
