Computerized morphometry of liver cells in diffuse hepatic diseases.

Computerized morphometrical measurements were made of liver cells and their nuclei taken from livers of healthy persons and from patients with acute hepatitis (AH), chronic hepatitis (CH), and liver cirrhosis (LC). Liver biopsies were performed on 127 people (24 convalescing from acute hepatitis, 20 with chronic inactive hepatitis (CIH), 24 with chronic active hepatitis (CAH), 38 with liver cirrhosis (LC) and 21 who were healthy controls (HC]. The specimens were stained with hematoxylin-eosin, then light microscopic pictures were obtained. The original cells were magnified 1000 times. The sizes of the cells and of their nuclei were calculated using a computer. Correlative variation was noted in cell and nuclear sizes resulting in an consistently constant nucleus-cytoplasm ratio. Average sizes of both cells and nuclei were maximal in livers with LC, followed in decreasing order by those in livers with CAH, CIH, HC and convalescent AH. The smallest cells and nuclei were found in convalescent AH cases. It might be possible to some degree to obtain gross impressions of the histopathological type of the liver lesion by measuring the sizes of cells and nuclei of the liver.
