Computer assisted quantitation of terminal hepatic vein connective tissue in the rat.
Computer assisted image analysis has been used to quantify the cellular and extracellular connective tissue component of rat liver terminal hepatic venules, in control animals and those exposed to 40% ethanol in drinking water. A significant relationship existed between the size of the terminal hepatic venule and the amount of connective tissue it contained in 14 of 15 controls and 17 of 18 ethanol exposed rats. Thickening of the terminal hepatic vein wall assessed to be present in ethanol treated rats by direct observation was confirmed by image analysis in all cases (p < 0.01). Significant differences between treated and control livers (p < 0.05) were detected by image analysis when not apparent to human observers. Sensitive quantitative assessment of terminal hepatic vein wall thickening was thus achieved by computerized analysis of liver sections.
