Abstract:
OBJECTIVETo document morphological changes in hepatic microcirculation in liver tissue with hepatitis B and the pathogenesis of hepatic microcirculatory disturbances.
METHODSLiver tissue samples were obtained from patients with hepatitis B by liver biopsy. These samples were examined with a light microscope and transmission electron microscope.
RESULTSHepatic microcirculatory disturbances existed in patients with hepatitis B, including those with normal liver function, manifested by red blood cell aggregation in sinusoids seen under light microscope and sinusoidal capillarization seen under electron microscope. Weibel-Palade bodies in sinusoidal endothelial cells were seen in 26 out of 53 cases. Intimate contacts were found between lymphocyte/Kupffer cells and sinusoidal endothelial cells.
CONCLUSIONSHepatic microcirculatory disturbances exist in patients with hepatitis B. The appearance of Weibel-Palade bodies in sinusoidal endothelial cells may be a key step in the development of hepatic microcirculatory disturbances.
