Abstract
|

|
This study was designed to observe the ultrastructural characteristics of hepatocytes, endothelial cells, Kupffer cells and Ito cells in the liver of Suncus Murinus. The specimens were processed for electron microscopy, following the immersing in the Karnovsky fixative for 8 hrs and 1% osmium tetroxide for 2 hrs. Hepatocytes contained large number of lipid droplets and large mitochondria. Spaces between the hepatocytes were narrow and in some area were irregular in contours with long and slender microvilli of the hepatocytes. Endothelial cells may contain lysosomes as Kupffer cells do. Bile canaliculi were relatively wide and easily seen in the lobule. Bile ductules located in the space of Disse were formed by the hepatocytes and small cells with or without lipid droplets. The results suggest that the Suncus Murinus liver shows some ultrastructural characteristics of aquatic animal livers, endothelial and Kupffer cells may be the same one only in the different functional states, and the bile ductule may be partly formed by the Ito cell.
