The microscopic structures of the liver tissues from two amphibian species, T. vulgaris and T. karelinii, were studied by different histological staining techniques. The polyhedral shaped parenchymal cells of T. karelinii contain euchromatic mononuclei and dense cytoplasmic glycogen. These cells arranged as systematical cell cords in parenchyma. Pigment granules containing Kupffer cells (melanomacrophages) were found in the sinusoid wall. T. karelinii liver parenchyma have shown no clear lobulation and no concentrated reticular fiber network around the hepatocytes and vessels. The predominant glycosaminoglycan (GAG) type of T. karelinii was hyaluronic acid (HA), however, sulphated GAGs were almost absent. Hepatocytes from T. vulgaris were not polyhedral shaped, and contain euchromatic mononucleus. The glycogen content was not significant quantities in hepatocyte cytoplasm of T. vulgaris. These cells form radial arrangenment close to large vessels, however they found as cell clusters in bottom of parenchyma. Kupffer cells were found between the parenchymal cell groups and at the sinusoidal walls. These cells contain many pigment ganules in their cytoplasms. Reticular fibre networks were found between hepatocytes and vessels in lobulation lacking parenchyma. Around the hepatocytes and vessels, hyaluronic acid was the predominant GAG type.
