[Ultrastructure of liver cells of shrews]

It was established that the hepatocytes of least shrew (Sorex minutissimus) contained 1-2 nucleus with wide nuclear pores and big nucleolus. There are abundant mitochondria with numerous crists in their matrix (many organelles were divided along the crists). Each mitochondrion was surrounded by the cistern of granular endoplasmic reticulum. The ultrastructure of Golgi complex (1-2 flat cisterns, small vesicles] indicated that the bile was secreted often, by small portions, that was the adaptation to repeated fractional feeding. There were many peroxisomes in the cytoplasm of hepatocytes. Lipid droplets were absent, glycogen granules were not at all hepatocytes. Sinusoidal cells had the usual structure. All sinusoids were open and consisted of the erythrocytes, fragments of hepatocyte cytoplasm and myelin figures in its lumen.
