On the Existence within the Liver Cells of Channels which can be directly injected from the Blood-Vessels

In a series of papers dating from 1897, resumés of winch are given in the Bulletin international de I'académie des Sciences de Cracovie, Professor Browicz gives the results of observations on the liver cells, both in the normal state and in a pathologically altered condition, and draws from these observations certain important deductions. The most prominent fact which is recorded is the appearance (under normal conditions in the liver of the newborn child, and under pathological conditions in the adult human liver; under normal conditions, and after the intravenous injection of hæmoglobin some hours prior to death, in the liver of the dog) of erythrocytes, singly and in groups, and of free hæmoglobin and hæmoglobin crystals, as well as brown pigment, in the form both of granules and crystalline clumps, within the hepatic cells, both in the nucleus and in the cytoplasm. After affirming the undoubted existence of intracellular biliary passages communicating with intercellular bile ducts,—which intracellular passages he regards, not as accidental and temporary vacuoles, but as preformed channels within the cells, — Professor Browicz states that his observations, especially the presence within the liver cells of erythrocytes, demonstrate that the cells must be in communication with the hepatic capillaries.
