[Common intralobular microcirculatory module peculliarities in cholestasis in white rats].
The dynamics of intralobular microcirculatory module transformation in cholestasis was investigated. The liver tissues of 54 white Wistar rats were studied by Histology, TEM, TEM after injection of 1% Pb(NO(3))(3), vie common bile duct (CBD), SEM of corrosion casts prepared after methylmethacrylate injection vie CBD. It is demonstrated that liver is the basis of microcirculation of 4 different liquids: blood, bile, connective tissue liquid and lymph. Accordingly, in normal condition 4 different well formed compartments bordered from each-others by different types of cells exist. In the yearly stages of cholestasis (3-6 days) the function of bile drainage is partially overtaken by lymph pathways. This is accompanied by the beginning of the destruction of structures bordering above-mentioned microcirculatory beds. In the later stages of cholestasis (12-18 days) the final disorganization of microcirculatory compartments with mixture of all liquids is observed. It is accompanied by increased dystrophy of liver cells population.
