The study aims to clarify the influence of experimental cholestasis mother on the structure of the liver of young rats in early postnatal development (Day 2) and to explore the possibility of the correction of these disturbances with Ursofalk drug. Material was obtained from 30 outbred albino rat pups and studied using histological, histochemical, morphometric and electron microscopic methods. It was found that under the influence of maternal cholestasis, the liver of the offspring demonstrated the dilation of sinusoidal capillaries, the decreased activity of succinate dehydrogenase and increased activity of NADH dehydrogenase in hepatocyte cytoplasm, the development of significant ultrastructural abnormalities (disappearance of lipid droplets, accentuated heterogeneity of mitochondrial size and shape, increased number of lysosomes). The application of Ursofalk partially restored hepatocyte structure and metabolism.
