title: [Histochemical and cytologic changes in the liver in experimental poisoning and subsequent pregnancy].
abstract: In 275 white rats chronic intoxication was produced by injection of amidopyrine acetaldehyde and chloraldehyde derivatives for 4 months. Histochemical and electron microscopic investigations of the liver under the experimental conditions and subsequent pregnancy revealed certain changes in nucleic metabolism, glycogenolisis, in the content of sulfhydryl, disulfide, carboxylic groups of protein molecules. Decrease in activity of enzymes of Krebs cycle and pentosophosphate cycle proved the deep changes in hepatocytes at the level of oxidation-reduction processes and protein synthesis. Ultramicroscopic changes in the nucleus, in cytoplasmic network, mitochondria and local degenerative alterations determined the level of morphologic reconstructions in connection with the intoxication. As the liver performs a number of vital functions and is closely connected with regulatory systems of the organism, morphofunctional shifts in the organ affect unfavourably the system mother--fetus.
