Pathomorphology of fetal and mature liver under the lead intoxication and after the correction: the review of experimental data

Abstract

A-research concept and design; B-collection and/or assembly of data; C-data analysis and interpretation; D-writing the article; E-critical revision of the article; F-final approval of the article Lead is one of the most widespread pollutant which alters the mature liver and is especially harmful for the fetal liver. The typical alterations in the mature liver after the lead exposure are the hypertrophy and vacuolization of hepatocytes, circulatory disorders, mononuclear cellular infiltration. The morphological changes in the liver during prenatal development under the maternal lead treatment are inhibition of hematopoiesis, dystrophy of hepatocytes, disturbances in the liver architecture, its vessels and stroma with a gradient of pathological changes toward the peripheral parts of the organ. The manifestations of liver alteration after birth become deeper with age and develop to the necrosis, edema and inflammation. The biochemical disturbances in the liver are the decrease in the activity of enzyms of energy metabolism, inhibition of protein and nucleic acids synthesis, imbalance of the lipid peroxide oxidation system, and the increasing of oxidative stress with the further alteration of the membranes of the endothelium, red blood cells, hepatocytes, as well as mitochondrial membrane.
