الوصف: To determine the morphological specifics of the stromal and parenchymal liver components of 6-12-months old children from HIV-mono-infected mothers. Materials and methods. The morphometric investigation included 87 liver tissue biopsies of 6-12-months old dead children from HIV-mono-infected mothers. All morphometric parameters of the parenchymal and stromal liver components were calculated using the Avtandilov`s microscopic morphometric grid, which was consisted of 100 equidistant points. It was inserted into the microscope`s ocular tube with a total × 200 microscope magnification. The number of points that were found on the corresponding types of parenchymal and stromal liver components was calculated. In every case, it was selected 10 random microscopic areas and then all data were obtained, calculated and presented as percentages. Results. Morphometric parameters of hepatocytes: mononuclear hepatocytes – 90.2±7.6 % [control – 93.5±7.1], two-nuclear hepatocytes – 9.8±1.2 % [control – 6.5±1.2], TMHC (two-/mononuclear hepatocytes coefficient) – 0.10±0.02 [control – 0.06±0.01], hepatocytes with fat vacuoles – 19.6±2.1 % [control – 0.5±0.2]. Parenchymal and stromal liver components: parenchyma – 56.1±3.3 % [control – 74.2±4.3], stroma (including blood vessels and bile ducts) – 43.9±3.7 % [control – 25.8±2.6], SPI (stroma/parenchyma index) – 0.78±0.02 [control – 0.34±0.01]. Morphometric parameters of all of the liver components: hepatocytes – 56.1±3.3 % [control – 74.2±4.3], portal tracts – 26.4±2.1 % [control – 3.1±0.6], central veins – 8.1±1.2 % [control – 9.3±1.4], sinusoids – 7.3±1.2 % [control – 10.5±1.3], bile ducts – 2.1±0.1 % [control – 2.9±0.2]. Expression level parameters: fibronectin – 73.2±4.2 % [control – 17.3±2.5], collagen type I – 15.9±1.2 % [control – 9.7±1.9], collagen type III – 20.1±2.6 % [control – 10.1±0.9], collagen type IV – 7.3±0.2 % [control – 5.9±0.2]. Conclusions. It was established, that in the liver of 6-12-months old children from HIV-mono-infected mothers, the parenchymal component of the liver showed the signs of its significant reduction, increase of regenerative activity of hepatocytes, and fatty degeneration of hepatocytes with a certain sign of reactive steatohepatitis. Also, it was established, that the stromal component of the liver of children from HIV-infected mothers showed the signs of its progressive proliferation and collagenization due to increased production and accumulation of fibronectin, type I, type III collagens in the stroma of portal tracts and newly formed septa, and the signs of hepatic sinusoid capillarization due to type IV collagen accumulation in the space of Disse of the hepatic sinusoids.
