    Streszczenie angielskie: The study was aimed at detecting cellular sources of transcripts for two cytokines, TNF-ŕ and IL-1ŕ in infection with human cytomegalovirus (HCMV) or hepatitis B virus (HBV). The studies were performed on paraffin sections of organs (liver, pancreas, spleen, lungs) obtained upon autopsy from a child decreased due to acute inborn HCMV infectio on paraffin secions of liver biopsy, obtained from a child with HCMV-induced chronic hepatitis, and of liver biopsies obtained from children with chronic type B hepatitis (n = 13). The classical in situ hybridization was applied with digoxygenin-labeled probes and amplification by the ImmunoMax technique. In HCMV infection, the most pronounced expression of mRNA for TNF-ŕ and II-1ŕ was detected in pancreatic islets (mainly in á cells) and, then, in a decreasing sequence, in liver (in macrophages and sinusoidal endothelial cells) and in lungs (in alveolar macrophages). No expression of the two cytokines was detected in the sinusoidal endothelial cells) and in lungs (in alveolar macrophages). No expression of the two cytokines was detected in the spleen. In HBV infection, weak expression of TNF-ŕ in the liver were observed, mainly in sinusoidal endothelial cells and in mcrophages as well as in hepatocytes. These results were confirmed by immunocytochemical experiments.
