[Accumulation of some toxic microelements in liver tissue and helminthes obtained from patients with Opisthorhis felineus (Rivolta, 1884) and Metorchis bilis (Braun, 1890) invasion].

According to some available reports, it is known that there may be an increased accumulation of some micronutrients in the samples of hair and blood. The purpose of the present investigation was to study the general regularities of accumulation of micronutrients in the samples of liver tissue and helminthic bodies obtained from patients with opisthorchiasis who lived in Tomsk and who had different etiological types of Opisthorchis (O. felineus) and Metorchis (M. bilis). The fact that M. bilis helminthes were present in 15 of 22 liver samples was verified by polymerase chain reaction. As compared with healthy individuals, patients with Opisthorchis invasion (particularly those with mixed Opisthorchis and Metorchis invasion) were found to have an increased liver tissue accumulation of chromium, mercury, cesium, lanthanum, and cobalt.
