CHEMICAL ELEMENTS IN FASCIOLA HEPATICA (TREMATODA) AFTER DIETHYLNITROSAMINE TREATMENT

The aim of the work was to be investigated the trace elements content in Fasciola hepatica under the toxic effect of diethylnitrosamine (DENA). The study of the trace elements in the injured from DENA helminthes showed specifically changed picture. The levels of Zn and Fe were heavily decreased but Rb – slightly reduced. The contents of Cu, Co, Br, Mo and Se were similar to those of the intact helminthes. The content of Cr was increased. We supposed that the morphological changes of F. hepatica on the background of DENA intoxication lead to a mineral imbalance related to the pathophysiology of the helminthes.
