[Morphological criteria of chronic opisthorchiasis treatment].

Morphological examinations of the liver in chronic opisthorchiasis have both diagnostic and prognostic importance. Significant lowering of the number of cells of the portal tract inflammatory infiltrate per area unit (1 mmI), decreased number of neutrophilic and eosinophilic leukocytes, elevated count of monocytes are not only morphological markers of successful dehelminthization but they also reflect objective improvement of the liver state this being an absolute criterion of effective therapy.
