[The populational structure of peripheral lymphocytes in patients in the acute phase of opisthorchiasis].

The lymphocytic populations of the immune system were studied in patients diagnosed as having acute opisthorchiasis before and 1-3 days after treatment with biltricide in a dose of 60 mg/kg body weight. The acute phase of opisthorchiasis is characterized by the activation of B lymphocytes and immunological cellular reserve, by depressed T-lymphocytic population with a decreased helper inductor and suppressive killer potential. Three days after dehelminthization, there was a trend for immunoregulatory T cells to become normal. The high levels of B lymphocytes and zero cells were preserved.
