Suppression of immune response associated with functions of B-cells, Th1- and Th2-lymphocytes and interleukins produced by these cells, and pharmacological correction of these disturbances upon acute intoxication with methanol

Experiments on Wistar rats showed that acute poisoning with methanol (0.75 LD50) leads to the suppression of cellular and humoral immune responses and decreases the blood concentration of interleukins (IL-2, IL-4) with an increase in the IL-2/IL-4 ratio. These facts indicate that a decrease in Th2 lymphocyte activity is more pronounced in comparison to that of Th1 cells. The immunomodulators mielopide and polyoxidon administered in a daily dose of 10 mg/kg for 4 days upon acute poisoning with methanol virtually completely restore the cellular and humoral immune responses, the activity of natural killers, and the synthesis of interleukins.
