Interaction of immunomodulant substances in mouse experiments with special regard to drug sensitivity and bacterial translocation.
In acute toxicity experiments changes in drug sensitivity and in the rate of bacterial translocation (BT) were investigated in mice treated with immunomodulatory drugs: dianhydrogalactitol (DAG) in doses 20 and 30 mg/kg, chlorpromazine (CPZ) in doses 60 and 75 mg/kg and Mannozym (M) in dose equivalent to 40 mg per kg zymosan. The drugs were used separately or in combination. The sensitivity of mice to immunosuppressive DAG or CPZ was higher in the case of combined treatment than that of separately treated ones. The rate of BT was also higher in mice receiving combined treatment. Pretreatment with M exerting an immunostimulatory effect, influenced neither the sensitivity of mice to DAG or CPZ nor the very low normal rate of BT. The present results reinforced the authors' earlier observations that the effects of immunosuppressive drugs cumulated in and caused more serious damage of the organism. The increase in drug sensitivity to immunosuppressive agents may be connected with an increased rate of BT and effect of endotoxin.
