Modulative influence of lysozyme dimer on defence mechanisms in the carp (Cyprinus carpio) and European sheatfish (Silurus glanis) after suppression induced by herbicide Roundup.
Immunomodulation is a commonly used method of prophylaxis in humans and animals. Lysozyme dimer (KLP-602) was used at a dose of 50 ug/kg b.w. in order to correct the immunosuppression caused by the action of herbicide glyphosate (Roundup- Monsanto), which was used in a single bath for 10 minutes in a concentration of 100 mg/l of water. The investigations were carried out on 2 species of fish: the carp (Cyprinus carpio L.) and european catfish (Silurus glanis L.). Herbicide glyphosate caused a decrease in metabolic and phagocytic activity (RBA and PKA) and in proliferative response stimulated by Con A and LPS in carp and european catfish. The immunosuppression sustained for about 2 weeks. The results obtained indicate the possibility of correction of immunosuppression applying lysozyme dimmer (KLP-602) after use of which, the level of the studied indexes increased.
