The effects of a long-term action of organophosphate compound - dichlorvos (DDVP)
on the acid and alkaline phosphatase activities in Drosophila melanogaster was studied. DDVP
is among the most widely used chemicals in agriculture in the world. Examined enzymes:
alkaline phosphatase and acid phosphatase were extracted from several generations of
DDVP-treated strains of Drosophila melanogaster....
Pesticides are widely used in agriculture, food production and household. Due to the
broad spectrum of their activity, their biological action is extensively investigated. We
assessed the genotoxidty of methylparaoxon - the main metabolite of commonly used
organophosphorus insecticide, methylparathion. Freshly isolated human peripheral blood
lymphocytes were incubated for 1 h with methylparaoxon...
P-selectin is stored in the a granules of blood platelets. Following platelet activation by
different agonists, P-selectin is expressed on the cell surface where it mediates adhesion
primarily to leucocytes.The aim of the study was to evaluate the direct effect of Proteus
mirabilis lipopolysaccharides on the P-selectin expression on the platelet surface measured by
cytometric method. The obtained...
