74 ABSTRACT Title of thesis Evaluation of antiprotozoal activity by Tetrahymena pyriformis Charles University in Prague Faculty of Pharmacy in Hradec Kralove Department of Pharmaceutical Botany and Ecology Candidate: Daniela Osecká Consultant: Mgr. Jitka Vytlačilová The protozoal pathogens are causing asymptomatic and symptomatic infections. The risk of the disease threatens to almost every man, therefore it is very important the antiprotozoal therapy. Tetrahymena pyriformis is a unicellular organism, which we tested out under the action of three substances, albendazole, mebendazole and ornidazole. We used two methods applied to measuring the viability of protozoan. It is a basic method for testing the inhibition of growth of the organism Protoxkit FTM using the conversion of food biomass in suspension of infusorian and MTT method, which uses the reduction of MTT dye (3 - [4,5-dimethyl-thiazol-2-yl] -2,5-diphenyl-tetrazolium bromide). Spectrophotometrically from the measured data, we build tables and charts, optical density, depending on the time of culture and calculated percent inhibition for five descending concentrations of test substance. Our aim was to determine whether all the test substances showing the antiprotozoal activity. The greatest toxicity showed albendazole (method Protoxkit FTM at the...
