Charles University Faculty of Pharmacy Department of Biochemical Sciences Hradec Králové, Czech Republic Field: Patobiochemistry and xenobiochemistry Candidate: Mgr. Marie Urbánková Consultant: Ing. Barbora Szotáková, Ph.D. Title: The activity of biotransformation enzymes in mouflons with dicrocoeliosis and in healthy mouflons Abstract In vitro activities of cytochromes P450 (7-alkyl/aryloxyresorufin dealkyl(aryl)ases, testosterone hydroxylase/oxidase, 7-methoxy-4-trifluoromethyl-coumarin demethylase), flavine monooxygenases (toward thiobenzamide), reductases of carbonyl group (toward oracin, 4-pyridine-carboxaldehyde, 1-acenaphthenol, DL-glyceraldehyde, ketoprofene, naloxone, daunorubicin, metyrapone) and cojnugation enzymes (p-nitrophenol-UDP- glukuronosyl transferase, UGT, 1-chloro-2,4-dinitrobenzene glutathione-S-transferase, GST) in old, female mouflons (Ovis musimon, Bovidae), both in healthy ones and those suffered from dicrocoeliosis were studied and compared. This parasitary disease is caused by Dicrocoelium dendriticum. Various methods were used, especially spectrophotometry, spectrofluorimetry, and method based on incubation of enzymes with relative specific substrate followed with HPLC analysis of biotransformation products. The amount of proteins was determined using methods with reduction of..
