The application of radioactive tracers in pathophysiological examinations of domestic and laboratory animals infected with parasites was described. The results of these studies on the turnover of proteins and formation of immune complexes are important for understanding of parasite diseases. The meaning of radioisotopes as an indispensable tool in observations of dynamic processes was demonstrated.
The author reminded of the recommendations of the International Committee of Laboratory Animal Science (ICLAS) concerning the necessity of including in publications information on experimental animals used in the experiments and on methods of hygienics during the experiments (sterilisation of cages, water, food, substrate, ensuring of appropriate physical conditions in breeding and experimental rooms).
