M. Regeda   Lviv National Medical University named after Danylo Halytsky, Ukraine Health Ministry of Ukraine, Kiev, Ukraine   Abstract In a gradual decrease in the content of T-lymphocytes and increased B-lymphocytes and circulating immune complexes (CIC) in the blood for 4-th, 8-th, 10-th and 18-th in the era of the development of periodontitis on the background of experimental pneumonia compared with control. Use (EP) thiotriazoline led to an increase in the level of T-lymphocytes and a decrease in the content of B -lymphocytes and the CIC with periodontitis and EP. Key words: periodontitis, experimental pneumonia, immune system, thiotriazolin.
