In modern urology, it is important to study and understand the features of the development of various pathologies in the organs of the urinary system since the disturbances of the urodynamics is a widespread problem all over the world. Thus, the environment pollution caused by heavy metal salts has unpredictable consequences for the functioning of the urinary bladder. That is why the object of this study is to determine the features of the expression and the quantitative composition of T-cells and macrophages in the UB wall under the intake of the HMS and correction of their effect with vitamin E, as well as during the readaptation period. According to the experimental scenario, the experiment model was implemented by using male rats that were divided into six groups. The heavy metal salts mixture consisted of the most common potentially dangerous metals-microelements (zinc, cooper, iron, manganese, lead and chrome). Vitamin E was chosen as a corrector. To determine the quantitative composition of T-cells and macrophages the immunohistochemical identification by CD3 and CD68 antibodies was used. The main results are presented as M±SD, with the assessment of the differences and dependencies between the groups by using nonparametric Mann-Whitney U test and Spearman’s Rank Correlation Coefficient. We found that the number of CD3+ lymphocytes and CD68+ macrophages differed between the groups and depended on the experimental conditions. Thus, the results of our study demonstrate that the number of T-cells and macrophages in the bladder increases under the influence of heavy metals salts. The simultaneous intake of the pollutants and vitamin E is accompanied by the decrease of expression intensity of the corresponding cells. When the intake of the heavy metals is canceled, the qualitative composition of the identified CD3 and CD68 cells gradually comes to the norm, but the speed of its reduction differs depending on the group of the readaptation. Discovered that the decrease of T-cells and macrophages in the groups with the use of vitamin E was more approached to the control. Based on the results of the immunohistochemical study, a strong correlation between an increased number of the expressed T-cells and macrophages was revealed in the urinary bladder during the whole period of the study that demonstrates the dependence of their activity.
