EFFECT OF QIGONG TRAINING ON PROPORTIONS OF T-LYMPHOCYTE SUBSETS IN HUMAN PERIPHERAL-BLOOD

The effect of Qigong training on proportions of T lymphocyte subsets w as investigated in human peripheral blood. We observed that the ratio of CD4+/CD8+ T lymphocytes was increased as much as 50% in a trainee g roup who practiced Qigong training more than 5 months compared to a no rmal healthy group who did not practice. The absolute number of CD4+ T lymphocytes was also elevated in trainee group with 100 cells/mm3 mor e than in normal healthy group. The positive correlation between the r atio of CD4+/CD8+ T lymphocytes and the ratio of CD4+45RA-/CD4+ CD45RA + T lymphocytes was shown in the trainee group. In contrast, there was a negative correlation between the ratio of CD4+/CD8+ T lymphocytes a nd the ratio of CD8+CD57+/CD8+CD57- T lymphocytes in the trainee group . The data indicate that Qigong training affects the profile of lympho cyte subsets in human peripheral blood, especially the proportion of C D4+ T lymphocytes.
