title: Effect of qigong training on proportions of T lymphocyte subsets in human peripheral blood.
abstract: The effect of Qigong training on proportions of T lymphocyte subsets was investigated in human peripheral blood. We observed that the ratio of CD4+/CD8+ T lymphocytes was increased as much as 50% in a trainee group who practiced Qigong training more than 5 months compared to a normal healthy group who did not practice. The absolute number of CD4+ T lymphocytes was also elevated in trainee group with 100 cells/mm3 more than in normal healthy group. The positive correlation between the ratio 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 and the ratio of CD8+CD57+/CD8+CD57- T lymphocytes in the trainee group. The data indicate that Qigong training affects the profile of lymphocyte subsets in human peripheral blood, especially the proportion of CD4+ T lymphocytes.
