Delayed cutaneous hypersensitivity reactions in Qigong (chun do sun bup) trainees by multitest cell mediated immunity.

To determine the difference of cellular immunity between a Qigong trainee group and a normal healthy group, skin tests for delayed cutaneous hypersensitivity (DCH) were carried out with ubiquitous seven antigens. The maximal antigen response time was faster in Qigong trainee group (24 hr) and the response antigen number was also higher in the Qigong trainee group (6 antigens) than in normal healthy person (48 hr and 4 antigens). Qigong trainee also had a larger induration diameter (5.14 mm) than normal healthy person (3.79 mm) at 24 hr. Our results represent the difference in cell mediated immunity (CMI) between Qigong trainees and normal healthy subjects.
