Effects of qigong waiqi (emitted qi) on immune function of immunosuppressed mice

In this paper the immunosuppressed model of NIH mice induced by cyclophosphamide (CY) was used to study the immunoregulation of qigong waiqi.

The results are as follows:

(1) The thymus index of CY group was obviously lower than the normal control group (P<0.001), but the thymus index of CY + qigong waiqi group was significantly higher than that of the CY group (P<0.05). There was no difference between normal control group and CY + qigong waiqi group (P>0.05). It is shown that qigong waiqi could alleviate the injury of thymus induced by CY.

(2) The antibody production in CY + qigong waiqi group immunized with SRBC was obviously increased as compared with the CY group (P<0.05), but the antibody level was obviously lower than the normal control group (P<0.001). It was revealed that qigong waiqi could protect partially B lymphocyte from CY suppression, and increase the antibody production.

(3) NK cell is a killer cell. It can kill the tumor cell. We found that qigong waiqi could raise the activity of NK cell of the immunosuppressed mice. The lysis rate of CY + qigong waiqi group was 21.7% and was higher than that of CY group (13%).

This paper showed that qigong waiqi could improve the immune function of the immunosuppressed mice induced by CY. Qigong waiqi could alleviate the injury of the thymus, protect partially B lymphocyte from CY suppression, increase the antibody production and raise the activity of NK cell.
