The antitumor effects of Qigong-emitted external Qi and its influence on the immunologic functions of tumor-bearing mice

Abstract

By utilizing marine tumor models bearing Ehrlich ascites carcinoma (EAC) and ascitic Sarcoma-180 (S-180), we investigated the in vivo antitumor effects of QEQ or/and the chemotherapeutic agent cyclophosphomide (CY) and their influence on the splenic natural killer (NK) activity, macrophage-mediated tumor cytolysis (MTC) activity and interleukin-2 (IL-2) production level of different groups of TBM. The results demonstrate that Qigongemitted external Qi (QEQ) has inhibitory effects on tumor growth of tumor-bearing mice (TBM) and enhancing effects on antitumor immunologic functions of the tumor host simultaneously. Moreover, when used in combination with CY, QEQ can not only significantly increase the antitumor efficacy, but also markedly improve the compromised antitumor immunologic functions of the tumor host. Therefore, our findings suggest that in clinical practice of cancer treatment Qigong therapy in combination with conventional therapy (such as chemotherapy) is a treatment regimen worth recommending.
