Antitumor metastases activity of emitted qi in tumor bearing mice

The effect of the emitted qi preventing tumor metastased in vivo in tumor-bearing mice is reported in this paper. The experiment was conducted with the help of the famous qigong master Hu Jiefu who emitted his qi to C57BL/6 mice inoculated with 2 X 10[power 5] B16 melanoma tumor cells via the tail veins. On days 3, 5, 7, 9 after the tumor cell inoculation, the mice received the emitted qi for 30 min. each time. On day 13, the lungs were harvested and the number of metastatic tumor nodules on the lung surface were counted. The another group of mice were observed for length of survival. Some mice inoculated sc with 1 X 10[power 5] B16 tumor cells were treated with the emitted qi as above and the growth of tumor were determined by measuring the size in perpendicular diameters. The results showed that the emitted qi strongly prevents tumor metastases in vivo. It markedly decreased the number of B16 melanoma pulmonary metastases nodules in the experiment group (10.8 ± 11.93) as compared with the control group (87.4±15.53), the difference being very significant (P< 0.01). The survival period of the experiment mice (31.4 ± 5.27 days) was much longer than that of the control group (21.4 ± 2.70 days) (P< 0.01). These results showed that the emitted qi has the ability to prevent tumor metastases in vivo in experimental tumor-bearing mice. It can also inhibit intradermal tumor growth. Its mechanisms of enhancing the immune function against tumors will be reported in the next paper.
