In this experiment, NlH mice were divided into three groups randomly: (l)the normal control group, (2) the stressed control group (Mice underwent 5 min of 14°C±l°C/day cold stress exposure for 8 days), (3) the qigong groups (besides cold-stress, mice received emitted qi 30 min/day for 8 days). Then, the index of thymus,spleen and brain were detected, T cell, B cells proliferation and the RDCC activity of K cell were used to investigate the immune adjusting effect of the emitted qi on cold-stressed mice.
Our study demonstrated:
(l): The T,B cell proliferation rate of the stressed mice (10084±549; 5074±499) was obviously lower than that of the non-stressed mice (18270±1069; 13704±855) p<0.01, but the T,B cell proliferation of the qigong group (23582±1959; 14601±900) was obviously higher than that of the stressed mice group (p<O.01).
(2) The activity of K cell RDCC of the stressed mice (O.128±0.004) was obviously lower than that of the non-stressed mice (O.479±0.007, p<0.001), but the emitted qi can enhance the RDCC activity of the stressed mice (O.5O5±O.001, p<O.001).
(3) 1n cold stress environment, the immune organs (thymus and spleen) of mice were atrophied more significantly (3.57±0.64; 4.76±0.75) than the non-stressed mice (4.28±0.63; 5.67±1.06, p<0.01), but the emitted qi can alleviate the injury of the thymus and spleen (4.10±0.49, p<0.01; 5.22±1.06, p>0.05).
(4) The weight of brain of the stressed mice were lighter (20.6±1.5) than the non-stressed mice (22.0±1.4, p<0.05), but the emitted qi can increase the brain weight of the stressed mice (22.2±1.5, p<0.01).
