气功对应激状态时免疫功能变化的影响

对练气功者在应激状态下唾液内的ＳＩｇＡ及尿内皮质醇和儿茶酚胺（ＣＡ）含量进行了测定。发现老年气功组在应激状态下ＳＩｇＡＥ有显著升高并保持一定时间；皮质醇和ＣＡ未见升高。而老年对照组在应激状态下ＳＩｇＡ变化不显著；皮质醇和ＣＡ显著升高。上述结果表明在轻度应激状态下练气功对免疫功能有向上调整的倾向，并可降低皮质醇和ＣＡ反应。但不同功法可能产生不同的效应，青年气功组所练功法不同于老年气功组，青年气功组中未见到上述效应

Effects of Qigong on change of immune function during psychological stress

The study is concerned with stress in two groups:aged qigong group and young qigong group,all of them practised qigong more than one year.Content of the salivary SIgA and urinary excretion of cortisol and catecholamines (CA) were obtained during psychological stress.The results showed that in aged qigong group stress SIgA increased significantly and still maintained this level one hour after stress;urinary excretion of cortisol and CAs were no change.But in aged control group no significant change of SIgA was observed;cortisol and CAs increased significantly during stress.These results suggest that during mild stress condition,immune function tended to be elevated and response of cortisol and CAs decreased in these persons who practise qigong.However,in the young qigong group who practised different type of qigong,these effects mentioned above haven't been observed.It suggests that different type of qigong maybe have different effects.
