[Effect of qigong exercise on the blood level of monoamine neuro-transmitters in patients with chronic diseases]

In this study, the authors, by means of fluorescence spectrophotometry,
observed the variations of blood contents of monoamine neuro-transmitters (5-hydroxytamine 5-HT; norepinephrine NE; dopamine DA) in 68 subjects before and after adoption of Qigong exercises. A comparison of pre- and post-exercise showed a general reduction in 5-HT, varying from 0.43 +/- 0.21 to 0.21 +/- 0.13 microgram/ml (P less than 0.001). Variations in NE and DA tended to go up, NE being from 0.27 +/- 0.13 to 0.35 +/- 0.27 microgram/ml, DA from 0.86 +/- 0.69 to 1.19 +/- 0.81 micrograms/ml (P less than 0.02). Effects of Qigong exercises on different diseases: Subjectsin each group showed reduction in blood 5-HT content after they had practised Qigong exercise. (1) Cardiovascular disease: 0.47 +/- 0.34 to 0.16 +/- 0.11 microgram/ml (n = 13); (2) gastric diseases: 0.37 +/- 0.19 to 0.22 +/- 0.13 microgram/ml (n = 20); (3) joint system diseases: 0.44 +/- 0.21 to 0.18 +/- 0.13 microgram/ml (n = 10); (4) respiratory system diseases: 0.40 +/- 0.22 to 0.22 +/- 0.12 microgram/ml (n = 8); (5) other diseases (neuroasthenia, neurosis, etc.): 0.46 +/- 0.22 to 0.25 +/- 0.14 microgram/ml (n = 13). In all these groups except the fourth group, variations in 5-HT content in comparison with the pre-exercise values were respectively P less than 0.01, less than 0.01, less than 0.05, less than 0.05. The difference was obvious.The post-exercise blood content of DA in various groups rose up remarkably.(ABSTRACT TRUNCATED AT 250 WORDS)
