The infrared radiation spectrum of acupoint taiyuan (LU 9) in asthma patients

OBJECTIVE]:To analyze the distinctive pathological characteristics in the spectrums of spontaneous infrared radiation at the Taiyuan (LU 9) acupoint in patients with asthma.METHODS]:A highly sensitive infrared spectrum detecting device was used to detect the spectrums of spontaneous infrared radiation at Taiyuan (LU 9) in 37 asthma patients and 34 healthy volunteers.RESULTS]:Asthma patients had significantly lower infrared intensity than that of the healthy volunteers (P＞0.01).Asthma patients had significantly lower overall infrared radiation intensity at the left Taiyuan (LU 9) than that of healthy volunteers (P＞0.05),but there was no significant difference between healthy volunteers and asthma patients at the right Taiyuan (LU 9) (P＞0.05).The infrared radiation intensity of 17 wavelength spots at the left Taiyuan (LU 9) and 4 wavelength spots at the right Taiyuan (LU 9) in asthma patients were significantly lower than those of healthy volunteers (P＞0.05).At 2 μm,the infrared radiation intensity of asthma patients was significantly stronger than that of healthy volunteers (P＞0.05).At 19 wavelength spots in the healthy volunteers and at 4 wavelength spots in the asthma patients,the left Taiyuan (LU 9) showed a significantly stronger intensity than that of the right Taiyuan (LU 9) (P＞0.05).By Pearson's X2 test,healthy volunteers had more wavelength spots that were significantly different between the left and right Taiyuan (LU 9) than the asthma patients (P＞0.01).CONCLUSION]:Changes in the infrared spectrum at the Taiyuan (LU 9) acupoint in asthma patients may reflect distinct pathological changes.Certain acupuncture points may be related to specific organs.
