| Summary: | 碩士 === 中國醫藥大學 === 針灸研究所碩士班 === 99 === Traditional Chinese Medicine (TCM) uses hot energy induced by burning moxa floss on the acupoint of body surface to modulate the balance of Yin, Yang, Qi and blood for the treatment of disease that is so called moxibustion. Human body surface causes burn injury by burning Moxa and also causes air pollution. In recent years, far-infrared ray has been widely used in auxiliary treatment of acupuncture, according to the report that the range of spectrum in the generation of far-infrared ray illumination is similar to the spectrum from human body. The effect of far- infrared rays illumination on human body remains unclear until now. The Zhongwan (CV12) acupoint locates in the central point of epigastric region and the qi of six-fu is convergent to this point in theory of TCM. Therefore, the purpose of the present study was to investigate the changes of skin blood flow and skin temperature of CV12 and central part of right palm. A total of 22 healthy volunteer were studied, they accepted far infrared ray illumination focusing on the CV12 and the scope is 10 cm in diameter. The skin blood flow and skin temperature were recordings on the CV12 point and central part of right palm by using a Laser Doppler Perfusion and Temperature Monitor. Each subject received two sessions of sham far-infrared ray illumination and far-infrared ray illumination. Each session divided into pre-illumination, illumination and post-illumination periods. Each period was 20 minutes. In addition, we took 2.5 cc bloods from their left cubital vein for the measurement of calcitonin gene related peptide (CGRP) at the finishing recordings of pre-illumination period and at the finishing recordings of post-illumination period, respectively. The results indicated that far-infrared rays illumination at CV12 can increased skin temperature of CV12 region between illumination and pre-illumination periods, between post-illumination and illumination periods, and between post-illumination and pre-illumination periods, whereas far-infrared rays illumination could not affect skin blood flow and the concentration of CGRP.
In conclusion, far-infrared ray illumination can increase skin temperature of illumination region, and this effect of far-infrared ray illumination can maintain at least 20 min after stopping illumination. As regard to the relationship between far-infrared ray illumination and skin blood flow, and CGRP needs further study.
