不同灸量隔花椒灸对RA大鼠穴位局部温度影响实验观察

Experimental Investigation of Temperature Influence in Local Acupoints of Rheumatoid Arthritis(RA)Rats Treated by Different Quantities of Pepper-separated Moxibustion

目的:观察不同灸量隔花椒灸对RA大鼠穴位局部温度的影响,探寻隔花椒灸对腧穴局部温热刺激的变化规律及特性。方法:用温度记录仪分别测量RA大鼠隔花椒灸3壮及5壮灸前后穴位温度,并对施灸前、施灸过程中及施灸后2个穴(肾俞、足三里)表面温度变化进行比较。结果:两种不同灸量隔花椒灸中,肾俞和足三里穴位表面温度上升达到的最高温度不同。5壮灸组所达到的最高温度和上升温度均比3壮灸组高,差异具有统计学意义(P<0.05,P<0.05)。隔花椒灸施灸结束后,2组不同灸量中两穴位的表面温度(终末温度)差异无统计学意义。结论:不同灸量刺激对穴位局部的温度产生重要影响,隔花椒灸5壮灸温热效应较3壮灸更能到达穴位皮肤产生作用,不同穴位隔花椒灸的温热效应还待进一步研究。

Objective ： To observe the quality of temperature changes before and after different quantities of pepper-separated moxibustion, and explore the change rule and characteristic of pepper-separated moxibustion＇s heating stimulate on treating rheumatoid arthritis （ RA ） rats. Methods ： Local acupoint temperatures of different quantities of pepper-separated moxibustion （ 3 Zhuang, 5 Zhuang ） were measured respectively in RA rats, and then a comparison of surface temperature changes in （ Shenshu BL23, Zusanli ST36 ） was made among pre-moxibustion, moxibustion-session and post-moxibustion. Results ： The maximal temperature of Shenshu and Zusanli between the two quantities of pepper-separated moxibustion were different. The maximal temperature and elevated temperature of 5 Zhuang groups were both significantly higher than those of 3 Zhuang groups （ P〈0.05, P〈0.05 ）. When the separated moxibustion completed, it showed no statistic significance in surface temperature （ terminal temperature ）. Conclusion ： The heating stimulation in different quantities of pepper-separated moxibustion plays an important role in affecting the temperature of local acnpoint, in which the heating effect of 5 Zhuang groups was much better than that of 3 Zhuang groups. As for the heat effect of different acupoints in moxibustion, further research is needed.
