Abstract

Objectives : This study was performed to observe the effects of acupuncture at right Nae-jong$(ST_{44})$ on the temperature and humidity changes of Sa-baek$(ST_2)$ area according to the meridian and Keo-ja(巨刺) of oriental medicine's theory. Methods : A clinical study was done on 13 females who didn't have my disease. We used LT-8B to observe the effects of acupuncture at right Nae-jong$(ST_{44})$ on the temperature and humidity changes of Sa-baek$(ST_2)$ area. Skin temperature and humidity on right and left Sa-baek$(ST_2)$ were measured by LT-8B at 1 minute before acupuncture stimulation, 1 minute and 2 minutes after acupuncture stimulation of right Nae-jong$(ST_{44})$. Results : 1. After inserting the needle at the right Nae-jong$(ST_{44})$ point, the temperature at the left Sa-baek$(ST_2)$ area rised from $31.60{\pm}1.13^{\circ}C$ 1 minute before to $32.24{\pm}1.19^{\circ}C$ 1 minute after the insertion and to $32.34{\pm}1.23^{\circ}C$ 2 minutes after insertion, what means an elevation by (P<0.05) between the temperature before and 2 minutes after the insertion and still an elevation by (P<0.01) between 1 minute and 2 minutes after insertion. The humidity at the same area decreased by (P<0.01) between 1 minute and 2 minutes after insertion. 2.After stimulating the right Nae-jong$(ST_{44})$ point the temperature change at the right Sa-baek$(ST_2)$ area between before and after the insertion was unremarkable, however the temperature rised by (P<0.05) between 1 minute and 2 minutes after insertion and the humidity decreased by (P<0.05) between 1 minute and 2 minutes after stimulation. 3. Comparing the temperature change between 1 minute and 2 minutes after stimulating the right Nae-jong$(ST_{44})$ point, we could find a significant difference by (P<0.05) at both Sa-baek$(ST_2)$ areas. Concerning the humidity change, there were some average differences but too small for statistic significance.
