title: [Comparative study on infrared radiation spectrum of yuan point and Xiahe point of the large intestine channel in the patient of ulcerative colitis].
abstract: OBJECTIVE
  To probe the diagnostic value of the infrared radiation spectrum of acupoint for ulcerative colitis (UC).
  
  
  METHODS
  A high sensitivity PHE 201 infrared spectrum instrument was used to determine the infrared radiation spectrum of Hegu (LI 4) and Shangjuxu (ST 37) in 34 cases of UC.
  
  
  RESULTS
  Of 59 waves detected, there were significant differences in infrared radiation intensity of 28 different waves between the healthy people and the patients with UC in right Hegu (LI 4) (P < 0.05 or P < 0.01) and 13 waves in left Hegu (LI 4) (P < 0.05); there were significant differences in 16 different waves in right Shangjuxu (ST 37) (P < 0.05 or P < 0.01) and in 17 waves in left Shangjuxu (ST 37) (P < 0.05 or P < 0.01); there was a significant difference in 18 waves between right and left Hegu (LI 4) of the patients (P < 0.05 or P < 0.01) and 7 waves between right and left Hegu (LI 4) of the healthy people (P < 0.05). There was a significant difference in 4 waves between right and left Shangjuxu (ST 37) of the patients and one wave between right and left Shangjuxu (ST 37) of the healthy people (P < 0.01).
  
  
  CONCLUSIONS
  Both Hegu (LI 4) and Shangjuxu (ST 37) show changes of infrared radiation spectrum when the intestine gets lesion, and Hegu (LI 4) can better show the change.
