[Changes of electrical property of the twelve source-points in encephaloma patients before and after surgery].

OBJECTIVE
To observe the changes of electrical property of the 12 Source-points in encephaloma patients undergoing surgery.


METHODS
A total of 116 encephaloma patients and 60 healthy people who signed the informed consent were enlisted in the present study. The regional cutaneous electric resistance (CER) of the bilateral 12 Yuan (Source)-points was measured in the afternoon (14:00-16:00) before and one week after surgery under room temperature [(22 +/- 3) degrees C, (55 +/- 10)% in humidity] by using "Meridian Energy Analysis Device".


RESULTS
In comparison with normal subjects, CER values of the 12 Source-points on both sides of the body in encephaloma patients were significantly lower (P < 0.01). Before surgery, CER values of Wangu (SI 4), Taibai (SP 3), Taichong (LR 3) and Chongyang (ST 42) on the left side were significantly higher than those of the isonym points on the right side (P < 0.01, P < 0.05), suggesting an imbalance of the bilateral Small Intestine, Spleen, Liver and Stomach Meridians. After surgery, CER values of Shenmen (HT 7), Wangu (SI 4), Yangchi (SJ 4) and Taibai (SP 3) on the left side were markedly higher than those of the isonym points on the right side (P < 0.05, P < 0.01), suggesting an imbalance of the bilateral Heart, Small Intestine, Trienergizer and Spleen Meridians. Comparison between pre- and post-surgery showed that CER values of Taiyuan (LU 9), Daling (PC 7), Taibai (SP 3), Taichong (LR 3), Taixi (KI 3), Jinggu (BL 64), Qiuxu (GB 40) and Chongyang (ST 42) on both sides, and Wangu (SI 4) on the right side lessened obviously post-surgery (P < 0.01, P < 0.05), suggesting an imbalance of the bilateral meridians found in more meridians, including yang meridians entering the brain as the Bladder, Gallbladder, Stomach Meridians.


CONCLUSION
In encephaloma patients, the CER values of some Source-points on the left side are significantly higher than those on the right side, suggesting an imbalance of the bilateral meridians in functional activities.
