[Effects of scalp acupuncture on regulative ability of oxidative stress reaction at operation stage]

To study on regulative action of scalp acupuncture on oxidative stress reaction at operation stage.

Fifty two cases selected for radical operation of intestinal cancer were randomly divided into a scalp acupuncture plus general anesthesia (scalp acupuncture group) and a simple general anesthesia group (general anesthesia group), 26 cases in each group. The scalp acupuncture group were treated first with scalp acupuncture for 20 min, followed by general anesthesia, with scalp acupuncture lasted till the end of operation. The general anesthesia group were treated only with simple intratracheal anesthesia. Effects of scalp acupuncture on malondialdehyde (MDA) level and superoxide dismutase (SOD) activity at the operation stage were observed.

After operation, MDA levels decreased significantly (P < 0.05) in the two groups, but with no difference between the two groups in the different values of MDA before and after treatment (P > 0.05); there was no significant change in SOD before and after treatment in the scalp acupuncture group, and significantly decreased in the general anesthesia group (P < 0.05). There was a significant difference between the two groups in the different value of SOD before and after the operation (P < 0.05).

Scalp acupuncture can inhibit the decrease of SOD activity, reducing oxidative stress reaction at operation stage.
