ABSTRACT
OBJECTIVE:
To observe the effect of electroacupuncture (EA) of "Zhongwan" (CV12) and "Zusanli" (ST36) in different combinations of stimulating parameters on intragastric pressure (IGP) in normal rats so as to explore their best combinations for promoting gastrointestinal mobility.METHODS:
A total of 90 male SD rats were randomly divided into 6 EA groups:CV12-1 mA+ST36-1 mA, CV12-1 mA+ST36-2 mA, CV12-1 mA+ST36-4 mA, ST36-1 mA+CV12-1 mA, ST36-2 mA+CV12-1 mA, and ST36-4 mA+CV12-1 mA which the first acupoint was stimulated first, followed by the second in each group (n=15 rats/group). Before (1 min), and 0-30 s, 30-60 s, 60 -90 s, and 90-120 s during EA stimulation of the left ST36 or CV12 first or later, the IGP was measured via an inserted intragastric balloon, a connected pressure transducer and an amplifier. Changes of the IGP were analyzed using 2×3×4 factorial design.RESULTS:
1) During 0-30 s, EA-CV12 showed an obvious inhibitory effect on IGP(P0.05). 2) Compared with the IGP level of 0-30 s, the IGP levels of 30-120 s were significantly decreased in all the groups (P0.05).CONCLUSION:
Simultaneous EA stimulation of ST36 and CV12 has an antagonistic effect on IGP in normal rats, which is affected by the stimulating sequence, stimulating strength and time course.
