ABSTRACT

Objective:

To compare the effects between electroacupuncture (EA) at Chize (LU 5, the He-Sea point of the Lung Meridian) and Shangjuxu (ST 37, the lower He-Sea point of the large intestine) in rats with ulcerative colitis (UC) on the variations of mesenteric microcirculation and vasoactive intestinal peptide (VIP) in the colon, lung, and hypothalamus. The relative specificity of acupoints was also explored.

Methods:

A total of 28 male Wistar rats were randomized into a normal group, a model group, a Chize (LU 5) group and a Shangjuxu (ST 37) group, 7 rats in each group. The UC model was established by enema with acetic acid. Since the third day after modeling, rats in the Chize (LU 5) group and Shangjuxu (ST 37) group respectively received EA at Chize (LU 5) and Shangjuxu (ST 37), 15 min each time for successive 7 d. The variations of mesenteric microvascular calibers and blood flow status were observed by a microcirculation microscopic tester; VIP in the colon, lung and hypothalamus was measured by radioimmunoassay.

Results:

Compared with the normal group, the mesenteric microvascular calibers were significantly expanded in the model group (P0.05); compared with the model group and Chize (LU 5) group, the calibers were obviously shrunk in Shangjuxu (ST 37) group (P0.05). The colonic VIP levels in the model group and Chize (LU 5) group were significantly higher than that in the normal group (P0.05).

Conclusion:

The effects of Chize (LU 5) and Shangjuxu (ST 37) were different in treating UC. Shangjuxu (ST 37) showed a more significant efficacy in down-regulating VIP in the colon and regulating mesenteric microcirculation, while the effects of Chize (LU 5) were not obvious.
