ABSTRACT
<p><b>OBJECTIVE</b>To explore the mechanism of reinforcing function of moxibustion to spleen-stomach.</p><p><b>METHODS</b>Forty healthy Sprague Dawley rats were randomly divided into 4 groups: group A (blank group), group B (model group), group C (moxibustion group) and group D (herbs group). The rat model of spleen-deficiency was established by intragastric administration with 200% Dahuang (Rhubarb) infusion. The rats in group A and B, and D served as the blank control, model, and Sijunzi decoction group respectively, while those in group C received moxibustion at "Zusanli" (ST 36), "Zhongwan" (CV 12), "Guanyuan" (CV 4), "Pishu" (BL 20) and "Weishu" (BL 21), etc. The common symptoms and intestinal propulsive rate were observed. The content of I-xylose in serum was detected by phloroglucinol method. Colorimetry method was used to detected content of ATP in jejunum tissues.</p><p><b>RESULTS</b>Compared with group A, the symptom score in group B was increased significantly (both P < 0.01), while the intestinal propulsive rates, the content of D-xylose in serum and ATP in jejunum tissues were decreased significantly (P < 0.05, P < 0.01). Compared with group B, the symptom score in group C and D was decreased significantly (both P < 0.01), while the intestinal propulsive rates, the content of D-xylose in serum and ATP in jejunum tissues were increased significantly (P < 0.05, P < 0.01). There were no significant difference between group C and D (P > 0.05).</p><p><b>CONCLUSION</b>Moxibustion at "Zusanli" (ST 36) etc. could relieve symptoms of spleen-deficiency, enhance motility and absorption functions of small intestine and improve metabolism of small intestine. The efficacy is equal to administration of Sijunzi decoction.</p>
