摘　　要：Objective： To verify two hypotheses： 1 ） Acupuncture can increase the re-distribution of tetramethylpyrazine （ligustrazine） hydrochloride （TMPH） to the target organs in adjuvant arthritic rats. 2） Cyclic Adenosine-3＇, 5＇-menophesphete （cAMP） is one of the guidance cues involved in this event. Methods： A total of 40 Wistar rats were randomized into blank control （BC）, model （MO）, medication （ME）, Acupuncture （Acu） and Acu＋ ME groups, with 8 cases in each group. Arthritis model was established by subcutaneous injection of complete Freund＇ s adjuvant （0.1 mL） into the rat＇ s foot pad. Electrcacupuncture （ 15 Hz, 0.2-0.3V） was applied to bilateral “Daling”（大陵 PC 7）, “Taichong” （太冲 LR 3） and “Xiguan” （膝关 LR 7） for 20 min, and the contents of TMPH in the heart, liver, kidney and the foot （affected focus） tissues and the contents of cAMP in the heart and liver tissues were determined with high performance liquid chromatography and radioimmunoassay techniques respectively. Results： Oornpared with medication group, the TMPH contents in the heart, liver, kidney and the affected foot tissues in Acu-ME group was obviously higher （ P〈0.05, P〈0.01 ）. In comparison with ME and Acu groups, the cAMP contents in the heart and liver in Acu＋ ME group was also significantly higher （P〈 0.05, P 〈 0.01 ）. No significant differences were found between ME and Acu ＋ ME groups in TMPH content of kidney and between Acu＋ ME and BC groups in cAMP contents in both liver and heart tissues. Conclusion： Acupuncture may promote the target-tropism distribution of ligustrazine, and cAMP may play an important role in it.Objective: To verify two hypotheses: 1) Acupuncture can increase the re-distribution of tetramethylpyrazine (ligustrazine) hydrochloride (TMPH) to the target organs in adjuvant arthritic rats. 2) Cyclic Adenosine-3’, 5’-monophosphate (cAMP) is one of the guidance cues involved in this event.
