METHODS: Adjuvant-induced arthritis rats were treated with acupuncture therapy, Chinese herb treatment or both in combination for one week, then the density of TMPH in heart, liver, kidney, and hind paw was determined by HPLC. The cAMP level in the heart and liver was also measured by radioimmunoassay. The blood changes were detected through the test of blood rheometer.

以佐剂性关节炎大鼠为模型，观察单纯针刺法、单纯药物法及针药结合法分别连续治疗一周后，用HPLC法测定各组大鼠心脏、肝脏、肾脏及病灶局部组织中盐酸川芎嗪的含量；用放射免疫法测定各组大鼠心脏、肝脏中cAMP水平；用血液流变仪测定各组大鼠的血液流变学变化。

RESULTS: Compared with acupuncture and Chinese herb used separately, acupuncture and herb combination significantly decreased the level of reduced viscosity in whole blood, plasma viscosity, blood sedimentation and erythroagglutination index..Significant increases of TMPH in the heart, liver and hind paw tissue except kidney were observed after the combined treatment, which also raise cAMP level in heart and liver.

结果：针药组大鼠的全血还原粘度、血浆粘度、血沉、红细胞聚集指数均较单纯针刺组、单纯药物组显著降低；单位时间内针药组大鼠体内(心脏、肝脏、病灶局部组织)盐酸川芎嗪含量明显高于单纯药物组，肾脏中却无明显增高；同时针药组大鼠心脏、肝脏中的cAMP含量明显高于单纯针刺组和单纯药物组。
