目的:应用多指标综合指数法与三维响应曲面分析法研究当归-红花(GH)补血效应的配伍规律。方法:采用注射乙酰苯肼+环磷酰胺诱导的小鼠血虚模型,将实验动物分为正常组、模型组、当归-红花不同配比(1∶0,4∶1,2∶1,3∶2,1∶1,2∶3,1∶2,1∶4,0∶1)组,按剂量0.01 m L·g^(-1)灌胃给药,连续7 d,观察小鼠血常规和脏器指数(胸腺、脾脏)的变化,建立当归和红花配伍后的三维响应曲面模型。结果:单用当归剂量为7.8 g·kg^(-1)·d^(-1)时,补血效果最好,总效应值5.50;单用红花剂量为0.52 g·kg^(-1)·d^(-1)时,补血效果最好,总效应值4.57。当归和红花配伍后,当归剂量在0.5~1.2 g·kg^(-1)·d^(-1)和红花剂量在0^0.5 g·kg^(-1)·d^(-1)时,表现为协同作用,在大部分剂量配比范围内(约50%)表现为相加作用,其次为拮抗作用。结论:当归和红花配伍后补血效应的协同作用范围较窄,强度也不是很明显,并在一定量比时还有拮抗作用。
Objective: To demonstrate the pharmacodynamic interaction in tonifying blood of couplet medicines of Angelicae Sinensis Radix and Carthami Flos by comprehensive index method and three-dimensional response surface method. Method: Based on mouse blood deficiency model induced by injection of acetylphenylhydrazine (APH) and cyclophosphamide (CTX), the effect of this couplet medicines with different proportions (1:0, 4:1, 2:1, 3:2, 1:1, 2:3, 1:2, 14, 0:1) and different concentrations on the peripheral blood indexes and organ indexes were observed. Then all indexes were integrated and analyzed by relative equation. The three-dimensional response surfaces were gained by Matlab R2010a software. Result: When theywere used singly, the best doses of Angelicae Sinensis Radix and Carthami Flos were 7.80, 0.52 g·kg-1·d-1, respectively. Most dose (about 50% ) of this couplet medicines exhibited addition action, followed by antagonism, and little dose (0.5-1.2 g. kg - 1·d -1of Angelicae Sinensis Radix and 0-0.5 g· kg - 1. d - 1 of Carthami Flos) had synergetic effect. Conclusion : The range of synergetic effect of this couplet medicines on tonifying blood is little, and the intensity is not obvious, but it has antagonism in a certain amout.
