Methods: Male SD rats were randomly divided into groups according to the sucrose preference test and body weight (n = 12). Except the normal control, the other groups were treated with the chronic stress stimulation combined with radiation respectively to establish the model of syndrome of stagnation of liver qi and blood deficiency. The body weight, visceral index and the quantity of Leucocyte, Red Blood Cells, Hemoglobin in peripheral hemogram were monitored, then plasma and serum were separated. Radioimmunoassay was used to analyze the levels of Lnterleukin-3, Granulocyte-macrophage Colony-stimulating Factor, Lnterleukin-6 and Tumor Necrosis Factor-α in plasma. Results: Compared with that of model group, 30 mg·kg^-1 PF and 30 mg·kg^-1 AF of the weight, spleen index, quantity of Leucocyte were increased significantly (P 〈 0.05, P 〈 0.01). The results of Radioimmunoassay showed that the levels of Interleukin-3 increased (P 〈 0.05, P 〈 0.05) and the levels of Tumor Necrosis Factor-α decreased in both 30 mg·kg^-1 PF and 30 mg·kg^-1 AF groups (P 〈 0.05, P 〈 0.05). Conclusion: The effect of PF and AF on the regulation of bone marrow hematopoietic system and immune system play a role in the blood of rats with syndrome of stagnation of liver qi and blood deficiency, which suggests that both of them are the main active ingredients of nourishing blood and smoothing the liver of Baishao.展开更多
