[Methods] The iron-deficiency anemia rat model was established by feeding low-iron diet. Meanwhile, the rats were given oral gavage of ferrous succinate(0.036 g/kg, positive drug group) and Lujingyiqishengxue Pill(4.4, 2.2, 1.1 g/kg, high, middle and low dose groups), once daily for 42 consecutive days. The body weight of the rats was observed every week, and the peripheral blood[red blood cells(RBC), hemoglobin(HGB), and hematocrit(HCT)]and the iron contents in tissues(the liver, spleen, small intestine, kidney) of the rats were detected after modeling;and serum iron(SI), serum total iron binding capacity(TIBC), transferrin saturation(TSAT), serum ferritin(SF) and serum transferrin receptor 1(TFR1) and other iron metabolism indexes were determined. [Results] Compared with the model group, the high-dose Lujingyiqishengxue Pill significantly reversed the peripheral blood(HGB, HCT) and iron contents of various tissues(the liver, spleen, small intestine, kidney) in rats(P<0.01), and significantly increased SI, TSAT, SF(P<0.01), while the contents of TIBC and TFR1 were significantly decreased(P<0.01). [Conclusions] Lujingyiqishengxue Pill can significantly improve anemia and regulate iron metabolism in rats with iron-deficiency anemia, which provides a pharmacological reference for the clinical application of Lujingyiqishengxue Pill.展开更多
