Abstract

Ethnopharmacological relevance: Panax notoginseng (PN) (Burk.) F. H. Chen is a medicinal herb used to treat blood disorders since ancient times, of which the steamed form exhibits the anti-anemia effect and acts with a "blood-tonifying" function according to the traditional use. However, its pharmacological effect and mechanism on alleviating renal anemia (RA) are still unclear.

Aims of the study: The study aims to investigate the effect of steamed Panax notoginseng (SPN) to attenuate RA and its underlying mechanism based on the model of adenine-induced RA mice.

Materials and methods: Seventy mice were randomly divided into seven groups of ten: the control group, model group, the erythropoietin (EPO) group, the Fufang E'jiao Jiang (FEJ) group, the high-dose steamed PN (H-SPN) group, the middle-dose steamed PN (M-SPN) group, and the low-dose steamed PN (L-SPN) group. The adenine induction RA model was applied to assess the "blood enriching" function of SPN. The blood routine indexes, erythrocyte fragility, pathologic morphology of kidney tissue and the expression levels of related cytokines and proteins in the mice were detected after 3-week administration with SPN and positive drugs.

Results: Our study provided evidences that SPN could ameliorate RA. Compared with the control group, SPN could attenuate RA by significantly increasing the numbers of peripheral blood cells (p < 0.01), improving the erythrocyte fragility (p < 0.01), and restoring the expression of EPO mRNA in the kidneys and EPO receptor mRNA in bone marrow nucleated cells. The expression of TGF-β₁ mRNA was declined and the expression of HGF mRNA was significantly increased in a dose-dependent way after the treatment of SPN. Additionally, the expression of Bcl-2 and Bcl-2/Bax ratio in the kidneys were significantly increased. In contrast, there was a highly significant decrease in the expression of Bax (p < 0.01), following SPN treatment.

Conclusion: SPN could alleviate RA by promoting the overall hematopoiesis and inhibiting the progress of renal injury in mice.
