Hematopoietic effect of small molecular fraction of Polygoni multiflori Radix Praeparata in cyclophosphamide-induced anemia mice / 中国天然药物

ABSTRACT

The aim of this study is to investigate the protective effects of a small molecular fraction (SMF) of Polygoni multiflori Radix Praeparata (PMRP) in a cyclophosphamide (CTX) induced anemia mouse model. Small molecular fraction of PMRP was prepared and identified by high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (HPLC-Q-TOF-MS). In pharmacology, we examined the peripheral hemogram and thymus and spleen index. The content of granulocyte-macrophage colony-stimulating factor (GM-CSF) in serum was mensurated by enzyme-linked immunosorbent assay (ELISA); The level of superoxide dismutase (SOD), catalase (CAT), total antioxidant capacity (T-AOC), and malondialdehyde (MDA) in serum and spleen tissue homogenate were detected, and glutathione peroxidase (GSH-PX) was assayed in spleen. The results show that SMF can significantly accelerate the recovery of peripheral hemogram, increase the activity of antioxidant enzymes and GM-CSF in serum and spleen. SMF also increases the number of spleen cells, improves bone marrow pathology. In conclusion, the SMF of PMRP promoted the recovery of hematopoietic function in a CTX-induced anemia mouse, which can support SMF to be used as an adjunct to chemotherapy to counteract its side effects.
