Protection of phosphate esterification polysaccharides from Tremella fuciformis on hematopoietic function in radiation-injured mice / 中草药

ABSTRACT

Objective: To study the effect of phosphate esterification polysaccharides from Tremella fuciformis (PEPTF) on hematopoietic function in radiation-injured mice. Methods: Rats were randomly divided into six groups control, model, polysaccharides from T. fuciformis (10 mg/kg) positive control, low-, mid-, and high-PEPTF (10, 30, and 60 mg/kg) groups. Before irradiated with 137Cs γ-ray, rats were ip administered once daily for 3 d. On the day 7 after irradiation, the rats were sacrificed. Colony-forming unit of spleen, number of nucleated cells in bone marrow, number of white blood cells, spleen index, and thymus index were used as observation indexes to investigate the effect of PEPTF on hematopoietic function of mice. Results: Compared with the model group, the number of the nucleated cells in bone marrow, the number of white blood cells, spleen index, and thymus index of mice increased markedly. Conclusion: PEPTF have the protective effect on the hematopoietic function of radiation-injured mice.
