Abstract:
Aim To investigate the protective effect of Citrus aurantium L. polysaccharides-B(CALB) on ra-diation induced by 60Co γ-ray in mice. Methods The BALB/c mice were randomly divided into blank control group, radiation model group, CALB administration group (high, medium and low dose), and positive control group(black fungus polysaccharide,HP). The mice were administered orally for 30 days. After the last administration for three hours,the survival rates on the 2nd day and the 14th day of the blank control group and the irradiated mice after the single radioac-tive irradiation (7 Gy) with 60Co γ-ray were meas-ured. In addition, DNA content and micronucleus of bone marrow cells, SOD, GSH-Px activities, MDA content in serum, liver and brain tissues in mice, TChE activity in brain tissues and spleen and thymus index of mice were detected after one-time whole body irradiation with 60Co γ-ray (3 Gy). Results Each dose group of CALB could significantly improve the survival rate of irradiated mice,increase the DNA con-tent of mouse bone marrow cells and reduce the number of micronuclei in bone marrow cells. In addition, CALB could also increase the thymus and spleen index and the levels of SOD and GSH-Px in serum,brain and liver tissues of mice,and reduce the content of MDA. Conclusion CALB has protective effect on radiation injury,which can be used for further development and utilization of Fructus aurantii.
