Polysaccharide of spirulina on the prophylaxis and treatment of myelosup pression of mice caused by cyciophosphamide

Aim The effect of polysaccharide of spirulina on mouse myelosuppression induced by cyclophosphamide was studied. Methods Mice in the model, treatment groups Ⅰ and Ⅱ were given cyclophosphamide (ip 100 mg · kg- 1) for there days. At the same time mice in the treatment groups Ⅰ and Ⅱ were given ig spirulin 30 mg · kg-1 and 60 mg · kg-1 for ten days, while mice in the control group and model group were given ip 20 mg · kg-1 of NS. Peripheral blood and marrow cytometry, micromcelsus and chromosome aberration were analyed. Results In the dosages of 30 and 60 mg · kg-1 polysaccharide of spirulina, the polysaccharide of spirulina had perfect action on the perihemateikon and the function of bone hematoplast induced by cyclophosphamide (P ＜0.01) and antagonistic action on increase of bone cell micronuclsus(P＜0.05); The ratio of chromosome aberration in the treated group was lower compared with that in the model group. The inhibitory ratio was 51.2% and 62.5% in the treated groups Ⅰ and Ⅱ .Conclusion Polysaccharide of spirulina can perfect the hematoplast function of mice injured by cyclophosphamide.
