蜜环菌多糖对环磷酰胺损伤小鼠骨髓细胞的保护作用

目的:观察蜜环菌多糖对环磷酰胺所致小鼠骨髓细胞损伤的保护作用。方法:纯系昆明小鼠 50 只,随机分为5组,正常对照组;阳性对照组(rhG-CSF 20μg·kg^-1·d^-1);环磷酰胺(150 mg·kg^-1·d^-1)损伤组;蜜环菌多糖(25 0 mg·kg^-1·d^-1)低剂量保护组;蜜环菌多糖(50.0 mg·kg^-1·d^-1)高剂量保护组。阳性对照组sc rhG CSF 6 d,ip环磷酰胺3 d。保护组 ip蜜环菌多糖8 d,ip环磷酰胺3 d。记数外周血WBC,RBC,PLT和骨髓细胞悬液WBC,BM NC,骨髓象分析。结果: 保护组、阳性对照组外周血中的WBC,RBC,PLT,骨髓细胞悬液中WBC,BMNC明显高于损伤组,P<0.01;保护组中骨髓早幼粒、分叶核细胞数,高剂量组比低剂量组明显增多。结论: 蜜环菌多糖对环磷酰胺所致小鼠骨髓细胞损伤有较好的保护作用。

Protective effect of Armillaria mellea polysaccharide on mice bone marrow cell damage caused by Cyclophosphamide

OBJECTIVE: To observe the effect of Armillaria mellea polysaccharide on mice bone marrow cells damage caused by Cyclophosphamide. METHOD: Kunming purebred mice were used and stochastic divided into 5 groups: normal control group, positive control group (rhG-CSF 20 microg x kg(-1) x d(-1)), damage group of Cyclophosphamide (150 mg x kg(-1) x d(-1)), the protective group with A. mellea polysaccharide, low dose (25.0 mg x kg(-1) x d(-1)) and high dose (50.0 mg x kg(-1) x d(-1)). Positive control was s.c. rhGCSF 6 d and i.p. Cyclophosphamide 3 d. A. mellea polysaccharide was i.p. 8 d. and Cyclophosphamide i.p. 3 d. WBC, RBC, PLT, BMNC were counted in peripheral blood and bone marrow cells. The myelogram were analyzed in bone marrow. RESULT: The WBC, RBC, PLT, BMNC of protective group and positive control group were higher than damage group (P < 0.01) significantly high dose group increaser than low dose group in protective group the numbed of Promyelocytic and lobulation nuclear of marrow. CONCLUSION: A. mellea polysaccharide has preferably protective effect on damaging mice bone marrow cell caused by Cyclophosphamide.
