摘要
为探讨黄芪多糖对环磷酰胺引起副作用的影响，我们应用溶血空斑形成（ＰＦＣ）实验观察了黄芪多糖（ＡＰＳ）２５０ｍｇ，５００ｍｇ，１０００ｍｇ／ｋｇ口服对环磷酰胺（ＣＹ）５０ｍｇ／ｋｇ皮下注射所致实验小鼠免疫低下的作用，结果表明黄芪多糖可拮抗环磷酰胺所致免疫低下，分别使溶血空斑计数据高了３５４．６％，１８６．６％，１３８．６％，提示黄芪多糖对环磷酰胺所致体液免疫障碍有明显改善作用。
To find the optimal dosage of astragalus polysaccharides in regulation of immunity , the effectiveness of astragalus polysaccharides against lowered immune function due to administration of cyclophosphamide was observed in five groups of mice . The as- tragalus polysacccharides were given orally in doses of 250 mg/kg , 500 mg/kg and l000 mg/kg , while cyclophosphamide 50 mg/kg was given by hypodermic injection . The results showed that plaque forming cells were increased 354.6% , 186.6% and 138.6% , respec- tively , suggesting that the astragalus polysaccharides can antagonize the action of cyclophosphamidecausing low immunity . It is conclud- ed that the astragalus polysaccharides can avert the cyclophosphamide - induced humoral immunity decline side effect , and the optimal dose is 250 mg/kg .
