streptococcal-polysaccharide是溶血性链球菌A族菌体成份的一种多糖体(ASP)。在过敏性紫癜患者血中测定ASP抗体效价来探讨过敏性紫癜与溶血性链球菌感染的关系是一种新的观点。作者对例18发病时间在3个月以内的过敏性紫癜患儿测定了ASP、ASO、ASK抗体进行对照分析。结果过敏性紫癜患儿ASP、ASO、ASK抗体阳性率分别是61%、39%、28%。同时还并用其它检查方法提高了血清学诊断率,在ASO、ASK、ASP抗体阳性 Streptococcal-polysaccharide is a polysaccharide (ASP) of hemolytic group A bacteria. Determination of ASP antibody titers in the blood of patients with allergic purpura to explore the relationship between allergic purpura and hemolytic streptococcal infection is a new point of view. The authors examined 18 patients with allergic purpura onset of time within 3 months measured ASP, ASO, ASK antibody control analysis. Results The positive rates of ASP, ASO and ASK in children with Henoch-Schonlein purpura were 61%, 39% and 28% respectively. At the same time also with other tests to improve serological diagnosis, ASO, ASK, ASP antibody positive
