采用0.25％石炭酸生理盐水配制的含蛋白质量为500μg/ml的姜片虫成虫纯化抗原(PAA)及姜片虫排泄-分泌纯化抗原(PESA),对24例姜片虫病患者作皮内试验,阳性率分别为91.67％(22/24)和100％(24/24),且后者的反应强度亦较大。但反应强度与感染度不呈正相关或负相关(Rs=0);反应结果似与蛔虫、鞭虫等线虫的混合感染无关。对10名血吸虫病人作皮内试验,结果均为阴性。
The purified antigen (GPA) of Zingiber officinale from 500μg / ml and the excretion-secreted antigen of ZGP (PESA) were prepared from 0.25% carbolic acid saline, and 24 cases of zingiber officinale , The positive rates were 91.67% (22/24) and 100% (24/24), respectively, and the latter was more reactive. However, there was no positive or negative correlation between the reaction intensity and the degree of infection (Rs = 0). The result of the reaction seemed not to be related to the mixed infection of worms, worms and other nematodes. Ten patients with schistosomiasis for skin test, the results were negative.
