摘要
采用双抗体夹心ELISA法,检测47例晚期日本血吸虫病患者血清可溶性白细胞介素-2受体(sIL-2R),同时用间接免疫荧光法测定其外周血单个核细胞(PBMCs)膜IL-2受体(mIl-2R)的表达水平。结果表明晚血患者血清sIL-2R较正常人明显增高,而mIl-2R表达明显低下(P<0.01),其sIL-2R水平与mIl-2R表达呈负相关(r=-0`62,P<0.01).血清sIL-2R高低与COPT阳性与否无关,说明患者血清sIL-2R高低与病原体本身无直接关系,而与患者是否伴腹水有关,提示sIL-2R水平与疾病进展程度有关。观察患者血清sIL-2R的高低可作为疾病病程的监测指标。
The survey of the soluble IL-2 receptor (sIL-2R) level in the sera and the membrane IL-2 receptor (mIL-2R) expression on the peripheral blood mononuclear cells (PBMCs) from 47 cases of late schistosomiasis japonica was reported. The measurement for sIL-2R was done with the double antibody sandwich ELISA. Indirect immunflurescence was performed in the measurement for mIL-2R. The levels of sIL-2R in sera from 47 patients with late schistoso-miasis was found to be higher than that in control (P<0. 01) ; while the mIL-2R on PBMCs, was lower in comparing with control (P<0. 01). The negative correlation was found between the levels of sIL-2R in sera and the expression of mIL-2R on PBMCs in these patients (r= -0. 62. P<0. 01). That no relationship exists between the levels of sIL-2R and the result of COPT suggests that high levels of sIL-2R might not be due to the direct effect of parasite itself. Therefore late schistosomiasis should be recognized as an immune disorder, and the levels of sIL-2R were related to ascites. It is suggested that sIL-2R could be considered as an efficient indicator for surveillance of schistosomiasis.
