| Abstract: |
| 本文报道应用竞争性固相放射免疫分析法测定流脑患者血清和CSF中CRP的水平。发现流脑患者血清CRP含量约为健康人的400~500倍;其急性期血清CRP水平(28.5~540μg/ml,中位数200μg/ml)比恢复期(0.1~54μg/ml,中位数0.53μg/ml)高出300~400倍。从CSF中也能检测到较低水平(0.07~150μg/ml,中位数2.07μg/ml)的CRP。结果充分显示CRP作为急性相反应物质的特征。因此,CRP水平的测定,可为细菌性和非细菌性脑膜炎的鉴别诊断和疾病过程的监测,提供重要的辅助指标。 |
| English Abstract: |
| A modified solid phase RIA was developed for the quantification of C-reactive protein in human serum and CSF. The lowest measurable amount detected by this method was 5 ng/ml (0.25ng/well). The serum levels in 68 healthy blood donors were with in the range from 0.028~3.4μg/ml. with a median value of 0.166μg/ml (mean=1.57μg/ml); whilst those in 63 patients with epidemic cerebrospinal meningitis were up to 520μg/ml with a median value of 77.5μg/ml(mean=83.46μg/ml). This is 400~500-fold higher than that of the normal. The levels of CRP in the sera collected during acute stage of the infection (ranged from 28.5~540μg/ml, with a median value of 200μg/ml, mean=200.6μg/ml)were 400-fold higher than that after recovery(ranged from 0.1~54μg/ml, with a median value of 0.53μg/ml). In addition, lower levels (0.07~150μg/ml, median=2.07μg/ml) of CRP were detected in CSF. These results markedly revealed that the CRP reflected the characteristics of an acute phase protein in the infection, and would be usefull for the differential diagnosis of bacterial and nonbacterial meningitis, and in monitoring the clinical course of the illness. |
