RESUMEN

Objective To determine the changes of cerebrospinal fluid(CSF) ?-endorphin(?-EP) and C-reactive protein(CRP) in children with central nervous system(CNS) infection.Methods Sixty-five children suffered from CNS infection were determined the plasma and CSF ?-EP and CRP concentration during the acute and recovering stage with radioimmunoassay, which included 48 viral encephalitis, 12 purulent meningitis and 5 tuberculou meningitis,and 24 non-CNS disease children were as control group.Results The concentrations of plasma and CSF ?-EP of every experimental group were obviously higher than those of control group during the early stage of CNS infection and these were obviously lower during the recovering stage. The serum concentration of CRP during acute stage was significantly higher than that during recovering stage. No change of serum and CSF CRP concentration was determined during either the acute or recovering stage in the other two experimental groups.Conclusions Determining the plasma and CSF ?-EP is mea-(ningful) in early diagnosis of CNS infection,and determining the serum CRP at the same time may be helpful in differentiating septic and inseptic infection.

RESUMEN

<p><b>OBJECTIVE</b>To analyze the change of EB virus VCA/IgA and EA/IgA titer during the development of nasopharyngeal carcinoma (NPC), and the role in screening for NPC.</p><p><b>METHODS</b>VCA/IgA and EA/IgA were monitored in a period of 12 years by immunoenzymatic titration from the sera of 54 NPC patients after primary serological screening.</p><p><b>RESULTS</b>VCA/IgA and EA/IgA titer had shown gradual increment 1 - 7 years before NPC was pathologically diagnosed. The mean titer of VCA/IgA was 1:21.04, 7 - 4 years before diagnosis. VCA/IgA titer ascended quickly within 3 years before diagnosis. The geometric mean titer (GMT) of VCA/IgA and EA/IgA were 1:76.86 and 1:6.49 when NPC was diagnosed, which descended quickly after radiotherapy and, in 4 years, approached the average titer of VCA/IgA positive population.</p><p><b>CONCLUSION</b>VCA/IgA titer rises uninterruptedly 3 years before NPC is diagnosed pathologically in most patients but their EA/IgA titer rises slowly. The detection of VCA/IgA titer can be used to find early NPC, whereas EA/IgA can not. The pre-clinical phase of NPC is 3 years according to this dynamic study.</p>
