Changes of Cerebrospinal Fluid ?-Endorphin and C-Reactive Protein in Children with Central Nervous System Infection / 实用儿科临床杂志

ABSTRACT

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.
