Objective: To determine both Neuron-Specific Enolase (NSE), Nitric Oxide (NO)/Nitric Oxide Synthase (NOS) in cerebrospinal fluid (CSF), their regular changing pattern, relationship, and influence on happening, developing and recovering of various nervous system’s diseases were investigated and their clinical values were illustrated.

Methods: In 115 cases with nervous system’ s diseases - include 18 Guillain - Barre Syndrome (GBS), 30 epilepsy, 28 bacterial meningitis and 40 acute viral encephalitis. 20 age - matched children with normal neurologic development as control group. All CSF were collected by sterilized, closed method within 24 hour after entrance. NSE and NO/NOS levels in CSF were Studied by ELISA enzymo-immunoussay and Griess chemical colorimetric methods, respectively.

Results:  1. NSE , NO/NOS levels of CSF were significantly higher in all groups (5.309±0.59 ~ 11.91±4.28ng/ml , 2.45±0.58 ~6.89±0.89umol/ml , 4.44±0.89 ~ 12.60±2.10umol/ml.min, respectively ) than that for the control group (4.11±0.431ng/ml, 1.90±0.41umol/ml, 2.82±0.65umol/ml.min). 2. The CSF-NSE levels was at the highest level in group of bacterial meningitis (11.91±4.28ng/ml), and NO/NOS levels of CSF were at the highest level in group of epilepsy (6.89±0.89umol/ml, 12.6±2.10umol/ml.min). 3. NSE to NO, NSE to NOS and NO to NOS of CSF changes were very correlated (r=0.57 ~ 0.78, p<0.05 ~ 0.01) in all groups of subject.

Conclusion: The results as above showed: 1. NSE, NO/NOS Levels of CSF elevated in varying degrees with nervous system ‘s diseases, to illustrate definite neuronal and glial cell damage to certain extent in these diseases of GBS, epilepsy, bacterial meningitis and acute viral encephalitis. 2. As active biological mark---both NSE and NO/NOS of CSF changes were very correlate (r=0.57 ~ 0.78, p<0.05 ~ 0.01), to show that they all giving play an important roles in diseases of happening, developing course. 3. NSE Levels of both bacterial meningitis and epilepsy were at the highest level in all groups, and NO/NOS also were at the highest level, to state clearly neuronal and glial cell damage seriously, NO/NOS might become more serious these damages through cellulotoxic. In GBS, mainly due to axon and myelin of peripheric nervous fiber’s immunity damages, and neuronal damage were not serious, so NSE were elevated lowest, NO/NOS expressivity were also lowest. As conclusion, NSE, NO/NOS can be regarded as marker of importance and sensitivity in neuronal cell damages, for judging happening, developing and recovering of nervous system’s disease with definite clinical values.
