PURPOSE
Prostaglandins(PGs) are known to produce a remarkably broad spectrum of effects that embraces practically every biological function, and has a particular physiological role in the central nervous system. Significant increases of PGs levels are seen in certain diseases, such as febrile infection, stroke, schizophrenia, and epilepsy. Prostaglandin is also increased in a response to rising body temperature, and prostaglandin E-2(PGE-2) in lumber cerebrospinal fluid is also increased in febrile convulsion. Intracerebroventricular injection of PGE produces a rise in body temperature and also antagonizes convulsions induced by pentylenetetrazole, penicillin, electric shock. Therefore we studied PGE-2 levels in cerebrospinal fluid of afebrile children, children with febrile convulsion, and febrile children without convulsion. METHODS: The subjects comprised 57 cases with febrile convulsion, 24 cases of afebrile diseases and 9 febrile children without convulsion. All patients were undergoing lumbar puncture and PGE-2 levels in CSF were determined by highly specific radio-immunoassay(Prostaglandin E2 [125I] assay system, Biotra Assays, Amersham Inc.). RESULTS: 1) The CSF PGE-2 levels were significantly higher in children with febrile convulsion(147.3+/-79.3pg/ml) than those in febrile children without convulsion(72.4+/-75.4pg/ml) and afebrile children(19.2+/-28.4pg/ml)(p<0.05). 2) There were no statistical significances of the CSF PGE-2 levels between age and fever in both groups. 3) The CSF PGE-2 levels within 4 hours(176.5+/-65.7pg/m1) after convulsions were significantly higher than those 4 hours after convulsion(93.3+/-74.9pg/ml). CONCLUSION: The CSF PGE-2 levels were significantly higher in children with febrile convulsion than those in febrile children without convulsion and those in afebrile child ran. The CSF PGE-2 levels within 4 hours after convulsion were significantly higher than those 4 hours after convulsion. |
