RESUMO
Objective To investigate whether there is prethrombotic state in acute viral encephalitis.Methods Von willebrand factors (VWF),granule membrane protein-140(GMP-140) and D-dimer were measured in 60 children,30 cases of them had mild acute viral encephalitis, and other 30 cases of them had severe acute viral encephalitis.Results The figures mentioned above had marked difference in children with mild acute viral encephalitis during acute and recovery stage compared with controls.Conclusions Testing the expressive rate of GMP-140 on platelet surface,plasma VWF and D-dimer can find the prethrombotic state immediately. GMP-140,VWF and D-dimer in estimating the severe extent of disease and the prognosis play a major role. J Appl Clin Pediatr,2004,19(6):501-503
RESUMO
Objective To study the mutagenic action of antiepileptic drugs(AEDs), and find an effective way to prevent the mutagenesis induced by AEDs,by observing the effects of AEDs on serum folic acid(FA) level and sister chromatid exchange (SCE) frequency in epileptic children.Methods Ninty epileptic children were divided into different groups on the basis of the different drugs they had taken, then detected the two indexes at different time points.Results The serum FA level and SCE frequency of the patients significantly decreased and increased after they took carbamazepine (CBZ) and valproic acid (VPA)respectively. The two indexes went back respectively when supplied with FA.Conclusions Both CBZ and VPA possess mutagenic action, yet nitrazepam does not.FA may help repair the chromosome damage and reduce the mutagenesis effects.
