【摘要】 目的　通过检测外周血淋巴细胞姊妹染色体交换 (SCE)频率及血清叶酸 (FA)水平 ,研究抗癫药物 (AEDs)对机体的诱变作用及其对FA代谢的影响 ,寻求抗诱变作用的途径。方法　选择癫患儿 90例 ,依据应用AEDs不同分组 ,检测各组用药前后SCE频率及FA水平 ,以及补充FA后两指标变化。结果　服用卡马西平 (CBZ)和丙戊酸钠 (VPA)的癫患儿 ,服药后较服药前血清FA明显降低 ,SCE频率显著升高 ,而补充服用FA后两指标有明显改善。结论　CBZ、VPA对小儿机体具有诱变作用 ,但硝基安定无明显诱变作用。FA能够减轻AEDs对机体的诱变作用。更多还原

【Abstract】 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.更多还原
