| 摘 要： | 目的 :探讨不同剂量砷对大鼠大脑皮层乙酰胆碱脂酶 (ACh E)的影响。方法 :以剂量递增法建立染砷大鼠动物模型。1 2周后 ,测定不同剂量砷对大鼠大脑皮层乙酰胆碱脂酶 (ACh E)的影响。结果 :不同剂量染砷组间大鼠大脑皮层乙酰胆碱脂酶 (ACh E)活性有显著性差别 (P<0 .0 5 )。随剂增加 ACh E值降低 (P<0 .0 5 ) ,呈剂量—效应关系。低剂量组与正常对照组相比 ,乙酰胆碱脂酶活性无显著性差别 (P>0 .0 5 )。结论 :随染砷剂量增加 ,大鼠大脑皮层 ACh E活性降低 ,呈剂量—效应关系。

| Abstract: | Objective:To study the effect of difference dose Arsenite on acetyicholinease of cerebral cortex.Methord:Animal model were created by means of increasing dose,After 12 week,the activity of AChE in cerebral cortex of four group rats were measured.Results:AChE activity of cerebral cortex in rat was significantly different in the differert dose groups (P<0 05).With the rise of dose,AChE level in cerebral cortex was markedly lower (P<0 05).and was in a dose-effect manner.AChE activity was not significantly different between low-does and high-dose group(P>0 05)?Conclusion:Level of AChE of cerebral cortex could be affected by Arsenity.The change was in a dose-effect manner. |
