Objective To investigate the effects of triptolide(T10) on expression of inducible nitric oxide synthase(iNOS) and production of nitrogen monoxidum(NO) in microglia cells induced by β-amyloid(Aβ) 1-42.Methods The microglia cells were pretreated with 10-11-10-8 mol / L T10 for 12 h before 10 μmol / L Aβ1-42 were added,and incubated for 12 h together.The production of NO was determined by Griess reaction,and the expression of iNOS was determined by Western blotting.Results Expression of iNOS and production of...
