Ethyl Acetate Soluble Fraction of Cnidium officinale MAKINO Inhibits Neuronal Cell Death by Reduction of Excessive Nitric Oxide Production in Lipopolysaccharide-Treated Rat Hippocampal Slice Cultures and Microglia Cells

[摘要] References(13)Cited-By(10)In the present work, we found that the ethyl acetate-soluble fraction of Cnidium officinale MAKINO (COEA) decreased nitric oxide (NO) production in the lipopolysaccharide (LPS)-stimulated BV-2 and primary microglia and suppressed expression of inducible nitric oxide synthase (iNOS) in BV-2 cells with the same pattern of NO production. In addition, we showed that excessive NO production played an important role in neuronal cell death in LPS-treated rat hippocampal slice cultures. Our data suggest that the COEA inhibits neuronal cell death by reduction of excessive NO production in LPS-treated rat hippocampal slice cultures. The ethyl acetate-soluble fraction of C. officinale reduced propidium iodide uptake and NO production in cultured media at the same time.
