RESUMO

Atractylodes japonica has traditionally been used for the treatment of pain and arthritis. The effect of Atractylodes japonica against lipopolysaccharide-induced inflammation was investigated using reverse transcription-polymerase chain reaction (RT-PCR), nitric oxide detection, and prostaglandin E2 (PGE2) immunoassay in mouse RAW 264.7 macrophages. The aqueous extract of Atractylodes japonica suppressed nitric oxide production and PGE2 synthesis by inhibition of the lipopolysaccharide-stimulated enhancement of inducible nitric oxide synthase and cyclooxygenase-2 mRNAs expressions in RAW 264.7 macrophages. These results suggest that Atractylodes japonica exerts anti-inflammatory and analgesic effects probably by suppression of the inducible nitric oxide synthase and cyclooxygenase-2 expressions.

RESUMO

Traditionally, Puerariae radix had been used for the treatment of alcohol-related problems. In this study, effects of Puerariae radix on cell proliferation and nitric oxide synthase expression in the dentate gyrus of alcohol-intoxicated Sprague-Dawley rats were investigated via 5-bromo-2'-deoxyuridine (BrdU) immunohistochemistry and nicotinamide adenine dinucleotide phosphate-diaphorase (NADPH-d) histochemistry. Alcohol administration was shown to inhibit the numbers of both BrdU-positive and NADPH-d-positive cells, while Puerariae radix treatment was shown to increase those numbers. It is possible that nitric oxide, which might play an important role in the regulation of cell proliferation, is a major target of the toxic effects of alcohol.
