摘要(Abstract):

[Objectives] This study aimed to investigate the anti-inflammatory effects of Baeckea frutescence L.in vitro and in vivo.[Methods]The anti-inflammatory activity of B.frutescence was measured by mouse peritoneal capillary permeability test,mouse auricle swelling test and rat cotton granuloma test.The RAW264.7 macrophage model was stimulated by lipopolysaccharide(LPS),and the effects of B.frutescence on tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6) were detected by enzyme-linked immunosorbent assay(ELISA),and the relative expression of inducible nitric oxide synthase(i NOS) and cyclooxygenase-2(COX-2) proteins was detected by Western blot.Thus,the in vitro anti-inflammatory activity of B.frutescence was studied.[Results] B.frutescence significantly inhibited mouse peritoneal capillary permeability,inhibited xylene-induced mouse auricle swelling and rat cotton granuloma,significantly inhibited TNF-α and IL-6 levels,and down-regulated the expression of i NOS and COX-2 proteins in cells.[Conclusions]B.frutescence showed good anti-inflammatory activity both in vitro and in vivo,and the mechanism may be related to the release inhibition of inflammatory factors TNF-α and the regulation of COX-2.
