| 摘要 | [Objectives] To study the anti-inflammatory effect of Elephantopus scaber L. extract on acute pleurisy induced by carrageenan in rats, and to explore its anti-inflammatory mechanism. [Methods] The active sites of E. scaber L. were extracted by ethanol reflux method. The extracts of different concentrations of E. scaber L. were used as the study object, and dexamethasone was used as the positive control drug. The anti-inflammatory effects of E. scaber L. extracts were studied by measuring the levels of malondialdehyde (MDA), prostaglandin E2 (PGE2), tumor necrosis factor (TNF-α), interleukin-1β(IL-1β) in pleural fluid and serum nitric oxide (NO), MDA, PEG2, TNF-α, IL-1β in rats with acute pleurisy induced by carrageenan. [Results] E. scaber L. extracts in three doses could reduce the levels of inflammatory factors in pleural fluid and serum, and inhibit acute pleurisy in rats. It was speculated that the anti-inflammatory mechanism was related to the inhibition of the release of inflammatory factors and the antioxidant effect of extracts of three doses of E. scaber L. [Conclusions] This experiment provides a basis for the development and application of E. scaber L. |
