Research Article: Ethanol extract of Paridis rhizoma attenuates carrageenan-induced paw swelling in rats by inhibiting the production of inflammatory factors
Abstract:
Inflammation has been identified as a key factor contributing to the development of numerous diseases. Several anti-inflammatory drugs have been developed to treat inflammation-related diseases. However, some of such drugs are associated with varying degrees of side effects. Therefore, it is imperative to develop new anti-inflammatory drugs with reducing side effects for the treatment of inflammation-related diseases. Natural anti-inflammatory drugs have emerged as an important area of research in recent years. The study was to determine the anti-inflammatory mechanism of Paridis rhizoma extract (PRE) in rat models of acute inflammation induced by carrageenan and RAW264.7 cells models induced by lipopolysaccharide (LPS).
Introduction:
Inflammation is an important immunological response induced by harmful stimuli such as pathogens, toxins, injury, infection, and/or irritation [1]. Therefore, it is an important defensive mechanism in the body [2]. Inflammatory processes are driven by several factors including white blood cells, plasma, and fluid at the site of inflammation. Changes in levels of molecules released by immune defence cells and other signalling molecules such as histamine, prostaglandins, leukotrienes, oxygen- and nitrogen-derived…
