[ABSTRACT] Escin, as an internally applied anti-inflammatory agent, has been widely used in the treatment of inflammation and edema resulting from trauma or operation in the clinic. However, the effect of its external use on cutaneous inflammation and edema remains unexplored. In the present study, the anti-inflammatory and anti-edematous effects of external use of escin were studied in carrageenan-induced paw edema and histamine-induced capillary permeability in rats, paraxylene-induced ear swelling in mice, and cotton pellet-induced granuloma in rats. Effects of external use of escin gel on prostaglandin E2 (PGE2), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β) were determined by ELISA ...

[ELISA for PGE2, TNF-α, and IL-1β analyses] The levels of PGE2, TNF-α and IL-1β were determined according to LI’s method  [1] . In brief, the tissue samples were obtained from paw edema and capillary permeability models,followed by homogenizing with ice-cold saline for a 10%(W/V) homogenate. The ELISA kits of PGE2 (JianglaiBio, Shanghai, China[1]), TNF-α (Lianke Bio, Wuhan, China) and IL-1β (Lianke Bio, Wuhan, China) were use, according to manufacturer’s instructions.
