Effects of aqueous extract of Notobasis syriaca on lipopolysaccharide-induced inflammation in rats

Objective: To investigate the effects of a dry aqueous extract of Notobasis syriaca (N. syriaca) on lipopolysaccharide (LPS)-induced inflammation in rats. Methods: Rats were fed the dried extract [500 mg/(kgod)] for three consecutive days and then were intraperitoneally injected with LPS (1 mg/kg)....

Description
Summary:Objective: To investigate the effects of a dry aqueous extract of Notobasis syriaca (N. syriaca) on lipopolysaccharide (LPS)-induced inflammation in rats. Methods: Rats were fed the dried extract [500 mg/(kgod)] for three consecutive days and then were intraperitoneally injected with LPS (1 mg/kg). Two hours after LPS injection, rats were sacrificed and blood and brain regions were collected. Inflammatory mediators’ levels in plasma and homogenates of brain regions were determined by ELISA. Results: Pretreatment with the N. syriaca extract resulted in significant anti-inflammatory effects (P<0.05), including: i) attenuated LPS-induced hypothermia; ii) decreased hypothalamus and hippocampus prostaglandin E2 levels in the LPS- treated rats; and, iii) reduced hypothalamus and hippocampus interleukin-6 and tumor necrosis factor- α levels in the LPS-treated rats. Conclusions: These results suggest that N. syriaca possesses anti-inflammatory properties. Thus, it is possible that long-term consumption of this plant may result in beneficial pharmacological effects.
