LPS intoxication

Lipopolysaccharide (LPS) endotoxins are characteristic Gram-negative outer-cell components which are produced by many cyanobacteria. Although LPS have been characterized and found to be toxic to laboratory animals after isolation from cyanobacteria, their toxicity to rodents is less potent than the endotoxins of enteric pathogens such as Salmonella Typical symptoms of animals suffering from LPS intoxication include vomiting, diarrhoea, weakness and death after hours rather than minutes. 

Curcumin (9) is an arylheptanoid isolated from turmeric, the rhizome of Curcuma longa L. Turmeric has been used as a remedy for inflammatory in Asia for centuries. There are a number of reports supporting an anti-inflammatory effect of curcumin. Its hepatoprotective activity against inflammatory liver injury was also demonstrated in a recent study [105], where pretreatment with curcumin (50 mg/kg, p.o.) significantly inhibited the elevation of serum transaminase activities after intoxication with D-GalN and LPS in mice. The hepatoprotective effect is presumably...
