Propolis is a bee product used since ancient times due to its diverse biological applications. We aimed investigate the antioxidant and anti-inflammatory action of Brazilian propolis in THP-1 cells stimulated with 1‐fluoro‐2,4‐dinitrobenzene (DNFB) or lipopolysaccharide (LPS). Cell viability was assessed by resazurin assay, activity evaluated DPPH superoxide dismutase (SOD) 1 2 colorimetric ass...

To study the role of the redox state regulator glutathione (GSH) in bacterial lipopolysaccharide (LPS)-induced anorexia we measured total reduced GSH (trGSH) in liver, serum and brain in response to intraperitoneal (ip) lipopolysaccharide (LPS, 4 microg/mouse) injection in LPS-naïve and LPS-pretreated (4 microg/mouse given 3 days earlier) mice. LPS reduced food intake in LPS-naïve mice and LPS ...

abstract   the mutagenic and immunosuppressory effects of cyclophosphamide (cyp) are still the primary limitation to wider application for treating a variety of human malignancies. on the one hand, cyp treatment predisposes transplant recipients and cancer patients to risk of bacterial, fungal, and viral infections, in the other word the, lipopolysaccharide (lps), an endotoxin found in cell wal...

Background: The brain in exposure to irritating factors may lead to production of some chemical factors and proinflammatory cytokines and neuroinflammation. Over time, the chronic neuroinflammation will cause some cognitive disorders and neurodegenerative diseases. The present study studied the effect of acetyl L -carnitine on cognitive and cellular disorders derived from lipopolysaccharide (LP...
