Endotoxin molecules in lipopolysaccharides are among most important molecules that initiate a cascade of events in sepsis/endotoxemia. Lipopolysaccharide exposure may result in strong immune responses, disrupt the intracellular oxidant/antioxidant balance, and cause excessive reactive oxygen species generation. The purpose of the study was to examine if reduced glutathione (GSH) has a protective role against lipopolysaccharides. The effects of lipopolysaccharide (LPS) or GSH alone or in combination on the levels of the plasma antioxidant system, NO, and liver HSP70 were investigated. A total of 100 Swiss albino mice were divided into 4 groups as Group I (control), Group II (20 μg/kg …

The main purpose of this study was to investigate the effects of nutrient and macronutrient stress on complex variations in the phenolic profile and antioxidant status of Bellis perennis L. callus cultures. To obtain stress conditions, callus cultures were grown under insufficient nutrient conditions (different strengths of MS medium) or under conditions of limiting calcium (-Ca), magnesium (-Mg), or both (-Ca & -Mg). Phenolic content of callus cultures obtained from different stress treatments was detected quantitatively by LC-ESI-MS/MS analysis. The major compound was chlorogenic acid in all treatments. The accumulation of hesperidin, rutin hydrate, and chlorogenic acid was significantly induced …
