Pyrogallol, a potent anti-psoriatic drug, produces toxicity due to its ability to generate free radicals, besides its beneficial effects. Oxidative stress is implicated in pyrogallol-mediated toxicity in general and hepatotoxicity in particular. Naturally occurring antioxidants including, resveratrol and silymarin have

Quorum sensing, bacterial cell-to-cell communication with small signal molecules, controls the virulence of many pathogens. In contrast to other vibrios, neither the VanI/VanR acylhomoserine lactone quorum sensing system, nor the three-channel quorum sensing system affects virulence of the economically important
