BACKGROUND Melanogenesis, a process producing the pigment melanin in human skin, eyes and hair, is a major physiological response against various environmental stresses, in particular exposure to ultraviolet radiation, and its pathway is regulated by a key enzyme, tyrosinase. In this study, we

Mao is one component of various traditional herbal medicines. We examined the effects of Mao on an acute liver failure model treated with d-galactosamine (GalN) and lipopolysaccharide (LPS). The lethality of mice administrated Mao with GalN/LPS was significantly decreased compared with that in mice

It is generally accepted that the primary pharmacological activities and adverse effects of Ephedra Herb are caused by ephedrine alkaloids. Interestingly, our research shows that Ephedra Herb also has ephedrine alkaloid-independent pharmacological actions, such as c-MET inhibitory activity. This
