title: Schisandra chinensis prevents hepatic lipid peroxidation and oxidative stress in rats subjected to heat environmental stress.
abstract: Increases in temperature cause a proliferation of heat-stress-related disorders by disrupting the body's homeostasis system, particularly when excessive levels of reactive oxygen species disrupt the balance of antioxidant defence systems. Thus, controlling oxidative stress is important for the regulation of body homeostasis. Schisandra chinensis (SC) has a potential effect on antioxidants and is resistant to high temperatures. However, the mechanism of SC during heat stress is unclear. Therefore, we evaluated the effect of SC on heat stress by performing several bioactive genetic assays on Sprague Dawley (SD) rats. The results demonstrated that heat stress significantly increased in heat-stress-related gene expression whereas it was dramatically reduced in the gene expression of the SC group. The genes related to oxidative stress were also significantly suppressed in the SC group compared with those of the heat stress group. Furthermore, there was a greater decrease in the MDA content of the SD rats in the orally administered SC group than in the heat exposure group. Thus, we demonstrate that SC has a protective effect on heat stress as a result of its strong antioxidant properties and the prevention of lipid peroxidation.
