Polysaccharides of Dendrobium officinale Kimura & Migo protect gastric mucosal cell against oxidative damage-induced apoptosis in vitro and in vivo.
Dendrobium officinale Kimura & Migo (DO) is a valuable Traditional Chinese Medicine to nourish stomach, in which polysaccharides are identified as active ingredients. However, limited scientific evidences have been reported on the gastroprotective efficacy of DO. The aim of the current study was to investigate the protective effects and underlying mechanism of polysaccharides from DO(DOP) on gastric mucosal injury. For in vitro study, HFE145 cells were pretreated with DOP before induction of cell apoptosis by H H The present study was the first one to demonstrate the gastroprotective effect of DOP through inhibiting oxidative stress-induced apoptosis. This study provided a solid evidence for the potential use of DO as a therapy or health supplement for gastric mucosal diseases.
