Non-steroidal anti-inflammatory drugs (NSAIDs) can result in peptic ulcer disease (PUD) which is a common condition worldwide. The aim of this study was to evaluate the antiulcer properties of (1-(4-hydroxy-phenyl)-3-m-tolyl-propenone) (HPTP) chalcone in rats using indomethacin as ulcerogenic agent.
Antrodia camphorata is a parasitic fungus from Taiwan, it has been documented to possess a variety of pharmacological and biological activities. The present study was undertaken to evaluate the potential of Antrodia camphorata ethanol extract to accelerate the rate of wound healing closure and histology of wound area in experimental rats. The safety of Antrodia camphorata was determined in vivo by the acute toxicity test and in vitro by fibroblast cell proliferation assay. The scratch assay was used to evaluate the in vitro wound healing in fibroblast cells and the excision model of wound healing was tested in vivo using four groups of adult Sprague Dawley rats. Our results showed that wound treated with Antrodia camphorata extract and intrasite gel significantly accelerates the rate of wound healing closure than those treated with the vehicle. Wounds dressed with Antrodia camphorata extract showed remarkably less scar width at wound closure and granulation tissue contained less inflammatory cell and more fibroblast compared to wounds treated with the vehicle. Masson's trichrom stain showed granulation tissue containing more collagen and less inflammatory cell in Antrodia camphorata treated wounds. In conclusion, Antrodia camphorata extract significantly enhanced the rate of the wound enclosure in rats and promotes the in vitro healing through fibroblast cell proliferation.
