Application of pyrrosia lingua aqueous extract in preparation of medicine for preventing and treating radioactive intestinal injury

The invention discloses an application of a pyrrosia lingua aqueous extract in preparation of a medicine for preventing and treating radioactive intestinal injury. Radioactive intestinal injury is a common complication of ionizing radiation, and has main pathological characteristics of intestinal mucosal barrier destruction, excessive release of inflammatory factors, increase of oxidative stress level and hematopoiesis and immune function inhibition. At present, no effective and safe prevention and treatment medicine is available. It is found for the first time that the pyrrosia lingua aqueous extract can inhibit expression (IL-6, TNF-alpha and IL-1beta) of inflammatory factors of radiation-induced MODE-K cells and relieve the oxidative stress level (malondialdehyde (MDA) is reduced, and the content of superoxide dismutase (SOD) and glutathione (GSH) is increased). In animal experiments, the pyrrosia lingua aqueous extract can reduce the levels of TNF-alpha and IL-1beta inflammatory factors in serum of irradiated mice and improve oxidative stress disorders such as MDA increase, SOD and GSH decrease and the like; the reduction of leukocytes and lymphocytes is relieved; the length of intestinal villus is promoted and recovered; the proportion of Ki67 positive cells in a crypt region is increased, so that the regeneration capacity of intestinal epithelial cells is enhanced. The pyrrosia lingua aqueous extract disclosed by the invention provides an experimental basis and an application prospect for developing a novel medicine for preventing and treating the radioactive intestinal injury.
