The invention discloses application of a
mast cell inhibitor in prevention and treatment of brain injury after
hair growth matrix bleeding, and relates to the technical field of biological medicines. The
mast cell inhibitor is a
mast cell stabilizer and plays a role by inhibiting
degranulation of mast cells; the
mast cell stabilizer is
sodium cromoglycate or pharmaceutically acceptable salt, ester, solvate or
prodrug thereof; the
medicine is used for preventing and / or treating brain injury after newborn
hair growth matrix bleeding, wherein the brain injury comprises one or more of
neuroinflammation,
lymphatic system dysfunction, intracerebral toxic
metabolite accumulation,
hematoma enlargement and neurobehavioral function impairment. Early activation of mast cells is used as a key intervention target spot for preventing and treating the brain injury after the newborn
hair growth matrix bleeding; different from a traditional method for bleeding or wide later-stage
inflammation, the method focuses on the extremely early hub link of the injury
cascade reaction, and a novel prophylactic or ultra-early therapeutic thought is provided.
