This invention belongs to the field of
biomedical technology, specifically disclosing the application of oleylethanolamine in the preparation of drugs for preventing and treating intestinal
radiation damage, and a
drug for preventing and treating intestinal
radiation damage. This invention utilizes a small intestinal
organoid model and employs high-content screening technology to screen for oleylethanolamine, which can
resist radiation damage to intestinal organoids, promote post-radiation regeneration and repair of organoids, promote
stem cell proliferation and regeneration, improve post-
irradiation survival rate, and alleviate morphological changes in the intestine caused by
radiation damage. When oleylethanolamine is prepared into a
drug and administered, it can improve intestinal lesions caused by
radiation damage, protect stem cells from post-damage regeneration and repair, restore the self-renewal and differentiation functions of stem cells, enable stem cells to self-renew and replenish new stem cells, and differentiate into different types of epithelial cells to protect villous structures, thereby alleviating intestinal damage symptoms.
