  • Publication number: 20240000788
    Abstract: Use of pentoxifylline (PTX) in preparation of a medicament for repairing endothelial glycocalyx damage, and belongs to the technical field of medicine. A chlorine-induced endothelial glycocalyx damage model is established. After the endothelial glycocalyx damage model is successfully established, the PTX is intraperitoneally injected into a rat with endothelial glycocalyx damage. The result shows that the PTX effectively repairs shedding of glycosaminoglycans and syndecans in the endothelial glycocalyx damage and significantly downregulates the expression of inflammatory factors including tumor necrosis factor alpha (TNF-?), interleukin-6 (IL-6), and matrix metallopeptidase 13 (MMP-13). Therefore, the PTX can effectively repair the endothelial glycocalyx damage, providing a new theoretical basis for repairing the endothelial glycocalyx damage. Furthermore, with high safety, the PTX has the prospect of being developed into the medicament for repairing the endothelial glycocalyx damage.
