The Inhibitory Effect of Icariin Nanoparticles on Angiogenesis in Pulmonary Fibrosis.

2021 
This study investigated icariin (ICA) nanoparticles on angiogenesis in rats with pulmonary fibrosis and its mechanism. First, icariin solid nanoliposomes (ICA-SLN) were prepared. The in vitrorelease of icariin nanoparticles was determined using a UV-Vis spectrophotometer, after which the plasma concentration of icariin nanoparticles in rats was determined. The bioavailability of icariin nanoparticles was investigated, and the effect of icariin on angiogenesis of pulmonary fibrosis rats was re-observed. The results showed that the bioavailability of icariin in vivo was enhanced after nanomodification, which indicated that icariin solid nanoliposome was a good choice for oral sustained-release nanocarrier materials. in vivo experiments showed that icariin could significantly inhibit angiogenesis in rats with pulmonary fibrosis, and the inhibitory effect was related to the dose and time of action. Most importantly, this study provides the possibility of icariin as a targeted agent for future-targeted therapy.
