RESUMO
<p><b>OBJECTIVE</b>We aim to investigate the sonodynamic effect induced by hydroxyl acetylated curcumin (HAC) on THP-1 macrophages.</p><p><b>METHODS</b>THP-1 derived macrophages (1 x 10(5) per milliliter) were cultured with HAC at a concentration of 5 µg/mL for 4 h and then exposed to pulse ultrasound treatment (0.5 W/cm2) for 5 min. Six hours later, cell viability analysis was performed with CCK-8 assay, apoptosis and necrosis analysis were detected with Annexin V/PI staining by flow cytometery.</p><p><b>RESULTS</b>The cell viability of THP-1 macrophage decreased significantly in the group treated with the combination of HAC and ultrasound (P < 0.01), and HAC-SDT induced both apoptosis and necrosis in THP-1 macrophages, the apoptotic rate was higher than the necrotic rate with appropriate conditions, the maximum apoptosis/necrosis ratio was detected in sonodynamic therapy (SDT) group (P < 0.01).</p><p><b>CONCLUSION</b>hAC-SDT was effective to induce THP-1 macrophages apoptosis.</p>
