ABSTRACT
<p><b>OBJECTIVE</b>To determine the reversal effect of aloe emodin liposomes (AE-L) on cisplatin resistance human lung adenocarcinoma cell line A549/DDP.</p><p><b>METHOD</b>The un-cytotoxic and cytotoxic concentration of AE-L, and un-cytotoxic concentration of E-L were determined by MTT. The sensitivity of cisplatin were determined by MTT assay in above 3 groups. The intracellular concentration of cisplatin was detected by inductively coupled plasma mass spectrometry (ICP-MS).</p><p><b>RESULT</b>The maximum non-toxic concentration group of AE-L (2.0 mg x L(-1)) increased the sensitivity of cisplatin in A549/DDP, decreased IC50 of cisplatin in A549/DDP from 16.81 mg x L(-1) to 5.86 mg x L(-1), and the hyp-cytotoxic concentration (7.0 mg x L(-1) ) group's IC50 decreased to 4.34 mg x L(-1); AE-L groups significantly increased intracellular concentration of cisplatin in A549/DDP cells.</p><p><b>CONCLUSION</b>The results showed that aloe emodin can reverse multidrug resistance (MDR) of A549/DDP cells and the mechanism might be associated with the increase of intracellular concentration of cisplatin.</p>
