ABSTRACT
<p><b>OBJECTIVE</b>To investigate the feasibility of plasmid nm23-h1 transfection on high metastatic potential adnoid cystic carcinoma (ACC-M) cell line mediated by cationic lipid.</p><p><b>METHODS</b>ACC-M cell were implanted in the maxillofacial region in each of 40 BALB/c nude mice. After the tumor growth to 1 cm in diameter, 0.1 ml Lipofctamine-nm23-hl plasmid complex were injected intratumorally in 10 mice, 3 days after the first injection, 10 mices injected for twice, 10 mice as plamid-blank control, another 10 mice were injected 0.2 ml complex, 2, 3, 7days after the injection, the mice were killed and the specimen for HE and immunohistological chemistry study.</p><p><b>RESULTS</b>nm23-h1 expression initiated in the tumor cells 3 days after the complex injection, 7 days later, the expression level increased accompanying with extracellular matrix increase, twice injection and multiple channel injection would gain better nm23-h1 expression than once injection and single-channel injection respectively.</p><p><b>CONCLUSION</b>Cationic lipid mediated nm23-h1 plamid transfecting adnoid cystic carcinoma can gain small range positive expression, but the results give little prospect for further clinical treatment in such a manner.</p>
