Distribution and anti-tumor efficacy of PLD, and the structure and function of the tumor vasculature were evaluated using various techniques.RESULTS: TanⅡ A significantly reduced the micro-vessel density(MVD). After Tan vascular walls were betteⅡr s A treatment,the tumor tructured, as the increased coverage of the pericytes and the promoted contact of the basement membrane and endothelial cell. Functional tests showed that tumor hypoxia was improved and the exudation amount of Evans blue in the parenchyma of the tumor decreased. In addition, mice treated with TanA had greater PLD penetration distance intratumoⅡrally. Furthermore, combined therapy of Tanibited tumor growth.ⅡA and PLD significantly inhCONCLUSION: This study suggests that Tanasculature andⅡ h A helps normalizing the tumor vas therapeutic potential in increasing the distribution of chemotherapy drug in the tumor.展开更多
