摘要
目的对紫杉醇-PECT温敏型可注射原位凝胶进行药效学评价。方法建立小鼠肿瘤EAC实体瘤动物模型,分别植入空白凝胶材料PECT(实验1)、肿瘤组织旁及肿瘤组织中植入载药凝胶材料(试验2、3)。以肿瘤生长速率、抑制率、动物体质量增长率为评价指标。结果接受空白凝胶材料植入动物的肿瘤生长抑制率为-3.94%~8.91%;瘤旁植入载药凝胶10 mg/kg,肿瘤生长抑制率为56.62%(P<0.05),效果优于同等剂量静脉注射给药组的2.99%(P>0.1);相同剂量下瘤内植入,肿瘤生长抑制率为38.16%(P<0.05),与同等剂量静脉注射效果相当(25.49%,P>0.1)。结论 PECT凝胶材料原位植入对肿瘤生长没有影响,紫杉醇-PECT载药材料植入给药与注射剂相比能够显著提高疗效,降低毒性反应。
Objective To pharmacodynamily evaluate Taxol - PECT temperature sensitive injectable in situ gel. Methods Estab-lished EAC solid tumor animal model. The blank gel material PECT( experiment 1 ) , and drug-loaded gel materials were implan-ted into the tissue around tumor and tumor lissue (experiment 2~3). The tumor growth rate, inhibition rate, animal growth rate were observed as the evaluation indexs. Results Blank gel materials implanted in animal tumor growth inhibition rate - 3.94% to 8.91%; Tumor adjacent to implantable drug- loaded gel 10mg/kg, tumor growth inhibition rate was 56.62% (P 〈0.05),its effect is better than the same dose intravenous injection group 2.99% ( P 〉 0. 1 ). The same dose of intratumoral implantation, tumor growth inhibition rate was 38.16% ( P 〈 0.05 ) , with the same dose intravenous effect ( 25.49% , P 〉 0.1 ). Conclusion - PECT gel material in situ implantation on tumor growth can not be affected. Taxol - PECT drug carrier material implant delivery and injection can improve the efficacy comparison, reducing the toxic reaction.
