1、介入放射学杂志2013年11月第22卷第11期JInterventRadiol2013,Vo1.22,No.11—931一·实验研究Experimentalresearch·兔肝脏、肌肉、皮下VX2肿瘤模型的建立和对比研究魏强,方亮,杨继金,霍宁宁,吕虎,熊源长,江旭,李慧【摘要】目的通过对肝脏、肌肉及皮下不同部位兔vx。肿瘤模型的建立和比较,寻求更适合于肿瘤经皮介入治疗的荷瘤动物模型。方法将54只新西兰白兔按vx肿瘤接种部位不同随机分为肝脏组、肌肉组和皮下组,每组18只。三组动物术后12、16、20d均进行CT灌注扫描,测量肿瘤大小,每次各组分别处死6只兔进行
2、病理观察,并对三组模型的建模手术时间、肿瘤体积及并发症等情况进行比较。结果皮下组肿瘤生长最慢,肌肉组其次,肝脏组生长最快,组间差异有统计学意义(P<0.05)。接种第12天,肝脏组肿块长径已约1cm,而皮下组则需20d肿块长径才达1cm左右,肌肉组肿块生长速度介于二者之间。三组建模所用时间分别为肝脏组(5.54±0.51)min,肌肉组(1.024-0.20)rain,皮下组(0.98±0.21)min,肝脏组明显较长。除了肝脏组出现腹水、肝内转移及腹壁种植外,皮下组、肌肉组均无明显影响模型的情况。结论与肝脏和皮下建模相比,兔肌肉内VX肿瘤模型具有操作简单,成瘤
3、稳定,肿瘤生长速度适中的优点,更适合作为兔VX:瘤的经皮介人治疗模型。【关键词】肿瘤;肝脏;肌肉;VX一2;动物模型中图分类号:R735.7文献标志码:B文章编号:1008—794X(2013)一11-0931-05Theestablishmentofrabbitmodelswithintrahepatic。intra—muscularandsubcutaneousVX一2tumor:acomparisonstudyWEIQiang,FANGLiang,YANG一jin,HUONtng—ning,LVHu,XIONGYuan—chang,JIANGXu,LIHu
