采用液体闪烁计数技术研究厂氖标记米托惠醌聚氰基丙烯酸正丁酯毫微球（￣（３）Ｈ－ＤＨＡＱ－ＰＢＣＡ－ＮＳ）在常位及异位（腋下）裸小鼠人肝癌模型体内各脏器、肌肉、肝常位肿瘤组织和腋下肿瘤组织中的分布。证明该制剂具有良好的肝靶向作用，肝脏中的含量为体内总药量的７１．３１±１０．４９％（ｎ＝５）。并发现其在常位肿瘤组织中的含量高于肝组织中的含量，腋下肿瘤组织中的含量高于腋下肌肉组织中的含量，但均无显著性差异。为该制剂的进一步研究提供了一定的科学依据。 We used liquid scintillation counting technique to study the effect of neon labeled mitochondria-n-butylmethacrylate n-butylnitrate (~ (3) H-DHAQ-PBCA-NS) on eutopic and ectopic Distribution of HCC Models in Various Organ, Muscle, Lymph Node Tumor Tissues and Axillary Tumor Tissues. It is proved that the preparation has good liver targeting effect, and the content in the liver is 71.31 ± 10.49% (n = 5) of the total amount in the body. And found that its content in the standing tumor tissue higher than the content of liver tissue, underarm tumor tissue content higher than the armpit muscle tissue content, but no significant difference. This study provides a scientific basis for further research.
