          摘  要  目的  研究聚乙二醇-(聚乳酸-羟基乙酸)-聚乙二醇三嵌段共聚物-克班宁纳米粒(PELGE-Cre-NPs)在大鼠体内的组织分
          布及组织药动学特征。方法  将 SD 大鼠分为 9 组(每个时间点为 1 组),每组 6 只,雌雄各半。尾静脉注射 PELGE-Cre-NPs(5
          mg/kg)后,分别于5、15、30、60、90、120、180、240、300 min时取各组大鼠心、肝、脾、肺、肾、脑组织适量,以盐酸维拉帕米为内标,采
          用高效液相色谱法测定各组织中克班宁(Cre)的含量,并计算药-时曲线下面积(AUC0-t )、平均滞留时间(MRT0-t )等主要药动学参
          数。结果  给药后5~90 min,Cre在大鼠各组织样品中的含量由高到低依次为肺、肾、脾、肝、脑、心;给药后120~300 min,Cre在大
          鼠各组织样品中的含量由高到低则变为肺、脾、肾、肝、脑、心。Cre在心、肝、脾、肺、肾、脑组织中的AUC0-t分别为(18.86±1.66)、
         (43.36±4.99)、(51.36±5.34)、(81.86±12.34)、(53.31±3.19)、(27.73±4.76) mg·h/L,MRT0-t分别为(1.94±0.12)、(1.97±1.02)、
         (1.98±1.23)、(1.89±0.21)、(1.88±0.06)、(1.85±0.19) h。结论  PELGE-Cre-NPs 在大鼠体内的组织分布以肺组织为主、心组织
          较少,在心、肺、肝组织中的消除较慢。

          ABSTRACT   OBJECTIVE  To study the tissue distribution and pharmacokinetic characteristics of polyethylene glycol-(polylactic

          acid-hydroxyacetic  acid)  -polyethylene  glycol  triblock  copolymer (PELGE)  -crebanine  nanoparticles (PELGE-Cre-NPS)  in  rats.
          METHODS  The  SD  rats  were  divided  into  9  groups (1  group  at  each  time  point),  with  6  rats  in  each  group,half  male  and  half
          female.  After  PELGE-Cre-NPs(5  mg/kg)  was  injected  into  tail  vein  of  rats,  appropriate  amounts  of  heart,  liver,  spleen,  lung,
          kidney and brain tissues were taken at 5, 15, 30, 60, 90, 120, 180, 240 and 300 min, respectively. With verapamil hydrochloride
          as  internal  standard,  the  content  of  crebanine (Cre)  in  each  tissue  was  determined  by  HPLC,  and  the  main  pharmacokinetic
          parameters such as area under the drug-time curve (AUC0-t ) and mean retention time (MRT0-t ) were calculated.RESULTS At 5-90
          min  after  medication,  the  content  of  Cre  in  each  tissue  of  rats  from  large  to  small  was  lung,  kidney,  spleen,  liver,  brain  and
          heart;  at  120-300  min  after  medication,  the  sequence  was  lung,  spleen,  kidney,  liver,  brain  and  heart. AUC0-t  of  Cre  in  heart,
          liver,  spleen,  lung,  kidney  and  brain  were (18.86±1.66), (43.36±4.99), (51.36±5.34), (81.86±12.34), (53.31±3.19)  and
         (27.73±4.76)  mg·h/L,  respectively.  MRT0-t  of  Cre  were (1.94±0.12), (1.97±1.02), (1.98±1.23), (1.89±0.21), (1.88±
          0.06), (1.85±0.19)  h,  respectively.  CONCLUSIONS  PELGE-Cre-NPs  mainly  distribute  in  lung  tissue,  but  less  in  heart  tissue,
                                                             and  the  elimination  of  PELGE-Cre-NPs  in  heart,  lung  and
