评价了目前选择性肝动脉灌注治疗模型在短期药代动力学实验中的适用性。该制剂包括经大鼠胃十二指肠动脉选择性插管肝总动脉。注射放射性微球以确定肝脏或肝外的灌注部位。放射性微球测定肝动脉流量和心输出量。我们的数据表明,在高流速(2ml/min)下,由于逆流,药物会发生显著的损失。对模型进行修改,包括临时阻断肝近端动脉,可确保95%以上的药物在肝脏内释放。此外,临时肝动脉阻断不改变心输出量或肝动脉阻断不改变心输出量或肝动脉血流量。同步暂时性肝动脉阻断的大鼠选择性肝动脉灌注是一种适合短期药代动力学研究的模型。
The current model for selective hepatic arterial infusion therapy was evaluated for its suitability for short-term pharmacokinetic experiments. This preparation consists of selective cannulation of the common hepatic artery via the gastroduodenal artery of the rat. Radioactive microspheres were injected to determine hepatic or extrahepatic sites of perfusion. Radioactive microsphere determination of hepatic arterial flow and cardiac output were also performed. Our data indicate that at high flow rates (2 ml/min), significant loss of drug would occur due to retrograde flow. Modification of the model to include temporary proximal hepatic artery occlusion ensures hepatic delivery of greater than 95% of drug. Furthermore, temporary hepatic artery occlusion does not alter cardiac output or hepatic artery occlusion does not alter cardiac output or hepatic arterial blood flow. Selective hepatic arterial infusion in rats with synchronous temporary hepatic artery occlusion is an adequate model for short-term pharmacokinetic studies.
