摘 要:目的应用纳米活性炭粒吸附阿霉素开展淋巴化疗,观察其在犬体内的药代动力学变化。方法活性炭混悬液2ml与阿霉素5mg混匀后注射于犬胃窦前壁浆膜下,质谱仪测定不同时间点的胃网膜右动脉旁淋巴结、胸导管内淋巴液及血液内阿霉素浓度。结果胃窦前壁浆膜下注射活性炭吸附的阿霉素,立即见注射点周围出现黑色的细淋巴管及黑染的淋巴结,犬胃网膜右动脉旁淋巴结内阿霉素含量在第30分钟时已升高,在第60分钟时达高峰[(84.6±2.0)μg/g组织],持续72h后仍维持于较高水平;犬胸导管内淋巴液阿霉素浓度在第30分钟时达高峰(162.5ng/m1),以后持续缓慢下降,在第6小时时仍可测出淋巴液内有阿霉素的存在;血液中未测出阿霉素的痕迹。绪论应用纳米活性炭粒吸附阿霉素开展淋巴化疗,引流淋巴液、淋巴结内阿霉素含量高、维持时间长。Objective To observe the pharmacokinetics of adriamycin-adsorbing nanometric activated carbon in intralymphatic chemotherapy. Methods Two ml of suspension of activated carbon with the diameter of 21 nm was mixed with adriamycin 5 mg. Eighteen dogs were randomly divided into 6 equal groups. The above mentioned mixture was injected subserosally to the anterior wall of gastric antrum of the dogs. Thirty minutes, 1 h, 2 h, 1 day, and 3 days after the injection the gastroepiploic lymph nodes of the Groups 1 -5 were obtained. And Group 6 underwent extraction of venous blood samples 5, 15, 30, 60, 120, and 240 minutes after the injection and extraction of thoracic duct fluid 5, 15,30, 60, 120,240, and 360 minutes after the injection. The adriamycin concentrations at different time points were determined by mass spectrometer. The lymphatic vessels and nodes at the gastric wall were observed by the naked eyes. Results Black tiny lymphatic vessels and lymph nodes were visualized around the injection areas immediately after the injection. Adriamycin content could be detected 30 min after the injection and lasted for 72 h at high levels with the peak content of ( 84. 6±2. 0) μg per gram tissue at 60 min in the paralymph node of gastroepiploic artery. The adriamycin concentration in the lymph fluid of thoracic duct reached the top level of 162. 5 ng/ml 30 min after the injection, and then decreased slowly. Adriamycin could be still detected in lymph fluid 6 h after injection. No trace of adriamycin was found in the blood at any time points. Conclusion The content of adriamycin can keep high and last long in the drainage of lymph node and lymph fluid in the treatment of intralymphatic chemotherapy using adriamycin-adsorbing nanometric activated carbon.
