摘要
目的 :研究汉防己甲素聚乳酸微球的肺靶向性。方法 :分别对小鼠尾静脉注射汉防己甲素聚乳酸微球和汉防己甲素注射剂 ,以反相高效液相色谱法测定并比较小鼠各组织中汉防己甲素的浓度。结果 :汉防己甲素在血浆中检测浓度范围为0 .519～17 000μg/ml(r=0. 9996) ,加样回收率为97 .32 % ,相对标准差平均值为4 .46 % ;应用汉防己甲素聚乳酸微球后汉防己甲素在小鼠各组织中浓度明显高于汉防己甲素注射剂 ;汉防己甲素在小鼠肺中浓度明显高于其它组织。结论 :汉防己甲素聚乳酸微球具有明显的肺靶向性。
OBJECTIVE:To study the lung targeted characteristic of tetrandrine polylactic acid microsphere(TPM).MET_HODS:TPM and tetrandrine injection were injected intravenously into mouse,an RP-HPLC was established to measure the content of TPM in biological samples,and the concentrations of tetrandrine in different tissues of mice were determined and compared.RESULTS:The determinable concentration of tetrandrine in plasma was in the linear range of 0.519～17.000μg/ml(r=0.9 996),the recovery was 97.32%,the mean value of RSD was 4.46%.After the use of TPM,the concentrations of tetrandrine in mouse tissues were significantly higher than tetrandrine injection,and the highest concentration was detected in lungs of mouse.CONCLUSIONS:TPM is distinguishingly lung targeted.
