摘要

我们在同一物种(兔)的不同离体导电动脉和静脉血管上测试了经典使用的有机硝基血管扩张剂,如s-亚硝基-乙酰基-d、l-青霉胺、3-morpholino- sydnon亚胺、季戊四硝基-四硝酸酯、异山梨酯-硝酸酯、异山梨酯-单硝酸酯、甘油-三硝酸酯。我们发现,与肺循环相比,体循环的静脉选择性要明显高出两个数量级。ISMN和PETN是最具静脉选择性的硝基血管扩张剂,PETN是所有研究血管中最有效的药物。

Comparison of the vasorelaxing effect of different nitrovasodilators in conductive arterial and venous blood vessels.

We tested classically used organic nitrovasodilators such as s-nitroso-n-acetyl-D,L-penicillamine, 3-morpholino-sydnonimine, pentaerythrityl-tetranitrate, isosorbide-dinitrate, isosorbide-mononitrate, glyceryl-trinitrate on different isolated conductive arterial and venous blood vessels of the same species (rabbit). We found an up to two orders of magnitude more pronounced venoselectivety in the systemic-circulation as compared to the lung-circulation. ISMN and PETN were most venoselective nitrovasodilators, with PETN being the most potent drug in all vessels studied.
