长期使用硝酸甘油而形成的耐药性可能是由于巯基团的耗尽。本研究探讨在硝酸甘油耐药性形成后使用蛋氨酸能否恢复硝酸甘油的静脉扩张作用,而这种氨基酸能够增加巯基的利用度。作者用前臂体积描记平衡法 Long-term use of nitroglycerin and the formation of resistance may be due to the depletion of thiol groups. This study explored whether the use of methionine after nitroglycerin resistance could restore venous dilatation of nitroglycerin, and this amino acid increased the availability of sulfhydryl groups.
