    • The present invention provides methods of treating vascular diseases where nitric oxide insufficiency is a contributing factor by administering a therapeutically effective amount of at least one antioxidant, or a pharmaceutically acceptable salt thereof, and at least one of isosorbide dinitrate and isosorbide mononitrate, and, optionally, at least one nitrosated angiotensin-converting enzyme inhibitor, nitrosated beta-adrenergic blocker, nitrosated calcium channel blocker, nitrosated endothelin antagonist, nitrosated angiotensin II receptor antagonist, nitrosated renin inhibitor, and/or at least one compound used to treat cardiovascular diseases. The antioxidant is preferably a hydralazine compound or a pharmaceutically acceptable salt thereof. The present invention also provides methods of treating vascular diseases where nitric oxide insufficiency is a contributing factor by administering a therapeutically effective amount of at least one nitrosated angiotensin-converting enzyme inhibitor, nitrosated beta-adrenergic blocker, nitrosated calcium channel blocker, nitrosated endothelin antagonist, nitrosated angiotensin II receptor antagonist, nitrosated renin inhibitor, and, optionally, at least one antioxidant and/or at least one compound used to treat cardiovascular diseases. The present invention also provides methods of treating Raynaud's syndrome by administering a therapeutically effective amount of at least one antioxidant and at least one of isosorbide dinitrate and isosorbide mononitrate and/or at least one nitrosated angiotensin-converting enzyme inhibitor, nitrosated calcium channel blocker, nitrosated endothelin antagonist, nitrosated angiotensin II receptor antagonist, nitrosated renin inhibitor. The present invention also provides novel transdermal patches comprising at least one antioxidant and at least one of isosorbide dinitrate and isosorbide mononitrate and/or at least one nitrosated angiotensin-converting enzyme inhibitor, nitrosated beta-adrenergic blocker, nitrosated calcium channel blocker, nitrosated endothelin antagonist, nitrosated angiotensin II receptor antagonist, nitrosated renin inhibitor.

    • Individual thiols present in a biological sample are separated and identified using capillary electrophoresis. S-nitrosated and oxidized derivatives of thiols are also detected using capillary electrophoresis. In addition, capillary electrophoresis may be performed on samples which have been treated with an acid, so as to achieve a pH between 2.0 and 6.8, in order to further enhance detection. Separation and detection of S-nitrosated derivatives of thiols provides a means for monitoring the extent of a disease state associated with abnormal levels of nitric oxide. Such disease states include septic shock, cardiogenic shock, hypovolemic shock, atherosclerosis, hyperhomocysteinemia, venous thrombosis, arterial thrombosis, coronary occlusion, pulmonary embolism, cerebrovascular accidents, vascular fibrosis, ectopia lentis, osteoporosis, mental retardation, skeletal deformities, pulmonary hypertension, malignancy, infections and central nervous system disorders.
    • 使用毛细管电泳分离和鉴定存在于生物样品中的单个硫醇。 也使用毛细管电泳检测硫醇的S-亚硝基化和氧化衍生物。 此外,为了进一步增强检测,可以对已经用酸处理的样品进行毛细管电泳,以达到2.0至6.8之间的pH。 硫醇的S-亚硝基化衍生物的分离和检测提供了监测与一氧化氮异常水平相关的疾病状态的程度的手段。 这种疾病状态包括脓毒性休克,心源性休克,低血容量性休克,动脉粥样硬化,高同型半胱氨酸血症,静脉血栓形成,动脉血栓形成,冠状动脉闭塞,肺栓塞,脑血管意外,血管纤维化,胰岛异位症,骨质疏松症,精神发育迟滞,骨骼畸形,肺动脉高压,恶性肿瘤 ,感染和中枢神经系统疾病。
