The present invention describes rapid noninvasive methods for measuring vasodilation or changes in blood flow in a patient following administration of at least one compound that donates, transfers or releases nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor, stimulates endogenous synthesis of nitric oxide or is a substrate for nitric oxide synthase and/or at least one vasoactive agent. The method comprises the administration of at least one compound that donates, transfers or releases nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor, stimulates endogenous synthesis of nitric oxide or is a substrate for nitric oxide synthase and/or at least one vasoactive agent to the patient followed by monitoring the temperature change of an area of interest using infrared thermography. The present invention provides methods for diagnosing diseases or disorders related to vasodilation and changes in blood flow, such as, sexual dysfunction, Raynaud's syndrome, inflammation, hypertension, gastrointestinal disorders and central nervous system disorders. The sexual dysfunction is preferably female sexual dysfunction and female sexual arousal. The vasoactive agents include potassium channel activators, calcium channel blockers, &agr;-adrenergic receptor antagonists, &bgr;-blockers, phosphodiesterase inhibitors, adenosine, ergot alkaloids, vasoactive intestinal peptides, prostaglandins, dopamine agonists, opioid antagonists, endothelin antagonists and thromboxane inhibitors. The present invention can also be used to screen and identify drug candidates for treating diseases, disorders and conditions resulting from vasodilation or changes in blood flow. The present invention also describes compositions comprising at least one S-nitrosothiol compound for diagnosing, monitoring and/or treating female sexual dysfunctions.

钙通道阻滞剂、α-
肾上腺素能受体拮抗剂、β-受体阻滞剂、
磷酸二酯酶抑制剂、
腺苷、麦角
生物碱、血管活性肠肽、
前列腺素、
多巴胺激动剂、阿片受体拮抗剂、内皮素拮抗剂和血栓素
抑制剂。本发明还可以用于筛选和鉴定治疗由血管扩张或血流变化引起的疾病、障碍和病症的药物候选物。本发明还描述了包含至少一种S-亚硝基
硫醇化合物的组合物,用于诊断、监测和/或治疗女性性功能障碍。
