BACKGROUND Uterine leiomyomas (fibroids) are the most common gynaecological benign tumors in premenopausal women. Evidences support the role of oxidative stress in the development of uterine leiomyoma. We have analysed oxidative stress markers (thiols, advanced oxidized protein products (AOPP), protein carbonyls and nitrates/nitrites) in preoperative sera from women with histologically proven u...

As reported in our previous studies, dithiaden (an antagonist of histamine H(1)-receptor, used clinically as an anti-allergic or anti-emetic drug) in a concentration range of 5×10(-5)-10(-4) M decreased the production of reactive oxygen species by phagocytes. In this study we investigated the influence of dithiaden on nitric oxide (NO) production by LPS-stimulated macrophages.The cell viability...
