  • Malignant fibrous histiocytoma (MFH), a type of sarcoma, is a malignant neoplasm with uncertain origins that arise from both the soft tissues and the bone. The occurrence of MFH on the chest wall is extremely rare. We hereby report a case of a 72-year-old woman who was incidentally detected with MFH after a traffic accident.

  • Malignant melanoma occurs most frequently on the skin. However, it can also arise in other organs and tissues of the body. Primary pulmonary malignant melanoma is a very rare non-epithelial neoplasm accounting for 0.01% of all primary pulmonary tumors. The treatment of choice is surgical resection of the tumor with an oncologically adequate margin as in lobectomy or pneumonectomy. The prognosis of this condition is rather poor. Based on previous data, its 5-year survival is at least 10%. Here, we report a case of an 82-year-old woman whose primary pulmonary melanoma was detected incidentally.

  • The rapid and spontaneous interaction between superoxide anion radical and nitric oxide to yield the potent oxidants. peroxynitrite artion and peroxynitrous acid, was investigated in phorbol myristate acetate(PMA)-stimulated RAW264.7 macrophases by means of lucigenin- or luminol-enhanced chemiluminescence method. When RAW264.7 macrophages were stimulated by PMA. peroxynitrite-induced chemiluminescence was clearly observed. To prove observed chemiluminescencc due to the reaction between superoxide anion radical and nitric oxide produced by RAW264.7 macrophases, N-nitrosoglutathione (GSNO), a nitric oxide-releasing compound. superoxide dismutase(SOD), an enzyme removing superoxide anion radical by dismutating superoxide artion radical to hydrogen peroxide, and N-acethyl cysteine(NAC), a scarvenging reagent both superoxide artion radical and nitric oxide, were added in the cell system. Peroxynitrite- induced chemilumincscence was increased by exogenous addition of GSNO. whereas observed chemiluminescence was decreased by SOD and NAC. These results suggest that PMA-stimulated RAW264.7 macrophages produce both superoxide anion radical and nitric oxide to form peroxynitrite.
