cholesteatoma/glutathione

Context • Oxidative stress and tissue-damaging, oxygen (O2)-related, free-radical formation is inherent in human metabolism, and the tissues of the ear, nose, and throat (ENT) have an increased exposure to injury from those substances. Because glutathione (GSH) is a major component in an antioxidant

Technetium-d, HMPAO SPECT was performed in 70 patients suffering from intracerebral tumors of various histologic types (glioma n = 30, meningioma n = 19, metastases n = 10, angioma n = 3, neuroma n = 2, lymphoma n = 2, neurocytoma n = 1, epidermoid n = 1, gliosis n = 1, cholesteatoma n = 1). Tumor

CONCLUSIONS Depletion of enzymatic antioxidants was observed in cholesteatoma. However, a relationship between activity of enzymatic antioxidants and the extent of bone erosion was not found. OBJECTIVE To measure the level of major enzymatic antioxidants in cholesteatoma, and to investigate the

OBJECTIVE To underline the effect of oxidative stress in chronic otitis media with and without cholesteatoma and to compare the oxidative stress values in the serum and tissue specimens in these two forms. METHODS The study included a total of 75 individuals, 35 cases with chronic otitis media (COM;
