The neuroprotective role of nimodipine was tested in kainic acid (50 and 100 microM) induced neurotoxicity in cerebellar granular cell cultures of 4 to 7 day-old rat pups. Nimodipine was applied in 50, 100 and 200 microM concentrations. Kainate, in either dose, induced cerebellar granular cell death in respect to controls and the results were statistically(More)
To determine the genotoxic risk associated with diagnostic exposure to low doses of iodine 131 (131I), sister chromatid exchange (SCE) analysis was performed in lymphocytes of 18 non-smoking women who received 370 kBq (10 microCi) intravenous 131I sodium iodide as an adjuvant for scintigraphy for diagnosing thyroid nodularity. SCE frequencies were measured(More)
Breast tuberculosis is an uncommon illness. It is predominant in young women. To our knowledge, only 7 cases of tuberculous mastitis in men have been reported in the English literature since 1945. Furthermore, there are no male patients who have breast and osteoarticular tuberculosis in the literature. We presented a 41-year-old man who was admitted with a(More)
Behçet's disease (BD) (OMIM 109650) is an immunogenetically based multisystem disease, characterized by iridocyclitis, arthritis, orogenital ulcerations and pustular skin lesions. Viral and autoimmune etiologies have been suggested and HLA-B5 has been found to predominate in BD. The disease is most seen in Turkey and Japan. Although familial cases have been(More)
OBJECTIVE This study investigated whether any genomic change occurs in DNA level in ankylosing spondylitis (AS) by measuring sister chromatid exchange (SCE) frequency. METHODS SCE frequency was detected on metaphase chromosomes obtained from peripheral blood lymphocyte cultures in 15 patients diagnosed as having AS. SCE values were also obtained from 15(More)
In this study, norepinephrine was tested in 0.1, 1, 10, 25 and 50 microM doses in 100 microM NMDA toxicity on cerebellar granular cell culture of rats. NMDA in 100 microM concentration induced cell death significantly with respect to controls. Death cell population was 1.08 +/- 0.44% in control and 22.15 +/- 2.46% in 100 microM NMDA (P < 0.0001). None of(More)
Methylxanthines (theophylline, theobromine and caffeine) are widely used as central nervous system stimulants and caffeine is used in the treatment of apnea in newborns. Plasma therapeutic concentration of caffeine is around 110 microM. Caffeine diffuses the blood brain barrier easily, increasing oxygen consumption in neurones and leading to cell death. In(More)
