Efeito da mitomicina C em cultura de estroma de pólipos nasais eosinofílicos: indução de apoptose em eosinófilos

Abstract: A polipose nasossinusal eosinofílica é uma afecção comum a várias doenças, determina acometimento extenso dos seios paranasais e possui grande tendência à recidiva após tratamento. Os eosinófilos exercem papel essencial na patogênese, relacionada a baixo índice de apoptose e a longa permanência destas células ativas nos tecidos. OBJETIVO: Este estudo teve por objetivo avaliar o efeito da mitomicina C na indução de apoptose em eosinófilos presentes no estroma de pólipos nasais eosinofílicos. FORMA DE ESTUDO: Ca… Show more

“…Crossara et al Showed that MMC is efficient in inducing eosinophil apoptosis when these are present in the stroma of eosinophylic nasal polyps. A paired study with nine cultivated samples was carried out and we observed that the MMC treated cultures presented 12-hour apoptosis rate significantly higher in relation to the control group (p<0.001) 15 . MMC proved to have inhibitory action on DNA synthesis, inhibiting the proliferation of many cell lines.…”

“…This cytokine increase is related to the genetic aspect of the NSP eosinophilic cells 5 . Most of the treatment available is based on the use of systemic steroids for a short duration and topical steroid for a longer period, besides surgery 15 . MMC is an antineoplastic agent produced by the Streptomyces caespitosus that has been used as antiproliferative agent in the 0.4mg/ml concentration.…”
