Özet
Maneb (Mn-ethylene(bis)dithiocarbamate is a dithiocarbamate pesticides. It is a fungicide pesticide used in the control of mildew disease on certain crops. In general, dithiocarbamates are considered chemicals of low toxicity for humans. However, the effects of maneb in humans are diverse. It has some effects to humans via absorption through skin and respiratory system. The nasal mucosa is the first part of the airways in contact with the environment and toxic agents. The aim of this study was todetermine the histopathological effects of numb on nasal mucosa. In experimental group, the maneb was administered with inhalation to 10 male Wistar-Albino rats for five days a week. The control group (n=10) received distilled water with spray at the same time period. The experiment was terminated after three weeks. In each case, sections of the nosewere taken. In experimental group,microscopic examination of nasal respiratory mucosa revealed; Hypertrophy of epithelial cells and goblet cells, increasing of mucus secretion, decreasing in sizes of cilia and flattening of the cells near the basement membrane and apoptotic cells in the degenerated respiratory epithelial cells, detected a mild inflammatory reaction and a vascular dilatation in the connective tissue. All changes were statistically significant. In control group of 10 rats no significant histopathologic lesions were found. As a result, our study, maneb is potentially toxic agent to respiratory mucosa.
