Effects of Polymeric Zinc Propylen-Bis-Dithiocarbamate (Propineb) on Nasal Mucosa in Rats International Journal of Morphology
Samanci,Baver; Arslan,Eda; Samanci,Seyla Bolukbasi; Caypinar,Basak; Deveci,Engin; Söker,Sevda; Seker,Ugur.
The objective of this study was to evaluate the histopathologic and immunohistochemical effects of propineb on rat nasal mucosa. Twenty adult Sprague-Dawley rats weighing 180­220 g, were used as experimental animals. The rats were divided into propineb and control groups. The control group 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 that degenerative changes in epithelium were observed in sections of propineb-treated group. There were also leukocyte infiltration and vascular dilatation detected in the connective tissue.We detected CD34-immunoreactive mononuclear...

The Effects of Polymeric Zinc Propylen-Bis-Dithiocarbamate (Propineb) on Tooth Development in Rats International Journal of Morphology
Mahmut,Koparal; Faruk,Er; Engin,Deveci; Dilek,Yavuz.
Dithiocarbamate propinebs are organometal fungicides that are widely used for the control of diseases in plants. In this study, pregnant female rats received 400 ppm propineb concentrations in 5 ml distilled water for 16 days of gestation, and then infant rats were obtained by cesarean section. In the histological analysis on the frontal sections, the use of propineb was found effective on odontoblast cell hyperplasia, cell infiltration in the dental papilla, and degeneration in the mesenchymal cells of the outer enamel. The expression of MMP-2 (Matrix Metalloproteinase-2) and VEGF (Endothelial cell growth factor) in the connective tissue was evaluated by immunohistochemistry. The drinking water given to the mothers in propineb tooth bud, enamel and...

Ultrastructural Effects of the Propineb on Brain of Fetuses During Rat Pregnancy International Journal of Morphology
Ekinci,C; Tahaoglu,A. E; Yavuz,D; Deveci,E; Aktas,A; Yilmaz,T; Yumusak,Ö; Yükselmis,O.
Propineb is a fungicide with a propylene-bis-dithiocarbamate structure. Pregnant Wistar rats were exposed to 400 ppm propineb concentrations in 5 ml distilled water, 5 days per week until the end of pregnancy. The rats were treated with propineb for 16 days and the brains of litter rats were sacrificed at first day of birth after which their brains were collected. Ultrastructural examination of the brains of the fetuses and propineb-treated pregnant females revealed a variety of histopathological effects. We suggest that mitochondrial damage may be an effective factor for neuron necrosis. These results supported the proposal that the exposure to fungicides such as propineb and to other naturally occurring compounds which inhibit mitochondrial function, may...
