Provedor de dados: 77
Autores: 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...

Autores: Deveci,E; Deveci,S.
Cadmium Chloride (CdC1) is a teratogen which is commonly used in industry. Although it is well known to cause toxicity in testes, kidney, heart and liver, few studies have been carried out in the digestive system. In the present study the effects of CdC1 on the esophagus of rats were investigated Wistar albino rats weighing 180 ­ 200 g were used. The animals were divided into two groups; one group was administered 2 mg/kg/day CdC1 intraperitoneally for one week. Esophagus was removed and placed in 10% formaline. Sections were stained with Hematoxylene-Eosine and observed under light microscopy. Hyperplasia in the epithelium, an increase in fibrotic cells under epithelium, hemorrhage in vessels, free floating erythrocytes were all observed following fetal...

Eight rats were in control group and 8 rats were in the experimental group. The experimental group was exposed to 300 ppm formaldehyde 3­5 min/day, 5 days/week for 8 weeks. The lining epithelium of respiratory mucosa showed a loss of ciliated cells with metaplasia of goblet cells, hyperplasia of squamous cells and edema, inflamation in sub epithelial area). In the group treated xylene. Disruption of cell-cell contact was observed. Weak expression of E-cadherin was observed between cells. The vascular endothelium of capillaries and venoles showed intense immunostaining for VEGF.

A total of 32 Wistar rats were divided into four equal groups: (I) sham, (II) ischemia, (III) reperfusion and (IV) Potentilla fulgens. In groups I and II, ovary torsion was not performed and no drug was administered. In group III, 1 h of ischemia and 2 h of reperfusion were performed and no drug was given. Group IV received 400 mg/kg/day Potentilla fulgens intraperitoneally 5 days before Ischemia-reperfusion. All the parameters were observed to be significantly decreased (P&lt;0.05) in all the experimental groups compared to the control group. In the sections of the ischemia-reperfusion group, degeneration of epithelium, dilation of blood vessels were observed. Potentilla fulgens administration reduced the morphological changes by induced I/R; in...

This study aimed to assess association between preeclampsia with trophoblast cells and serum level of b-human chorionic gonadotropin (ß-hCG). Were compared 20 patients with preeclampsia and 20 control patients with respect to demographics, hematological parameters and the presence of trophopblast in placental samples. Patchy necrosis with loss of microvilli and gross thinning of the syncytium with distorted microvilli were seen in terminal villi of placentae of women with pre-eclampsia Syncytial cells at the molecular level crossings, especially at the level of ßhCG in conjunction with the changes in the preeclampsia was made on the histopathological changes to clarify the villi.

Nicotine is an alkaloid toxic effects of oral cavity. In this study,14 adult Sprague-Dawley rats weighing 230-260 mg (±10 mg) were used as experimental animal. The rats of experimental group (n=6) were nicotinized systemically with nicotine sulphate, 2mg/kg subcutaneously, daily in period of 28 days. Pulp, alveolar bone tissue, periodontal membrane and gingival epithelial junction were investigated in these regions in incisive teeth longitudinal cross-section. Thinning of the collagen fibers in the pulp tissue, vascular congestion, and inflammatory cell infiltration were observed. Mesenchymal tissues that is stained positive for vimentin lay underneath the epithelium. A strong expression of vimentin can be observed in formed periodontal ligament.

Autores: Deveci,E; Söker,S; Baran,Ö; Tunik,S; Ayaz,E; Deveci,S.
The purpose of this study was to investigate the ultrastructural effects of lead on the kidney cortex of rats. Wistar Albino rats (180-200g body weight) were divided into a controlled and lead acetate-exposed group. Rats received lead acetate at 500 ppm in their drinking water for 60 days. Both groups were fed with the same standard food, but lead acetate was added to the drinking water. During the experimental period, blood samples were taken from the abdominal aorta of the anesthetised animals. At the end of exposure, body weight and blood lead levels were measured. The kidney tissue samples were prepared and analyzed by light and transmission electron microscopy. Cortical renal tubules show various degenerative changes with focal tubular necrosis...

Provedor de dados: 77
Autores: Kavak,V; Balsak,D; Togrul,C; Deveci,E; Ekinci,A; Ekinci,C; Babacan,F.
In recent years, disorders related to the development and function of the male reproductive tract has increased, thus generating a surprising decrease in semen volume and sperm count. We examined the effects of low protein and estrogen on sexual behavior and testicular maturation in male rats. We also examined FSH, LH and testosterone levels and histological damage of testis tissue. The male rats were subjected to standard long-term treatment with estradiol by oral and paranteral delivery. The number of mounts, copulatory efficiency and ejaculation latencies for the paranteral protein diet (PPD) group was significantly lower than those in a group nourished with a low protein diet (LPD) and oral protein diet (OPD) groups (P&lt;0.05). Testes and epididymis...

Down syndrome is primarily caused by trisomy of chromosome 21. We reviewed cytogenetic studies performed on 1048 patients who were referred to the Cytogenetics Unit at Dicle University Hospital, Diyarbakir, Southeast Turkey, between 2000 and 2009. The cases were grouped according to the reason of referral for cytogenetic analysis. The highest frequencies of abnormal karyotypes were found among cases that were referred due to suspicion of Down syndrome (84.8%). For histologic examination to persons with Down syndrome and normal, buccal mucosa smear was prepared by rubbing. Down syndrome are disabled and control groups were compared statistically buccal epithelial cells and nuclei (p&lt;0.05). Periphery of the nucleus in some patients with Down's syndrome,...
