Öğe The effect of propolisis and mesalazine on bacterial translocation in an experimental colitis model(Saudi Med J, 2007) Aslan, Ahmet; Cetin, Meryem; Temiz, Muhyittin; Sahinler, Nuray; Besirov, Elmir; Aban, Nedim[Abstract Not Available]Öğe Effectiveness of mesalamine and propolis in experimental colitis(Springer, 2007) Aslan, Ahmet; Temiz, Muhyittin; Atik, Esin; Polat, Gurbuz; Sahinler, Nuray; Besirov, Eimir; Aban, NedimThis study was conducted to investigate the effects of propolis and mesalamine on experimental colitis in rats. Distal colitis was induced in rats by intracolonic instillation of 2 mL of 4% acetic acid. The animals were randomly assigned to 5 groups: group 1, control, (n=8); group 2, colitis, received no treatment (n=8); group 3, colitis+mesalamine, 2 mL once a day via an enema (n=8); group 4, colitis+propolis, 600 mg/kg once a day via intragastric lavage (n=8); and group 5, colitis+ mesalamine+propolis for 1 wk (n=8). Levels of nitric oxide were statistically significantly different in comparisons between groups 1 and 2, groups 2 and 3, and groups 4 and 5. Malondialdehyde levels were significantly different when group 2 was compared with groups 3, 4, and 5. A significant difference was observed when group 3 was compared with group 4 for myeloperoxidase. Most propolis-treated rats had normal histology; mesalamine-treated and propolis+mesalamine-treated rats had inflammatory cell infiltration at rates of 50% and 33%, respectively. The investigators concluded that propolis and mesalamine are efficient independently and in combination, but that their combined effect was not observed to be additive in experimental colitis.Öğe Expression of cyclooxygenase-2 and its relation to histological grade, inducible nitric oxide synthase, matrix metalloproteinase-2, CD-34, Caspase-3, and CD8 in invasive ductal carcinoma of the breast(Saudi Med J, 2010) Atik, Esin; Akansu, Bulent; Bakaris, Sevgi; Aban, NedimObjectives: To assess by immunohistochemistry the cyclooxygenase-2 (COX-2) expression in invasive ductal carcinoma and its possible correlation with the histological grade, inducible nitric oxide synthase (iNOS), matrix metalloproteinase-2 (MMP2), and other common immunohistochemical parameters (CD-34, Caspase-3, and CD8). Methods: This was a retrospective pathology archive study including 50 female patients and was performed in Mustafa Kemal University, Hatay, and Sutcu Imam University, Kahraman Maras, Turkey. The routine hematoxylin-eosin staining and COX-2, iNOS, MMP-2, CD-34, CASP-3, and CD8 immunoperoxidase techniques were performed on paraffin-embedded tissues. Results: The mean value of COX-2 was 274.02 +/- 54.49 and MMP-2 was 263.42 +/- 54.30, whereas the mean iNOS values were 258.10 +/- 56.05. CD-34 staining also yielded positive results as 26.18 +/- 8.00. The mean value of CASP-3 was 284.06 +/- 41.2 and CD8 was 164.17 +/- 69.5. This reveals an inverse correlation between CASP-3 reactivity and CD8 (Spearman correlation [r]= -0.33, p=0.01). There was also an inverse correlation between iNOS reactivity and patients age (r = -0.29, p=0.03). There was a positive correlation with COX-2 and MMP-2 (p=0.00), but there was no relation with COX-2 and other parameters. Conclusion: COX-2 expression is an important parameter for invasive ductal carcinoma of the breast. We found a positive correlation between COX-2 and MMP-2, whereas, we could not show direct correlation between COX-2 and iNOS, CD-34, CASP-3, and CD8.Öğe Expression of cyclooxygenase-2 and its relation to histological grade, iNOS, MMP-2, CD-34, CASP-3 and CD8 in invasive ductal carcinoma of breast(Springer, 2007) Atik, Esin; Akanasu, Bulent; Bakaris, Sevgi; Aban, Nedim[Abstract Not Available]
