    The effect of dexamethasone on gastric mucosal changes following sialoadenectomy in rat
    (Editrice Kurtis S R L, 2005) Elitok, B; Elitok, ÖM; Ketani, MA; Kurt, D; Kanay, Z
    In this study, dexamethasone-induced gastric lesions were studied in rats that had undergone sialoadenectomy. The ultrastructural changes developed during the study were detected by electron microscopically, while blood serum and stomach epidermal growth factor (EGF) concentrations were measured by RIA. The result of the study showed that gastric lesions were correlated with gastric mucus secretion and both serum and mucosa EGF levels. After the administration of dexamethasone, it was found that sialoadenectomy significantly (p < 0.01) raised the incidence of stomach lesions (p < 0.01), and a significant increase in mucus secretion was also found. Additionally, the serum and gastric mucosal EGF levels fell after sialoadenectomy when compared to normal rats. The most important gastric mucosal changes were observed in rats treated with dexamethasone and those both sialoadenectomised and treated with clexamethasone.

    An investigation of the copper (Cu), zinc (Zn) and selenium (Se) levels of blood serum and the Cu and Zn levels of wool of Akkaraman ewes in the Diyarbakir region
    (Scientific Technical Research Council Turkey, 2001) Kurt, D; Denli, O; Kanay, Z; Güzel, C; Ceylan, K
    The aim of this study is to determine the copper, zinc and selenium levels of blood serum and the Cu and Zn levels of wool of healthy Akkaraman ewes grazed in the meadows in the Diyarbakir region. A total of 60 units of blood and wool samples from various villages in different counties of Diyarbakir (Bismil, Cinar, Ergani, Silvan, Kocakoy and some Diyarbakir villages] were studied. The Cu, Zn and Se levels of sera and the Cu and Zn levels of wool were analyzed by flameless atomic absorption spectrophotometer. We found significant differences in Cu and Se levels of sera, in Cu levels of wool (p<0.01) and in Zn levels of wool (p<0.05 ) in ewes from various counties, whereas no significant differences were observed in Zn levels of sera (p>0.05). Although there were considerable differences from county to county, the average values of these counties and herds that indicated the lowest Values in respect to Cu and Zn contents were found to be either similar to or just over the normal values. However, in the case of the selenium content, the average serum Se level of the Akkaraman ewes from various counties of Diyarbakir, except the central county, was found to be remarkably lower than the normal values. In the light of these findings, the rations of animals grazing in meadows are recommended to be reinforced with Se content.
