Other Erratum: Protective Effect of Zinc on Cyclophosphamide-Induced Hematoxicity and Urotoxicity: (biol Trace Elem Res (2008) 126 (186-193) Doi 10.1007/S12011-008-8189-5)(Humana Press, 2009) Ayhancı, Adnan; Uyar, Ruhi; Aral, Erinç; Kabadere, Selda; Appak, SılaThe original version of this article unfortunately contained a mistake. The Materials and Methods section should include last paragraph. Section “Materials and Methods”, inclusion of the last paragraph should read: Only the groups which had CY treatment alone were killed 3 days after the CY injection. For the groups having Cy+ZnCl2 , ZnCl2 administration was started three days earlier than the CY administration and continued till the end of the experiment (6 days). On the fourth day the animals were weighed again, relative doses of CY were estimated and CY+ZnCl2 was administered together. On the seventh day blood samples were collected, bone marrow and the urinary bladders of the animals were resected under anesthesia. Also, the first three affiliations were incorrect. The correct information is given below.Article Citation - WoS: 16Citation - Scopus: 17Protective Effect of Zinc on Cyclophosphamide-Induced Hematoxicity and Urotoxicity(Humana Press, 2008) Ayhancı, Adnan; Uyar, Ruhi; Aral, Erinç; Kabadere, Selda; Appak, SılaCyclophosphamide (CP) is widely used for the treatment of neoplastic diseases; however, its toxicity causes dose-limiting side effects. Zinc (Zn) is an essential trace element and has important biological functions that control many cell processes including DNA synthesis, normal growth, reproduction, fetal development, bone formation, and wound healing. Therefore, the toxicity of CP and the possible protective effect of Zn on blood cells, bone marrow, and bladder of rat were investigated in this study. Intraperitoneal administration of 50, 100, or 150 mg/kg CP for 3 days caused, in a dose-dependent manner, reductions in the number of leukocytes, thrombocytes, and bone marrow nucleated cells and a serious urotoxicity. To explore whether CP-induced damages could be prevented by Zn, other groups of rats were pretreated with 4 or 8 mg/kg ZnCl2 intraperitoneally for 3 days then challenged with respective doses of CP plus ZnCl2 on day 4 for three more days. The results indicated that treatment of rats with Zn could dose-dependently alleviate CP-induced toxicities on blood cells, bone marrow cells, and urinary bladder. We suggest that Zn could be a potentially effective drug in the prevention of CP-related hematoxicity and urotoxicity.Article Citation - WoS: 249Citation - Scopus: 268Silver, Zinc, and Copper Exchange in a Na-Clinoptilolite and Resulting Effect on Antibacterial Activity(Elsevier Ltd., 2004) Top, Ayben; Ülkü, SemraAg+-Na+, Zn2+-Na+, and Cu2+-Na+ equilibria for clinoptilolite-rich mineral from Gördes (Western Anatolia) were investigated at 25 °C and 0.1 N total solution normality. While silver exchange was favorable over the whole concentration range, zinc and copper were partially exchanged and preferred only at low concentrations. The standard free energies of exchanges for Ag+-Na+, Zn2+-Na+, and Cu2+-Na+ pairs were found as -6.0, 2.03, and 3.09 kJ/equiv., respectively. From these values, selectivity sequence was determined as Ag+>Na+ >Zn2+>Cu2+. Antibacterial activities of the exchanged samples were measured as a function of exchange level against Pseudomonas aeruginosa and Escherichia coli. Considering the selectivity sequence of the clinoptilolite and antibacterial activity results, Ag-clinoptilolite seemed to be promising antibacterial material.Article Citation - WoS: 43Citation - Scopus: 47Aas, Xrpd, Sem/Eds, and Ftir Characterization of Zn2+ Retention by Calcite, Calcite–kaolinite, and Calcite–clinoptilolite Minerals(Elsevier Ltd., 2005) Shahwan, Talal; Zünbül, Banu; Tunusoğlu, Özge; Eroğlu, Ahmet EminIn this study, the sorption behavior of Zn2+ on calcite, kaolinite, and clinoptilolite, in addition to mixtures of calcite with kaolinite and clinoptilolite, was investigated at various loadings and mixture compositions using atomic absorption spectroscopy, scanning electron microscopy/energy dispersive X-ray spectroscopy, X-ray powder diffraction, and Fourier transform infrared techniques. According to the obtained results, within the experimental operating conditions, the sorption capacity was enhanced with increasing amount of calcite in both types of mixtures. Under neutral–alkaline pH conditions and high loadings, the order of Zn2+ retention was observed as calcite > clinoptilolite > kaolinite. The experiments on the retention of Zn2+ by pure calcite under conditions of oversaturation showed that the uptake process proceeds via an initial adsorption mechanism (possibly ion-exchange type) followed by a slower mechanism that leads to the overgrowth of the hydrozincite phase, Zn5(OH)6(CO3)2.
