Comparison of levels of Zinc,Iron and Cadmium in classic meningioma and glioblastoma multiforme [Klasik meninjiom ve glioblastoma multiforme' de çinko,demir ve kadmiyum seviyelerinin kıyaslanması]

Objectives: the aim of this study was to compare trace elements (zinc (zn),iron (fe) and cadmium (cd)) in tissue samples of classic meningiomas and glioblastoma multiformes. methods: this study was performed in the pathologically diagnosed classic meningioma and glioblastoma multiforme specimens (20 specimens in each group and a total of 40 specimens) obtained from operations. measurements of trace elements were performed with shimadzu aa 680 atomic absorption spectrophotometer and p<0.05 was considered as statistically significant. results: the level of iron in classic meningioma specimens was slightly higher than that in glioblastoma multiforme specimens; however it did not reach statistically significant level (p = 0.17). although the level of cadmium in classic meningioma specimens was slightly higher than that in glioblastoma multiforma specimens; it did not reach statistically significant level (p =0. 35). the level of zinc in classic meningioma specimens were statistically higher than that in glioblastoma multiforme specimens (p = 0.02). conclusion: we consider that our findings might have been valuable data for new researches and can contribute to worthwhile information on pathogenesis of meningioma and glioblastoma multiforma. © 2016,ege university press. all rights reserved.
