Abstract:The TXRF technique (total reflection X-ray fluorescence) was employed to analyze the concentration of zinc (Zn) and other metals in the pineal gland of rats submitted to orally administered excess dose of Zn sulfate. The histochemical localization of Zn was also performed. TXRF results showed a 42.9% increase in Zn concentration, and alterations on the homeostasis of other essential elements in rats. It was concluded that TXRF is a suitable technique for measuring, for the first time in this work, the concentr… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
