The aim of this study was to evaluate dichlorvos toxicity in terms of nitro-oxidative stress by determining 3-nitrotyrosine (3-NT) levels in the fore, mid, and hindbrain regions in acutely exposed rats. Male SpragueDawley rats were randomly allocated to three groups of eight. Group 1 was administered a single intraperitoneal dichlorvos dose of 1.8 mg kg -1 (0.1xLD 50 ) and group 2 a dose of 9 mg kg -1 (0.5xLD 50 ). The control group received 0.5 mL saline solution via the same route. 3-NT and tyrosine (TYR) levels were measured using high performance liquid chromatography with a photodiode array detector (HPLC-PDA) and expressed as a ratio of 3-NT to TYR. The 3-NT/1000 TYR ratios increased significantly in the fore-, mid-and hindbrains of the exposed groups compared to control (p<0.01). In the forebrain, the increase was also significant between the treated groups. Our study has confirmed that acute exposure to dichlorvos leads to nitro-oxidative stress in the brain and that 3-NT may play a role in the mechanism of dichlorvos neurotoxicity.
As from January 2010 The Israeli Journal of Aquaculture-Bamidgeh (IJA) will be published exclusively as an on-line Open Access (OA) quarterly accessible by all AquacultureHub (http://www.aquaculturehub.org) members and registered individuals and institutions. Please visit our website (http://siamb.org.il) for free registration form, further information and instructions. This transformation from a subscription printed version to an on-line OA journal, aims at supporting the concept that scientific peer-reviewed publications should be made available to all, including those with limited resources. The OA IJA does not enforce author or subscription fees and will endeavor to obtain alternative sources of income to support this policy for as long as possible.
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.
