The aim of this study is to investigate the effect of quercetin on iron induced toxicity on the heart and brain in adult male albino rats. 50 adult male albino rats were equally divided into groups; Group I (negative control), Group II (positive control) received normal saline 0.9%. Group III (Quercetin group) was treated with quercetin (2 g/kg daily) for 8 weeks and Group IV (Iron group) was injected intraperitoneal daily with iron dextran (300 mg/kg) for 4 weeks. Group V (Iron and quercetin group) was injected intraperitoneal daily with iron dextran (300 mg/kg) for 4 weeks, and then gavaged orally with quercetin (2 g/kg once a day) for another 4 weeks. At the end of the study, blood samples were taken to estimate the serum levels of iron, malondialdehyde (MDA), and total antioxidant capacity (TAC). Heart and brain specimens were dissected from scarified rats to estimate tissue level of iron, histopathological examination, immunohistochemical staining for tumor necrosis factor (TNFα) and comet assay. Iron overload caused increases in serum, heart and brain iron levels; increase in serum MDA and decrease in serum TAC with degenerative changes in the examined tissues and increasing expression of TNFα and DNA degradation. After administration of quercetin, a significant improvement in all these parameters was observed. Quercetin acts as iron chelator decreasing serum and tissue iron levels, ameliorating oxidative stress, inflammatory effects and DNA damage induced by iron overload. More studies are recommended to evaluate the beneficial effects of quercetin with iron excess. \u0000 \u0000 Key words: Iron, quercetin, heart toxicity, brain toxicity.","PeriodicalId":17507,"journal":{"name":"Journal of Toxicology and Environmental Health Sciences","volume":"15 1","pages":"16-26"},"PeriodicalIF":0.0,"publicationDate":"2019-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82467220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experimental fish were exposed to piscicide plant extract of 0.0 (control), 15.0, 17.5, 20.0, 22.5, and 25.0 mgL-1. Fish exposed to these extracts except the control showed symptoms of toxicity including darting, agitated swimming, air gulping, loss of sensitivity and knockdown before death. These responses were much frequent and faster in L. bynni and L. intermedius. The 96 h LC50 values for the different test fishes were 18.99, 20.72 and 20.72 mg L-1 for L. bynni, L. intermedius and B. nurse, respectively. Based on the present investigation, we can conclude that the application of B. aegyptiaca extract causes lethal toxic effects on different fishes even at low concentrations and hence, indiscriminate use of the plant for fishing should be discouraged and regulated in order to protect fish biodiversity lose in the Alitash National Park area. \u0000 \u0000 Key words: Alitash National Park (ALNP), Balanites aegyptiaca, floodplain rivers, piscicide, toxicity, LC50.","PeriodicalId":17507,"journal":{"name":"Journal of Toxicology and Environmental Health Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90697340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fourteen PAHs were detected in the samples. The results showed that flourene and phenanthrene were common to all the patients in the range (1.37 to 8.08 and 1.66 to 8.34 ng/mL respectively), but were not detected in the control samples.

These were not found in the control samples. The body burden of these congeners was much higher in neurology patients than controls and literature values of similar study.
