Antioxidant defense in rat brain regions after developmental lead exposure
(Toxicology, 2001-12-14) [Artigo]
Oxidative stress is considered a possible molecular mechanism involved in Pb neurotoxicity. Considering the vulnerability of the developing brain to Pb neurotoxicity, this study was carried out to investigate the effects ...
Behavioral effects of acute exposure to the insecticide fipronil
(Pesticide Biochemistry and Physiology, 2011-03-01) [Artigo]
The effects of fipronil (Frontline (R) Top Spot) were investigated in 40 days old rats utilizing open field (OF), hole-board (HB) and elevated plus-maze (EPM) apparatus. Rats (N=15) received topical application of fipronil ...
Anxiety and dopaminergic alterations in adult rats induced by low-level lead exposure during pregnancy and lactation
(Toxicology, 2001-07-08) [Resumo]
Developmental lead exposure in rats: is a behavioral sequel extended at F2 generation?
(Pharmacology Biochemistry and Behavior, 2001-04-01) [Artigo]
Lead toxicity was studied in rats exposed from conception until weaning and assessed by monitoring offspring behavior in both the open field and elevated plus maze and by determining tissue lead in an assessment schedule ...
Interaction between humic substances and metallic ions: A selectivity study of humic substances and their possible therapeutic application
(Journal of the Brazilian Chemical Society, 2007-09-06) [Artigo]
The complexation capacity of humic substances extracted from peat samples taken from the Mogi River in Ribeirao Preto, SP, Brazil, was determined using metal ions (Al(III), Pb(II), Cr(VI) and Cd(II)), yielding the following ...
Behavioural alterations provoked by prolonged calcitonin administration in rats
(Revista Brasileira de Toxicologia, 2003-07-01) [Artigo]
Present work investigated the effect of prolonged administration of salmon calcitonin, a hormone secreted by parafollicular cells from thyroid, on behavioural parameters of rats. Animals received calcitonin sc, 100 mUI/100 ...
