Effects of Gestational and Lactational Fenvalerate Exposure on Immune and Reproductive Systems of Male Rats
(Journal of Toxicology and Environmental Health: Part A Current Issues, 2010-01-01) [Artigo]
The aim of this study was to determine the consequent reproductive developmental and immunotoxic effects due to exposure to fenvalerate during pregnancy and lactation in male offspring of maternal-treated rats. Pregnant ...
HPLC determination of flumethrin, deltamethrin, cypermethrin, and cyhalothrin residues in the milk and blood of lactating dairy cows
(Journal of Analytical Toxicology, 1997-09-01) [Artigo]
A procedure to determine residue concentrations of synthetic pyrethroid insecticides (flumethrin, deltamethrin, cypermethrin and cyhalothrin) in the milk and blood of lactating dairy cows was developed. Extraction was ...
Permethrin chronic exposure alters motor coordination in rats: Effect of calcium supplementation and amlodipine
(Environmental Toxicology and Pharmacology, 2014-03-01) [Artigo]
Recently was observed that pyrethroids decrease motor coordination and that calcium channels can be important targets for this effect. To contribute with this observation, this work studied the motor coordination and ...
SPERM QUALITY IN ADULT MALE RATS EXPOSED TO CADMIUM IN UTERO and LACTATION
(Journal of Toxicology and Environmental Health: Part A Current Issues, 2012-01-01) [Artigo]
Recent studies indicate that several anomalies of the male reproductive system may be produced by acute or chronic exposure to chemical substances released into the environment, attributed to increased industrial development. ...
Determination of calcium and magnesium in hydroethanolic extracts of propolis by atomic absorption flame spectrophotometry
(Revista de Ciências Farmacêuticas Básica e Aplicada, 2008-10-28) [Artigo]
Propolis is a natural product collected by honeybees and has a large range of pharmacological activity, including antimicrobial, antitumoral, antioxidant and anti-inflammatory. Its use as a popular medicine is increasing ...
The sympathetic adrenomedullary system, but not the hypothalamic-pituitary-adrenal axis, participates in aorta adaptive response to stress: nitric oxide involvement
(Autonomic Neuroscience-basic & Clinical, 2000-10-02) [Artigo]
Stress induced a decrease in the reactivity of the aorta to noradrenaline (NA), as a consequence of an endothelial nitric oxide (NO) system hyperactivity. The main characteristic of the stress response is activation of the ...
Effect of L-arginine, dimercaptosuccinic acid (DMSA) and the association of L-arginine and DMSA on tissue lead mobilization and blood pressure level in plumbism
(Brazilian Journal of Medical and Biological Research, 2001-10-01) [Artigo]
Lead (Pb)-induced hypertension is characterized by an increase in reactive oxygen species (ROS) and a decrease in nitric oxide (NO). In the present study we evaluated the effect of L-arginine (NO precursor), dimercaptosuccinic ...
Hypnotic, anticonvulsant and muscle relaxant effects of Rubus brasiliensis. Involvement of GABA(A)-system
(Journal of Ethnopharmacology, 2000-06-01) [Artigo]
Rubus brasiliensis hexanic fraction induced anxiolysis in rodents, which was reversed by flumazenil, a specific GABA(A)-benzodiazepine receptor antagonist (Nogueira et al., 1998a,b). Then, we investigated if this hexanic ...
Accumulation of six metals in the mangrove crab Ucides cordatus (Crustacea: Ucididae) and its food source, the red mangrove Rhizophora mangle (Angiosperma: Rhizophoraceae)
(Ecotoxicology and Environmental Safety, 2012-07-01) [Artigo]
The crab Ucides cordatus and the red mangrove Rhizophora mangle are endemic mangrove species and potential bio-accumulators of metals. This study quantified the accumulation of six metals (Cd, Cr, Cu, Hg, Mn and Pb) in ...
Neonatal rat exposure to pyrethroid and organophosphate insecticides: A physiological and biochemical trial of progeny
(Revista de Ciencias Farmaceuticas, 2004-10-14) [Artigo]
A manufactured product (Ectoplus®) composed by a cypermethrin (44.7%) and dichlorvos (4.2%) mixture was administered (10mg/kg/day, orally, by gavage) to pregnant rats, during the periods of gestation+lactation, gestation, ...
