Evaluation of antidiarrhoeal effects of Psidium guajava L. (Myrtaceae) aqueous leaf extract in mice
(Revista de Ciências Farmacêuticas Básica e Aplicada, 2006-12-01) [Artigo]
A crude aqueous extract of the leaves of the guava tree, Psidium guajava L. (Myrtaceae), were studied for antidiarrhoeal effects, to place one of its traditional medical uses. The extract induced a decrease in the propulsive ...
Effect of nωnla, an inhibitor of No-synthase, on the release of tissue-plasminogem activator from rat aorta
(Revista de Ciencias Farmaceuticas, 2003-12-01) [Artigo]
Alterations in the synthesis or enhanced inactivation of nitric oxide (NO) and increase in fibrin deposition in the vascular bed lead to an imbalance that can induced intravascular coagulation. NO is produced through ...
Effect of NωNLA or dexamethasone on vascular hyporeactivity induced by E. coli endotoxin in sham and adrenalectomized rats
(Revista de Ciencias Farmaceuticas, 2000-12-01) [Artigo]
Induction of iNOS by bacterial products is considered to be part of the defense mechanism against infection. However, it has been suggested that the bacterial-induced NO-overproduction may be involved in the vascular ...
Determination of acetonitrile and cyanide in rat blood: Application to an experimental study
(Journal of Analytical Toxicology, 2005-03-01) [Artigo]
Methods were developed for the analysis of acetonitrile and its metabolite cyanide in the blood of rats exposed to acetonitrile. Acetonitrile was analyzed by the headspace technique coupled to gas chromatography with ...
Vascular hyporeactivity to angiotensin II induced by Escherichia coli endotoxin is reversed by Nω-Nitro-L-Arginine, an inhibitor of nitric oxide synthase
(Revista de Ciências Farmacêuticas Básica e Aplicada, 2007-12-01) [Artigo]
Septic shock or sepsis is reported to be one of the major causes of death when followed by systemic infectious trauma in humans and other mammals. Its development leads to a large drop in blood pressure and a reduction in ...
Organophosphate induced delayed neuropathy in genetically dissimilar chickens: Studies with tri-ortho-cresyl phosphate (TOCP) and trichlorfon
(Toxicology Letters, 2002-12-15) [Artigo]
Measurements of plasma cholinesterase (pl.ChE), brain cholinesterase (Br.ChE) and brain Neuropathy Target Esterase (Br.NTE) were made in three different lineages of chickens. All birds received toxicants through gavage in ...
