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 ...
Histopathological changes in the gill, liver and kidney of pacu (Piaractus mesopotamicus, Holmberg, 1887) exposed to various concentrations of trichlorfon
(Journal of Applied Ichthyology, 2009-02-01) [Artigo]
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 ...

(European Neuropsychopharmacology, 2009-09-01) [Artigo]
Determination of calcium by atomic absorption spectrophotometry applied to the preparation of alginate:chitosan complexes
(Revista de Ciencias Farmaceuticas, 2004-12-01) [Artigo]
Polysaccharicles, as alginate and chitosan, have been used to obtain modified release dosage forms. Alginate, due to its property of building gels during the complex formation with calcium ions, allows the building of ...
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 ...

(Phytochemistry, 2003-06-01) [Artigo]
An iridoid glucoside: randinoside, along with five known iridoids: galioside, deacetylasperulosidic acid methyl ester, scandoside methyl ester, geniposide and gardenoside, were isolated from the stems of Randia spinosa. ...
5-HT2 receptor activation in the midbrain periaqueductal grey (PAG) reduces anxiety-like behaviour in mice
(Behavioural Brain Research, 2008-02-11) [Artigo]
It is widely acknowledged that the indoleamine neurotransmitter serotonin (5-HT) plays a dual role in the regulation of anxiety, a role that in part depends upon neuroanatomical locus of action. Thus, whereas stimulation ...
