1. Treatment with some anti-inflammatory drugs reduces germ tube formation in Candida albicans strains
Candida albicans is an opportunistic dimorphic fungus that inhabits various host mucosal sites. It can cause both superficial and serious systemic disease. Conversion from the yeast to the hyphal form has been associated with increased virulence and mucosal invasiveness. The aim of this study was to investigate the effect of sodium diclofenac and aspirin on

2. ESTUDO DOS EFEITOSDA BRADICININA SOBRE A FUNÇÃO RENAL DE RATOS / STUDY OF EFEITOSDA bradykinin ON RENAL FUNCTION IN RATS
O sistema calicreína-cinina corresponde a uma cascata metabólica endógena, que resulta na liberação de cininas vasoativas, das quais a mais conhecida é a bradicinina (BK). Esta cinina está envolvida tanto na regulação da função renal, como também da pressão arterial, estimulando efeito hipotensor, natriurético e elucidados. O presente trabalho

3. Temporal evaluation of c-fos expression in amygdaloid and hypothalamic areas following experimental tooth movement in rats / Avaliação temporal da expressão da proteína FOS em áreas amigdalóides e hipotalâmicas após movimentação dentária experimental em ratos
In the accomplishment of the orthodontic treatment, it is described that the pain happens immediately after the application of orthodontic forces and disappears after few days. Regarding the neural pathways involved in the sensorial mediation of the orthodontic movement (OM) few are the studies that approach this theme, and in the last decades solid founds d

4. Renal effects promoted by myotoxins and lectins isolated from the snake venoms of Bothrops jararacusu and Bothrops moojeni. The role of cyclooxigenase and endothelin / Efeitos renais de miotoxinas e lectinas purificadas dos venenos das serpentes Bothrops jararacussu e Bothrops moojeni. Papel da ciclooxigenase e endotelina
Acute renal failure is one of the most common systemic complications after snakebite. However, its pathogenesis remains obscure. In this study, we evaluated the renal effects of Bothrops jararacussu myotoxins I and II (Bthtx-I Lys 49 and BthtxII, Asp 49), Bothrops moojeni myotoxin I and the lectins from Bothrops moojeni and Bothrops jararacussu. Attempting t

5. Vascular reactivity of isolated aorta of late pregnant rats: role of nitric oxide and prostaglandins. / "Reatividade vascular de aortas isoladas de ratas ao término da gestação: participação de óxido nítrico e prostanóides"
Late pregnancy is associated with diminished reactivity to vasoconstrictor agents that may be mediated by altered production/release of nitric oxide (NO) and prostaglandins. In the present study the role of NO synthase (NOS) and cyclooxygenase (COX) derived products in the altered vascular reactivity to phenylephrine (PE) was investigated in the isolated aor

6. The Effect of Chronic Sodium Loading and Sodium Restriction on Plasma Prostaglandin A, E and F Concentrations in Normal Humans
It has been suggested that prostaglandins may be involved in the control of sodium homeostasis. Prostaglandin A and prostaglandin E have been shown to increase renal blood flow and urinary sodium excretion and prostaglandin A has been shown to stimulate aldosterone release. The purpose of this study was to determine the effect of chronic sodium loading and s

7. Modes of action of aspirin-like drugs.
Current dogma holds that nonsteroidal anti-inflammatory drugs (NSAIDs) act by inhibition of the synthesis and release of prostaglandins. However, NSAIDs also inhibit the activation of neutrophils, which provoke inflammation by releasing products other than prostaglandins. We now report that NSAIDs (e.g., indomethacin, piroxicam) inhibit activation of neutrop

8. Multiple control of fever production in the central nervous system of rabbits.
1. The effects of microinjection of prostaglandin D2, E2 and F2 alpha and of endogenous pyrogen on the rectal temperature of rabbits were extensively examined in sixty-eight brain regions and in the third cerebral ventricle. 2. Intracerebroventricular injection of both prostaglandins E2 and F2 alpha produced dose-dependent fever over a range of 100-1000 ng.

9. Inhibition of sodium metabisulphite induced bronchoconstriction by frusemide in asthma: role of cyclooxygenase products.
BACKGROUND--Inhaled frusemide inhibits airway responses to sodium metabisulphite and other indirect bronchial challenges in asthma by undetermined mechanisms which may relate to its ability to stimulate prostaglandin release. Inhalation of sodium metabisulphite provokes indirect bronchoconstriction, possibly by activating sensory nerves. To investigate the r

10. Prostaglandin synthesis in isolated rat kidney glomeruli.
Isolated rat kidney glomeruli converted octatritiated arachidonic acid to several prostaglandins whose production was inhibited by meclofenamate. These were, in order of decreasing abundance, prostaglandin F2 alpha, prostaglandin E2, 6-oxo-prostaglandin F1 alpha, thromboxane B2, and prostaglandin D2. These products were identified by thin-layer chromatograph

11. Stereospecific Binding of the Potent Narcotic Analgesic [3H]Etorphine to Rat-Brain Homogenate
Etorphine, the most potent narcotic analgesic known, was labeled with tritium by catalytic exchange. This drug exhibits stereospecific, saturable binding to rat-brain homogenate. At saturation, the stereospecific binding is 0.1-0.15 pmol/mg of protein. Specific binding is inhibited high salt concentrations, sulfhydryl reagents, and proteolytic enzymes, but i

12. Prostanoids and blood pressure: which way is up?
Members of the family of prostanoids, made up of prostaglandins and thromboxanes, are generated via COX-mediated metabolism of arachidonic acid. These lipid mediators exhibit wide-ranging biological actions that include regulating both vasomotor tone and renal sodium excretion. As COX inhibition is often associated with sodium retention leading to edema and
