An in vivo method is described showing how selective killing of macrophages in the peritoneal cavity by carrageenan affects Eimeria tenella infection in chickens. Killing of macrophages was demonstrated by the increasing loss of cytoplasmic contents under light microscopy, by the disappearance of
Cells were harvested from rat pleural cavity before and during the inflammatory response stimulated by carrageenan injection. The conversion of [14C]arachidonate by intact cells into products of the cyclooxygenase and 5-lipoxygenase pathways was studied in the absence and presence of ionophore.
The mechanism of iota-carrageenan (i-CAR)-induced protection against murine cytomegalovirus (MCMV) infection of mice was analysed. The virus titres in the target organs on the fourth day correlated with that in the plasma at 1 h after intraperitoneal inoculation of MCMV, irrespective of i-CAR
Polymorphonuclear leucocyte (PMNL) migration and oedema induced by carrageenan in the pleural cavity and paw, respectively, of rats made hyper- or hypothermic by physical and chemical means have been investigated. In rats placed in a warm environment to produce a rise in body temperature,
BACKGROUND
Senecio brasiliensis (Spreng) Less (S. brasiliensis), known as "Flor-das-almas", "Margaridinha" or "Maria mole", is used in folk medicine as an anti-inflammatory and to treat gastric ulcers and stomach pain. While the Senecio genus has been widely studied for its pharmacological
BACKGROUND
Ageratum conyzoides Linn (Asteraceae), a tropical plant that is very common in West Africa and some parts of Asia and South America, has been used to treat inflammatory disorders. In Brazil, teas made from A. conyzoides L. are used as anti-inflammatory, analgesic and anti-diarrheic
Temporomandibular disorders represent one of the major challenges in dentistry therapeutics. This study was undertaken to evaluate the time course of carrageenan-induced inflammation in the rat temporomandibular joint (TMJ) and to investigate the role of tachykinin NK(1) receptors. Inflammation was
The intrapleural injection of carrageenan in the rat induces exudate formation, cellular influx and leukotriene generation in the pleural cavity. We have demonstrated that the inflammatory response (exudate volume, and LTB4 levels) is increased in situ by the intrapleural administration of calcium
We report the effect of gold nanoparticles (AuNP) in an acute inflammation model induced by carrageenan (CG) and compared this effect with those induced by the antioxidant N-acetylcysteine (NAC) alone and by the synergistic effect of NAC and AuNP together. Male Wistar rats received saline or saline
Several emerging lines of evidence support an anti-inflammatory role for nicotinic acid (niacin); however, its role in the regulation of leukocyte migration in response to inflammatory stimuli has not been elucidated until now. Herein, we have examined the effect of nicotinic acid on neutrophil
The injection of carrageenan into the rat pleural cavity provoked an intense inflammatory reaction with the formation of an exudate which contained mainly neutrophils but which was also rich in mast cells and histamine. There was, however, no evidence that histamine participated in the reaction. The
The cellular origin and kinetics of TXB2 and 6-keto PGF1 alpha in carrageenan-induced pleurisy has been studied. Maximum levels of these prostanoids occurred 1 hour after induction of pleurisy. Mononuclear cells initially present in the pleural cavity synthesized TXB2 and 6-keto PGF1 alpha from
OBJECTIVE
Antithrombin is known as the most important natural coagulation inhibitor and has been shown to have anti-inflammatory properties. The present study aimed to investigate the effects of Bothrops jararaca antithrombin on acute inflammation induced by carrageenan in mice.
METHODS
We evaluated
BACKGROUND
Polygala sabulosa, popularly known as "timutu-pinheirinho," has been used in Brazilian folk medicine for the treatment of bowel and kidney disorders and as an expectorant.
OBJECTIVE
Evaluate the anti-inflammatory effects of the crude extract (CE), acetonic fraction (Ac), and the main
OBJECTIVE
The aim of this study was to investigate the anti-inflammatory effects of the crude hydroalcoholic extract (CHE) isolated from Esenbeckia leiocarpa Engl., and fractions and subfractions derived from it.
METHODS
Dried E. leiocarpa Engl. bark was macerated and extracted with ethanol to
