Phenolic enriched extract of Baccharis trimera presents anti-inflammatory and antioxidant activities.

Baccharis trimera is a plant popularly used as a tea and to treat gastrointestinal diseases and inflammatory processes as well. The total phenolic content was determined and the antioxidant and anti-inflammatory activities of six extracts (dichloromethane, ethyl acetate, butanol, aqueous, saponin and phenolic) from B. trimera were evaluated.

Treatment with N-methyl-D-aspartate receptor antagonist (MK-801) protects against oxidative stress in lipopolysaccharide-induced acute lung injury in the rat.

Acute lung injury (ALI) and the acute respiratory distress syndrome (ARDS) are common syndromes that affect both clinical and surgical patients. This study describes the effects of a potent and specific N-methyl-d-aspartate receptor antagonist (MK-801) against oxidative stress in acute lung injury induced by intratracheal lipopolysaccharide (LPS) injection. This study was performed using male Wistar rats weighing 200-250g.

Anti-inflammatory and immunomodulatory effects of Ulomoides dermestoides on induced pleurisy in rats and lymphoproliferation in vitro.

The following study aimed to evaluate, in vitro and in vivo, the anti-inflammatory effect of Ulomoides dermestoides, a beetle commonly used as a remedy for a variety of diseases including respiratory disorders and asthma. We used an acute inflammation model of injury, injection of carrageenan into the pleural cavity of rats. The rats were treated intraperitoneally with the aqueous extract of U.

N-methyl-D-aspartate glutamate receptor blockade attenuates lung injury associated with experimental sepsis.

Background: The aim of this study was to examine the effects of the N-methyl-D-aspartate receptor (NMDAR) channel blocker dizocilpine (MK-801) on lung injury in rats submitted to experimental sepsis induced by cecal ligation and perforation (CLP).

Methods: Adult male Wistar rats submitted to CLP were given a single systemic injection of MK-801 (subcutaneously at 0.3 mg/kg) administered 4 or 7 h after CLP induction.

Fructose-1,6-bisphosphate inhibits in vitro and ex vivo platelet aggregation induced by ADP and ameliorates coagulation alterations in experimental sepsis in rats.

Sepsis is a systemic response to an infection that leads to a generalized inflammatory reaction. There is an intimate relationship between procoagulant and proinflammatory activities, and coagulation abnormalities are common in septic patients. Pharmaceutical studies have focused to the development of substances that act on coagulation abnormalities and on the link between coagulation and inflammation.

Intravenous toxicity of fructose-1,6-bisphosphate in rats.

Fructose-1,6-bisphosphate (FBP) is a bisphosphorilated sugar with a protective action against events that lead to cellular damage. The toxicity of the drug was assessed when administered intravenously in Wistar rats in doses of between 250 and 4000 mg/kg. Ionic calcium, total calcium, inorganic serum phosphate and the electrocardiographic profile of these animals were assessed.

An assessment of fructose-1,6-bisphosphate as an antimicrobial and anti-inflammatory agent in sepsis.

Tissue lesion mechanisms provoked by sepsis include the infectious process, inflammation, and cellular energy deficit. We chose to test fructose-1,6-bisphosphate (FBP) because of its possible anti-inflammatory and antimicrobial actions. Wistar rats were used and divided into three experimental groups: a control group (n=10), in which a capsule was introduced into the peritoneum of the animals; a septic group (n=10), in which a capsule containing non-sterile fecal matter was introduced together with Escherichia coli (1.
