Polymorphonuclear invasion of the wounded rat cornea is quantitatively described. The inflammatory cells enter the wounded tissue during the 5th postoperative hour. They steadily increase in number until they reach a maximum between 24 and 36 hours and return to normal by about the 6th day. Six hour
Experiments in rats suffering from primary acute adjuvant inflammation showed independent changes in serum acute phase protein concentration and macroscopic paw inflammation during antiinflammatory treatment: soybean trypsin inhibitor and horse-radish peroxidase caused antiinflammatory effects but
In adjuvant-arthritic rats the carrageenin edema of the non-arthritic hind paw was significantly inhibited 24 hours and 3 days after adjuvant injection, but the edema was not influenced at day 14 when the acute phase reaction was still evident and increased anew. Inhibition of the edema in the
1. Inflammatory responses were induced by the injection of carrageenin into the rat paw and lymph was collected by cannulation of the thoracic duct. Cell-free lymph samples were intracutaneously injected into a second group of rats to measure vascular permeability activity by local exudation of
Several nonsteroid anti-inflammatory agents were evaluated for their capacity to modulate phagocytosis by and lysosomal enzyme secretion from polymorphonuclear neutrophils. During cell contact with and phagocytosis of serum-treated zymosan particles, guinea-pig neutrophils demonstrated a selective
BACKGROUND
The toxicity of Dieffenbachia picta, an ornamental plant, arises from its ability to cause painful edema of oral mucous membranes, buccal ulcerations, and tongue hypertrophy after chewing on the stem or contact with the sap.
OBJECTIVE
We compared the anti-inflammatory effect of eugenol
1. Human endothelial cells express proteinase-activated receptor-2 (PAR-2), inflammatory cytokines and trypsin (EC 3.4.21.4). However, little is known about the mechanism through which trypsin induces cytokine release from endothelial cells. 2. In the present study, we investigated the effect of
Acute pancreatitis is a life-threatening inflammatory disease characterized by abdominal pain of unknown etiology. Trypsin, a key mediator of pancreatitis, causes inflammation and pain by activating protease-activated receptor 2 (PAR(2)), but the isoforms of trypsin that cause pancreatitis and
Penetration of skin by cercariae of Schistosoma mansoni is associated with a local inflammatory response characterised by leukocyte accumulation and tissue swelling. The significance of the inflammation and its relevance to infection of the host is unknown. In this study, we have investigated the
1. Injections of carrageenin (1,25 mg/kg i.v.) from the 1st to the 3rd day and then each 2nd or 3rd day inhibited paw swelling in adjuvant arthritis of the rat during the time of treatment. Injections from the 11th to the 15th day were ineffective. The level of plasma kininogen was slightly
Phenoloxidase (PO) activity was examined in the tunic tissue of Ciona intestinalis following lipopolysaccharide (LPS) intratunic injection. Tunic homogenate supernatant (THS), assayed with the Dopa-MBTH reaction, displayed Ca(2+)-independent PO activity that was raised by LPS and further enhanced by
Bradykinin is a potent pain-producing substance, yet little is known about its role in inflammation. The present study measured circulating levels of immunoreactive bradykinin in a clinical model of acute inflammation (oral surgery) and chronic inflammation (rheumatoid arthritis) and in the rat
Although principally produced by the pancreas to degrade dietary proteins in the intestine, trypsins are also expressed in the nervous system and in epithelial tissues, where they have diverse actions that could be mediated by protease-activated receptors (PARs). We examined the biological actions
OBJECTIVE
BMS-196843 (Oncostatin M) is a therapeutic recombinant protein in development. Scale-up process changes led to unexpected instability of the bulk drug substance solution during storage. A product with an apparent higher MW than the parent protein was observed by the size-exclusion
The writhing reaction in mice induced by kaolin, a factor XII activator, was studied. An intraperitoneal injection of kaolin clearly induced a writhing reaction in a dose-dependent fashion, and the reaction disappeared about 10-15 min later. The writhing reaction reached a peak at 5-10 min after the
